MANCHESTER C 13:00 - 17:00 Postgraduate Course: Metastatic Disease – When To Intervene And Who To Call? Course Chair: Fumio Konishi, MD Course Moderator: Michael J. Stamos, MD Course Description: In patients with stage 4 colorectal cancer, treatment of any present metastatic disease represents the only chance of potential cure. Appropriate patient selection and appropriate timing have always been important factors to determine. Newer tools, particularly new imaging modalities have apparently improved the outcome of many patients, primarily due to better patient selection. More recently, improvements in our adjuvant therapy armamentarium have also opened up the possibility and hope for patients previously deemed incurable. This symposium will help synthesize these issues and others important in the care of the stage 4 colorectal cancer patient, and help understand the possibilities offered by multidisciplinary interventions. Course Objectives: At the conclusion of this course, participants will be able to: MANCHESTER A-B • Understand currently accepted criteria for defining resectability of liver metastases • Understand the impact and importance of extra hepatic metastases in the treatment algorithm of patients • Understand the role of oophorectomy and resection of peritoneal implants • Identify patients with presently unresectable liver metastases that could be downsized and made resectable through appropriate treatment and understand these treatment options Follow-up After Apparently Successful Colorectal Cancer Surgery.

ABSTRACT BOOK Podium Papers COLORECTAL CANCER AND RESEARCH I S003 WITHDRAWN S001 OBJECTIVE CRITERIA FOR GRADE 3 IN EARLY INVASIVE COLORECTAL CANCER, Hideki Ueno PhD, Yojiro Hashiguchi PhD, Yoshiki Kajiwara MD, Kazuo Hase PhD, Hidetaka Mochizuki PhD, National Defense Medical College Background: In early invasive colorectal cancer, many authors reported that histological feature of grade 3 (G3) was a trustworthy risk factor of nodal involvement and was indicating the necessity of additional lapalotomy after endoscopic polypectomy. However, the standardized criteria for objective definition of G3 have not been well documented. Aim: To determine the objective criteria to judge T1 colorectal cancer (CRC) as G3. Patients and Method: A total of 238 T1 CRC patients who underwent curative survery with nodal dissection were retrospectively reviewed pathologically. The extent of the component of poorly differentiated carcinoma (POR) and that of mucinous carcinoma (MUC) was classified into 3 levels, respectively. The standards used for the categorization were the presence of the POR or MUC component fully filled a microscopic filed of a 40x objective lens, and the number of poorly differentiated clusters. Results: The incidence of nodal involvement was most efficiently stratified when G3 was applied to tumors which had 10 or more poorly differentiated clusters in a microscopic field of 4x objective lens, or mucinous component fully occupied a microscopic field of 40x objective lens. It was 28. 0% in G3 tumors (n=77) and only 3. 7% in non-G3 tumors (n=162) (P<0. 0001). Multivariated analysis revealed that G3, vascular invasion and tumor budding were independently relevant to increasing risk of nodal involvement. Regarding these three factors as the risk of nodal involvement, the incidence of nodal involvement was 21. 7% (25/115) in risk-positive tumors, whereas it was only1. 6% (2/123) in no-risk tumors. Conclusions: We can have the criteria for the judgment of G3 by evaluating the number of poorly differentiated clusters and the area of mucin producing area using a microscopic field as standard, which promise to be useful to be standardizing the assessment of risk of nodal involvement of T1 CRC. S004 RISK FACTORS OF THE NODAL INVOLVEMENT IN T2 COLORECTAL CANCER, Yoshiki Kajiwara MD, Hideki Ueno PhD, Masayoshi Miyoshi PhD, Yojiro Hashiguchi PhD, Kazuo Hase PhD, Hidetaka Mochizuki PhD, Department of Surgery, National Defense Medical College Objective: To identify the risk factors related to the nodal involvement of patients with T2 colorectal cancer. Patients and Methods: A total of 244 patients who consecutively underwent curative resection of T2 colorectal cancer were pathologically reviewed. The parameters examined with new definition were: 1) tumor budding (BD) (an isolated cancer cell or a cluster composed of fewer than 5 cells), 2) poorly differentiated component (POR) (a region in which a cancer has no glandular formation), and 3) myxoid cancer stroma (MCS). Each parameter was evaluated with 2-grades system: BD+ (10 or more budding foci in a microscopic field of x200) and BD- (the others); POR+ (POR fully occupied the microscopic field of x400 and/or 10 or more solid cancer nests composed of 5 or more cells in a microscopic field of x40) and POR(the others); MCS+ (MCS region fully occupied the microscopic field of x400) and MCS- (the others). Results: Nodal involvement was observed in 54 patients (22. 1%). The parameters which were significantly associated with nodal involvement were lymphatic invasion (the incidence of nodal involvement: low-grade, 18. 8%; high-grade, 57. 1%; p<0. 0001), BD (BD-, 16. 3%; BD+, 29. 4%; p=0. 015), POR (POR-, 8. 4%; POR+, 29. 2%; p=0. 0002), and MCS (MCS-, 16. 9%; MCS+, 36. 4%; p=0. 0011). In multivariate analysis, highgrade lymphatic invasion, POR+, and MCS+ were independent risk factors for nodal involvement. In T2 lower rectal cancer (85 patients), the nodal involvement rate was 32% in patients with risk factors (15% in 35 patients with one factor, 58% in 12 patients with two factors, and 100% in 4 patients with three factors), which was significantly higher than that in 35 patients with no risk factors (6%; p=0. 008). Conclusions: In T2 colorectal cancer, the important risk factors of nodal involvement were high-grade lymphatic invasion, POR+, and MCS+. Local resection as a gtotal biopsyh, which could evaluate the risk of nodal involvement before laparotomy, may be one of the treatment strategies for poor-risk patients with T2 lower rectal cancer S002 PROGNOSTIC VALUE OF PERITONEAL CYTOLOGY AND PERITONEAL DISSEMINATION IN COLORECTAL CARCINOMA, Takeshi Nishikawa MD, Toshiaki Watanabe PhD, Eiji Sunami PhD, Hirokazu Nagawa PhD, Department of Surgical Oncology, the University of Tokyo Background: The significance of peritoneal cytology as earlier prognostic marker has been examined in cancer of several organs, especially in gastric cancer. However in colorectal cancer the meaning of positive peritoneal cytology remains controversial. The aim of this study was to reveal the prognostic significance of peritoneal cytology in colorectal cancer and the association between peritoneal dissemination and peritoneal cytology. Methods: From January 1997 to December 2005, 1128 colorectal cancer patients who underwent laparotomy in our department were studied. Intra operative peritoneal cytology was performed on 410 patients whose cancer had invasion of the serosal surface or beyond. Results: 31 patients (7. 6%) showed positive peritoneal cytology. Patients with negative peritoneal cytology revealed a significantly better cancer-specific survival rate at 5 years than those with positive peritoneal cytology (negative cytology: 62. 5%, positive cytology: 21. 7%, P<0. 0001). However, among patients with positive cytology, 60. 0% of patients without peritoneal dissemination and liver metastasis achieved 3years disease-free survival. Intra operative peritoneal cytology was performed on 42 patients with peritoneal dissemination. Among 20 patients with peritoneal dissemination and positive cytology, no one achieved three years survival after operation. However, among 22 patients with peritoneal dissemination and negative cytology, 13 patients had received curative resection and 4 patients (30. 8%) achieved three years disease free survival. Conclusion: Patients with negative peritoneal cytology showed a significantly better 5year survival rate than those with positive peritoneal cytology. Furthermore, regarding patients with positive peritoneal cytology and no peritoneal dissemination or patients with peritoneal dissemination and negative peritoneal cytology, when curative resection was performed, long-term cancer-free survival can be expected. www.isucrs.org/ S005 DIRECT HERPES SIMPLEX VIRUS 1 (HSV-1) DELIVERY INTO RECTAL ADENOCARCINOMA IN MICE RESULTS IN AN EFFICIENT ANTI-TUMOR EFFECT, Yair Edden MD, D Kolodkin-Gal PhD, G Zamir MD, E Pikarsky MD, A Panet PhD, A J Pikarsky MD, Hadassah Hebrew University Medical Center, Hebrew University - Hadassah Medical School, Jerusalem, Israel Purpose: Cancer of the rectum is a common clinical problem. Because of its anatomical location in the pelvis and the proximity to the anal sphincters, rectal cancer poses a complex therapeutic challenge. The current standard of care combining neoadjuvant therapy followed by surgery has been shown to confer good survival rates and low local recurrence rates. This approach allows preserving sphincter function thus enhancing quality of life. We have recently shown that HSV-1 preferentially infects human colon cancer compared to normal colonic mucosa suggesting that HSV-1 based therapy may offer a novel therapeutic modality for rectal cancer. To determine the oncolytic effect of HSV-1 in a clinically relevant setting, we examined the effect of intra-tumoral delivery of HSV-1 into rectal adenocarcinoma in mice. Methods: Orthotopic rectal tumors were established by injecting mice colon adenocarcinoma cells (CT-26), stably transfected ex-vivo to express luciferase, directly into the submucosa of the distal rectum. The tumor response to viral therapy was assessed by imaging of luciferase expression in-vivo. Results: Intra-tumoral injection of HSV-1 resulted in complete arrest in tumor growth. HSV-1 increased animal survival by two folds. Histological analysis of the tumors injected with HSV-1 revealed a massive apoptotic response signifying a combined direct oncolytic and bystander effect. There was no HSV-1 gene expression or notable damage in the adjacent colonic mucosa or distant organs. Conclusions: These results demonstrate the efficacy of HSV-1 delivery into orthotopic rectal cancer and may provide the basis for a novel clinical therapeutic neoadjuvant modality for rectal cancer. 35 ABSTRACT BOOK Podium Papers S006 FACTORS PREDICTIVE OF LONG TERM FAILURE OF ARTIFICIAL BOWEL SPHINCTER. , H Ying Jin MD, V Ka Ming Li MD, Nestor Pulido MD, Benjamin Person MD, H Wang MD, D Sands MD, E Weiss MD, J Nogueras MD, S Wexner MD, Cleveland Clinic Florida Background: Artificial bowel sphincter (ABS) implantation is one of many operative treatments for fecal incontinence (FI). Late stage complications of ABS such as erosions and skin and rectal ulcerations and device malfunction may result in device explantation. This study aimed to assess the risk factors for latestage complications associated with ABS implantation. Methods: All patients who had an ABS implanted for FI were included in the study. Those patients whose ABS was explanted prior to device activation were excluded from analysis. Kaplan Meier survival curve was applied to evaluate the cumulative risk of the ABS explantation. Cox regression was applied to analyze the risk factors related to explantation. Results: From January 1998 to May 2007, 51 ABS devices were implanted in 47 patients; 18 were explanted prior to activation because of early stage infection. Thus, 33 (64. 7%) functional ABS device implantations were included in the study. The mean age was 49+13 (19-79) years; 7 (21. 2%) were male. The mean Cleveland Clinic Florida (CCF) FI score was 18+1. 4 (16-20). In 18 patients (54. 5%), the etiology of FI was secondary to imperforate anus, 8 (24. 4%) patients had obstetric injury or anorectal trauma, 3 had low anterior resection for rectal cancer, 3 were secondary to neurogenic causes, and 2 were related to spinal injury. 10 (30. 3%) patients had prior ABS implantation and 18 (54. 5%) had a history of sphincteroplasty, perineal reconstruction, or sphincter repair; 6 had a preoperative stoma. During a mean follow up of 39+28 (5-108) months, 9 patients had device malfunction and recurrent FI, 6 developed skin or rectal erosion, 5 had persistent perianal pain, 2 developed device migration, 2 suffered from constipation, and 1 developed a hematoma over the labia majora. 13 (39. 4%) ABS devices were explanted for late-stage complications. Evaluation with KaplanMeier survival curve showed that the one and two year cumulative risk of ABS explantation was 9. 7% and 13%, respectively. After 2 years, the risk of ABS explantation sharply increased and the third and fourth year risk increased to 47% and 53%, respectively. 5 year cumulative risk was 58%. Cox regression analysis showed that explantation of ABS was not related to patient’s age, gender, etiology of FI, CCF FI score, body mass index, history of perianal procedure or infection, presence of a defunctioning stoma, or the timing of the procedure. Conclusion: The number of ABS devices explanted increased over time. The majority of late stage complications were technical and related to the device and no predictive patient-related factors were identified. Further refinement of the device itself and for the technique may be necessary. S007 MICROMETASTASES IN BONE MARROW OF COLORECTAL CANCER PATIENTS: NO EVIDENCE OF MALIGNANCY, D F Altomare MD, G Guanti MD, J Hoch MD, M Vician MD, Z Krivokapic MD, R Bergamaschi MD, Forde Health System, Forde, Norway; Bari University, Bari, Italy Background: To investigate whether disseminated epithelial cells (DEC) in the bone marrow (BM) of colorectal cancer patients are cancer cells clonal with the primary tumor and impact rates of liver metastases (LM). Methods: Prospective data on colorectal cancer patients were collected from five centers. BM aspirates were taken at laparotomy before primary tumor was resected for cure. Specimens were sent to a single lab. Colorectal cancer patients with LM at surgery were excluded. 3 x 106 bone marrow cells per patient were processed with monoclonal antibodies against cytokeratin 20. Mutations of APC or p53 genes and microsatellite instability (MSI) were assessed in primary tumor by single-strand conformation polymorphism. DEC in BM of primary tumor mutation or MSI-positive patients were isolated with immunobeads coated with magnetically labeled anti-HEA antibody and DNA screened for mutations. Cox proportional hazards regression analysis and Fisher’s exact test were used to assess statistical heterogeneity. LM-free curves were generated and compared using the Kaplan-Meier method and log-rank test, respectively. Variables were estimated by the maximum likelihood method. Results: 199 patients were enrolled. 162 patients were 36 ISUCRS XXII BIENNIAL CONGRESS available for analysis. No patient was lost to follow-up. A median of 24 (1-170) DEC were found in the BM of 117 patients. 22 patients developed LM at a follow-up of 36 months. APC or p53 mutations or MSI were found in primary tumor of 79 patients. Mutations and MSI were not found in DEC of BM of the same 79 patients. After excluding center 3 (12 patients), there was homogeneity on LM rates among centers with LM for age (p=. 5182) and center (p=. 1382). There was heterogeneity between centers with LM (145 patients) and one center without LM (5 patients) for pN (p=. 002). DEC in BM had no impact on LM rates (p=0. 14) Mutations of APC (p=0. 2115), P53 (p=0. 6354), or MSI (p=0. 8947) in primary tumor had no impact on LM rates. Conclusion: DEC in BM of colorectal cancer patients are not clonal with primary tumor, and, therefore, not malignant and have no impact on LM rates. S008 EARLY ARTIFICIAL BOWEL SPHINCTER INFECTION: CAN IT BE AVOIDED? A MULTIVARIATE ANALYSIS. , H Yin Jin MD, V Ka Ming Li MD, N Pullido MD, B Person MD, H Wang MD, D Sands MD, E Weiss MD, J Nogueras MD, S Wexner MD, Cleveland Clinic Florida Background: Artificial bowel sphincter (ABS) implantation can greatly improve function in appropriately selected patients with fecal incontinence (FI). However, the published rate of postoperative complications is more than 40%, the most serious of which is infection, ranging in incidence from 15 to 40%. The factors contributing to postoperative infection have not been clearly identified. Early stage infection (before ABS activation) may be related to the patient’s underlying condition, technical issues, and immediate postoperative events. This study focused on factors related to early stage infection with an aim to identify any avoidable factors for ABS infection. Methods: Factors related to the patient’s background, operative procedure, and postoperative events were analyzed. Chi square and Student t test were used for univariate analysis and logistic regression was used to multivariate analysis. Results: From January 1998 to May 2007, 51 ABS devices were implanted in 47 patients of a mean age of 48. 8+12. 5 (19-79) years; 43 (84. 3%) were female. The mean Cleveland Clinic Florida (CCF) FI score was 18+2 (16-20). 21 (41. 2%) patients developed infection, 18 (35. 3%) of who developed early stage and 3 (5. 9%) late stage infection. Of the latter group, one was related to erosion and the other 2 were secondary to fistula formation. All 18 patients with infection had their ABS devices explanted. Univariate and multivariate analysis found that the time to the first bowel movement (<2 days) and a history of perineal infection were related to early stage ABS infection. Conclusion: The time to first postoperative bowel movement and a history of perineal infection were risk factors for early stage ABS infection with the time to first postoperative bowel movement as an independent risk factor. A better regime of bowel preparation and a specially designed postoperative wound care program may be necessary to improve outcomes. COLORECTAL CANCER AND RESEARCH II S009 EFFECT OF COMPLETE REGRESSION AS A PROGNOSTIC FACTOR AFTER NEOADJUVANT CHEMORADIATION THERAPY IN LOCALLY ADVANCED RECTAL CANCER, Jonghyeon Park MD, Jiyeon Kim PhD, Department of Surgery, Chungnam National University Hospital, Daejon, Korea Purpose: Neoadjuvant chemoradiation therapy (NCRT) for locally advanced rectal cancer has tumor downstaging, which enhances curative resection and decreases local recurrence. The aim of this study is to evaluate the prognostic factor as tumor regression grade (TRG) after NCRT and radical surgical resection of locally advanced rectal cancer. Methods: From 1999 to 2003, 140 consecutive patients with biopsy proven, locally advanced rectal cancer (T3 or T4, or lymph node positive) were treated with 5-fluorouracil based chemotherapy and radiation, followed by radical surgical resection. The total radiation dose was 5040 cGy over 6 weeks. The radical surgical resection with total mesorectal excision was done 6 to 8 weeks after the completion of NCRT. Overall survival, disease free survival, local recurrence rate, and distant metastasis rate were investigated as TRG, retrospectively. Results: 126 patients (90%) were responded to radiation therapy. no response, partial response and complete response were 14 ABSTRACT BOOK Podium Papers (10%), 98 (70%) and 28 (20%), respectively. Overall survival and disease free survival of 3 years (n=140) were 91. 43% and 74. 29%, and those of 5 years (n=117) were 81. 20% and 67. 52%. Overall survival of 3 and 5 years of complete response group (CR group) were no statistically difference from those of residual group (92. 86% and 92. 31% vs 91. 07% and 78. 02%; p=0. 78, p=0. 10). Disease free survival of 3 and 5 years of CR group were significantly better than that of residual group (89. 29% and 88. 46% vs 70. 54% and 61. 54%; p=0. 048, p=0. 013). Conclusions: Complete remission after NCRT and radical surgical resection has its oncologic benefit in disease free survival in our study. S010 FACTORS AFFECTING THE PROGNOSIS OF PATIENTS WHO UNDERWENT RESECTION OF PULMONARY METASTASES FROM COLORECTAL CANCER, Keiichiro Ishibashi PhD, Masaru Yokoyama PhD, Kouki Kuwabara MD, Masatsugu Ishii MD, Toru Ishiguro MD, Tomonori Ohsawa MD, Norimichi Okada PhD, Moriyuki Matsuki PhD, Hideyuki Ishida PhD, Department of Digestive Tract and General Surgery, Saitama Medical Center, Saitama Medical University Purpose: This retrospective study investigated factors affecting the prognosis of patients who underwent resection of pulmonary metastases from colorectal cancer. Patients and Methods: A total of 50 patients with pulmonary metastases from colorectal cancer underwent pulmonary resection between May 1990 and August 2007. Patients age ranged from 39 to 91 years (median: 64 years), and the male-to-female ratio was three to two. The sites of the primary lesions were colon in 28, and rectum in 22. pTNM stage at resection of the primary lesion was as follows: stage II in 20, stage III in 9, and stage IV in 16Cand unknown in 5 The number of pulmonary metastatic lesions was one in 35 and two or more in 15. Twelve patients had undergone hepatectic metastatectomy prior to thoracotomy. The prognostic factors related to diseasefree and overall survival were analyzed by univariate and multivariate analysis. Results: The median three-year diseasefree survival and median 5-year overall survival were 40% and 41%, respectively. On univariate analysis by logrank test, patients with rectal cancer (P=0. 07) and elevated CEA level at thoracotomy (p=0. 07) tended to show a shorter disease-free survival. Patients with hepatic lesion(s) prior to thoracotomy (p<0. 01) and those with stage III/IV disease (p=0. 07) at resection of the primary lesion showed longer or tended to show longer overall survival. Multivariate analysis by Cox proportional hazard model showed that the presence of hepatic lesion(s) was the only determinant factor affecting overall survival (p<0. 01). Conclusion: Resection of pulmonary metastases from colorectal cancer should be carefully indicated for patients with prior surgery for hepatic metastasis. S011 EGFR EXPRESSION IN COLORECTAL CANCER, JiHoon Kim MD, Jae-Im Lee MD, Hyung-Jin Kim MD, Won-Kyung Kang MD, Seong-Taek Oh MD, Yoon-Suk Lee MD, Sang-Chul Lee MD, Jong-Kyung Park MD, Department of Surgery, The Catholic University of Korea Purpose: Epidermal growth factor receptor (EGFR) is a transmembrane cell surface receptor which has tyrosine kinase activity stimulated upon EGF or TNF-r binding. And it is known to regulate signal transduction, cell growth and apoptosis. Recently, the monoclonal antibody targeting EGFR was developed. In this study, we are trying to find out how many colorectal cancers express EGFR and the expression of EGFR has a relationship with other known prognostic factors. Materials and Methods: We carried out the immunohistochemical staining in surgical specimen of primary colorectal cancer from December, 2006 to September, 2007. One pathologist reviewed the slides and scored positive if more than 1% of the cells were stained. And the status of EGFR expression was compared to other prognostic factors. Result: There were 88 men and 61 women, and the average age of the patients was 63 years old (35-89). Among 149 specimens, 110 specimens (74%) were scored as EGFR positive. And there were no correlation between the status of EGFR expression and other prognostic factors such as sex, age, preoperative CEA levels, size of the tumor, location of the tumor, cell type of the tumor, TNM stage, neural invasion, venous invasion, or lymphatic invasion. Conclusion: EGFR immunohistochemical staining in the specimen of primary colorectal cancer was positive in 74% of www.isucrs.org/ the patients. But the expression of EGFR has no correlation with other prognostic factors. S012 ONCOLOGICAL OUTCOMES OF CURATIVE COLECTOMY VIA MINILAPAROTOMY FOR STAGE I, II AND III COLON CANCER, Keiichiro Ishibashi PhD, Masaru Yokoyama PhD, Kouki Kuwabara MD, Masatsugu Ishii MD, Toru Ishiguro MD, Tomonori Ohsawa MD, Norimichi Okada MD, Tatsuya Miyazalki PhD, Moriyuki Matsuki PhD, Hideyuki Ishida PhD, Department of Digestive Tract and General Surgery, Saitama medical Center, Saitama Medical University Background and Purpose: The feasibility, safety, and minimal invasiveness of our minilaparotomy method for colon cancer has been reported (Surgical Endosc 19:316-20, 2005). However, little is known about the oncological outcomes after this type of surgery. This retrospective study was performed to clarify the validity of our surgical approach in terms of oncological aspects. Patients and Methods: A total of 165 patients with colon cancer underwent curative surgery via minilaparotomy (skin incision, 6-7cm) between July 2000 and December 2006. Of these@patients, 126 (age:40-89 years, male/ female=76/50) were histologically confirmed to have stage I/II/III cancer (stage I;66, stage II;37, stage III;23). Sites of recurrence, disease-free survival, and overall survival were estimated. Results: A total of 6 patients developed recurrence (one in stage I, three in stage II, three in stage III). The initial sites of recurrence were the liver in one, lung in one, lymph node in one, peritoneum in two, liver + lung in one. Liver + peritoneum + bone in one. Malignant tumor(s) other than colon cancer developed in three patients. The cumulative 3-year disease-free survival rate and overall survival rate were 94. 3% and 92. 6%, respectively. These rates were identical to those for stage I/II/III patients who underwent conventional open surgery performed before Introduction: of the minilaparotomy. Conclusion: Our minilaparotomy is considered to be oncologically safe even for patients with stage I/II/III colonic cancer although longer follow-up is needed to conclude this issue. S013 ELECTROPHYSIOLOGIC CHARACTERISTICS OF HUMAN COLONIC SMOOTH MUSCLE, KJ Park PhD, EK Choe MD, JS Moon, Seoul National University College of Medicine, Seoul, South Korea Background: In human colon, two distinct electric pacemaker activities exist: one at the submucosal layer; and the other at the myenteric borders of the circular muscle layer. Purpose: The present study was undertaken to characterize the spontaneous electrical activity in the human colonic smooth circular (CM) and longitudinal muscle (LM) in the absence of any drugs. Materials and Methods: Muscle flaps were obtained during elective colon resections for nonobstructive neoplasms. Mucosal layer was removed (submucosal layer was left intact) and the muscles were transferred to an electrophysiological chamber perfused with Krebs-Ringer bicarbonate solution (KRB) in 37. 5C and pinned down. Parallel and cross-sectional flaps were used for CM and LM, respectively. Inner CM (n=11), outer CM (n=13) and LM (n=14) cells were impaled with glass microelectrodes filled with 3 M KCl with resistances ranging from 50 to 80 M¥Ø respectively. Transmembrane potential was measured by high-input impedance amplifier and outputs were displayed on an oscilloscope. Results were stored and analyzed by clampex soft ware. Measured parameters were resting membrane potential (RMP), amplitude, spike amplitude and frequency. Results: RMP, spike amplitude showed no difference in three layers. Regularly occurring waves were observed in all 3 layers, but there were significant difference in frequency between inner and outer CM (4. 85+/-2. 69/min vs 20. 40+/-3. 76/min; p=0. 00), inner CM and LM (4. 85+/-2. 69/min vs 23. 01+/-4. 36/min; p=0. 00), but not between outer CM and LM (p=0. 18). The amplitude of these regularly occurring waves also showed significant difference between inner and outer CM (22. 17+/-10. 872mV vs 12. 02+/-10. 01mV; p=0. 02), and between inner CM and LM (22. 17+/-10. 872mV vs 11. 52+/-4. 23mV, p=0. 01), but not between outer CM and LM (p=0. 98). Comparison of right and left colon showed that spike amplitude in outer CM was significantly higher in the right colon (right 25. 58+/-11. 80 vs left 15. 99+/-7. 17; p=0. 005), while spike amplitude in inner CM was higher in the left colon (right 18. 98+/-10. 01 vs left 21. 18+/-11. 37 ABSTRACT BOOK Podium Papers 20; p=0. 005). Conclusion: We have demonstrated that inner CM has distinct that electrophysiologic characteristic compared to outer CM and LM. Our results confirm that there are two distinct pacemaker activities (submucosal and myenteric border) and that these two pacemakers generate different electrical activities with resultant different electrical activities in the neighboring smooth muscle fibers. S014 MOTILITY PATTERNS IN SHORT SEGMENT OF HUMAN COLONIC TISSUE, EK Choe MD, KJ Park PhD, JS Moon, Seoul National University College of Medicine, Seoul, South Korea Background: Studies of human colon motility have usually been performed using small strips of muscle tissue, either circular (CM) or longitudinal (LM) muscles. However, overall motility is determined by progression of contractile activities within each layer and/or interaction between CM and LM layers. The present study was undertaken to characterize the motility patterns in a short segment of human colonic tissue. Method: Whole layer of 2X4cm sized segment of colon tissue containing taenia coli were obtained during colon resections for nonobstructive neoplasms. A stainless steel rod was place parallel to longitudinal muscle and placed at the organ bath which was perfused with Krebs-Ringer bicarbonate (KRB) solution and maintained at 36+/-1¡É. CM tension was recorded at three (oral, middle, aboral) sites and LM tension was recorded by perpendicular traction. Tension recording was performed using isometric strain gauge and transduced to Acknowledge soft by clips and SPSS T-test was used for analysis. Results: Total of 23 tissues were available for analysis. Dominant Regular waves (DRW) were identified in all cases and occurred with frequency of 0. 38+/-0. 32/min (amplitude: 16. 74+/-10. 28mN) in CM and invariably resulted in anterograde propagation (from oral to aboral side) in the CM layer, and also propagated to the LM layer resulting in similar frequency of contraction (0. 36+/-0. 37/min; amplitude 23. 21+/-14. 62mN). In 5 tissues, non-dominant waves (NDW) were identified in addition to DRWs (frequency: 0. 23+/-0. 10/min, amplitude: 22. 77+/-12. 40mN). The frequency (0. 51+/-0. 41/min) and amplitude (19. 07+/-19. 57mN) of the NDWs tended to be similar to DRWs, and some of the NDWs showed retrograde propagation (aboral to oral side), but none of these waves propagates antergradely nor resulted in contraction of the LM layer. No difference between right and left side of the colon was noted. Conclusion: In segment of human colon, regular contraction patterns propagating from oral to anal side in the CM, and consequently resulting in contraction of the LM was noted. On the other hand, in some of the tissues, non-propagating, or retrograde propagating contractions in the CM without contractions in LM were identified. Our results indicate that there is continuous contractile activity to move the colonic contents from oral to anal side in the short segment of human colon and that time sequenced CM to LM contraction may contribute to this purpose. S015 IDENTIFICATION OF MITOCHONDRIAL F1F0ATP SYNTHASE INVOLVED IN LIVER METASTASIS OF COLORECTAL CANCER, Min Ro Lee PhD, Jong Hun Kim PhD, Department of Surgery, Chonbuk National University Medical School Liver metastasis is a major cause of poor survival of colorectal cancer patients. In order to identify the proteins associated with liver metastasis in colorectal cancer, we have performed 2-DEbased comparative proteomic analysis of normal colon mucosa, primary colon cancer tissue, and corresponding metastatic tumor tissue in liver and the proteins identified were has been further validated by using immunohistochemical analysis of 67 triplet samples of normal colon-primary colorectal cancer-synchronous liver metastasis, and 251 colorectal cancers (a total of 318 colon cancers, 67 normal colons, and 67 synchronous liver metastasis) as well as in vitro invasion assay of the human colon cancer cell line, SNU-81. From the proteome assessment, the mitochondrial F1F0-ATP synthase (ATP synthase) a-subunit was identified as a protein that is up-regulated in liver metastasis, compared to the primary tumor. Immunohistochemical analysis confirmed a significant increase in expression of ATP synthase a- and d-subunits in synchronous liver metastasis, compared to primary tumor and normal mucosa, respectively. ATP synthase a- and d-subunits were overexpressed in 197 (78. 5%) and 190 (75. 7%) 38 ISUCRS XXII BIENNIAL CONGRESS out of 251 colorectal cancers, respectively. The overexpression of the a-subunit and d-subunit were significantly associated with liver metastasis (P<0. 05), as well as low histologic grade (P<0. 0001). The d-subunit also correlated with venous invasion (P=0. 026) and distant metastasis (P=0. 032). In stage III cancers, d-subunit expression was independently associated with poor survival (P=0. 017). Furthermore, transfection of siRNA targeted to the suppression of ATP synthase d-subunit resulted in a decreased of in vitro invasiveness of the human colon cancer cell line. Our overall findings demonstrate that increased of ATP synthase is associated with liver metastasis of colorectal cancer. S016 5-FLUOROURACIL-RELATED GENE EXPRESSION IN PRIMARY SITES AND HEPATIC METASTASES OF COLORECTAL CARCINOMAS, Shinichi Sameshima PhD, Shinichiro Koketsu PhD, Toshiyuki Okada PhD, Toshio Sawada PhD, Gunma Cancer Center Aim: The aim of this study was to investigate the correlation of the mRNA expressions of 5-fluorouracil-related genes in the primary sites and liver metastases of colorectal carcinomas. Materials and Methods: Patients with liver metastases from colorectal carcinomas were included (n=43). The expression ratios of mRNA to ƒÀ-actin of thymidine synthase (TS), dihydropyrimidine dehydrogenase (DPD), thymidine phosphorylase (TP), and oroteta phophoribosyl transferase (OPRT) were measured in primary and liver metastases of colorectal carcinomas by laser-captured microdissection and real time PCR. Results: The ratios for the expression of mRNA of TS, DPD, TP and OPRT between paired primary sites and liver metastases were significantly correlated. The mRNA expression ratios of DPD and TP showed a significant correlation in primary sites and in liver metastases. Conclusions: Enzymes of the primary colorectal carcinomas can be used in predicting the therapeutic efficacy of 5FU against liver metastases. COLORECTAL CANCER, BENIGN COLORECTAL DISEASE & FECAL INCONTINENCE S017 RISK FACTORS ASSOCIATED WITH LOCAL RECURRENCE AFTER NEOADJUVANT CHEMORADIATION COMBINED WITH TOTAL MESORECTAL EXCISION FOR LOCALLY ADVANCED RECTAL CANCER, Nam-Kyu Kim MD, Young-Wan Kim MD, Byung-Soh Min MD, Ki-Chang Keum MD, Jin-Sil Seong MD, Jung-Bai Ahn MD, Jae-Kyung Roh MD, Hoguen Kim MD, Department of Surgery, Yonsei University College of Medicine, Seoul, Korea Objective: Preoperative chemoradiotherapy is more advantageous than postoperative chemoradiotherapy in patients with clinical T3 or T4 or node-positive disease, especially in terms of reducing local recurrence rate and enhancing anal sphincter preservation. However, local recurrence is still a devastating problem, which is closed related to poor oncologic outcomes and patients’ quality of life. The purpose of this study is to investigate patterns of local recurrence and risk factors affecting local recurrence in patients with locally advanced rectal cancer who received preoperative chemoradiotherapy in combination with total mesorectal excision (TME). Methods: Between January 1994 and December 2004, medical records of 145 patients with locally advanced rectal cancer who received neoadjuvant chemoradiation (5-FU based chemotherapy and 5040Gy of radiation) with TME surgery were collected from the prospective colorectal database. All tumors were initially staged as cT3 or T4 regardless cN stage at the multidisciplinary team meeting on the basis of physical examination, abdominal computed tomography, and pelvic magnetic resonance imaging. Results: 26 patients (17%) had a local recurrence. Mean follow-up period was 40 months (3145 months), Mean time to local recurrence was 13 months (5-93 months). Patterns of local recurrence were ten cases (38. 5%) of pelvic wall recurrence, six cases (22. 2%) of anastomotic recurrence, and two cases of bladder recurrence. 3 year disease specific survival is 40. 5% in local recurrence group and 78. 8% in non-local recurrence group (p<0. 001). 50% of local recurrence occurred within 13 months and 92% of local recurrence was occurred within 3 years after surgery. On multivariate analysis, factors affecting local recurrence are less than 50 years of age (p=0. 039), positive circumferential resection margin (p=0. 001) ABSTRACT BOOK Podium Papers and lymphatic vessel invasion (p=0. 003) Conclusion: In patients with locally advanced rectal cancer who received neoadjuvant chemoradiotherapy with TME, Age younger than 50 years, positive circumferential margin, and lymphatic vessel invasion were statistically significant factors for local recurrence. For better oncologic outcomes, adjuvant intensified chemotherapy, intraoperative radiotherapy, or extensive surgery should be considerd in these patients having risk factors. S018 THE LONG-TERM RESULTS OF SURGERY FOR COLON CANCER IN JAPAN, Takashi Hirai PhD, Yukihide Kanemitsu MD, Koji Komori PhD, Tomoyuki Kato PhD, Aichi Cancer Center Operative procedures for colon cancer standardized in Japan by establishing “the Japanese classification for colon and rectal cancer” in these three decades. The level of curability that we have arrived at, and surgical factors to contribute to the results are evaluated. With those basic data of standardized surgical outcome, we are able to presume who may obtain the profit from which of postoperative adjuvant therapies. Patients and Methods: 1289 patients with single primary colon cancer excluding in situ carcinoma who underwent curative operation in our hospital during 1970 and 2003 are evaluated. None of the patients are lost to follow up. They are divided to the three period groups by year, the early period; 166 patients (1970-79), the middle period ; 341 patients(1980-89), the late period; 782 patients(1990-2003). Time trends in surgical treatment (especially extent of lymph node dissection), chemotherapy, and other oncological factors are studied. To estimate the effect of the factors on survival, KaplanMeier method, Cox hazard model were used. Results: Overall survival (OS) and disease free survival(DFS) improved over the study period: the five year OS and DFS ( the early, middle, late period, respectively) were Dukes Ai88%, 96%i26 ptsjA89%, 98% (61 pts)A93%, 98% ( 263pts ), N. S. , Dukes Bi78”, 82%i95 ptsjA87%, 86%i154 ptsjA86%, 91%i270ptsjj, N. S. , Dukes Ci60%, 62%i45ptsjA69, 70%i126ptsjA81%, 81%i249ptsjj, p<0. 05. The ratio of wide lymph node dissection which is consisted of the adequate resection of the colon and apical node dissection has increased from 34. 6% to 90%. The mean number of harvested lymph nodes has increased from 15 to 25. The curative surgical treatment of recurrent tumor varied a little (3%, 5. 3%, 4. 7%, respectively). Factors with impact on DFS by Cox hazard model were Dukes classification, a period, preoperative CEA. The wide lymph node dissection was not significant. But among wide lymph node dissection, 5-year survival in late period was superior(84% vs 71%) to the other. We presume that the procedure advancement in wide lymph node dissection obscured the result in multivariate analysis. Conclusion: The surgical treatment of colon cancer have chronologically resulted in improving the oncological outcome. Especially wide lymph node dissection for stage III might have largest impact on the improvement. But multivariate analysis could not prove the efficady of the wide lymph node dissection. S019 MOLECULAR PROGNOSTIC MARKERS IN COLORECTAL CANCER, Krasimir Ivanov MSc, Nikola Kolev PhD, Anton Tonev MD, Gergana Nikolova PhD, Anton Tonchev, Ivan Krasnaliev, Kalin Kalchev, University Hospital “St. Marina”, Medical University - Varna, Bulgaria Introduction: Despite the modest improvements in patient survival from colorectal cancer in the last few decades, the overall five-year survival rate remains at 40 to 45 percent. Surgical resection is the mainstay of treatment for colorectal cancer; however, nearly one-half of all patients who undergo a potentially curative resection will relapse because of undetected metastasis. The fact that the overall survival rate remains poor strongly suggests that the dissemination of these cells occurs early in the disease process and emphasizes the need for finding feasible diagnostic methods with sufficient sensitivity and specificity for evaluation of tumor aggressiveness. The p-53, MUC-2, Ki-67, VEGF, Bax, Bcl-2, Stat, MMP2 are markers, which could describe all the stages of carcinogenesis. There some questions remaining about their clinical value and hence most recent studies are utilizing a combination of factors. Aim: To clarify the usefulness of immunohistochemical molecular markers in predicting the metastatic potential and tumor behavior of colorectal cancer. Material and Methods: We evaluate the expression of those markers in group of 72 patients with colorectal carcinoma. www.isucrs.org/ We observed the relations between: 1) type of operation; 2) histological type; 3) clinical stage; 4) individual risk index (IRI), based on evaluated expression of tumor markers. Results: Achieving 100% successful rate in our study, we statistically analyzed the data received from marker’s expression. Based upon that, we calculated an IRI for every patient and divided the patients in 3 groups. A Group A, formed by 28 (38%) patients, which are with low clinical stage and worse molecular prognosis. A Group B, formed by 20 (27%) of patients had low tumor aggression and III or IV clinical stage and Group C, formed by the other 26 (35%) of the patients where is a correlation between the molecular and clinical stage prognosis. Conclusion: Multivariate analysis revealed that the IRI is independent prognostic factor for the tumor outcome. There were many evidences for the need of alteration of the surgical behavior in different stages according to biological nature of the tumor. Analysis of a combination of immunohistochemical molecular markers with the conventional diagnostic methods for colorectal cancer allows better prediction of the patients’ prognosis and more accurate and individualized therapeutic strategy. That could decrease the incidence of recurrence-rate and increse the survival. S020 ADJUVANT THERAPY FOR COLORECTAL CANCER PATIENTS RECEIVING NON-CURATIVE SURGICAL RESECTION, Giichiro Tsurita PhD, Takeshi Nishikawa MD, Yoshiki Takei PhD, Shinsuke Saito PhD, Takamitsu Kanazawa PhD, Shinsuke Kazama PhD, Eiji Sunami PhD, Hirokazu N Tsuno PhD, Hirokazu Nagawa PhD, Department of Surgical Oncology, the Graduate School of Medicine, the University of Tokyo Aim: To investigate the prognosis of patients receiving noncurative surgical resection for colorectal cancer. Patients: Among the primary colorectal cancer patients treated at our surgical department in the period between January 2001 and March 2006, 67 patients receiving non-radical (excluding cases with complete resection A and B) surgery were chosen. Rectal cancer cases receiving pre-operative irradiation were excluded. Method 1: Patients were divided into: FL group (n=32), i. e. , cases receiving intravenous 5-FU/Isovorin as the primary chemotherapy, oral chemotherapy group (n=5), i. e. , cases receiving either 5-FU/ leucovorin or TS-1 p. o. , FF group (n=11), i. e. , cases receiving FOLFOX or FOLFIRI, and CT(-) group, i. e. , cases not receiving any kind of chemotherapy. The effectiveness of the treatment, the survival period, and the development of side-effects were compared among these groups. Result 1: Regarding the effectiveness of the treatment and the survival period, cases in the FF group showed better results compared to the other 3 groups. Additionally, the cases in the CT(-) group had significantly poorer prognosis. Method 2: The patients receiving chemotherapy were divided, according to surgical procedure, into the following groups: resected group (n=33), i. e. , cases in which the primary lesion was resected, stoma group (n=8), i. e. , cases in which the primary lesion left, and non-surgery group (n=7), which included patients not receiving surgical resection, and the prognosis compared among them. Result 2: The survival period of the stoma group was significantly shorter than the other 2 groups. Conclusion: Chemotherapy should be preferentially indicated for patients with colorectal cancer in which radical resection is not feasible, especially when the primary lesion is left unresected. S021 OUTCOME OF PATIENTS WITH CLINICAL STAGE II OR III RECTAL CANCER TREATED WITHOUT ADJUVANT RADIOTHERAPY, Shin Fujita MD, Seiichiro Yamamoto MD, Takayuki Akasu MD, Yoshihiro Moriya MD, National Cancer Center Hospital Purpose: To clarify the indications for preoperative adjuvant radiotherapy for rectal cancer, the outcome of patients who underwent curative surgery without adjuvant radiotherapy was investigated. Methods: A total of 817 consecutive patients who underwent curative surgery for clinical stage II or III rectal cancer without preoperative adjuvant radiotherapy between 1988 and 2002 were reviewed. Results: The actuarial five-year local recurrence rate in the examined patients was 6. 2%. Univariate analysis showed that sex, pathological T classification (pT), clinical N classification (cN), pathological N classification (pN), tumor site, distance from the anal verge, type of surgery, pathological stage, a positive radical margin, lymphatic invasion, and venous invasion 39 ABSTRACT BOOK Podium Papers were significantly correlated with local recurrence. Multivariate analysis of preoperative factors identified cN, distance from the anal verge and sex as statistically significant risk factors for local recurrence. In patients with rectal cancer located less than 5 cm from the anal verge and with positive cN, the local recurrence rate was more than 10%. Conclusions: Patients with rectal cancer located less than 5 cm from the anal verge and with clinically positive lymph nodes should be given preoperative adjuvant radiotherapy. S022 LONG TERM OUTCOME OF ALTEMEIER’S PROCEDURE FOR RECTAL PROLAPSE, Donato F A MD, Gianandrea Binda MD, Ezio Ganio MD, Paola De Nardi MD, Marcella Rinaldi MD, Aldo Infantino MD, Giuseppe Dodi MD, Nicola Tricomi MD, Diego Segre MD, Giuseppe Di Giuro MD, Paolo Giamundo MD, Mario Pescatori, Dept of Emergency and Organ Transplantation, University of Bari, Italy Introduction: Many abdominal and perineal operations have been proposed for treating full-thickness rectal prolapse, but the best operation and correct indications have never been established. Perineal rectosigmoidectomy was proposed in 1976 by Altemeier butrarely applied in European countries, and its long term reliability is uncertain due to the low number of patients treated in each center. Patients and Methods: 93 patients (female/male ratio 7. 45, median age 77 years) underwent perineal rectosigmoidectomy and levatorplasty according to Altemeier, under general (30 pts), spinal (53 pts) or loco regional anesthesia (10 pts). In 14 of them the prolapse had previously been treated by other surgery; 68% suffered from major fecal incontinence, 6% from soiling. The mean duration of the operation was 125 min and the median length of the rectocolonic resected specimen was 15 cm. Coloanal anastomosis was fashioned manually in all but 3 cases where a 31mm circular stapler was used. Results: There was no postoperative mortality. Six major complications were observed (3 pelvic hematomas, one requiring surgical revision, 1 anastomotic dehiscence, one sigmoid perforation both requiring diversion, 1 pararectal abscess, and 2 late anal strictures), and 13 minor complications (5 transient anal pain and burning sensation, 2 a high temperature, 2 urinary retention, 2 cystitis, and 2 rectorrhagia). Mean post-operative hospital stay was 6 days (range 1-25). At a mean follow-up of 41 months (range 12-112 months) there was a complete recurrence rate of 18% (17 patients), treated with a repeated Altemeier’s operation in 6 cases, with a Delorme’s operation in 1, with a Wells’ rectopexy in 1, post anal repair in 1, anal bulking agents in 2 and SMN in 2, (4 patients were not re- operated). Incontinence had improved postoperatively in 30 cases (48%) (soiling or no incontinence), while in 2 pts it had deteriorated. Four of the patients with normal preoperative continence had postoperative soiling, which was transient in 1 patient. Conclusions: Perineal rectosigmoidectomy for full thickness rectal prolapse is a safe and effective treatment particularly for frail and old patients, with minimal postoperative morbidity, although the recurrence rate is not negligible and the restoration of continence unpredictable. S023 SURGICAL TREATMENT OF FISTULA-IN-ANO IN SINGAPORE - A RETROSPECTIVE STUDY OF 457 PATIENTS, Law Chee Wei, Iwan Kristian, Charles Tsang BihShiou, Dean Koh Chi Siong, Cheong Wai Kit, Division of Colorectal Surgery, Department of Surgery, National University Hospital of Singapore Objective: To evaluate the outcomes of patients who underwent surgical treatment for fistula-in-ano (FIA) from 2002 to 2006. Patients and Methods: All patients who underwent various types of surgery for FIA were studied retrospectively. All fistulae were classified using Parks’ classification and type of surgery performed was recorded. Specific end points studied included patient demographics, type of surgical procedure correlated with type of fistula, healing and recurrence rates. Results: 457 patients with a mean age of 41. 2 years were assessed. Male to female ratio was 4:1. Ethnic distribution was as follows: Chinese 66. 3%; Indian 16. 2%; Malay 13. 1% & others 4. 4%. 8. 5% of the patients had comorbidities (7. 2% diabetes mellitus; 0. 7% inflammatory bowel disease; 0. 4% rectal cancer & 0. 2% HIV positive). 45. 5% of them were evaluated preoperatively with endoanal ultrasonography. The distribution based on classification was as follows: inter- 40 ISUCRS XXII BIENNIAL CONGRESS sphincteric 209 (47. 3%), transs-phincteric 220 (49. 8%), suprasphincteric 2 (0. 5%), extra-sphincteric 4 (0. 9%) and horseshoe 7 (1. 6%). 26 patients (5. 7%) had secondary extension of fistulous track. 10 patients (2. 2%) had fistula operation performed prior to their presentation to our hospital. Fistulotomy was predominantly performed for low inter-sphincteric (85%) & low trans-sphincteric fistulae (71%). For higher complex fistulae, seton insertion followed later by definitive surgery was performed for high intersphincteric (69%) & high trans-sphincteric (68%) , supra-sphincteric (50%), extra-sphincteric (100%) & horseshoe fistulae (100%). The mean time before definitive surgery after seton insertion was 8. 9 weeks. The mean time to complete wound healing following surgery was 15 weeks. Fistulae persistence occured in 29 patients (6. 3%) whilst complete healing was achieved in 428 patients (93. 7%). The number of operations required for complete healing of the fistulae were distributed as follows: 1 operation: 333 (72. 9%), 2 operations: 76 (16. 6%), 3 operations: 15 (3. 3%) and 4 operations: 4 (0. 9%). After a mean follow up of 25 weeks, recurrence was noted in 12 patients (2. 6%). Conclusions: Our prevalence and distribution of FIA were similar to other studies. The outcomes following surgery guided by Park’s classification was satisfactory. S024 RECTAL IRRIGATION (RI) IS A BOON FOR CHRONIC CONSTIPATION - A PROSPECTIVE REVIEW, N Srinivasaiah MD, J Marshall RN, A Gardiner RN, G S Duthie MD, 1. Academic Surgical Unit, Castle Hill Hospital, University of Hull, Cottingham, United Kingdom Introduction: RI is used in faecal incontinence to relieve symptoms & improve quality of life. Literature on its role in constipation is limited. We aim to evaluate the causes for referral, efficacy & acceptability of RI using health outcome measures and assess effect on constipation. Methods: Review of prospective database of RI between 2002 & 2005. Symptom quantification using general standardized questionnaire (GSQ) determined efficacy. SF-36 & FIQL determined acceptability. Results: 175 patients’ data is used. 111(63%) patients found RI useful & 64(37%) unhelpful. The median follow up is 20 months. 79 of 175 patients were referred for constipation. 39 (49%) had success with RI. Patients who had successful RI, 56% said that they were “doing well” or “good improvement”, 26% said “dramatic improvement” whilst 17% said “limited” improvement using RI. Up to one third of the patients had RI once a day. GSQ, SF 36 and FIQL were analyzed pre & post RI for the whole group. Analysis is done only on successful cases. GSQ: Showed significant improvement in symptoms of straining, incomplete emptying, wind & urinary leak on stress post RI (95% CI). Visual Analog Scales show reduction in the severity of the problem. SF36: 71 of 111 patients completed SF36 pre RI & 43 of these also completed it post RI. In the whole group the median value for MCS increased from 43 to 55 and PCS increased from 47 to 66. PCS is significant (p value of 0. 03). In the group of patients with constipation the percentage increase in MCS & PCS is 20% and 33% respectively post RI. FIQL: Slight improvement in QOL is measured, but statistically insignificant. Conclusions: Constipation accounted for nearly half of referrals. RI was successful in nearly half of the referred population. SF- 36 demonstrates a significant improvement in the PCS. Generally speaking, RI offers symptomatic improvement & most patients find it acceptable.

Madrid. Spain Purpose: Different ways of management of fecal soiling or minor degrees of incontinence are usually unsuccessful. We report the technique and results of anal encirclement with a simple prosthetic sling, never used before as that, as a safe, easy to perform and cheap alternative option. Methods: Between 2004 and 2007, 12 patients (6 female) aged 18 to 73, underwent the technique here described for treating fecal soiling or incontinence of different etiology ( iatrogenic 4, obstetric 2, traumatic 2, neuropatic 2, mixed 2) after failure of previous sphincteroplasty and conservative management. Patients were assessed preoperatively and at ABSTRACT BOOK Podium Papers regular intervals clinically and functionally (manometry, JorgeWexner Fecal Incontinence Score, amount and episodes of leakage, each person serving as his or her own control). All patients were operated on by the same surgeon and data were recorded by an independent coordinator. The operation is performed under local or regional anaesthesia in the lithotomy position. Through four to five small perianal incisions the flat part of a Jakson-Pratt ® drain is inserted 2 cm deep encircling the anus. The technical details of the procedure are shown. Results: Complications were related to local infection requiring removal (2), breaking of the sling requiring replacement (1) and fecal impaction (1). In 3 patients a neoencirclement was performed. Pre- and postoperative mean resting pressure were 54 mm Hg (range 8 -88) and 72 mm Hg (range 52-90) respectively. No differences were found between mean pre and postoperative squeeze pressures (108 mm Hg and 108 mm Hg respectively). Jorge- Wexner mean preoperative score was 14. 6 (range 2-20) while postoperative score was 3 (range 1-7). All but 1 patient improved the clinical status. Conclusions: This is a simple technique which may improve the continence status in patients with soiling and variable degrees of incontinence, when other alternatives have failed or more sophisticated techniques are not available. S026 ANAL ELETROMANOMETRY AND BI-DIMENSIONAL ULTRASOUND EVALUATION OF FECAL INCONTINENCE: IS THERE A CORRELATION?, Jose Paulo T Moreira MD, Hélio Moreira Jr MD, Hélio Moreira PhD, Almeida C Arminda MD, Issac R Raniere MD, Coloproctology Service, Federal University of Goiás, Brazil Introduction: The complex mechanism of anal continence occurs due to the neuromuscular integrity of the anal canal, consistency of the intra-rectal content, rectal capacity and sensibility. Fecal incontinence is a common occurrence among women and may be developed after anal surgical procedures, anal traumas such as during vaginal delivery, or due to idiopathic neuropathy of the pudendal nerves. New advances in anorectal physiology tests allowed a better evaluation of these patients, especially anorectal eletromanometry as anal US. Aim: Evaluate the correlation between Anal Eletromanometry and Anal US in patients with fecal incontinence. Methods: 61 patients with fecal incontinence who had undergone EMN and Anal US were analyzed from our database program between jun/2006 to sept/2007. Resting and squeeze pressures, and muscular anatomy of the 3 thirds of the anal canal were recorded and evaluated. Results: Approximately 75% of the patients have had sphincter defects of anal US. Defects of the external sphincter of the anus were the lesions observed more frequently (almost half of the patients). Defects of the internal anal sphincter isolated were detected in about 1/3 of the patients and the majority of the cases were due to iatrogenic etiology, such as surgical procedures. The correlation between defects of the internal and external anal sphincter (observed by anal US) with resting and squeeze pressures of the anal canal (observed by EMN) was 71% and 73% respectively. About 20% of the patients who had any grade of sphincter defect by anal US had normal resting and squeeze pressures by EMN, showing pure correlation between the tests. Among the patients without sphincter defect by anal US, in 1/3 of them the EMN showed low anal sphincter pressures. Conclusion: EMN and anal US were elucidative methods in the investigation of patients suffering for fecal incontinence (the correlation between both tests is up to 70%). However, 20% of patients with sphincter defects had normal anal pressures. Therefore, we conclude that both tests are important and complimentary in the evaluation patients with fecal incontinence. S027 FACTORS AFFECTING THE SUCCESS OF SACRAL NERVE STIMULATION FOR FECAL INCONTINENCE, Donato F Altomare MD, Marcella Rinaldi MD, Pierluigi Lobascio MD, Pierluca Sallustio MD, Fabio Marino MD, Ramona Giuliani BS, Vincenzo Memeo MD, Dept of Emergency and Organ Transplantation, University of Bari, Italy Sacral Nerve Stimulation (SNS) is a recognized and effective treatment for fecal and urinary incontinence. Nevertheless, up to 30-50% of the tested patients are unresponsive to this technique www.isucrs.org/ for unknown reasons and since SNS is an expensive procedure, identification of the factors predictive of success is highly desirable. (PNE test). Patients: 76 patients (female/male ratio= 0. 77, mean age 57 y) with fecal incontinence have been tested for SNS. 41 with passive incontinence and 28 with urge incontinence, while the remaining cases had a mixed or undetermined type of incontinence. The cause of incontinence was idiopathic in 36, iatrogenic in 26, neurologic (including spinal lesions) in 9. We tested 43 pts with a temporary monopolar electrode while 33 had a quadripolar electrode implanted. All under local anesthesia. Three of them had already had an unsuccessful dynamic graciloplasty and one an artificial bowel sphincter. The severity of fecal incontinence was tested with the AMS and Wexner’s score. A positive test is defined as a reduction by at least 50% in at least one of the severity scores. Results: A positive test was obtained in 38 pts (50%) and 30 (39. 5%) of them were definitely implanted with a permanent stimulator (Interstim Medtronic Italia). The remaining patients refused the implantation (3), or no longer complained of fecal incontinence after removal of the temporary test (2), or else are awaiting implantation. Accidental removal was recorded in 6 of the monopolar electrodes, infection in one of them. The test was positive in 6 of the 10 patients with diabetes but only 4 of them were definitely implanted. The 2 groups were comparable regarding age, duration of incontinence, anal manometry, PNTML, AMS score and diabetes. The monopolar electrode test (PNE test) was able to elicit positive responses in 18/43 patients (42%), while the new quadripolar electrode test was positive in 20/33 (61%) p=0. 01. Passive incontinence responded to this treatment in 21/41 cases (54%), while urge incontinence had a good outcome in 13/28 (46%), p=NS. A positive response to the SNS was obtained in 33. 3% of the males compared with the 47. 1% of the females p= NS. Patients with idiopathic incontinence had significantly higher response rate p=0. 022. Multivariate logistic regression analysis shows that only the use of a quadripolar electrode was the single independent variable predicting the outcome with an OR of 5. 58. A trend toward significance was observed for the female sex, idiopathic cause and Wexner’s score. Conclusions: Female patients with passive, idiopathic incontinence may have better probability to respond to temporary SNS but the use of the self retaining quadripolar electrode is the only factor significantly related to the success rate. COLORECTAL CANCER, INFECTIONS AND STOMAS S028 INTERSPHINCTERIC RESECTION VERSUS STAPLED COLOANAL ANASTOMOSIS FOR LOW RECTAL CANCER, Bong Hwa Lee MD, Hyoung-Chul Park MD, Hallym University College of Medicine, Seoul, South Korea Purpose: Local control and functional results of intersphincteric resection are controversial in Asian - low BMI patients, even though it might provide chance to avoid permanent colostomy. We tried to evaluate functional and oncologic risk of intersphincteric resection, compared with stapled coloanal anastomosis, in patients of low rectal cancer. Methods: Patients with low rectal cancer underwent intersphincteric resection with hand-sewn anastomosis (ISR) or coloanal anstomosis with staple (stapled CAA) were retrospectively analyzed. Results: From 1999 to 2006, 85 patients were enrolled. The distance between anal verge and lower margin of tumor was 3. 4 -0. 8 cm (Range 2-5 cm) in ISR group and 4. 9 -0. 8 cm (Range 3-7 cm) in stapled CAA. The mean of body mass index was 23 (Range 18-32). The patients complained intolerable anal incontinence (Kirwan뭩 class >2) in 35% of ISR group and 9% in stapled CAA (P<0. 02) postoperatively. Local recurrence rate was greater in ISR group (15%) than in stapled CAA (2%, P<0. 04). There was no significant difference in distant metastasis between both groups. The disease free survival rate was 80. 8% and 91. 2% at three years in ISR group and stapled CAA, respectively. Complications such as urinary incontinence and sexual function in male patients were not different significantly in both groups. Conclusions: Intersphincteric resection with hand-sewn anastomosis could be worse than stapled coloanal anastomosis in function and local recurrence. This may indicate that careful selection should be required for intersphincteric 41 ABSTRACT BOOK Podium Papers resection even if stapled anastomosis cannot be applied due to narrow distal resection margin.

Methods: At 1, 3, and 5 years after surgery, functional outcome was compared between 48 patients with J-pouch reconstruction (J group) and 51 with straight anastomosis (S group), using a 17item questionnaire (overall best, 0; overall worst, 26). Reservoir function was evaluated manovolumetrically. Results: At 5 years, patients with ultralow anastomoses (less than 4 cm from anal verge) had fewer bowel movements during day or night, and less urgency and soiling in the J than S group. At that time, patients with low anastomoses (5 to 8 cm above the verge), had fewer bowel movements at night and less urgency in the J than S group. Manovolumetric results were better in the J than S group for both anastomotic levels. Functional scores improved significantly over time for both anastomotic levels, especially in the S group. Mean scores with ultralow anastomoses were J group, 5. 6 at 1 year vs. 5. 3 at 3 years (P=0. 0304) vs. 3. 7 at 5 years (P<0. 0001); and S group, 10. 2 at 1 year vs. 9. 6 at 3 years (P=0. 0063) vs. 7. 3 at 5 years (P<0. 0001). Mean scores with low anastomoses were J group, 3. 4 at 1 year vs. 3. 1 at 3 years (P=0. 0052) vs. 2. 1 at 5 years (P=0. 0003); and S group, 5. 2 at 1 year vs. 3. 8 at 3 years (P<0. 0001) vs. 2. 7 at 5 years (P<0. 0001). Manovolumetric results improved overtime in both groups. Conclusions: Functional outcome improved in the J and especially the S group over 5 years. However, function was better in the J than S group at all time points. S030 ACCURACY OF MAGNETIC RESONANCE IMAGING AND TRANSANAL ULTRASONOGRAPHY TO PREDICT PATHOLOGIC STAGE AFTER PREOPERATIVE CHEMORADIOTHERAPY FOR RECTAL CANCER, Sang Nam Yoon MD, Chang Sik Yu MD, Ah Young Kim MD, Dae Dong Kim MD, Ui Sup Shin MD, Jin Cheon Kim MD, Colorectal Clinic, Department of Colon and Rectal Surgery, and Radiology, University of Ulsan College of Medicine and Asan Medical Center Background: Preoperative chemoradiotherapy (PCRT) is currently the main neoadjuvant therapy used to treat locally advanced middle and low rectal cancer. Preoperative magnetic resonance imaging (MRI) and transanal ultrasonography (TUS) was hoped to provide information about the effects related to PCRT. Purpose: The aim of this study was to evaluate the correlation between pathologically verified tumor stages and clinical stages predicted by MRI and TUS after PCRT. Methods: The study subject was 165 patients with mid or low rectal cancer who underwent surgery after PCRT between January 2006 and June 2007 and for whom both MRI and TUS were tested. The total dose of radiotherapy was 50 Gy and it was delivered to the patients with 2 Gy per day and 5 times per week for 5 weeks. Chemotherapy regimen was oral Xeloda (1, 650 mg/m2 divided by 2) for 5 weeks during radiotherapy and a standard regimen with 5-fluorouracil with leucovorin was also used for some patients. Results: The overall predictive accuracy of MRI and TUS in T stage was 45. 5% and 44. 8%, respectively, whereas overstaging and understaging occurred in 50. 3% and 4. 2% in MRI and 49. 1% and 6. 1% in TUS. In N stage, accurate staging of MRI and TUS was noted in 43. 6% and 66. 7%, respectively, whereas overstaging and understaging occurred in 50. 3% and 6. 1% in MRI and 13. 3% and 20% in TUS. 42 ISUCRS XXII BIENNIAL CONGRESS Conclusions: There was poor agreement between clinical staging by MRI and TUS after PCRT and pathologic staging in both T and N stages. Most of the inaccuracy in T and N stages was caused by overstaging, especially with T0-T2 tumors. The problem might be that it cannot completely differentiate fibrosis from viable residual tumors after preoperative chemoradiotherapy. Key words: Rectal cancer, Preoperative chemoradiotherapy, MRI, Transanal ultrasonography S031 EFFECTS OF SURGICAL TIMING ON PROCTECTOMY COMPLICATIONS AFTER LONG COURSE NEOADJUVANT THERAPY, Emre Balik MD, Metin Keskin MD, Suleyman Bademler MD, Burak Ilhan MD, Sumer Yamaner MD, Turker Bulut MD, Yilmaz Buyukuncu MD, Necmettin Sokucu MD, Ali Akyuz, Dursun Bugra, Istanbul University, Istanbul Faculty Of Medicine, General Surgery Department Aim: Our aim was to find out the alterations of the early and the late-term postoperative complications between the two groups of rectal cancer patients having been operated at the end of either the 4th, or the 8th week following neoadjuvant therapy (NAT). Method: 146 patients who had been operated following neoadjuvant chemo-radiotherapy for rectal cancer between October 2002 and November 2007 were investigated retrospectively. According to the time of operation after the Rx&Cx, surgical technique, intra-operative, early and late postoperative complications were evaluated. Results: Seventy five patients (51%) were operated at the end of the 4th week and 71 patients (49%) were operated at the end of the 8th week following NAT. The mean follow-up period was calculated to be 24 months(1-62 months). The group of 75 patients operated at the end of the 4th week consisted of 41 male (54. 5%) and 34 female (45. 5%) individuals with a mean age of 54 (19-84). The group of 71 patients operated at the end of the 8th week consisted of 40 male (56%) and 31 female (44%) individuals with a mean age of 51, 9 (20-77). No intra-operative or early postoperative mortality was observed. In the “4th week group”, the intra-operative complication rate was 9, 3% (n=7) , the early postoperative complication rate was 21, 3% (n=16) and the late-term complication rate was found to be 8% (n=6). The major complications were considered to be anastomotic leakage and abdominal wound dehiscence (4 patients) whereas the other complications were accepted to be minor. On the other hand, in the “8th week group”, the intra-operative complication rate was 5, 6% while the early postoperative complication rate was calculated to be 28% and the late-term complication rate was found to be 12%. Conclusion: Although a definitive conclusion can not be reached because of the limited number of patients and the lack of the complete exact late-term results, it can be stated that no statistically significant difference could be established due to the intra-operative, early postoperative and late-term complications between these two groups of patients that had been operated either at the end of the 4th, or the 8th week following their neoadjuvant theraphy S032 THE FREQUENCY OF MICROSATELLITE INSTABILITY IN MULTIPLE PRIMARY COLORECTAL CANCER AND METACHRONOUS COLORECTAL CANCER, Toshimasa Yatsuoka MD, Kiwamu Akagi MD, Tsutomu Ishikubo MD, Shinichi Asaka MD, Yoji Nishimura MD, Hirohiko Sakamoto MD, Yoichi Tanaka MD, Division of gastroenterological surgery and cancer genetic diagnosis, Saitama Cancer Center Background: Some colorectal cancer (CRC) patients have multiple primary colorectal cancers (MPCRCs) and metachronous CRCs (MCRCs). Aim: We evaluate the current status of MPCRC and MCRC with primary colorectal cancer. This study has examined the proportion of MSI tumors in patients with MPCRC and MCRC compared with primary solitary CRC. Methods: Five hundred and ninety-eight colorectal cancer patients treated between 2000 and 2004 were analyzed. A total of 100 patients with MPCRC and 16 MCRC patients with invasive colorectal cancer were identified. Evaluable tumors were tested for MSI, hypermethylation of the MLH1 promoter and mutation of both KRAS and BRAF. Using a panel of microsatellite markers including mononucleotide and dinucleotide repeats recommended by the National Cancer Institute workshop on MSI, tumors were classified as high level (MSI-H), low level (MSI-L) or stable (MSS). Results: Out of the 598 patients in the study, 218 (36%) had a family history of ABSTRACT BOOK Podium Papers HNPCC-related malignancy, but only one fulfilled the Amsterdam II criteria. Forty of 598 tumors (6. 7%) were MSI-H. Among 100 MPCRCs, gastric cancer was the most common occurrence (47%) followed by prostate cancer (11%) and lung cancer (9%) in the 57 male patients. In the 43 female patients, breast cancer was the most common site (31%) followed by gastric cancer (23%) and cervix cancer (20%). These cancers were commonest diseases in Japan. The frequency of MSI-H was significantly greater in the metachronous CRC, 5 out of 16 (31%) compared with the solitary cancers, 26 out of 482 (5. 4%), P=0. 018. MSI-H was more prevalent in multiple primary CRC, 9/100 (9%) than in solitary cancers (5. 4%), P=0. 168. Patients with MSI-H tumors were in older female predominantly. Germ line mutations of MMR genes (MLH1, MSH2 and MSH6) were confirmed in 13 out of 40 patients (33%) with MSI-H tumor and the methylation of hMLH1 promoter was identified in 19 (48%). Twelve CRCs (30%) with MSI-H showed BRAF V600E mutation. Conclusions: MSI-H is more commonly identified in patients with multiple primary colorectal cancers and metachronous colorectal cancers. S033 SURVEILLANCE OF ANAL CANCER PRECURSOR LESIONS IN HIV POSITIVE AND HIV NEGATIVE PATIENTS, Ricardo A Alfonzp MD, Luis H Angarita MD, Juan C Sierra MD, Hospital de Clinicas Caracas, Caracas, Venezuela Anal cancer affects the squamous epithelium of the anal canal and the perianal skin region. The incidence of anal cancer has increase in the past 30 years. There is evidence that Human Immunodeficiency virus (HIV) positive patients are more likely to present with Human Papiloma Virus (HPV); and patients with HPV are more likely to present with anal cancer. Here we attempt to verify the importance of the surveillance for HPV for the population that visits the colon and rectal clinic at the Hospital de Clinicas Caracas. Materials and Methods: Between 1999 and 2006 we studied 1444 patients that visited our clinic, all patients were screen for HPV with cytology and polymerase chain reaction (PCR) . The population was divided in HIV positive and negative. Each group was subsequently divided according to the cytology results; in Carcinoma, low grade dysplasia, high grade dysplasia. Then both groups were compared. Results: There were 612 patients in the HIV negative group and 832 patients in the HIV positive group. Carcinoma in situ was present in 1. 1% of the HIV negative group and in 3. 7% of the HIV positive group. High grade dysplasia was present in a significant portion of both groups. The HIV positive patients also were positive for HPV in 90% of the cases. The HIV negative patients were positive for HPV in 64% of the cases. These results were confirmed with by PCR. Conclusion: We found that for the population that visits the colon and rectal surgery clinic at the Hospital de Clinicas Caracas there is a very high incidence of HPV in both HIV positive and negative patients. In both groups high grade dysplasia was comparable and HIV positive patients are more likely to present with carcinoma in situ. There for we now routinely screen for HPV all the patients that visit our clinic. S034 WITHDRAWN S035 INTERMEDIATE RESULTS OF A PROSPECTIVE RANDOMIZED STUDY ASSESSING A BRIEF COURSE OF PERIOPERATIVE INTRAVENOUS ANTIMICROBIAL PROPHYLAXIS IN RECTAL CANCER SURGERY, kouki kuwabara MD, Keiichiro Ishibashi MD, Masatsugu Ishii MD, Toru Ishiguro MD, Tomonori Ohsawa MD, Norimichi Okada MD, Masaru Yukoyama MD, Tatsuya Miyazaki MD, Moriyuki Matsuki MD, Hideyuki Ishida MD, Department of Digestive Tract and General Surgery, Saitama Medical Center, Saitama Medical University We report the intermediate results of a prospective randomized study assessing a brief course of intravenous antimicrobial prophylaxis in combination with chemical bowel preparation in rectal cancer surgery. A total of 190 patients who underwent elective surgery for rectal cancer were enrolled, and 181 patients were eligible. All eligible patients were given kanamycin and erythromycin orally after mechanical cleansing, which started within 24 hours of surgery. Those patients were randomized to receive intravenous flomoxef on the day of surgery (Group A, n=87) or for three days (Group B, n=94). The rate of surgical site infection was 12. 6% in Group A and 16. 0% in Group B (p=0. 52). The rate of MRSA infection was 5. 7 % in Group A and 7. www.isucrs.org/ 4% in Group B (p=0. 87). In addition, the leukocyte counts and C-reactive protein levels on postoperative days 1, 4, and 7 did not significantly differ between the groups. These results suggest that use of methods of perioperative antibiotics, according to CDC guideline could be well applied for rectal cancer surgery in Japan. S036 COMPARATIVE ANALYSIS OF PROTECTIVE ILEOSTOMY CLOSURE AFTER INITIAL LAPAROSCOPIC VS. OPEN COLORECTAL SURGERY, Homero Rodriguez MD, Roberto Ramos MD, Sofia Sanchez MD, Omar Vergara MD, Manuel Moreno MD, Hector Tapia MD, David Velazquez PhD, Quintin Gonzalez MD, Instituto Nacional de Ciencias Médicas y Nutrición Salvador Zubirán (INCMNSZ) Introduction: Loop ileostomy is traditionally indicated to avoid anastomotic leakage or dehiscence in colorectal surgery. They are especially indicated in the presence of risk factors such as an anastomosis site less than 5 cm from the anal margin, radiotherapy, bowel obstruction, wound infection or poor surgical expertise Aims: To determine differences regarding surgical time, postoperative complications, hospital stay length and surgical reintervention frequency between patients who underwent loop ileostomy after laparoscopic (LS) or open (OS) colorectal surgery. Methods: 71 medical charts of patients in whom protective loop ileostomy was performed after a primary LS or OS colorectal surgery from 2003 to 2007 at our institution by a single surgical team were reviewed. Data was collected and tabulated for every included patient by one colorectal surgeon . Descriptive and statistical analysis was performed using SPSS 8. 0 according to each variable scaling. Results: Thirty-seven were female (52. 1%) and 34 male (47. 9%). In 43 cases (60. 6%) the primary approach was OS and in 28 (39. 4%) a LS was performed. Gender, age and indications for primary surgery were not statistically different among these two groups (p≥0. 05). As expected, surgical time for ileostomy closure and length of hospital stay were generally shorter in patients with previous LS than OS (p  0. 001). Only patients with OS exhibited reintervention in 6 cases (14. 2%) but none with LS (p=0. 001). Additionally, LS cases showed a decreased complication rate (only 3 patients or 10. 7%) when compared with patients with OS colorectal surgery (13 patients or 30. 2%, p= 0. 003). Conclusions: Our data clearly demonstrates that performing an ileostomy closure after initial LS has several advantages over performing it after an initial OS. We hypothesize that this is due to the intrinsic tissue manipulation which could be considerably less traumatic during LS than OS. This is directly proportional to the presence of postoperative adhesions. An initial LS approach might have impact in the secondary ileostomy closure in terms of surgical time, hospital stay and the incidence of surgical reinterventions or complications. Key Words: Protective ileostomy, laparoscopic colectomy, ileostomy closure. S037 RESULTS OF ILEOSTOMY CLOSURE AFTER RECTAL CANCER RESECTION, Shigeki Yamaguchi PhD, Masatoshi Ishii MD, Jo Tashiro MD, Yoshihide Otani MD, Isamu Koyama, Shuji Saito MD, Masayuki Ishii MD, Department of Gastroenterological Surgery, Saitama Medical University International Medical Center & Shizuoka Cancer Center Purpose: While sphincter saving operation for rectal cancer is increased, patients with diverting stoma are increased, too. Ileostomy is chosen in most of our patients. One of the reasons is easiness of stoma closure. This study was assessed short term results of ileostomy closure. Technique: Suturing and lapping stoma was never performed before skin incision. Dissection from abdominal wall underwent using scissors or bipolar scissors. Until September 2004, single layer hand-sewn anastomosis was performed, and then functional end to end anastomosis (FEEA) using linear stapler was standard method. The reason we changed anastomotic method was functional end to end anastomosis had wider anastomotic diameter and would take less operating time. Results: Ninety patients who received ileostomy closure were included since September 2002 to December 2006. Mean overall operative time (OT) was 63. 3 minutes. Also mean OT was 62. 3 min. in FEEA and 63. 8 min. in hand-sewn anastomosis, respectively. Mean blood loss count was 31 g. Median postoperative hospital stay was 7 days. Postoperative complications were; intestinal 43 ABSTRACT BOOK Podium Papers obstruction 14 (15. 6%), wound infection 2 (2. 8%), and no anastomotic leakage. Intestinal obstruction was seen in 6. 5% (2/31) of FEEA, and 20. 3% (12/59) of hand-sewn anastomosis. Conclusion: Diverting ileostomy is safe because it is easy to close, and less intestinal obstruction was seen in functional end to end anastomosis than in hand-sewn anastomosis. S038 THE EVALUATION OF A FECAL DIVERTING DEVICE AS A SUBSTITUTE FOR A DEFUNCTIONING STOMA: AN ANIMAL STUDY, Jaehwang Kim MD, Sang Hun Jung MD, Daegu, Korea Purpose: The safety of a newly developed fecal diverting device (FDD) that can replace a temporary stoma was confirmed in a preliminary animal study. In this study, we evaluated the positive effect of the FDD in protecting against anastomotic leakage. Methods: This was a randomized prospective study. The FDD is a long, silicon tube with a thick head and a thin tail. Two outer balloons are mounted on the head of the FDD for fixation to the bowel wall. If inflated, the head looks like a dumbbell. An extracolonic mesh band, located 5 cm proximal to the anastomotic area, can hold the head of the FDD. Fecal content proximal to the head of the FDD can be drained out of the anus thorough the tail of the FDD. Twenty mongrel dogs (5 males with a median weight of 19 kg) were divided into 2 groups of 10 each. Under general anesthesia, a low midline incision was made and wide devascularization was enhanced on the colon to generate ischemia at the anastomotic site after resection. A circular stapler was applied to resect and perform the anastomosis. The decision to apply the FDD (Group 1) or not to apply the FDD (Group 2) was made by the flip of a coin. Follow-up observations was recorded until the animal’s death or the FDD was spontaneously expelled in Group 1. The mongrels without a FDD (Group 2) were sacrificed after 3 weeks. At the time of necropsy, we evaluated intraperitoneal findings, the anastomotisis, and the FDD fixed mesh area grossly and microscopically. Results: Mortality occurred in 5 dogs in Group 2. The average survival time of these dogs was 3. 6 days. The cause of death was generalized peritonitis due to anastomotic leakage in all of the dogs. The FDD was spontaneously expelled after an average of 21. 5 days (range, 6-41days) in Group 1. The cause of FDD expulsion was most often spontaneous deflation of the dumbbell-shaped outer balloons. In the necropsy findings, a sealed off abscess cavity was noted in 4 dogs in Group 1 and 2 dogs in 5 survived mongrels in Group 2. Erosion of the mesh band was noted in 2 dogs in Group 1. Conclusions: A newly developed fecal diverting device was shown to be safe and effective in the protection against generalized peritonitis from anastomotic leakage due to induced ischemia. The fecal diverting device was maintained in situ and functioned for more than 3 weeks in the animal colon without any major complications, except two erosions. COLORECTAL CANCER AND FUNCTIONAL DISEASE I S039 CLINICAL APPLICATION OF IN-VITRO CHEMOSENSITIVITY TEST FOR COLORECTAL CANCER USING MTT ASSAY IN KOREA, Seong-soo Kim MD, Byuongwook Min PhD, Jun-won Um PhD, Hong-young Moon PhD, Department of Surgery, Korea university College of Medicine, Seoul, Korea Background: In colorectal cancer, surgical treatment is fundamental but pre or postoperative chemotherapy and radiotherapy are widely accepted and many chemotherapic agent is available. In Korea, 5-FU, oxaliplatin and irinotecan are most widely used but these agent are applied to the each TNM stage because of the restriction in medical insurance system. Purpose: The MTT chemotherapy response assay is a well-documented and feasible technology for individualizing chemotherapy in cancer patients. We evaluate the assay’s success rate and the suitability of chemotherapeutic agent according to assay result. Method: Tumor samples were collected from 124 patient. In 108 patients, cultures were succed. Tumor specimens were cultured for 7 days on collagen gel sponge in RPMI medium with chemotherapeutic agents. Then the inhibitory concentration was determined by MTT assay. The result was also confirmed by immunohistochemistry for Ki-67, P53, and BCL-2. (Results) The assay success rate was 44 ISUCRS XXII BIENNIAL CONGRESS 87. 1%(108/124). The mean age of the patients was 62. 9 years, and the male-to-female ratio was 1. 1:1. l. The sites of cancer were ascending colon 21(20. 5%), transverse colon 2(1. 7%), Descending colon 6(5. 4%), sigmoid colon 27(25%), and rectum 50(48. 2%). According to TNM stage, there were 12 cases of stage I, 45 cases of stage II, 35 cases of stage III, and 16 cases of stage IV. In case of differentiation, moderate differentiation was most frequent (88 case, 81. 5%). Among the 108 cases, the positive chemosensitivity cases to 5-FU, oxaliplatin, irinotecan were 56, 49, and 44 respectively. The number of patients received chemotherapy was 88, but appropriate chemotherapy to chemosensitivity result was 25/48 in 5-FU regimen, 9/30 in FOLFOX4 regimen, and 6/10 in FOLFIRI regimen. Conclusion: A study evaluating the predictive value of MTT drected therapy is needed to determine the clinical usefulness of the test. S040 ULTRALOW ANTERIOR RESECTION AND HANDSAWN COLOANAL ANASTOMOSIS: ONCOLOGIC AND FUNCTIONAL OUTCOMES, Byung Soh Min MD, Hyuk Hur MD, Jin Soo Kim MD, Seung Kook Sohn PhD, Chang Hwan Cho MD, Seung Hyuk Baik MD, Nam Kyu Kim PhD, Yonsei University Health System, Seoul, Korea Background: Ultralow anterior resection and hand-sawn coloanal anastomosis has been a standard surgical treatment for low rectal cancer. Despite many published results, there are few concerning Asian populations. The aim of this study was to investigate oncologic and functional outcomes of ultralow anterior resection and hand-sawn coloanal anastomosis for the treatment of rectal cancer and to analyze clinicopathological factors affecting the outcomes. Patints and Methods: From a prospective colorectal cancer surgical database, 134 patients who received ultralow anterior resection and hand-sawn coloanal anastomosis for the treatment of rectal cancer were identified and their clinicopathological features were reviewed. For evaluating functional outcomes, Wexner score and BM frequency were analyzed. Results: The mean age of the patients was 54. 7 years. Forty-two patients (32. 1%) received preoperative chemoradiation, whereas 57 (42. 5%) received postoperative chemoradiation and 35 (25. 4%) received neither. Colonic J-pouch anal anastomosis was performed in 95 patients (70. 9%) and straight in 39 (29. 1%). Postoperative morbidity was in 23 patients (16. 4%), voiding difficulty being the most frequent (6. 0%) followed by intestinal obstruction (5. 2%), and anastomosis leakage (3. 0%). Three-year disease-free survival rate according to stage was 100% for stage 0, 96. 3% for stage I, 89. 3% for stage II, and 57. 4% for stage III (p<0. 001). uni- and multivariate analyses revealed that T3/4 tumors (OR=6. 773; P=0. 010), < 40 years (OR=4. 352; P=0. 015), < Anal Verge 5cm (OR=2. 656; P=0. 024), and N(+) (OR=3. 541; P=0. 048) were significant prognostic factors. Wexner score and BM frequency were observed to decrease 3 years after the surgery. Within 6 months after surgery, BM was more frequent when the patient had received preoperative chemoradiation (p=0. 048) and straight anastomosis (p=0. 042). Conclusion: Ultralow anterior resection and hand-sawn coloanal anastomosis for the treatment of rectal cancer showed acceptable range of postoperative morbidity and satisfactory oncologic and functional outcomes. Early functional impairment is more severe in the patient who received preoperative chemoradiation and straight anastomosis, but it may improve after 3 years. S041 VOIDING & SEXUAL DYSFUNCTION AFTER RADICAL EXCISION OF THE RECTUM, Galal M AbouElnagah MD, Ahmed Hussin MD, Colorectal surgical Unuit, Alexandria University, Egypt Introduction: Bladder and erectile dysfunction are well recognized after radical excision for patients with operable cancer rectum. Reported rates varies from 10% to 60%. Most common complains are urgency, retention, neurogenic bladder, impotance and retrograde ejaculation. Method: Prospective study were conducted on 50 consecutive operable cancer rectum patients. All underwent abdominoperineal radical excision of the rectum. Urodynamics studies were done before, one month and three months after operation, it include: spontaneous flowmetry, residual urine, cystometry, detrusor pressure, urinary flow and urethral pressure profile. Results: 31 men and 19 women, ABSTRACT BOOK Podium Papers mean age 43. 2. Twenty patients were having urinary complains Preoperatively, in the form of hesitancy, frequency, dysurea and nocturnal frequency. Post operatively only 8 patients still had it; 6 temporary, one benign prostatic hyperplasia and one neurogenic bladder. Duke’s Staging of excised tumours were: 54% B, 40% C, 6% D. There were no statistical differences between preoperative and postoperative urodynamic studies. Gender, learning curve, and depth of tumor exerted an independent influence on urinary or sexual dysfunction. Conclusion: Voiding disturbances following rectal surgery are usually transit, sexual dysfunction is difficult to be determined and compared. It is not essential to apply preoperative urodynamic study in non symptomatic cancer rectum patients. Postoperative urodynamic studies are useful in symptomatic patient only after a period of conservative trial. Most of pre operative urinary complains are due reflex effect of tumor anorectal manifestation on urinary tract. These are usually improved after rectal excision specially with large size tumors. S042 DEFECATORY DISORDER DUE TO DENERVATION/ MOTILITY DISORDER OF THE NEORECTUM FOLLOWING ANTERIOR RESECTION FOR RECTAL CANCER, K Koda MD, H Yasuda MD, M Yamazaki MD, T Tezuka MD, C Kosugi MD, R Higuchi MD, M Sugimoto MD, Y Yagawa MD, Department of Surgery, Teikyo University Chiba Medical Center Introduction: Healthy rectum and sigmoid colon were double innervated with ascending fibers from the pelvic plexus and descending fibers that run along the internal mesenteric artery (IMA). Therefore, the neorectum in anterior resection for rectal cancer is constructed using a denervated colonic segment of a length that varies from case to case. We evaluated the motility of the neorectum which may potentially be associated with postoperative defecatory disorders. Patients and Methods: Eighty-two patients (48 men and 34 women; median age, 61) who underwent anterior resection for rectal cancer were enrolled in the present study. There were 21 ultra-low anterior resections, 46 low anterior resections, and 15 high anterior resections included. Reconstruction methods were a colonic J-pouch (n=12), a sideto-end anastomosis (n=12), and an end-to-end anastomosis (n=58). The interval between initial surgery and the time when the physiological study was carried out was 1 year in 46 cases (56%) and more than 2 years in 36 cases (44%). Colonic motility was measured using a specially manufactured pressure transducer that consisted of 4 sensors 20cm apart inserted at the time of the postoperative colonoscopy. Colonic transit time was determined using Sitzmarks capsules, which consisted of 20 radiopaque markers within a gelatin capsule. Postoperative defecatory functions were evaluated with a self-administered questionnaire. Results: Of 82 patients, both IMA and descending nerve fiber were preserved in 30 cases that were categorized in gshort denervation (S) grouph, since the neorectum of these patients are thought to be composed of short denervated colonic segments. In the remaining 52 cases, either IMA were cut (n=36) or in case IMA was preserved, the surrounding tissue was removed for lymph node dissection (n=16); they were categorized in glong denervation (L) grouph. Propagation of contraction wave to neorectum was observed in 25/30 cases for S-group, whereas 27/52 cases in L-group showed propagations (p=0. 005). Spastic contractions of neorectum were observed in 7/30 for S-group, 25/52 for L-group (p=0. 035). In patients to whom low/ ultra low anterior resection was performed (n=67), colonic transit time trough sigmoid colon/ rectum was significantly longer in L-group than in S-group (5. 9 vs. 3. 3 hrs, p=0. 03). In these patients, there was a tendency that both urgency and Wexner’s score are better in S-group than in L-group, however they did not reach statistical significance (p=0. 17, 0. 14, respectively). Conclusion: The glongh denervated neorectum may cause motility disorders in the neorectum following anterior resection for rectal cancer. Denervation to the neorectum may be one possible factor that indirectly relates with postoperative function. S043 ROLE OF SACRAL NERVE STIMULATION(SNS) IN CHRONIC CONSTIPATION, N Srinivasaiah MD, P W Waudby RN, G S Duthie MD, 1. Academic Surgical Unit, University of Hull, Cottingham, UK Introduction: Chronic constipation can be extremely difficult to treat affecting one’s QOL. SNS has been tried when other www.isucrs.org/ treatments have failed. However, reports of this procedure are limited, so we reviewed our experience in order to determine whether it is a worthwhile procedure. Methods: Patients who underwent SNS for chronic constipation were identified (Aug 2005 - Oct 2007). This is a retrospective review of a prospectively maintained SNS database and the notes reviewed. Results: There were 12 patients with chronic constipation who were referred to be considered for SNS. The mean age was 39 years. All the patients were females. Under the category of constipation were also included 3(25%)patients who had constipation with overflow incontinence following laxatives and bowel movement. Majority of them were idiopathic slow transit constipation, with 2(16%) of them secondary to spinal traumatic neuropathy. Nearly 1/3rd of the patients complained of abdominal discomfort, pain, bloating, lack of motivation, embarrassment and depression impacting on their QOL and making them socially isolated. The average frequency of bowel movements were 3-5 /month assisted with enormous amounts of laxatives, bulking agents, suppositories, enemas, biofeedback, rectal irrigation and ante grade continent enema. Out of the 12 patients who were referred for SNS, there were 9 (75%) temporary and 6 (50%) permanent SNS procedures performed. 3 (25%) of them are awaiting a temporary SNS procedure. All the 6 (50%) who had permanent SNS procedures have had success. There was failure in 1(8%) following 2 temporary SNS procedures, refusal in 1(8%) without trial SNS and return to normal bowel habit in 1(8%) after a failed temporary SNS. Assessment of the bowel diaries among successful patients, showed an improvement in bowel movements to once/day - 3 times/week. They also demonstrated improvement in abdominal symptoms and QOL. One (8%) patient had pain on urination following the SNS procedure who had her settings changed and is awaiting to be reviewed. Conclusions: We would conclude that SNS for chronic constipation in our experience offers an option, when other treatments have failed. COLORECTAL CANCER AND FUNCTIONAL DISEASE II S044 URINE N1N12-DI-ACETYL SPERMINE (DIACSPM) AS A NOVEL CANCER MARKER FOR COLORECTAL CANCER, Keiichi Takahashi MD, Kyoko Hiramatsu PhD, Tatsuro Yamaguchi MD, Hiroshi Matsumoto MD, Daisuke Nakano MD, Youzou Suzuki MD, Takeo Mori MD, Masao Kawakita PhD, Department of Surgery, Tokyo Metropolitan Komagome Hospital Backgrounds: For colorectal cancer screening fecal-occult blood test (FOBT) is the standard screening test all over the world. But the positive predict value (PPV) in colorectal cancer is about 60%. Fecal DNA analysis is too expensive and is difficult to use colorectal cancer screening in clinical practice. It is necessary to combine another non-invasive new test with FOBT to improve the PPV. In this paper we clarified the possibility to use urine N1N12-di-acetyl spermine (DiAcSpm) for colorectal cancer screening. Methods: DiAcSpm increases for several kinds of cancer. We succeeded the quantity of DiAcSpm by ELISA method. In this paper we examined urine DiAcSpm(normal range : 0~0. 25 ƒÊmol/gEcreatinine) and serum CEA(normal range : 0~5. 0ng/ml) for 243 colorectal cancer patients preoperatively and urine DiAcSpm for 53 normal controls. Results: Only 2 persons (3. 7%) were positive for normal controls in urine DiAcSpm. Positive rate of each stage in 243 cases was as followsGstage I (N=36) F 47. 2% for urine DiAcSpm and 11. 1% for serum CEA respectively, stage II (N=60) F68. 3% and 51. 7%, stage III(N=102) F81. 4% and 43. 1%, stage IV(N=45) F93. 3” and 82. 2%. In proportion to staging, the positive rates for both markers became high. Especially urine DiAcSpm level for stage I colorectal cancer showed statistically significant higher than serum CEA (p<0. 0001). The results of statistical analysis of urine DiAcSpm for colorectal cancer were 75. 3% for sensitivity, 96. 2% for specificity, 98. 9% for PPV and 45. 9% for negative predictive value. Conclusions: The positive rate of Urine DiAcSpm was higher than that of serum CEA for colorectal cancer, especially for early staged patients. It suggested that the combination of FOBT and urine DiAcSpm realized the improvement of colorectal cancer screening. 45 ABSTRACT BOOK Podium Papers S045 IMPACT OF RADIOTHERAPY ON COMPLICATIONS AND SPHINCTER PRESERVATION AFTER COLOANAL ANASTOMOSIS FOR DISTAL RECTAL CANCER, Hyuk Hur MD, Byung Soh Min, Jin Soo Kim MD, Nam Kyu Kim MD, Seung Kook Sohn MD, Chang Hwan Cho MD, Yonsei University College of Medicine, Department of Surgery Introduction: Coloanal anastomosis(CAA) has improved the rate of sphincter preservation for rectal cancer. But, radiotherapy(XRT) occasionally produce complications and result in failure of sphincter preservation and formation of permanent colostomy. The aim of this study was to assess the impact of radiotherapy on complications and colostomy-free survival of patients after CAA. Materials and Methods: A total of 107 patients underwent CAA between 1999 and 2006: 70 patients received XRT(28 preoperative(Group I) and 42 postoperative(Group II)); 37 patients did not receive XRT(Group III). Complications and the colostomyfree survival rate were assessed by retrospective review of patients records. Results: The most frequent complication was an anastomotic stricture with others(fecal incontinence, fistulas, anastomotic leakage, abscesses, and bowel obstruction). Patients receiving XRT had a higher rate of complications compared with patients not receiving XRT; Group I(10/28, 35. 7%), Group II(15/42, 35. 7%), Group III(7/37, 18. 9%). 14 patients required permanent colostomy(Group I: 4/28(14. 3%), Group II: 8/42(19%), Group III: 2/37(5. 4%)). 10 patients required colostomy because of anorectal dysfunction (incontinence, stricture, fistula, leakage or abscess); 1 patients because of bowel obstruction; 3 patients because of local or systemic recurrence. Patients receiving XRT(Group I and Group II) had a lower 5-year colostomy-free survival rate compared with patients not receiving XRT(Group III)(71. 6% vs. 93. 2, P=0. 034). Conclusion: Althouth CAA was performed for sphincter preservation for rectal cancer, preoperative or postoperative XRT may increase the incidence of complications and the need for a permanent colostomy. S046 THE IMPACT OF ANORECTAL ELETROMANOMETRY IN 163 CONSECUTIVE PATIENTS EVALUATED IN A COLORECTAL PHYSIOLOGY LABORATORY, José Paulo T Moreira MD, Hélio Moreira Jr MD, Hélio Moreira PhD, Geanna R Guerra MD, Arminda C Almeida MD, Coloproctology Service, Federal University of Goiás, Brazil Introduction: In the past 20 years we have seen an increasing availability of anorectal physiologic tests among colorectal surgeons. Anal eletromanometry (EMN) is the most used by physicians in Brazil. Aim: Evaluate the results of EMN and its impact on decision making in patients with anorectal diseases. Method: 163 consecutive patients were evaluated by EMN at the Physiology lab of Coloproctology Service at the Federal University of Goiás, between nov/2006 and sept/2007. Results: 163 consecutive patients were analyzed, with median age of 40 (range, 2-87 years). Clinical symptoms of the patients that indicated EMN were: fecal incontinence (n=40), chronic anal fissure (n=23), constipation (n=77), others (n=23). Patients with fecal incontinence presented with median resting and squeeze pressure of 43 mmHg and 108 mmHg, respectively. Meanwhile, 45% of the patients had low resting pressures. Rectal sensitivity was abnormal in 70% of the patients and in half of the cases, rectal capacity was below the expected values. Forty seven out of 77 constipated patients had positive serology for Chagas´ disease, despite of no radiological megacolon. Moreover, a positive inhibitory anorectal reflex (IARR) 46 ISUCRS XXII BIENNIAL CONGRESS was observed in 15 cases (32, 5%), excluding the possibility of Chagas´ colopathy. Ten children from the constipated group were evaluated for the possibility of congenital megacolon. The IARR was present in all cases, excluding Hirschsprung´s disease. For the remaining patients with constipation, the median resting pressures was 62 mmHg and squeeze pressure 120 mmHg, with positive IARR in all of them. In the chronic anal fissure group, the resting and squeeze pressures were above normality in 47, 8% and 43, 4% of the patients, respectively. Conclusion: In the assessment of the incontinent patients, the EMN was important to graduate the severity of sphincter tone as well to identify possible muscular injuries. In the constipated group, the EMN was very useful in the subgroup of positive serology for Chagas´ disease, with no radiological megacolon as well to exclude congenital megacolon in children. In patients with chronic anal fissure, this test was important as an objective method for evaluating patients who really have elevated anal canal pressures. Therefore, EMN provided useful information in 70% of the evaluated patients. S047 NON-STIMULATED GRACILOPLASTY - WILL IT BECAME THE METHOD OF CHOICE?, Roman Herman PhD, Piotr Walega PhD, Anna Gierada MD, 3rd Department of Surgery, Cracow Objective: Graciloplasty is a well-established surgical treatment method of feacal incontinence (FI). Because of the complexity of this procedure it is reserved for patients with end-stage fecal incontinence. We aimed at comparison between standard dynamic graciloplasty and non-stimulated graciloplasty. Patients: Seventeen patients (11 women, 6 men) with end stage fecal incontinence due to sphincter injuries (13) and congenital absence (4) underwent graciloplasty (GP) between 2000 and 2007 in 3rd Department of Surgery of Jagiellonian University School of Medicine. Method: The procedures were made following the method proposed by Pickrell-Baeten with /split-sling/ modification proposed Cavina-Rosen with intraoperative anal manometry to archive optimum tension of the muscle. Following examinations were made in all cases before and 6, 12 and 24 months after surgery: surface electromyography, anal manometry, Feacal Incontinence QoL and assessment of severity of incontinence using Fecal Incontinence Severity Index (FISI); electrically stimulated muscle transformation procedure was conducted on 5 patients, in 12 cases procedure of non stimulated GP was performed with subsequent transanal electro-stimulation. Results: In all patients significant improvement of defecation self-control was observed, with parallel life quality and overall psychosocial functioning improvement. No statistically significant differences in life quality between patients with DGP and non-stimulated GP were observed. Conclusion: End-stage fecal incontinence treatment effects can be considered as satisfactory in both groups. Non stimulated graciloplasty seems to be recommendable technique for end-stage fecal incontinence due to significantly lower costs and avoidance of stimulator related complications and similar functional results. S048 ROLE OF SACRAL NERVE STIMULATION (SNS) IN CHRONIC PELVIC PAIN (CPP), N Srinivasaiah MD, Phillip Waudby RN, B Culbert, G S Duthie MD, 1. Academic surgical unit, Castle Hill Hospital, University of Hull, Cottingham, UK. 2. Department of Anaesthetics, Castle Hill Hospital, Cottingham, UK Introduction: Sacral nerve stimulation has revolutioned the treatment of various pelvic floor disorders. The remit of its use has been increasing to include a number of pelvic disorders. Chronic pelvic pain (CPP) is a disorder which can be extremely difficult to treat affecting one’s QOL. SNS has been tried in the treatment of CPP when other treatments have failed. The reports of this procedure for CPP are limited, so we reviewed our experience in order to determine whether it is a worthwhile procedure. Methods: Patients who underwent SNS for chronic pelvic pain were identified (Aug 2005 - Oct 2007). This is a retrospective review of a prospectively maintained SNS database and the notes reviewed. Results: There were 7 patients who received SNS for chronic pelvic pain. The mean age was 50 years. Female to male ratio was 6:1. Referrals were from the pain clinic, followed by gynaecology. Under the broad category of pelvic pain were rectal and upper anal canal pain, Ischial tuberosity and coccygeal pain, rectal spasms, Buttock pains, Vulvodynia and Non specific pelvic pain. ABSTRACT BOOK Podium Papers Three of them attributed their problem to an injury sustained either by trauma or pelvic surgery. More than half of them had other associated pelvic problems like rectocele, cystocele, uterine prolapse, irritable bladder and abnormal pelvic anatomy. Two patients had low resting squeeze pressures and pudendal nerve dysfunction on Endo-anal ultrasound and neurophysiology. Failed treatments included analgesics, antispasmodics, antiepileptics, antidepressants, botox injections, TENS and caudal blocks. In total 11 temporary SNS devices were used. 2 (28. 5%) patients had successful outcome and five failed. Among the successful ones PACS / BPI assessment showed an improvement of 70% 80 % at the end of two weeks of temporary test stimulation. The successful ones are waiting for a permanent SNS to be implanted. Among those who had failed SNS, worsening pelvic pain was seen in two of them. Conclusions: We would conclude that SNS for chronic pelvic pain with our limited experience offers an option, when other treatments have failed. However, the success rates one could achieve might be less. MIXED PLENARY SCIENTIFIC SESSION S049 LAPAROSCOPIC VS. OPEN TOTAL MESORECTAL EXCISION, Quintin Gonzalez MD, Homero Rodriguez MD, Jose Moreno MD, Omar Vergara MD, Hector Tapia MD, Roberto Ramos MD, Roberto Castañeda MD, Instituto Nacional de Ciencias Medicas y Nutrición “Dr. Salvador Zubirán”. Mexico City Background: Laparoscopic total mesorectal excision (LTME) for rectal cancer has been proposed to have several short-term advantages in comparison with open total mesorectal excision (OTME). However, few prospective randomized studies have been performed. Objectives: The main purpose was to evaluate whether relevant differences in safety and efficacy exist after elective LTME for the treatment of rectal cancer compared with OTME in a tertiary academic medical center. Methods: This comparative nonrandomized prospective study analyzes data in 56 patients with middle and lower rectal cancer treated with LAR or APR from November 2005 to November 2007. Descriptive and statistical analysis was performed using SPSS 8. 0 according to each variable scaling. Statistical significance was considered whenever a p value was equal or less than 0. 05 for a two-tailed distribution. Results: 28 patients underwent LTME and 28 patients underwent OTME. The mean operative times for LTME and OTME procedures were 181. 3 min and 206. 1 min p<0. 002. The mean operative blood loss was 139. 2 ml and 231. 8 p<0. 003. There was a significant difference in time to reinstitute oral intake in the LTME (2) versus OTME (3) p< 0. 05. Postoperative hospital stay was shorter in the LTME group (5. 5 days) versus the OTME group (7. 9 days) p< 0. 04. A significant difference in terms of recovered lymph nodes was found in the LTME (12. 1 +-2) versus OTME (9. 3+-3) p< 0. 05. There was no 30-day mortality. Morbidity was lower in the LTME group compared to the control group (17% vs 32%). Return of bowel motility was observed earlier after laparoscopic surgery. Mean follow-up time was 12 months (range 9-24 months). No local recurrence was found. Conclusion: LTME is a feasible procedure with acceptable postoperative morbidity and low mortality, however it is technically demanding. This series confirms its safety, while oncologic results are at present comparable to the OTME published series with the limitation of a short follow-up period. Key words: Laparoscopy rectal cancer- Total Mesorectal Excision. S050 CLEVELAND CLINIC FLORIDA RECTAL CANCER EXPERIENCE, B Santoni MD, P Denoya MD, E Stone MD, D Sands MD, J Nogueras MD, E Weiss MD, S Wexner MD, Cleveland Clinic Florida Objective: The aim of the study was to evaluate the effects of neoadjuvant chemoradiotherapy on downstaging and short-term surgical complications. Method: After IRB approval, patients with a diagnosis of rectal cancer who underwent surgery between January 2001 and October 2007 were identified from prospectively collected databases. Charts with incomplete or missing pre- and postoperative staging were excluded. Age, comorbidities, pre- and post-operative staging, pos-operatory complications and hospital stay were all examined. Result: 87 patients were identified, www.isucrs.org/ 49 of whom received neoadjuvant chemoradiation therapy. The median age was 63, ranging from 29 to 93 years, and the operations performed included abdominoperineal resection (18), anterior resection (42), transanal excision (14), sigmoid resection (1) and proctocolectomy(12). 23 patients received a colonic J-pouch reconstruction, and 19 patients had a diverting ileostomy. Postoperative ileus was experienced by 20% of patients who received neoadjuvant therapy and by 5% of those who did not receive neoadjuvant therapy (p=0. 03). 18% of the neoadjuvant group and 5% of the non-neoadjuvant group had medical complications (p=0. 06). Frequency of wound and surgical complications was similar in both groups. The average length of stay was 13. 8 days for the neoadjuvant group, and 6. 7 days for the non-neoadjuvant group (p=0. 07). In subgroup analysis of the 62 patients for whom preoperative and postoperative staging data were available, 54% were downstaged after neoadjuvant therapy (p=0. 01). Conclusion: Neoadjuvant chemoradiotherapy was significantly associated with postoperative ileus resulting in longer hospitalizations and increased postoperative morbidity. The pathology in over half of the patients who received neoadjuvant therapy showed downstaging. In select patients the adverse effects of neoadjuvant therapy may be outweighed by the benefits. S051 DIAGNOSTIC ACCURACY OF PREOPERATIVE AND FOLLOW-UP PET/CT IMAGING FOR COLORECTAL CANCER, Yoshiko Bamba MD, Michio Itabashi MD, Yusuke Tada MD, Tomoichiro Hirosawa MD, Shimpei Ogawa MD, Akiyoshi Seshimo MD, Shingo Kameoka MD, Department of Surgery II, Tokyo Women’s Medical University, School of Medicine, Tokyo, Japan Purpose: We studied the diagnostic accuracy of preoperative and follow-up PET/CT imaging for colorectal cancer. Materials and Methods: Two hundred nine preoperative patients and 94 follow-up patients were examined by PET/CT. The results demonstrated the accuracy of clinical diagnosis, including diagnosis of metastasis to other organs. Results: Preoperative examination The main colorectal tumor was detected in 195 cases (93. 1%) by PET/CT. All tumors not detected in PET/CT were less than 25 mm in diameter. To detect paracolic lymph nodes, sensitivity was 25. 0%, specificity was 91. 7%, and positive predict value (PPV) was 58. 3%. For mesocolic lymph nodes, sensitivity, specificity and PPV were 100%. The average diameter of lymph nodes detected by PET was 11. 3 mm. On the other hand, that of nodes that were not detected was 5. 63 mm. Liver metastasis was detected in 22 cases, with sensitivity of 100% and PPV of 95%. Peritonitis carcinomatosa was detected in 10 cases, representing sensitivity of 50% and PPV of 100%. Follow-up examination Ninety cases were examined for recurrence or by whole-body assessment. Twenty-eight cases were examined after radiation therapy or chemotherapy. Liver metastasis was detected in 30 cases, with sensitivity of 96. 7%, specificity of 100% and PPV of 100%. Lung metastasis was detected in 23 cases, with sensitivity of 43. 5%, specificity of 100% and PPV of 100%. The average diameter of the lung metastases detected by PET was 14. 8 mm, while that of lesions that were not detected by PET was 10. 6 mm. Local metastasis was detected in 14 cases, with sensitivity, specificity and PPV of 100% for all. Peritonitis carcinomatosa was detected in 10 cases, with sensitivity of 70%, specificity of 100% and PPV of 100%. Conclusions: Preoperative and follow-up PET/CT imaging for colorectal cancer is very useful for detecting metastasis or recurrence. COLORECTAL CANCER AND COLORECTAL EMERGENCIES S052 MICROSATELLITE INSTABILITY AND 18Q ALLELIC IMBALANCE IN YOUNG PATIENTS WITH COLORECTAL CANCER, Akifumi Kuwabara MD, Takeyasu Suda MD, Haruhiko Okamoto MD, C. Richard Boland MD, Katsuyoshi Hatakeyama MD, Digestive and General Surgery, Niigata Graduateschool Medical and Dental Sciences Background: Colorectal cancer (CRC) can be classified according to genetic instability selectively affecting microsatellite DNA sequences (microsatellite instability, or MSI) or the chromosome number and structure (chromosomal instability, characterized by 47 ABSTRACT BOOK Podium Papers aneuploidy and loss of heterozygosity or LOH). The relationships between MSI and LOH, and the clinicopathological significance of MSI and LOH in young patients with CRC, are unclear. Methods: The clinical records of all patients 40 years of age or younger admitted to the Niigata Univ. Hospital between 1972 and 1992 for CRC were reviewed. The original pathological specimen could be retrieved on 49 of these patients, which served as the study population. A panel of 5 markers recommended at the Bethesda conference was used to detect MSI. Six additional markers (D18S64, D18S69, p53MEL, TGF ƒ ÀRII(A)10, IGFIIR(G)8, BAX(G)8) were used to examine both LOH and the MSI status. Results: The patients were 13 to 40 years old (median age: 36 y. o. ; average: 34. 9 y. o. ). MSI (i. e. , 2 or more microsatellites were mutated) was found in 15 (31%) of 49 tumors, and frameshift mutations of the TGF ƒ ÀRII gene were detected in 11 (73%) of these 15 tumors. LOH at one or more loci was found in 27 (55%) of the tumors. The MSI genotype was associated with a better prognosis than the LOH genotype, but the difference was not statistically significant. Three (6%) tumors showed overlap between MSI and LOH, and the patients’ Esurvival curve was similar to that of the LOH group. Ten tumors (20%) demonstrated neither MSI nor LOH, as assessed by the 11 markers, and the survival curve of the patients was similar to that of the MSI group. The five-year survival rate for patients bearing the TGF ƒ ÀRII(A)10 frameshift mutation was 91%, as compared to 52% for patients with only wild type alleles (p<0. 04). The five-year survival rate of patients who retained the 18q allelic markers was 71%, as compared to 36% of those showing loss of the 18q alleles (p<0. 03). Four patients only in the MSI group had metachronous CRCs and primary cancers at other organs after postoperative 5 years. The rate of cancers in a first degree relative (67%) was significantly higher in the MSI group. Conclusions: Retention of 18q alleles and microsatellite shifts of the TGF ƒ ÀRII(A)10 gene were associated with a significantly better outcome in young patients with CRC. Analysis of MSI and LOH would suggest the useful information for the postoperative surveillance. S053 SCREENING FOR HEREDITARY COLORECTAL CANCER IN CHINA, Shu ZHENG MD, Yanqin HUANG MD, Ying YUAN PhD, Shanrong CAI PhD, Suzhan ZHANG PhD, Cancer Institute (The Key Laboratory of Cancer Prevention and Intervention, China National Ministry of Education), the 2nd Affiliated Hospital, Zhejiang University PART 1: Detecting hMSH2/hMLH1 mutation in clinically diagnosed Chinese HNPCC Objective: To identify germline mutations of hMLH1 and hMSH2 in HNPCC kindred fulfilling Chinese HNPCC criteria. Method: 14 HNPCC fulfilling Chinese HNPCC criteria probands and 14 kindreds peripheral blood DNA samples were obtained. PCR amplified 35 exons of two main MMR (hMLH1 and hMSH2). DHPLC followed by DNA sequencing was used to detect and confirm mutations. Multiplex RT-PCR was used to detect large genomic rearrangement of hMSH2/hMLH1. Result: 12 single nucleotide changes were identified in 14 probands. Among them, 3 were germline pathological mutations. One of the 14 probands was found with deletion of hMSH2 exon 1-7. 5/7-6/7 relatives of mutation carriers carried the same mutation. Conclusion: Valid mutations of hMLH1 and hMSH2 genes were identified in onethird HNPCC kindreds fulfilling Chinese HNPCC criteria. Incidence of mutation carriers is more than 1/2. PART 2: Comparing the MSI Subtype Cancers between Colorectal Cancer and Gastric Cancer in Chinese Population. Objective: The purpose of this study is to discover clinic-pathological features as well as the genetic and epigenetic causes of both MSI-H CRC and MSI-H GC in Chinese population. Method: A total of 303 CRC and 288 GC unselected patients were involved in this study. Instability of both BAT25 and BAT26 were used to define MSI-H tumor. Mutation of hMSH2/hMLH1 and methylation of hMLH1 promoter region were detected in every MSI-H tumors. Result: MSI-H CRC and MSI-H GC account for 10. 2% and 6. 6% of unselected CRC and GC patients respectively. Genetic and epigenetic analysis resulted in 6/31 MSI-H CRC & 0/19 MSI-H GC with pathological mutation and 6/31 MSI-H CRC & 15/19 MSI-H GC with methylated hMLH1 promoter. Conclusion: most of MSI-H GC in Chinese population is mainly caused by methylation of hMLH1. But neither methylation nor somatic mutation is main cause of MSI-H CRC. Clinic-pathological 48 ISUCRS XXII BIENNIAL CONGRESS features of MSI-H GC is relatively indefinite. PART 3: FAP clinic phenotype¡ªCHRPE as a screening FAP case/carrier ¡®marker¡¯ from the kindreds. Total 33 FAP family resources were collected including 26 CFAP, 4AFAP and 3 SAFAP families, the CHRPE were found in 90. 91% families¡¯ kindreds. The appearance of CHRPE was more frequent in CFAP (94. 12) compared to that AFAP (66. 67%). With the CHRPE a screening model was set up. Its sensitivity and specificity to both FAP and mutation gene carrier were 91. 84% and 100% respectively. S054 GASTROINTESTINAL MALIGNANCY AND PREGNANCY, YW Yun MD, JY Kim MD, HK Chun MD, HR Yun MD, YB Cho MD, HC 1 Kim MD, SH Yun MD, WY Lee MD, WY Chang MD, Department of Surgery, Samsung Medical Center, Sungkyunkwan University School of Medicine, Seoul, Korea, Department of Surgery, Cheju University, Cheju, Korea Colorectal cancer during pregnancy is rare, with a reported incidence of approximately 0. 002%. The frequency of gastric cancer during pregnancy seems to be higher than colorectal cancer and has been reported as 0. 026% in Japan. Recently, we experienced six cases of colorectal cancer and three cases of gastric cancer during pregnancy. The chief complaints were various gastrointestinal symtoms, such as abdominal pain, discomfort, hematochezia, vomiting, melena, and so on. Delayed diagnosis was common, because of the similarity beween the sign of gastrointestinal cancer and the symptoms relevant to pregnancy. The diagnosis of cancer was confirmed by endoscopic biopsy. When these cancers were diagnosed during the first half of pregnancy, cancer surgery was performed promptly, without disturbing the pregnancy when possible. With diagnosis later in pregnancy, consideration was given to delaying treatment until the infant is viable, proceeding with radical surgery after cesarean or induced vaginal delivery. Six cases with colorectal cancer and two cases with gastric cancer received curative operation, while one case with gastric cancer received palliative operation. Although the duration of follow-up is different among cases, all six cases with colorectal cancer have been alive. One case with gastric cancer has been alive for 34 months, and another case was followed until 29 months postoperatively. Another one case who received palliative operation died at three months postoperatively. S055 THE PROGNOSIS FOR ADVANCED RECTAL CANCER UNDERWENT PREOPERATIVE CHEMORADIOTHERAPY, SH JUNG MD, HJ KIM MD, JS KIM MD, JH KIM MD, JH KIM MD, MC SHIM, Department of Surgery, College of Medicine, Yeungnam University, Daegu, Korea Purpose: Although the advent of rectal cancer treatment, its prognosis is very widely. Radical surgery is cornerstone for rectal cancer treatment. Multiple randomized trials have established the role of neoadjuvant and adjuvant radiotherapy and chemotherapy in advanced rectal cancer. The purpose of this study is to identify clinical and pathological prognostic factors and recurrence pattern for advanced rectal cancer underwent preoperative chemoradiotherapy following abdominal radical lymphadenectomy. Patients and Methods: Between 1995 and 2004, 189 patients with rectal cancer located within 12 cm from the anal verge were enrolled finally. Preoperative staging was performed by rectal examination, abdominopelvic CT. They all were performed RTX (5 weeks, radiation dose: 4500-5030 cGy) and concomittent chemotherapy (5-FU:425mg/mm2 & LV:20mg) using 24 hrs continuous infusion method for 5 days, twice). Surgery was performed at 5-6 weeks after CCRT. Median F/U was 65 mo (range 7-140 mo). Results: Male and female was 98 and 91, respectively. Median agewas 60 years (range 27-86 years). The mortality was 4 (2. 1%) and anastomotic leakge was 5 (2. 6%). The pathologic stage was as following: no residual tumor (NRT) 33 (17. 5%), I 55 (29. 1%), II 54 (28. 6%), III 47 (24. 9%). Overall recurrence rate was 17. 5% andlocal recurrence rate was 4. 8%. Most frequent distant metastasis organ was lung (14), liver (12), and other organs were distant LN (3), bone (3), carcinomatosis (1), brain (1), adrenal (1). The site of local recurrence was presacral space (4), pelvic wall(3), perineum (1), and anastomosis site (1). The multivariate analysis was concluded that T3/4 (HR:4. 2, 95% CI:1. 47-12. 24) and nodal metastasis (HR:3. 7, 95% CI: 1. 28-10. 42) were independent prognostic factors for recurrence. Tumor ABSTRACT BOOK Podium Papers regression status was not prognostic factor. The 5-year diseasefree survival for each stage was NRT (90. 9%), I (89. 9%), II (83. 7%), III (64. 4%), respectively, (P=0. 009). The 5-year cancerrelated survival was NRT (90. 6%), I (92. 7%), II (88. 8%), III (74. 2%), respectively (P=0. 03). Conclusions: The management of preoperative chemoradiotherapy for advanced rectal cancer revealed excellent results and morbidity and mortality were low. Besides pathologic stage III, survival difference within NRT, I, II was not. S056 THE INFLUENCE OF SURGICAL PROCEDURES TO THE POSTOPERATIVE URINARY FUNCTION AFTER AUTONOMIC NERVE PRESERVING OPERATION IN RECTAL CANCER SURGERY, Masahiro Tsubaki MD, Yuiti Ito MD, Masanori Fujita MD, Masakatu Sunagawa MD, First Department of Surgery, Dokkyo Medical University, School of Medicine Aim: The aim of this study is to clarify the influence of surgical procedures to the postoperative urinary function after autonomic nerve preserving operation (ANP) for the entire plexus in rectal cancer surgery. Material and Methods: 175 cases of rectal cancer operated from April 1998 to December 2006 were reviewed. All cases underwent curative surgeries. T0 carcinoma was excluded in this study. Tumor specific mesorectal excision (TSME) was performed for rectosigmoid and middle rectal cancers. When the cancers were located in the lower rectum or had the lowest margin below the peritoneal reflection with over T3 and or lymph node metastases, pelvic lymph node dissection was performed. In this procedure, three types of autonomic nerve preserving operation were performed. AN4+lat was ANP for the entire plexus, AN2 was ANP for the bilateral pelvic plexus and AN1 was ANP for the unilateral pelvic plexus only. The influence of the surgical procedures to the postoperative urinary function was evaluated by the rate of the patients who had spontaneous urination on the day of discharge. In addition, 12 patients in TSME and 11 patients in AN4+lat operation were questioned by International Prostate Symptom Score (IPSS) preoperatively and postoperatively (at least one year after operation). Results: TSME was performed in 125 cases and pelvic lymph node dissection was performed in 50 cases. The AN4+lat operation was performed in 24 cases. The local recurrence rate was 4. 0 % for all cases. All cases with TSME completely maintained their urinary function. 96. 0% of patients with preservation of autonomic nerves and pelvic lymph node dissection maintained urinary function on the day of discharge. Postoperative IPSS scores of the patients in AN4+lat operation were worse than in TSME. And postoperative IPSS scores of the patients in Milesf operation were worse than in sphincter preserving operation. Conclusion: We conclude preservation of autonomic nerves, even if pelvic lymph node dissection is performed, is important to maintain postoperative urinary function. However the postoperative urinary function would be influenced by the surgical procedures even if the entire plexus was preserved. S057 ULTIMATE ANUS PRESERVING OPERATION INCLUDING INTERSPHINCTERIC RESECTION FOR LOWER RECTAL CANCER EXTREMLEY CLOSE TO ANUS, Kazuo Shirouzu MD, Yoshito Akagi MD, Yutaka Ogata MD, Shinjiro Mori MD, Department of Surgery, Kurume University Faculty of Medicine, Japan Background: For a lower rectal cancer which was extremely near to the anus, an abdominoperineal resection (APR) has been generally performed for a long time. However, many patients do not hope a permanent colostoma even though they contract such cancers. Purpose: To avoid a permanent colostomy, we introduce an ultimate anus-preserving operation (UAPO) including intersphincteric resection (ISR) for such lower rectal cancer. Methods: Between 1982 and 2005, we encountered 219 patients with APR. Firstly, we pathologically examined about invasion or metastasis into the anal canal structures in the surgical specimens of APR. Then, we performed UAPO and investigated the oncologic and functional results. Pathologic results : When the lowest edge of the tumor was located above the dentate line (Pa cancer), the invasion and/or metastasis were rarely beyond the internal sphincter muscle (ISM). When the lowest edge was located below the dentate line (Pb cancer), then invasion and/or metastasis tended to be highly detected into the external sphincter www.isucrs.org/ muscle (ESM) beyond the ISM. Therefore, three different types of operation method were considered. One is intersphincteric resection (ISR) which is applied for Pa cancer, second is external sphincter resection (ESR) for Pb cancer, and another is combined resection of ESR+ISR for some of Pb cancer. Clinical results : We have just started the new operation since 2001. There were 13 patients with stage 1, 19 patients with stage 2, 6 patients with stage 3a, 5 patients with stage 3b, and 1 patient with stage 4. Twenty patients received ISR, 14 patients, ESR+ISR and 10 patients, ESR. Three patients had anastomotic leakage and one of those had an anastomotic stenosis. One patient had the necrosis of the reconstructive colon. Temporary ileostoma closure was performed for 40 patients on schedule between 3 and 10 months after initial operation. Patients with either ISR or ESR+ISR had relatively better anal function compared to patients with ESR. All patients were satisfied with successful anus preservation. We had recurrence in 3 patients with ISR, 1 with ESR+ISR, and in 2 with ESR. Anastomotic recurrence was not found in all patients. Overall the 4-year disease-free survival rate in the curative cases was 81. 3%. Conclusion: ISR and ESR are excellent new procedures for anus preservation. The anal function and the oncologic results were acceptable. S058 HISTOLOGICAL FACTORS CONTRIBUTING TO A HIGH RISK OF RECURRENCE OF SUBMUCOSAL INVASIVE CANCER (PT1) OF THE COLON AND RECTUM AFTER ENDOSCOPIC THERAPY, Ichiro Nakada MD, T. Tabuchi MD, T. Nakachi, A. Takemura MD, M. Katano MD, T. Tabuchi MD, Department of Surgery, Tokyo Medical University Kasumigaura Hospital Objective: To analyze the histological high-risk factors for recurrence of submucosal invasive carcinomas (pT1) of the colon and rectum after endoscopic therapy. MATERIALS and METHODS: We examined pT1 cancers treated primarily by endoscopic resection within a 23-year period. We compared recurrent and non-recurrent cancers, evaluating the following high-risk factors of the primary lesion: massive invasion, a surgical margin < 2 mm but negativity for cancer in the cut end, poorly differentiated adenocarcinoma (PD) (G3), undifferentiated carcinoma (G4), and/or positive angio-lymphatic invasion. We compared the ages, gender, location of the lesions, macroscopic type, size, histological type, angio-lymphatic invasion, desmoplastic response(DR) in the cancer stroma, and the surgical margin of the excised specimens between the patients with and those without recurrence. The following histological factors were defined as predictive of a low risk: minimum invasion, a surgical margin >2mm, well and moderately differenciated adenocarcinoma (G1, G2), and negative angio-lymphatic invasion. Results: We analyzed the records of 37 patients with pT1 cancers, including 15 with high-risk factors who underwent subsequent resection. Local recurrence with or without liver metastases developed in 4 of these 15 patients. The histological type was PD in three (75%) of the four recurrent lesions. All four (100%) lesions showed a desmoplastic response (DR). On the other hand, only 1 (9%) of the 11 patients without recurrence after subsequent surgery had a lesion with a small component of PD, and only three (27%) lesions showed a mild DR. We found no significant differences between recurrent and non-recurrent cases, although there were differences in the histological findings of the cancer stroma, particularly in the PD component and the DR between the two groups. Conclusion: Endoscopic therapy is inadequate for pT1 cancers with a histological PD component, and/or a DR in the cancer stroma. S059 15-YEAR EVOLUTION OF PENETRATING COLON MANAGEMENT AT A LEVEL I TRAUMA CENTER; WHAT HAVE WE LEARNED?, Elie Schochet MD, Indru T Khubchandani MD, Timothy S Misselbeck MD, Michael Matos BA, Sherrine Eid MPH, Lehigh Valley Hospital, Division of Colon and Rectal Surgery Introduction:: The management of penetrating colon trauma has undergone great change over the last century as wartime and urban experiences have supported a “repair first, and divert only when necessary” attitude as evidenced by multiple evidence-based guidelines adopted over the last ten years. We examine our 15-year experience at a level 1 trauma center to 49 ABSTRACT BOOK Podium Papers see if the adoption of these guidelines has improved outcomes. Methods: An IRB-approved review of a prospectively gathered trauma registry revealed 198 patients admitted from 1993 to 2007 with injuries to the colon. 57 (29%) patients were eligible following exclusions for serosal tears only, rectal injuries, death within 24 hours of presentation, and age <10. The database was compiled chiefly from trauma registry with individual charts and records examined when needed. Data was analyzed using SPSS. Results: Primary repair (PR) was performed on 16, resection and primary anastomosis (R+PA) was performed on 19, and repair or resection with diversion (DC) was performed on 22. Patients were predominantly male (84. 2%), young (mean 32 yrs), and injured by penetrating trauma (69%). Average ISS in the PR, R+PA and DC groups were 14, 18, and 19. 7 respectively with 72% of patients having other intrabdominal injuries. Average ICU LOS and hospital LOS were 4. 1 and 11 days, 14. 7 and 24 days, and 14. 4 and 23 days in the PR, R+PA, and DC groups respectively. Early morbidity occurred in 20% of the PR, 37% of the R+PA, and 53% of the DC group (NS when controlled for ISS), while late morbidity occurred in 10%, 26% and 0% respectively (p=. 005). Five patients in the RPA group needed eventual re-admission for SBO (n=2), ventral hernia (n=2), and anastomotic stricture (n=1). One patient required a stoma revision and 84% of patients followed underwent stoma reversal at a mean of 4. 6 months post-admission. While the rate of PR’s remained stable, the number of diversions has decreased and the rate of R+PA has almost doubled since 1998. Conclusions: The management of penetrating colon trauma remains a challenge. Although the number of diversions has decreased at our hospital in the ten years since the implementation of evidence-based guidelines, the high number of complications in the R+PA group is concerning. The small numbers in each group make direct comparisons difficult, however it would appear that in our institution, diversion remians a tried and tested modality with little morbidity and high reversal rates. COLORECTAL CANCER AND INFLAMMATORY BOWEL DISEASE S060 FUNCTION PRESERVING SURGERY FOR LOWER RECTAL CANCER INVOLVING LOWER URINARY TRACT IN MALE PATIENTS, Norio Saito MD, Takanori Suzuki MD, Masanori Sugito MD, Masaaki Ito MD, Akihiro Kobayashi MD, Toshiyuki Tanaka MD, Yusuke Nishizawa MD, Masaaki Yano MD, Yasuo Yoneyama MD, Yuji Nishizawa MD, Nozomi Minagawa MD, National Cancer Center Hospital East Purpose: Total pelvic exenteration (TPE) is the standard surgical procedure for patients with advanced low rectal cancer involving lower urinary tract organs such as the prostate and the urethras. We evaluated the feasibility of bladder and anus-sparing surgery as an alternative to TPE. Methods: Sixteen patients with advanced lower rectal cancer, involving involving the prostate and seminal vesicles or the urethral, underwent bladdersparing extended rectal resection with radical prostatectomy. The anus-preserving was also performed using intersphincteric resection (ISR) or very low anterior resection, if possible. These sixteen patients were general candidates for TPE. Oncologic outcomes and postoperative urinary and anal functions were estimated. Results: The surgical proadures were ISR with radical prostatectomy (n=9), very low anterior resection with radical prostatectomy (n=1), and abdominoperineal resection (APR) with radical prostatectomy (n=6). Cyst-urethral anastomosis (CUA) was performed in twelve patients, four patients received cystostomy on suspicion of cancerous invasion to the membranous urethral. Anal sphincter-preserving surgery was done in ten patients (Colo-anal anastomosis : 9, colo-anal canal anastomosis : 1). All patients had cancer-free surgical margins. There was no mortality. After a median follow-up period of 34 months, ten patients were alive without disease and three were alive with distant metastasis, although local recurrence was developed in two patients and distant metastasis in six. Twelve patients with CUA had satisfactory voiding function, and seven with preserving anus had acceptable bowel function after diverting stoma closure. Conclusions: These procedures as an alternative to TPE may yield improved postoperative functions without compromising oncologic outcomes. 50 ISUCRS XXII BIENNIAL CONGRESS S061 RADIOTHERAPY IN RECTAL CANCER - IS IT TIME FOR CHANGE? A QUALITATIVE ANALYSIS OF THE SURVEY OF MEMBERS OF ACPGBI ON PRELIMINARY MRC-CRO7 RESULTS, N Srinivasaiah MD, B Joseph MD, J Gunn MD, J Hartley MD, J R Monson MD, 1. Academic Surgical Unit, Castle Hill Hospital, University of Hull, Cottingham, UK Introduction: : The role of Neoadjuvant therapy (NAT) in management of rectal cancers has not reached a consensus in the UK . A survey of ACPGBI members indicated 39% have changed practice based on preliminary evidence from CRO7 trial. Change in clinical practice is driven by a number of factors. Aim: To find out factors influencing changing clinical practice in context to use of radiotherapy in rectal cancer. Methods: A postal questionnaire was sent to 400 members of the ACPGBI. Data for this subset of results is derived from the comments section on the questionnaire. Qualitative methodology was adopted to analyze the comments section. Results: Of 400 questionnaires, 200(50%) were returned. Of these only 52(26%) surgeons completed comments section. Themes emerging from thematic analysis are Patient-groups, Treatment, Evidence-based-practice (EBP), Professional-consensus and Service-provisions. Outcomes derived are individualize treatment, provide safer/less harmful treatment, increase role of MDTs, increase awareness of current evidence-based-literature, develop protocols/ guidelines, shorten delay in implementing evidence-based-practice and improve service provisions. Conclusions: Change is a slow and complex process influenced not only by data/ scientific evidence but by a combination of other factors. Some of them are Clinical decision making, Evidence based practice / Education, Research Translation and Organizational factors with Infrastructure / Resources. The derived outcomes would help in early implementation of EBP. S062 INSUFFICIENT LYMPHNODE DISSECTION IS AN INDEPENDENT RISK FACTOR FOR POSTOPERATIVE MORTALITY IN PATIENTS WITH STAGE II / DUKES B COLORECTAL CANCER, Mitsuru Ishizuka MD, Hitoshi Nagata MD, Kazutoshi Takagi MD, Keiichi Kubota MD, Department of Gastroenterological Surgery, Dokkyo Medical University Background: Recent progressison of radical colorectal surgery and chemotherpy decreasing postoperative mortality for stage II / Dukes B colorectal cancer (CRC). However, there are still postoperative mortality due to CRC. Objective: To investigate the risk factor of postoperative mortality for the patients with pathologically diagnosed stage II / Dukes B CRC. Methods: Prognostic significance was analyzed by Kaplan-Meier analysis, log rank test and univariate analyses using clinicopathological factors. Results: A total of 132 patients were evaluated. Univariate analyses using factors including sex, age, site of tumor, tumor number, type of tumor, maximum size of tumor, depth of tumor, lymph duct infiltration, venous infiltration, differentiation of tumor, the level of lymph node dissection, operational curability, C-reactive protein, albumin, serum CEA and administration of postoperative chemotherapy revealed that only insufficient lymph node dissection was associated with postoperative mortality (odds ratio 4. 818 95% C. I. 1. 394 - 16. 654 P = 0. 0130). Kaplan-Meier analysis and log rank test revealed that the group of insufficient lymph node dissection predicted a higher risk of postoperative mortality than the group of sufficient lymph node dissection group (P = 0. 0021). Conclusions: Insufficient lymphnode dissection is an independent risk factor for postoperative mortality in patients with stage II / Dukes B CRC. S063 COMBINED MANAGEMENT OF THE PERIANAL LESION IN THE CROHN’S DISEASE, José María Gallardo, Valle García Sanchez, Federico Gomez Camacho, Reina Sofía Hospital Introduction: 54% of the patients with Crohn disease (CD) have suffered, suffer or will suffer some perianal complication. In spite of the advances in the medical treatment until 80% of the patients require surgery. Objective: To evaluate a combined protocol of medical and surgical therapy in perianal CD. Patient and Methods: 22 patients were included. They were applied a protocol diagnosis-therapeutic agreed that it understood: 1) combined exploration in consultation, 2) Calculation of the modified index of perianal activity (MIPA), 3) Exploration endoscópica of the rectum. If pain or perianal fluctuation: 4) image technique ABSTRACT BOOK Podium Papers (pelvic Resonance and rectal Ultrasonography) and later on, 5) Exploration under anesthesia. Fistulas were defined according to the Park classification. Equally, they were subdivided in simple and complex. It was defined as remission and response to the total closing of all the fistula or, 50% of them respectively, in two revisions separate 4 weeks. Results: Time from the diagnosis of the CD until the CP was 46. 6±44, 8 months. 88. 9% was in treatment with inmunomoduladores (azatioprina). The average number of fistulas was of 1. 94±1, 77. 8% complex. The seton without knotting was the procedure more employee (72. 2%) with a permanency of 18. 09±5 weeks. Treatment with biological was used in 84. 3%. The remission and response percentage to the 2 months were 47. 1% and to the 6 months of 81. 8% (remission 17. 1% and answer 64. 7%). The MIPA passed to the 6 months of 6. 25+2. 5 to 1. 92+1. 7 (P=0. 002). Conclusions: The collaboration between gastroenterologists and surgeons seems indispensable to optimize the management of these patients. S064 IS THERE AN INFLAMMATION TENDENCY IN ASYMPTOMATIC PATIENTS WITH PELVIC ILEAL POUCHES FOR ULCERATIVE COLITIS AND FAMILIAL ADENOMATOUS POLYPOSIS?, Raquel F Leal MD, Marciane Milanski MS, Maria Lourdes S Ayrizono MD, Luciana R Meirelles PhD, João J Fagundes MD, Lício A Velloso PhD, Cláudio S Coy PhD, Coloproctology Unit, Dept of Surgery, and Cellular Signalization Laboratory, Campinas State University, São Paulo, Brazil Background: Pouchitis after total retocolectomy is the commonest complication in ulcerative colitis (UC) patients, while is quite rare in familial adenomatous polyposis (FAP). The immunopathogenesis of pouchitis is unclear and has been associated to the same UC inflammatory pathway. High levels of transcription factor STAT-1 are found in UC and are activated by INF-gama, being one of the TNF-alfa transcription factors. Aim: To evaluate the inflammatory activity in normal ileal pouch mucosa, by determining STAT-1 activation, and expressions of INF-gama, the suppressor factor SOCS-3, and the anti-inflammatory cytokine IL-10, in patients operated by UC and FAP. Methods: Eighteen asymptomatic patients submitted to total retocolectomy and J pouch, were evaluated, being nine with UC and nine with FAP. The control group consisted of nine individuals with normal ileocolonoscopy examinations. The endoscopic biopsy specimens were snap-frozen in liquid nitrogen. The activation of STAT-1 and expressions of INF-gama, SOCS-3, IL-10 were determined by immunoblot of total protein extracts. A routine hematoxilin-eosin analysis was performed. The absence of pouchitis was assessed by clinical, histologic and endoscopic parameters, according to the Pouchitis disease activity index. The patients were not taking any medications. ANOVA and Tukey-Kramer Test were applied. The local ethical committee approved the study and informed consent was signed by all participants. Results: STAT-1 activation was increased in patients with UC, when compared to FAP and controls (p<0. 05). Higher levels of INF-gama expression were observed in UC patients when compared to control group (p<0. 05). Otherwise, SOCS-3 and IL-10 expressions were similar in all groups (p>0. 05). Conclusion: Studying inflammatory activity in asymptomatic ileal pouches may explain the pathogenesis of the pouchitis, by determining a tendency of increased levels of INF-gama and STAT-1 in patients with UC, even without clinic and endoscopic evidence of pouchitis. These findings could explain a higher susceptibility to this inflammatory complication in UC when compared to FAP. The fact of SOCS-3 and IL-10 levels had no difference in all studied groups suggests that biopsy samples were taken from normal mucosa, and a balanced inflammatory activity between pro and anti-inflammatory cytokines may exist. S065 PULSE GRANULOMAS DISCOVERED IN SETTING OF CROHN DISEASE, Sukrit Narula, Yong-son Kim MD, Adelina T Luong MD, Janet C Nakamura MD, Dylan M Bach MD, Mark L Wu MD, University of California, Irvine School of Medicine Pulse granulomas are peculiar reactions to vegetable matter characterized by collagenous hyaline rings, inflammation, and vegetable matter. For unknown reasons, pulse granulomas rarely occupy the colorectum. The diagnosis of Crohn disease is challenging in cases that lack demonstrable transmural inflammation or sarcoid-type granulomas. Pulse granulomas deep to the muscularis propria would provide direct evidence www.isucrs.org/ for transmural inflammation and might facilitate a diagnosis of Crohn disease. We recently encountered 3 cases involving pulse granulomas occurring in the setting of Crohn disease. All cases had typical features of Crohn disease, including creeping fat, fissures, fistulae, architectural disarray, or sarcoid-type granulomas. The cases involved a 17-year-old boy, a 24-year-old woman, and a 36-year-old woman. Pulse granulomas occupied the subserosa of the colorectum or appendix in all cases. Surprisingly, 1 case also had pulse granulomas in 2 lymph nodes. All pulse granulomas had collagenous hyaline rings and chronic inflammation, and were with or without vegetable matter or barium-laden histiocytes. Some pulse granulomas were large enough to be seen at low magnification, while other pulse granulomas were tiny and appreciated only at high magnification. Rare pulse granulomas were overlooked initially because vegetable matter failed to polarize light. We present the first series of cases involving pulse granulomas occurring in the setting of Crohn disease. Pulse granulomas may be difficult to detect when tiny or when associated with nonpolarizable vegetable matter. Pulse granulomas in the subserosa or in lymph nodes are surrogate markers of transmural inflammation and can facilitate a diagnosis of Crohn disease. S066 SERUM ADIPONECTIN LEVEL IS POSSIBLY ALTERED IN INFLAMMATORY BOWEL DISEASE WITH SOME DIFFERENCE BETWEEN ULCERATIVE COLITIS AND CROHN’S DISEASE, Natsuko Ue MD, Giichiro Tsurita PhD, Joji Kitayama PhD, Hirokazu Nagawa PhD, University of Tokyo Hospital Background: Diet and lifestyle are known to change the adipose tissue metabolism. Adiponectin (ADP), an emerging mediator of immune response and inflammation, secreted by adipose tissue, could be a key to pathogenesis of inflammatory bowel disease (IBD) and a potential therapeutic drug, but little is known yet. Purpose: To see if ADP level is altered in IBD. Methods: Patients with ulcerative colitis (UC) or Crohn’s disease (CD) were examined for serum ADP levels. Clinical records were reviewed for clinical disease severity and inflammatory biomarkers, white blood cell count (WBC), high-sensitivity C-reactive protein (CRP), and erythrocyte sedimentation rates (ESR). We examined for their possible association. We also compared data with those of patients with other diseases (OT), acute appendicitis or acute diverticulitis. Results: Total of 34 patients, 18 with UC (male/female of 6/12, median age of 43. 5), eight with CD (5/3, 31. 0), and eight with OT (4/4, 63. 5), were examined. (1) Median total ADP level (tADP) did not show significant difference among disease groups (5. 33 in UC, 5. 17 in CD, 4. 34 in OT), nor in sex, nor in age. Percentage of high, medium, or low molecule ADP was correlated with tADP and neither showed significant difference among disease groups. (2) Patients with more aggressive disease with higher levels of WBC, CRP, or ESR tended to show relatively lower tADP levels in UC, but relatively higher in CD. There seemed to be no tendency in OT, all in which were with significantly higher CRP than IBD cases (101. 90 vs 5. 90 mg/l). (3) When IBD patients experienced flares, serum tADP level seemed to shift in a short time in a small range, and was inversely correlated with clinical activity, CRP or ESR, both in UC and CD. Conclusion: Serum ADP level, in acute phase of IBD, probably changes in inverse correlation with severity of inflammation and ADP is possibly down-regulated constitutively in chronically severe UC; These two results are consistent with our previous knowledge on ADP. Interestingly, however, ADP seems to be up-regulated in chronically severe CD. This encourages us for future study on ADP in IBD, for it may be a clue to molecular mechanism of IBD, the difference of CD from UC, in association with distinct adipose tissue or impact of specific diet and lifestyles. S067 LONG-TERM RESULTS OF ILEOCAECAL STRICTUREPLASTY IN THE TREATMENT OF CROHN’S ILEITIS, Francesco Tonelli° MD, Marilena Fazi* MD, Tatiana Bargellini° MD, Francesco Giudici° MD, Giuseppe Canonico° MD, Carmela Di Martino° MD, ° Department of Clinical Phisiopathology, * Department of Medical and Surgical Critical Care From October 1996 to May 2000 13 patients (5 male and 8 female, mean age 39 yrs/range 23-55) affected by Crohn’s Disease (CD) of the terminal ileum have been operated adopting a personal 51 ABSTRACT BOOK Podium Papers technique of ileocaecal Finney-shaped strictureplasty. Eight of these pts presented also other localization of CD: proximal ileum (4), colon (2 caecum, 1 transverse, 1 left/transverse) and rectum plus caecum (1 pts). Twelve pts were at the first surgical treatment, while 1 pt was resected for a jejunum-ileal form of CD 8 years before. The ileitis was characterized by a single long stricture in 12 cases and by two strictures (9 and 2 cm long) in the other one patient. At the end of the surgical procedure the length of the ileo-caecal strictureplasty was as mean of 16 + 2 cm (range 6-30). In the 4 pts with associated proximal ileal strictures we have performed respectively in two pts single and multiple (3) sxpl according to Heineke-Mickulicz, in the third a side-to-side isoperistaltic sxpl and in the last one a Finney sxpl. During the p. o period no morbidity or mortality were recorded. Mean length of stay in hospital was of 9. 9 + days (range 7-13). At discharge mesalazine was prescribed in all patients. At a mean follow-up of 10 yrs (range 90 -134 months) we have observed in 4 pts recurrence at the site of the ileocaecal sxpl. In three instances symptoms were controlled by medical therapy, while a surgical procedure (resection of the previous ileocaecal sxpl) was necessary in the other pt after 68 months. Other two pts with associated colonic disease complain symptoms related to active colitis controlled by means of medical therapy. The results of the present series show that pts undergoing ileocaecal strictureplasty are no more likely to require further operation than those who have a resection as first procedure. PLENARY SCIENTIFIC SESSION: BEST PAPERS S068 TREATMENT OF FISTULA-IN-ANO BY ANAL FISTULA PLUG: A PROSPECTIVE STUDY FROM ASIA, Pankaj Garg MS, Fortis Super Specialty Hospital, Mohali, Punjab, India Purpose: The aim of this study was to determine the efficacy of the Surgisis® AFP™ (anal fistula plug) in the treatment of fistulain-ano. Methods: Over a period of one and a half years, 28 patients presenting with cyrptoglandular fistula-in-ano were prospectively studied. The number of tracts, fistula location, number of previous procedures, and co-morbid conditions that could potentially affect outcome were noted. Fistula tract passing through the upper twothirds of external sphincter complex (defined as the tissue between pubo-rectalis sling and lower end of anal canal) were taken as high fistula. All procedures were performed under regional anesthesia with the patient in the lithotomy position. After washing the tract with hydrogen peroxide, a seton was used to guide the AFP™ into the fistula tract. The plug was anchored with 2-0 Vicryl® suture at the primary and secondary openings. The secondary opening was kept partially open to allow any residual drainage. Results: Two patients had insufficient follow-up and one was lost to follow-up. For the remaining 25 patients, mean age was 41±9. 1 years and follow-up ranged from 4-15 months (mean= 226 days). 18 patients had single tracts, and 7 patients had multiple tracts with a total of 34 tracts. 20/25 had high fistulae and 13/25 had recurrent fistulae. Overall, final patient success rate, defined by closure of all fistula tracts was 72% (18/25). The success rate was 83% in patients with a single fistula tract (15/18) compared to 43% in patients with multiple tracts (2/6) (p = 0. 06, Fisher’s exact test). Patient with Diabetes Mellitus had lower (1/4, 25%) cure rates than non diabetic patients(17/21, 81%)(p= 0. 052, Fisher’s exact test). The fistula location, high - 14/20(70%) versus low fistulae 4/5(80%), (p=1. 0, Fisher’s exact test) and previous procedures done, recurrent8/13(62%) versus non-recurrent fistulae- 10/12(83%), (p=0. 37, Fisher’s exact test) had no significant bearing on the outcome. The surgical procedure was safe and well tolerated, with minimal pain and morbidity in majority of patients. Conclusions: Closure of fistula-in-ano with the Surgisis® AFP™ was successful in 72% of the patients. Patients with multiple tracts and diabetes had poorer results but it was not significant. Recurrent fistula and location of fistula didn’t affect the outcome. The procedure is well tolerated, with minimal pain and morbidity. Although long-term results are awaited, use of the Surgisis® AFP™ appears to be a safe and effective alternative to more traditional invasive procedures. S069 IDEAL BOWEL RESECTION AND MARGINS IN COLON CANCER, Yojiro Hashiguchi MD, Hideki Ueno MD, Yoshiki Kajiwara MD, Jiro Omata MD, Koichi Okamoto MD, Toru Kubo MD, Tomomi Fukazawa MD, Kazuo Hase MD, Hidetaka Mochizuki 52 ISUCRS XXII BIENNIAL CONGRESS MD, Department of Surgery, National Defense Medical College Background: The ideal extent of a bowel resection is defined by removing the blood supply and the lymphatics at the level of the origin of the primary feeding arterial vessel. It is suggested in General Rules for Clinical and Pathological Studies on Cancer of the Colon, Rectum and Anus (the 7th Edition) published by Japanese Society for Cancer of the Colon and Rectum that 10 cm of normal bowel on either side of the primary tumor should be removed. Furthermore, if two feeding vessels are identified within 10 cm of normal bowel, both vessels should be excised at their origin. In United States Guidelines 2000 for Colon and Rectal Cancer Surgery published by the National Cancer Institute suggested that 5 cm of normal bowel on either side of the primary colon tumor appears to be adequate. [Purpose] We retrospectively analyzed 466 pathologic specimens of patients with curatively resected colon cancer from 1988 to 1997 at our institution, to clarify the ideal bowel resection and margins. [Results]The incidence of epicolic lymph node (LN) metastases within the size of the primary tumor was 29%. The incidence of LN metastases within 5 cm of normal bowel on oral side of the primary tumor was 15% and that on anal side 11%. The incidence of metastases from 5 cm to 10 cm on oral side was 0. 5% and that on anal side 1. 6%. Incidence of metastases more than 10 cm on oral side was 0. 2% and that on anal side 0%. The incidence of lymph node metastases along two feeding vessels from one primary tumor was only 1. 3% (3 cases). All these three patients died within a year after surgery, indicating extremely poor prognosis for patients with such aggressive colon cancers. [Conclusion] Removal of 5 cm of normal bowel on either side of the primary colon tumor appears to be adequate. Excision of one feeding vessel is adequate unless primary tumor is equidistant from two feeding vessels. S070 LONG-TERM RESULTS OF TREATMENT WITH BOTULINUM TOXIN TYPE A FOR OBSTRUCTIVE OUTLET CONSTIPATION ARE VERY DISAPPOINTING. , B Santoni MD, D Vivas MD, B Safar MD, J Nogueras MD, E Weiss MD, S Wexner MD, D Sands MD, Cleveland Clinic Florida Hypothesis: This study aimed to assed the long-term results in patients with outlet obstructive evacuation who underwent Botulinum toxin type A injections. Methods: Following IRB approval, a retrospective chart review was undertaken from 1992-2006 including all patients who received Botulium Toxin Type A injections into the puborectalis muscle for obstructive outlet constipation. Charts with incomplete data were excluded. Age, gender, anal manometry, pudental nerve latency and EMG studies, defecography, previous pelvic surgery and other types of treatment were all examined. Patients were contacted by telephone and postal survey and asked to complete a questionnaire to assess the satisfaction with the result of the treatment. Results: 55 patients (35 women) of mean aged 59. 6 (range 25-94) years were identified as having obstructive outlet constipation who underwent Botulinum toxin injection. 29 patients replied to the questionnaire. Before the Botulinum toxin injection, 4 with neurological disturb; 4 with psychological problems; 9 with rectal pain. Before the Botulinum toxin injection, 2 underwent ostomy; 1 STARR procedure; 1 sigmoidectomy with rectopexy; 4 total abdominal colectomy with ileorectal anastomosis. Paradoxical puborectalis contraction was noted in 20/29 EMG exams and in 19/23 defecographic evaluations. 25 of the 29 patients had failed 0-10 sessions of biofeedback therapy and 16 patients were laxative dependent. 24 patients underwent 1-2 injections of Botulinum toxin interim 5 patients received 3-5 injections. At a mean follow-up of 35. 8 (range 1-103) months. 3 patients reported fecal incontinence, 3 had urinary incontinence and 14 continued to require laxatives to evacuate. Only 8/29 patients (28%) were satisfied with the results. Conclusion: Despite initial enthusiastic results, longer-term follow-up revealed very poor results. Between limited efficacy and the potential morbidity of both urinary and fecal incontinence. The role of Botulinum toxin type A injection for paradoxical puborectalis contraction is very limited. S071 DIVERTICULITIS IN THE UNITED STATES: 1991 2005 CHANGING PATTERNS OF DISEASE, TREATMENT, David A Etzioni MD, Andreas M Kaiser MD, Robert W Beart MD, Thomas M Mack MD, University of Southern California ABSTRACT BOOK Podium Papers Objectives: Diverticular disease imposes an impressive clinical burden to the US population, with over 300, 000 admissions and 1. 5 million days of inpatient care annually. Consensus regarding the treatment of diverticulitis has evolved over the last decade, with increasing advocacy of primary anastomosis for acute diverticulitis, and non-operative treatment of recurrent mild/ moderate diverticulitis. We sought to analyze whether these changes are reflected in patterns of practice in a nationallyrepresentative patient cohort. Methods: We used the 1991-2005 Nationwide Inpatient Sample to analyze the care received by 381, 000 patients admitted with acute diverticulitis and 51, 000 patients operated electively for diverticulitis. Census data were used to calculate population-based incidence rates of disease and surgical treatment. Weighted logistic regression with cluster adjustment at the hospital level was used for hypothesis testing. Results: Between 1991-1995 and 2001-2005, population-adjusted rates of admission for acute diverticulitis increased by 18%, but dramatically within patients aged 18-44 (116% increase). Rates of elective operations for diverticulitis rose more quickly, with a 51% increase in rate within the overall population and massive increase (188%) in individuals aged 18-44. the ovaries in colorectal malignancy is prognostically poor. Furthermore, macroscopic and histochemical similarities make differentiation between primary mucinous and metastatic deposits to the ovary difficult. We examined this complex picture of metastatic ovarian cancer in association with colorectal malignancy. Methods: Pathological database and case note review of consecutive patients, referred to a single centre over an 8 year period, with primary ovarian cancer and a previous, or subsequent, history of colorectal adenocarcinoma. Each carcinoma was defined histologically/immunologically from resected specimens. Results: 26 cases were identified. 8 patients (31%, median age 60 years) had colectomy prior to oophrectomy (median time lapse 17 months, range 3-60 months). In this group, colonic metastatic adenocarcinoma to the ovary was observed in 75%. 18 patients (69%, median age 55 years) had oophrectomy prior to colectomy (median time lapse 11 months, range 3-60 months). In these patients, colonic metastatic adenocarcinoma was identified in the ovaries of 4 (22%) and mucinous ovarian carcinoma in 3 (17%). 8 patients (44%) receiving oophrectomy first, presented with altered bowel habit and/or rectal bleeding, including all with mucinous or metastatic ovarian carcinoma. Only 2 were referred, following oophrectomy, for colonic visualisation, identifying their primary cancer. Conclusions: Ovarian neoplasia following colorectal cancer is indicative of metastatic disease and avoidable through prophylactic oophrectomy. Colonic investigation should be performed in all cases of ovarian tumours with suspicious bowel symptoms and considered in mucinous ovarian carcinoma. COLORECTAL CANCER AND ANORECTAL DISEASES I Multivariate analysis found no evidence that primary anastomosis is becoming more commonly used. Conclusions: We are the first to report dramatic changes in rates of treatment for diverticulitis in the US. The causes of this emerging disease pattern are unknown, but certainly deserve further investigation. For patients undergoing surgery for acute diverticulitis, there was little change over time in the likelihood of a primary anastomosis. S072 MANAGEMENT OF ACUTE MALIGNANT LARGE BOWEL OBSTRUCTION WITH SELF-EXPANDING METAL STENT, J-P Arnaud MD, S Mucci-Hennekinne MD, K Meunier MD, E Lermite MD, C Teyssedou MD, A Hamy MD, Department of Visceral Surgery, Chu-Angers, France Background: colorectal stents are being used for palliation and as a “bridge to surgery” in obstructing colorectal carcinoma. The purpose of this study was to review our experience with self-expanding metal stents (SEMS) as the initial interventional approach in the management of acute malignant large bowel obstruction. Methods: between February 2002 and May 2006, 67 patients underwent the insertion of a SEMS for an obstructing malignant lesion of the left-sided colon or rectum. Results: in 55 patients, the stents were placed for palliation, whereas in 12, they were placed as a bridge to surgery. Stent placement was technically successful in 92, 5% (n=62), with a clinical success rate of 88% (n=59). Two perforations occurred during stent placement treated by an emergency Hartmann operation. In intention to treat by stent, the peri-interventional mortality was 6% (4/67). Stent migration was reported in 3 cases (5%) and stent obstruction in 8 cases (13, 5%). Of the nine patients with stents successfully placed as a bridge to surgery, all underwent elective singlestage operations with no death or anastomotic complication. Conclusions: stent insertion provided an effective outcome in patients with malignant colonic obstruction as a palliative and preoperative therapy. S073 METASTATIC OVARIAN AND COLORECTAL CANCER: TWO ORGANS, ONE DISEASE, J D Terrace MD, R J Skipworth MD, C Bourne MD, D N Anderson MD, Academic Unit of Coloproctology, University of Edinburgh Introduction: Whilst oophrectomy is routinely performed in post menopausal women during gynaecological surgery, prophylactic oophrectomy during colorectal cancer resection remains controversial. Synchronous or metachronous involvement of www.isucrs.org/ S074 EXAMINATION OF ANAL PRESERVATION WITH ANAL SPHINCTERIC RESECTION FOR VERY LOW RECTAL CANCER, Yoshito Akagi MD, Kazuo Shirouzu MD, Yutaka Ogata MD, Naruya Ishibashi MD, Masataka Ushijima MD, Hidetugu Murakami MD, Department of Surgery, Kurume University In our department, we have adopted a preservation of anus with resection of internal or external sphincter resection for the lower rectal canceriISR, ESRj that a inferior border of tumor is present in a vicinity of dentate line. We report the clinical results of this operative method which we experienced in our department until now and examine problems by the present. Subject and Methods: For 52 cases that we have performed ISR or ESR from 2001 to 2006, we reviewed oncological results and anal function. Results: Postoperative complications: The complication after operation were acknowledged 19. 2% (10/52), 3 cases of anastomosis leakage, 3 cases of intrapelvic abscess, 2 cases of anastomotic region mucosal necrosis 2, a constructed bowel necrosis and ileus. Anal Function: On anal pressure examination after one year from closure of temporary ileostomy, Maximum resting pressure(MRP) with 36. 3cmH2O was lower than its value before closure of ileostomy. But, the Maximum squeeze pressure(MSP) gradually recovered with 119. 6cmH2O. The recurrence rate after curative resection was 11. 5% (6/52). The local recurrence was 7. 7%(4/52) of 2 cases in lateral lymph node and 2 cases of intra pelvic space. Distant metastasis was each one case to liver and to lung. Conclusion: It seems that ISR and ESR for very low rectal cancer are acceptable at present time seeing from an oncology and an anal function. However, it is necessary for us to devise the prevention of complications and a recurrence. S075 INCIDENCE OF COLONIC POLYPS AFTER BARIATRIC PROCEDURES. , B Bashankaev MD, M Khaikin MD, D Melero MD, D Vivas MD, B Santoni MD, D Sands MD, E Weiss MD, J Nogueras MD, S Szomstein MD, R Rosenthal MD, S Wexner MD, Cleveland Clinic Florida Background: There are data showing increased risk of colorectal cancer in the obese population. Colon polyps have proven to be a premalignant stage in the development of colorectal cancer. Aim: To evaluate the incidence of colonic polyps in patients who underwent bariatric surgery and to compare this incidence to the nonbariatric surgery population. Methods: After the IRB approval, retpospective review of the prospectively entered bariatric surgery and endoscopy databases was performed to identify all patients 53 ABSTRACT BOOK Podium Papers who had bariatric surgery and colonoscopy over a period from February 2000 to April 2007. This Surgical, Morbidly Obese Group (SMOG) was matched to the group of colonoscopy patients without surgery, who didn’t have morbid obesity (Non-Obese Group, NOG) by age and gender. BMI before surgery and at time of colonoscopy, age, gender, type of procedure, colonoscopy findings and pathology results were recorded. Results: 70 patients of the 2332 bariatric surgery patients (SMOG) were identified and compared to 70 out of 2165 patients from the endoscopy database (NOG). There were no differences between the groups in age and gender. However, there was statistically significant difference in BMI at time of colonoscopy (31 vs. 28. 4, p=0. 036). 21. 4% patients in the SMOG and 25. 7% in the NOG were high risk patients. SMOG colonoscopy was postoperatively performed after a mean period of 23. 2 (1-55) months. Two third of patients in both groups had no polyps (70% SMOG, 77% NOG). Most polyps were single and equally distributed between the right and the left colon. Half of the polyps in both groups were hyperplastic polyps of 3 - 4 mm in size. There was no cancer identified in the NOG, however, in the SMOG adenocarcinoma was found in 2 patients (8. 3%), 1 in the cecum and 1 in the sigmoid colon. Both patients had no high risk of colorectal cancer and postoperative colonoscopy was performed in 55 and 33 months, respectively. Conclusions: The incidence of colorectal polyps and cancer was not signifacantly different between SMOG and NOG patients during the mean postoperative period of 2 years. However polyp distribution and pathologic characteristics were similar between both groups. Although wasn’t stastically significant, this study shows a trend to develop malignant polyps in morbidly obese group. Long term follow-up with preoperative and postoperative colonoscopy are needed to accurately determine any role of bariatric surgery in the development of colorectal cancer. and finally surgical sphincterotomy if these methods fail. This study was designed to compare pharmacologic therapy using glyceryl trinitrate with lateral internal sphinchterotomy in young, otherwise healthy males. Methods: From March 2005 to August 2007, 30 consecutive young males (age range 21 to 40 years) with a chronic anal fissure, were randomized to be managed by either topical glyceryl trinitrate or lateral internal sphincterotomy. Pretreatment, pain scores were obtained using a numerical scale and continence scores were obtained using the Cleveland Clinic scoring system. Post-treatment, pain scores were assessed on post-treatment day 2 , 7 and 28, continence and fissure healing at 3 months postoperatively. Patient satisfaction with therapy was assessed at 3 months using a numerical scale. Compliance with pharmacological therapy was also assessed. Results: 15 patients underwent pharmacological therapy by topical application of glyceryl trinitrate (4mg/g, twice daily). 15 patients underwent lateral internal sphinchterotomy utilizing in an ambulatory setting. In both groups, the mean age was 30±6 years. Pain scores were significantly lower in the surgical group on post-treatment days 2 (1. 5± 0. 27 versus 5. 0±1. 2, p<0. 05) and 7 (0. 4±0. 16 versus 2. 9±0. 7, p<0. 05). Pain scores on post-treatment day 28 were not significant. Patients in both groups achieved similar continence scores at 3 months. In the surgical group all fissures had healed at 3 months. In the pharmacologic group the healing rate was 67% at 3 months. Patient satisfaction scores were significantly higher in the surgical group (3. 7±0. 4 versus 1. 5±0. 3, p<0. 05). Sixty percent of patients in the non-surgical group were totally compliant with pharmacologic therapy, 20% were partially compliant and 20% were non-compliant. Conclusion: Lateral internal sphinchterotomy may be offered as the first line of therapy in carefully selected young, otherwise healthy male patients. S076 OBSTRUCTIVE COLORECTAL CANCER, PROGNOSIS AND COST-EFFECTIVENESS ACCORDING TO THERAPEUTIC OPTIONS, Ui Sup Shin MD, Chang Sik Yu MD, Sang Nam Yoon MD, Dae Dong Kim MD, Jin Cheon Kim MD, Department of Surgery, University of Ulsan College of Medicine and Asan Medical Center, Seoul, Korea Background: The aim of this study was to compare treatment outcomes and cost-effectiveness among the stage operation, on-table lavage, and stent insertion. Methods: We reviewed the medical records of 116 patients who received curative operation for obstructive colorectal cancer from 1992 to 2007. Sixty-six patients underwent the stage operation (diversion group), 23 patients underwent on-table lavage (lavage group), and 27 patients underwent the stent insertion (stent group). Median follow-up period was 21 months (1~130 months). Results: There was no significant difference in age, comorbidity, stage, and histologic grade among the three groups. Compared with the other groups, however, significantly higher incidence of lymphovascular invasion was observed in the stent group (p<0. 05). The diversion group has higher postoperative complication rates in the areas such as wound infection and intestinal obstruction (p=0. 003). Operation times and hospital days were significantly longer in the diversion group and no significant difference was observed between the lavage and stent groups (p<0. 001). The mean of total costs was U$15, 762 for the diversion group, U$10, 543 for the lavage group, U$10, 838 for the stent group (p<0. 001). Although we could not find any significant difference, stent group has a lower 2 year relapse free survival rate than those of the diversion and lavage groups. Tumor recurrence and survival rates were not significantly influenced by therapeutic options. Conclusions: Compared with the traditional stage operation, on-table lavage and stent insertion had no negative impact on the recurrence and survival rates with less complications and better costeffectiveness. But long term follow up and case accumulation is needed to evaluate the oncologic safety of stent insertion. S078 TREATMENT OF HEMORRHAGIC RADIATION PROCTITIS WITH FORMALIN APPLICATION UNDER DORSAL PERINEAL BLOCK. , Narimantas E Samalavicius PhD, Alfredas Kilius, Darius Norkus, Arvydas Burneckis, Konstantinas P Valuckas, Oncology Institute of Vilnius University, Santariskiu 1, Vilnius, Lithuania Aim of the study was to evaluate results of treatment of hemorrhagic radiation proctitis with formalin application under dorsal perineal block in patients, who received radiation therapy for prostate cancer. Patients and Methods: During two years, 2006-2007, 29 patients underwent formalin application under dorsal perineal block for hemorrhagic radiation proctitis. All patients were irradiated of prostate cancer. Age 60-76 years, on an average 70 years. In one case hemorrhage occurred 1 week after treatment, in rest of the cases 3 to 24 months after treatment, on an average 10 months. 15 patients reported daily blood in stools, 14 - 2 or 3 times a week. 2 patients received blood transfusions for severe anemia, one even underwent colostomy to control severe bleeding. According to endoscopic classification of chronic radiation-induced proctopathy, 6(20, 7%) had grade I, 16 (55, 2%) grade II and 7 (24, 1%) grade III proctitis. All patients were referred for formalin therapy after failure of noninvasive management. Formalin application has been performed as a day case in an operating theatre, dorsal perineal block achieved injecting a mixture of lidocaine and bupivacaine solution. A gauze soaked with 4% formalin has been applied to the whole diseased rectal mucosa for 4 minutes. If patient had no improvement after 4 weeks, he was advised to repeat the procedure. 21 (72, 4%) patients underwent single procedure, and 8 (27, 6%) - two. Results: 2 to 26 months after treatment, patients 25 were interviewed (4 lost to follow-up). 14 (56%) reported complete cure, 5 (20%) significant improvement, and 6 (24%) no change (3 of them underwent single, and 3 two applications). One patient, who underwent colostomy for previous episodes of bleeding from radiation proctitis, was cured and colostomy was closed. One patient developed rectal mucosal damage after second application, due to which received prolonged conservative management, though bleeding stopped completely. Conclusion: Application of 4 % formalin for 4 minutes for hemorrhagic radiation proctitis under dorsal perineal block in patients who received radiation therapy for prostate cancer was simple, safe and effective, and 76% of patients were cured or markedly improved after treatment. S077 CHRONIC ANAL FISSURE IN YOUNG MALES, Constantine P Spanos MD, Theodore Syrakos MD, Dimitris Kiskinis MD, 1st Department of Surgery, Aristotelian University, Thessaloniki, Greece Purpose: Chronic anal fissure is a relatively common disorder in young males. Standard therapy algorithms begin with conservative treatment, followed by pharmacologic treatment 54 ISUCRS XXII BIENNIAL CONGRESS ABSTRACT BOOK Podium Papers S079 FLAPS IN COLORECTAL SURGERY - A PLASTIC SURGEONS VIEW, Stephan Spendel PhD, Johann Pfeifer PhD, Michael V Schintler PhD, Gerhard Kreuzwirt RN, Bengt Hellbom PhD, Erwin Scharnagl PhD, Division of Plastic and Reconstructive Surgery, Medical University Graz, Austria Introduction: Exstirpative operations of the perineum often include preoperative or postoperative radiation therapy. Without vascularized tissue reconstruction, these wounds often break down, becoming problem wounds. Morbidity associated with the non healing perineal wound remains the most common complication after proctectomy. Muscle and musculocutaneus flaps can solve these problems. For defects due to trauma or infections in the abdominal and perineal region reconstruction with flaps may also be necessary. Patients and Methods: A consecutive series of 31 patients were retrospectively reviewed between 2002 and 2007. All patients were operated interdisciplinary with the colorectal surgeon specialist. Flaps were used in patients with rectovaginal and chronic anal fistulas, infections, malignant skin tumors, sacral and rectal tumors, tumors of the genital region and in patients with incontinence for preliminary measures for implantation of artificial bowel sphincters. Results: 35 flaps in 31 patients were performed. Types and frequency of flaps using for reconstruction as follows: rectus abdominis flap (8), groin flap (2), glutaeus maximus flap (2), tensor fascia latae flap (3), gracilis flap (6), pudendal thigh flap (5), free scapular flap (1), local transposition flap (8). In all patients no flap was lost, minor early complications took place in 14%, partial flap necrosis in 10%. Reoperation was necessary in 18%. Conclusion: In our clinic minor flaps such as the house flap, martius flap etc. are commonly done by the colorectal surgeon. In some special cases complex reconstruction is required and thus we recommend an interdisciplinary approach with a plastic surgeon. S080 FISTULA-IN-ANO IN INFANTS: OPERATIVE OR NONOPERATIVE MANAGEMENT? Shota Takano MD, Shin Namikawa MD, Yoriyuki Tsuji MD, Kazutaka Yamada MD, Masahiro Takano MD, Coloproctology center Takano Hospital Background: Nonopetation management is mainly selected in treatment of fistula-in-ano in infants recently. However, not few parents of the patents want to undergo surgery early time, because repeated pain and high fever of infant are to be mental fatigue of their patients. In our institution, we perform fistulotomy for patients under 12 months if their parent wants. Fistulotomy is the accepted treatment for infants with fistula-in-ano. We analyzed fistulotomy of fistula-in-ano by comparing with nonoperating management. Methods and Results: A retrospective review was done of 93 infants with fistula-in-ano between the years 1997 and 2007 in our institution. All patients were boy. 40 patients were performed fistulotomy. 53 patients were underwent conservative management. Mean age at onset of symptoms was 3. 7 +/- 2. 5 months. In the group of fistulotomy, mean age at operation was 6. 7 +/- 4. 2 months. The mean duration between onset of symptom and operation was 2. 9 +/- 2. 1 months. None of patients who were performed fistulotomy had recurrent fistula during followup period. But 6 patients (14. 3%) is followed by new fistula-in-ano in other part. 3 patients of them were underwent re-operation. Conclusions: Fistula-in-ano and perianal abcess give children pain and high fever. And then, it gives their patients mental fatigue and time burden. Fistulotomy for under 12 months patients is an effective method if their patients want. Surgical management is more effective in respect to the mental and time factor. S081 PATIENT’S SELF-IRRITATING SETON INDWELLING DURING MODIFIED HANLEY OPERATION FOR HORSESHOE FISTULA, Nahmgun Oh PhD, Hyuk-Jae Jung MD, Department of Surgery, Pusan National University Hospital, Busan, South Korea Purpose: Fistula is a condition that can usually be treated by surgery, but has problems of recurrence, fecal incontinence, and postoperative wound infection. The modified Hanley operation which is usually applied for the treatment of horseshoe fistula showed reduced anal sphincter injury compared to the classic Hanley operation, but still involves a long wound healing duration, during which long-term outpatient treatment is required, making the daily life of a patient inconvenient. Hence, in order to reduce inflammation at fistulotomy wound sites, the present authors have www.isucrs.org/ developed a pulsatile self-irrigating seton procedure for use in the modified Hanley operation. In order to analyze clinical results after surgery for an existing simple drainage seton procedure and the newly modified self-irrigating seton procedure in the modified Hanley operation, the present study was performed. Subjects and Method: This study was performed on 24 horseshoe fistula patients who have received surgery in the present hospital for a period from January 1999 to December 2005. For comparison, the 24 patients who have received the modified Hanley operation were divided two groups: Group A consisting of 12 patients subjected to the existing simple drainage seton procedure; and Group B consisting of 12 patients subjected to the self-irrigating seton procedure. In Group A, general outpatient treatment was performed therein, and in Group B, the patients themselves who have been discharged from the hospital after surgery performed pulsatile irrigation daily with normal saline containing antibiotickanamycin dissolved by personal manual infusion. During the study, the two groups were comparatively analyzed for purulent discharge duration, seton indwelling duration and recurrence rate. Results: In the comparison between the two groups, the purulent discharge duration was 29. 75 ¡¾ 4. 27 days for Group A and 18. 75 ¡¾ 2. 90 days for Group B, and the seton indwelling duration was 32. 58 ¡¾ 3. 70 for Group A and 21. 58 ¡¾ 3. 09 for Group B. Also, the recurrence occurred in 2 cases (16. 7%) for Group A and 1 case (8. 3%) for Group B. The present method having a pulsatile irrigation in addition to the role of the drainage seton procedure which has previously been used is considered to be significantly effective in reduction of purulent discharge duration and seton indwelling duration compared to the case of performing surgery using only drainage seton, and seems to be a recommendable method in performing the modified Hanley operation for treating horseshoe fistula. Conclusion: This pulsatile self-irrigation seton is considered to be a new effective modification for drainage of deep-seated curettage site in complicated high anal fistula. COLORECTAL CANCER AND ANORECTAL DISEASES II S082 VALIDATION OF USEFULNESS OF LYMPH NODE DISSECTION FOR COLORECTAL CANCER IN JAPAN, USING THE REDUCTION RATE OF LYMPH NODE RECURRENCE, Hirotoshi Kobayashi MD, Masayuki Enomoto MD, Tetsuro Higuchi MD, Masamichi Yasuno MD, Hiroyuki Uetake MD, Satoru Iida MD, Toshiaki Ishikawa MD, Megumi Ishiguro MD, Takatoshi Matsuyama MD, Haruhiko Aoyagi MD, Sayaka Shimizu MD, Satoshi Okazaki MD, Kenichi Sugihara MD, Tokyo Medical and Dental University, Dept of Surgical Oncology Background: The aim of this study was to clarify the usefulness of lymph node dissection for colorectal cancer, using the reduction rate of lymph node recurrence. Method: We enrolled 512 patients who underwent curative resection for colorectal cancer between January 1991 and December 2000 at the Tokyo Medical and Dental University. The reduction rate of lymph node recurrence was defined as follows: RLN = X/(X + Y). gXh is the number of patients with positive lymph node metastasis who had no lymph node recurrence. gYh is the number of patients with lymph node recurrence. Results: The numbers of patients with colon and rectal cancer were 365 and 147, respectively. The reduction rates of lymph node recurrence in patients with T1, T2, T3, and T4 colon cancer were 100%, 92. 3%, 93. 5%, and 93. 0%, respectively. Those with T1, T2, and T3 rectal cancer were 100%, 90. 9%, and 92. 7%. The reduction rate of lymph node recurrence in patients with T4 rectal cancer could not be calculated, because there was no patient with lymph node metastasis in this population. The rate of lymph node recurrence in patients with positive pericolic lymph node alone was significantly less than that with positive lymph node along the course of major vessels that supply the colon (p = 0. 011). However, there was no difference in the rates of lymph node recurrence among the locations of positive nodes in patients with rectal cancer. Conclusion: When the curative resection with the Japanese standard lymphadenectomy for colorectal cancer was performed, the reduction rates of lymph node recurrence were more than 90% in any T category. The lymph node dissection may be useful in patients with colon cancer who have only pericolic nodal involvement. 55 ABSTRACT BOOK Podium Papers S083 RESULTS FROM PELVIC EXENTERATION FOR LOCALLY ADVANCED COLORECTAL CANCER WITH LYMPH NODE METASTASES, Jin-ichi Hida MD, Takehito Yoshifuji MD, Fumiaki Sugiura MD, Masako Takemoto MD, Takashi Hattori MD, Kazuki Ueda MD, Eizaburou Ishimaru MD, Tadao Tokoro MD, Masayuki Yasutomi MD, Hitoshi Shiozaki MD, Kiyotaka Okuno MD, Department of Surgery, Kinki University School of Medicine, Osaka, Japan Purpose: We examined the survival benefit of pelvic exenteration for locally advanced colorectal cancer with lymph node metastases, because this issue remains controversial. Methods: Medical records of 50 patients who underwent curative pelvic exenteration for colorectal cancer were reviewed retrospectively. Nodal metastases were examined by the clearing method in 29 patients and by the conventional manual method in 21 patients. Results: Invasion to contiguous pelvic organs was present in 40 patients (80%) and absent in 10 patients (20%). Node metastases were present in 33 patients (66%). Operative morbidity and mortality rates were 22% (11 patients) and 6% (3 patients), respectively. Respective 5-year survival rates were 60 and 80% in the groups with and without organ invasion (no significant difference). Fiveyear survival rates in patients with nodal metastases was 54. 6% but was significantly higher, 82. 4%, in patients without nodal metastases. Five-year survival in 28 patients with both organ invasion and nodal metastases was 53. 6%. Conclusions: Longterm survival was afforded by pelvic exenteration for locally advanced colorectal cancer with nodal metastases. S084 PREOPERATIVE VERSUS POSTOPERATIVE CHEMORADIOTHERAPY FOR RECTAL CANCER, Sung Il Choi MD, Jae-Chang Lee MD, Suk-Hwan Lee MD, Kil-Yeon Lee MD, Sung-Eun Hong MD, Kyunghee University Hospital Purpose: Postoperative chemoradiotherapy(XRT)is the recommended standard therapy for patients with locally advanced rectal cancer. In recent years, encouraging results with preoperative XRT have been reported. We compared preoperative XRT with postoperative XRT for locally advanced rectal cancer. Methods: We reviewed 132 rectal cancer patients with curative resection in stage II, III who received either preoperative or postoperative XRT. The preoperative treatment consisted of 5040cGy delivered in fractions of 180cGy per day, five days per week, and fluorouracil, given at a dose of 350mg/m2 during the first, fifth weeks of radiotherapy. Surgery was performed 5weeks after the completion of XRT. One month after surgery, four or five-day cycles of fluorouracil were given. XRT was identical in the postoperative treatment group, except for the presence of levamisol in chemotherapy. The primary end point was disease free survival. Results: Sixty two patient received preoperative XRT, and 70 patients received postoperative XRT. Their clinicopathological factors were no difference in age and sex ratio. The median follow up period were 37. 3, 41. 7 months respectively. Postoperative complications were intestinal obstruction, wound infection, voiding difficulty, bleeding and anastomosis leakage. Postoperative complications were 19 cases(30. 6%) in preoperative XRT and 16 cases(22. 9% ) in postoperative XRT(p=0. 38). The disease free five-year survival rates were 61. 7% and 69. 6% respectively(p=0. 44). The local recurrence rates were 7 cases (11. 3%) in preoperative XRT and 3 cases (4. 2%) in postoperative XRT(p=0. 13). The side effects including acute toxic effects occurred in 41. 9% of the patients in the preoperative treatment group, as compared with 58. 6% of the patients in the postoperative treatment group(p=0. 02). Conclusions: Preoperative XRT, as compared with postoperative XRT, did not show improved local control and disease free survival, but was associated with remarkably decreased toxicity. S085 A QUALITATIVE ANALYSIS OF A FOCUS GROUP DISCUSSION ON PATIENT DECISION MAKING IN CANCER CARE, N Srinivasaiah MD, B Joseph MD, J Gunn MD, J Hartley MD, J R Monson MD, 1. Academic Surgical Unit, University of Hull, Cottingham, UK Introduction: Patient preferences should play an important role when decision making in cancer care. Literature is increasingly demonstrating that surgeons and physicians have divergent preferences for treatment options compared with their patients and with each other. Cancer psychology is an important aspect of 56 ISUCRS XXII BIENNIAL CONGRESS cancer care. Qualitative research is a gateway to explore this. We aim to explore opinions and thoughts among surgical colleagues about “patient decision making in cancer care”. Methods: A pilot focus group discussion among members of the academic surgical unit involving 4 consultants, 3 registrars and 3 research fellows. The discussion was audio-taped and transcribed. Qualitative methodology was adopted for analysis. Thematic analysis using framework approach was done thereby identifying Themes & Outcomes. Results: Themes that emerged are Evidence based clinical practice, Knowledge, Decision making, Patient Information, Risk, Communication, Consent, Socioeconomic factors and Patient empowerment, Outcomes derived are to increase the evidence base, Increase the clinician and patient knowledge, provide adequate information, Decisions to be based on patients best interest, Communicate risk in a understandable manner, Take patients views, knowledge and demands into consideration, Conclusions: Patient decision making in cancer care is slowly evolving, where decisions are not only made taking into account patients views, knowledge and demand but are also driven by them in a minority. Time is a factor and in years to come the patients will play an increased role in their treatments taking into account tradeoffs and risks between survival and quality of life. S086 STARR PROCEDURE FOR OBSTRUCTED DEFAECATION SYNDROME (ODS): 12 MONTH FOLLOW-UP, David G Jayne MD, Oliver Schwandner MD, Leonardo Lenissa MD, Angelo Stuto MD, University of Leeds, Caritas Krankenhaus Str. Josef, Casa di Cura San Pio X, Ospedale S. maria degli Angeli Purpose: A European registry was set-up to determine the short-term safety and efficacy of the STARR procedure for obstructed defaecation syndrome (ODS). 12 month follow-up was completed in February 2008. Methods: STARR registries in Italy, Germany and the UK were designed to allow pooling of results for combined analysis. Recruitment commenced in February 2006. Data collection included a symptom severity score (SSS), obstructed defaecation score (ODS), Cleveland clinic incontinence score, symptom-specific (PAC-QoL) and generic (ED-5Q utility and VAS) quality of life (QoL) scores. STARR was performed using the double stapling PPH-01 technique. All complications were recorded. Data collection was performed at baseline, 6 weeks, and 6 and 12 months. Data management and analysis was performed by an independent body (MedAlliance, Brussels). Results: 1817 patients were recruited and eligible for analysis. 292 (16. 1%) were male. The mean age was 54 yrs (range: 17-92). Defaecating proctography was performed in 92. 7% and showed: rectocele (55%), mucosal prolapse (53. 8%), intussusception (49. 7%), enterocele (5. 5%). Mean operative time was 44mins (range: 15-210). Average length of stay was 3 days (range:1-36). 953 (52%) and 606 (33%) has completed data for analysis at 6 and 12 mths respectively. A significant symptomatic improvement was seen between baseline and 6 mths and maintained at 12 mths (SSS: baseline 15. 2 (95%CI: 14. 9, 15. 5) v’s 12 mths 3. 7 (95%CI: 3. 4, 4. 1), p<0. 001; ODS: baseline 15. 7 (95%CI: 15. 3, 16. 0) v’s 12 mths 6. 1 (95%CI: 5. 2, 7. 0), p<0. 001. This was reflected in a significant improvement in both PAC-QoL and ED-5Q QoL scores at both 6 and 12 mths. Incontinence scores improved from 3. 1 (95%CI: 2. 9, 3. 3) at baseline to 2. 4 (95%CI: 2. 2, 2. 7) at 6 mths and 2. 0 (95%CI: 1. 7, 2. 3) at 12 mths (p<0. 001). 962 minor and major complications were reported in 581 (32%) patients, of which the most frequent were: unexpected pain (7. 7%), urinary retention (6. 3%), bleeding (4. 1%), stapled line complications (3. 5%), sepsis (1. 1%), incontinence (1. 3%). Postoperative defaecatory urgency was reported in 16. 2%. There was 1 rectovaginal fistula and 1 diverting stoma. No mortality was reported. Conclusions: The STARR procedure for ODS is safe and effective and results in a significant improvement in QoL. The benefits appear to be maintained at 12 months. S087 A NOVEL CONCEPT FOR THE SURGICAL ANATOMY OF THE PERINEAL BODY, Ali A Shafik MD, Cairo University Purpose: Perineal body is considered by investigators as a fibromuscular structure that is the site of insertion of perineal muscles. We investigated the hypothesis that perineal body is the site across which perineal muscles pass uninterrupted from one side to the other. ABSTRACT BOOK Podium Papers Methods: Perineal body was studied in 56 cadaveric specimens (46 adults, 10 neonatal deaths) by direct dissection with the help of magnifying loupe, fine surgical instruments, and bright light. Results: Perineal body consisted of three layers: 1) superficial layer, which consisted of fleshy fibers of the external anal sphincter extending across perineal body to become the bulbospongiosus muscle; 2) tendinous extension of superficial transverse perineal muscle crossing perineal body to contralateral superficial transverse perineal muscle, with which it formed a criss-cross pattern; and 3) tendinous fibers of the deep transverse perineal muscle; the fibers crossing perineal body decussated in criss-cross pattern with the contralateral deep transverse perineal muscle. A relation of levator ani or puborectalis muscles to perineal body could not be identified. Conclusions: Perineal body (central perineal tendon) is not the site of insertion of perineal muscles but the site along which muscle fibers of these muscles and the external anal sphincter pass uninterrupted from one side to the other. Such a free passage from one muscle to the other seems to denote a Bdigastric pattern^ for the perineal muscles. Perineal body is subjected to injury or continuous intraabdominal pressure variations, which may eventually result in perineocele, enterocele, or sigmoidocele. [Key words: Perineal muscles; External anal sphincter; Bulbospongiosus; Perineocele; Enterocele; Sigmoidocele] histology. The wounds took 45-90 days for complete healing. The average hospitalization was 3. 4 days. 23 (16%) patients required a further minor procedure during their healing. 7 (4. 9%) patients had recurrence. 3 patients required another surgery, while 4 patients needed 2 more surgeries for complete cure. None of the patients had incontinence to solid stools. Conclusions: Clinical examination provides more information than any investigation; investigations are not always necessary. It is necessary to destroy the anal gland to prevent recurrence. Supralevator tracts can sometimes deter the surgeon, & may lead to an incomplete surgery. They need to be tackled during the primary surgery itself. A close follow up of the wound is needed to ensure optimum healing. A clear understanding of the pathology is the key to a successful surgery. COLORECTAL CANCER AND SURGICAL TECHNIQUES I S088 HYPERBARIC OXYGEN FOR CHRONIC ANAL FISSURE - LONG TERM OUTCOME, N Srinivasaiah MD, Cundall J MD, Laden G, K Chapple, G S Duthie, 1. Academic Surgical Unit, Castle Hill Hospital, Cottingham, UK HU16 5JQ. 2. Hyperbaric Unit, Classic Hospital, Anlaby, Hull, United Kingdom Introduction::Optimal treatment of the patient with a chronic anal fissure (CAF) is unclear. Medical therapy has poor longterm outcome whilst surgery may have significant associated morbidity. We have previously shown, in a small pilot study, that hyperbaric oxygen (HBO) is an effective treatment for CAF. Since long-term outcome is unknown, we investigated a cohort of CAF patients at least 5 years after HBO therapy. Methods: Patients with CAF who had failed both medical and surgical management underwent HBO therapy (fifteen 90 minute treatments of 100% oxygen at 2. 4 atmospheres). Peri-anal symptoms were assessed at least 5 years after HBO therapy using a patient questionnaire. Results: 8 patients (4 male, 4 female, median age 58 [range 2782] years) were identified. Median symptom duration prior to HBO treatment was 2. 5 (IQR 1. 3-4. 6) years. A single patient required further surgery (Rotation flap) and another patient has occasional pain and bleeding. One patient died from un-related causes. The remaining five patients have required no further treatment and are totally asymptomatic. Conclusion: HBO therapy has long-term effectiveness in the treatment of CAF unresponsive to conventional therapy. S090 COMPARISON OF MACROSCOPICAL AND PATHOLOGICAL STUDY BETWEEN PREOPERATIVE RADIOTHERAPY AND RADIOCHEMOTHERAPY FOR ADVANCED RECTAL CANCER, Koji Yasuda MD, Giichiro Tsurita PhD, Tomomitsu Kiyomatsu PhD, Hirokazu Nagawa PhD, The Department of Surgical Oncology, the Graduate School of Medicine, The University of Tokyo Purpose: We studied the macroscopical and pathological effect of preoperative radiotherapy and radiochemotherapy for advanced rectal cancer. Object: This is a retrospective study including patients with preoperative radiotherapy group(RT group, n=82) and preoperative radiochemotherapy group(CRT group, n=41) which are performed radical operation after neoadjuvant therapy. Result: We set an original standard of the macroscopical effect due to neoadjuvant therapy. We classified them into three groups. One group is the macroscopically CR group which satisfy with that the reduction rate is over 75% by Barium enema examination and the circumference of tumor is completely flatten by endoscopic examination. The second group is the macroscopically small CR group which satisfy with one of the two item above. The third group is except the macroscopically CR and small CR group. Result: The cases of the macroscopically CR were 6 cases(7. 3%) of the RT group and 7 cases(17. 1%) of the CRT group. The case of the macroscopically small CR were 10 cases(12. 2%) of the RT group and 8 cases(19. 5%) of the CRT group. The grade 3 cases in the macroscopically CR were 2 cases(33. 3%) of the RT group and 4 cases(57. 1%) of the CRT group. And all cases of the macroscopically CR and small CR group had the pathological effect over the grade 2. Conclusion: The CRT group had a tendency to have more effective macroscopically and pathologically . And there were interrelation macroscopical effect between pathological effect. S089 A RETROSPECTIVE STUDY OF 144 CASES OF RECURRENT & COMPLEX FISTULA IN ANO, Parvez Sheikh, P. N. Joshi, Charak Clinic, Mumbai, India Purpose: To identify the causes of recurrence & device successful management strategies with minimal complications to treat fistula in ano. Methods: 144 cases of recurrent cryptoglandular fistula in ano were operated over a 5year period in a colorectal referral centre. Most of the cases were complex fistulae with multiple tracts & external openings as widespread as anterior abdominal wall & thigh. All the patients had undergone 1-5 surgeries in the past. No special investigations were ordered, though some patients were referred after an MRI. During the surgical procedure, the cause of recurrence was recorded. The procedures done were fistulotomy, fistulectomy, coring out & endoanal advancement flap. The causative anal gland was always destroyed. Any large divided muscle mass was primarily sutured. No seton, fibrin glue or anal plug was used. No colostomy was created. All the patients were followed up closely till complete healing was established. Results: 29 patients (20%) had more than 1 cause for recurrence. The common causes for recurrence were- anal gland was left behind in 94 (65%), supralevator tract in 34 (24%), residual tracts in 43 (30%) & 2 (1. 4%) patients had tuberculosis on S091 THE SIGNIFICANCE OF TUMOR VOLUME REDUCTION RATE AND DIGITAL RECTAL EXAMINATION AS TUMOR RESPONSE PREDICTIVE MARKERS IN THE PATIENTS WITH LOCALLY ADVANCED RECTAL CANCER AFTER PREOPERATIVE CHEMORADIATION, Jung Hyun Kang MD, Jeong Yoen Kim MD, Nam Kyu Kim MD, Seung Kook Sohn MD, Chang Hwan Cho MD, Byung Soh Min MD, Yonsei University Health System, Seoul, Korea Background: Preoperative chemoradiation (preop-CRT) is accepted as a standard treatment for locally advanced rectal cancer enhancing sphincter preservation and local control. It spans, however, a wide spectrum of tumor response from complete disappearance of cancer (pCR) to progression of the disease. An accurate prediction of tumor response after preopCRT is essential to understand patients¡¯ prognosis and to plan treatment strategies. Thus, the aim of this study is to evaluate the significance of tumor volume reduction rate (TVRR) and digital rectal examination (DRE) as tumor response predictive markers in the patients with locally advanced rectal cancer after preoperative chemoradiation. Patients and Methods: we prospectively enrolled 25 patients with biopsy-confirmed rectal cancer. All patients underwent preoperative chemoradiation irradiating 5040 www.isucrs.org/ 57 ABSTRACT BOOK Podium Papers cGy for 5 weeks. Concurrent chemotherapy was performed using either 5-FU/LV or TS-1/CPT-11 regimen. DRE and rectal MRI was performed initially and 5-6 weeks after preop-CRT. TVRR was calculated using 3D MR volumetery. Total mesorectal excision was given 6 weeks after preop-CRT to all patients and tumor response grade (TRG) was scored as suggested by Mandard et al. The correlation between histopathologic parameters (TRG and T-/N-downstaging) and clinical parameters (TVRR and DRE) was analyzed. Results: The mean age of the enrolled patients was 56. 3 years. TRG1 was observed in 7 patients, TRG2 in 6, TRG3 in 5 and TRG4 in 5 respectively. Pathologic stage was ypT0 in 7 patients, ypT1 in 1, ypT2 in 8, ypT3 in 8, and ypT4 in 1, respectively and ypN0 in 23 ypN1 in 2 patients. DRE-responder (either disappearance of mass or becoming mobile on DRE) was 68%(N=17/25). The mean TVRR was 65. 8%. TRG was simplified into complete regression (TRG1) and partial regression (TRG2-5). DRE-responder was significantly associated with T-downstaging (p=0. 037) but it was not associated with TRG and N-downstaging (p=0. 819; p=0. 356). TVRR was significantly correlated with TRG (p=0. 045), but not with T- and N-downstaging (p=0. 356; p=0. 702). Conclusions: The results from the current study suggested that TVRR from 3D MR volumetery and DRE by expert surgeons may have significance as predictive markers for tumor response after preop-CRT for locally advanced rectal cancer. S092 ROLE OF ADJUVANT RADIOTHERAPY AFTER TOTAL MESORECTAL EXCISION IN PATIENT WITH STAGE II RECTAL CANCER, JinSoo Kim MD, NamKyu Kim MD, ByungSo Min MD, Hyuk Hur MD, ChoongBae Ahn MD, KiChang Keum MD, SeungKook Sohn MD, JangHwan Cho MD, Department of Surgery, Medical Oncology, Radiation Oncology, Yonsei University College of Medicine, Seoul, Korea Introduction: Because the curative rectal surgery is performed in narrow and complicated anatomic pelvic structure, tumor cells can be implanted easily during the surgery. In result, local recurrence is major problem in rectal cancer. In the 1990s, several randomized trials reported the benefit of postoperative adjuvant chemoradiotherapy (CRT) for low local recurrence. CRT became the standard treatment for postoperative adjuvant therapy. In the era of total mesorectal excisioin (TME), it has improved local recurrence markedly. Therefore the benefit of adjuvant CRT associated with TME is under debate especially in patients with stage II rectal cancer. The aim of this study was to evaluate adjuvant CRT effect for local recurrence, survival, and radiation complications in stage II rectal cancer patients who underwent TME. Patients and Methods: Between 1989 and 2004, patients with stage II rectal cancer underwent adjuvant chemotherapy (CT, n=32) and CRT (n=121) following TME were enrolled retrospectively. Both two groups received 5-fluorourcil and leucovorin based chemotherapy. We analyzed clinicopathologic data, recurrence rate, and survival between the two groups. Complications associated with radiation were also examined. Results: There were no differences in clinicopathologic data such as age, sex, operative method, tumor size, number of retrieved lymph node, tumor differentiation between two groups. With a median follow-up of 72. 1 months, one patient (3. 1%) had local recurrence in the CT group and 12 patients (9. 9%) in the CRT group. However, there was no significant difference (P=0. 303). The 3-year and 5-year cancer specific survival showed 96. 8%, 86. 8% in the CT group and 89. 1%, 80. 9% in the CRT group (P=0. 854). Complications associated with radiation were proctocolitis (5. 0%), stricture (2. 5%), enteritis (2. 5%), rectovaginal fistula (1. 7%), and vaginal dryness (0. 8%). Conclusion: Postoperative CT and CRT following TME in stage II rectal cancer resulted in comparable recurrence and survival rates. Additionally CRT group had relatively high complications. These findings suggest that postoperative radiation is not necessary in patients with stage II rectal cancer if TME was performed. However, randomized prospective trials are warranted to support this suggestion. S093 WITHDRAWN S094 ENDOSCOPIC SUBMUCOSAL DISSECTION FOR COLORECTAL NEOPLASIA: EARLY EXPERIENCES 94 CASES Eun-jung Lee MD, JaeBum Lee MD, Suk Hee Lee MD, Do Sun Kim MD, Doo Han Lee MD, Eui Gon Youk MD, Daehang Hospital 58 ISUCRS XXII BIENNIAL CONGRESS Purpose: In the endoscopic treatment of a tumor, en bloc resection is one of the basic principles for an accurate pathologic diagnosis. Endoscoic Mucosal Resection(EMR) is a useful therapeutic technique for colorectal tumors. However, the physical size of the snare limits en bloc resection of colorectal neoplasia larger than 20 mm. Endoscopic Submucosal Dissection (ESD), a recently introduced endoscopic technique, makes it possible to perform an en bloc resection of a lesion, which could not be carried out by EMR. The aim of this study was to report the early experiences of colorectal ESD performed in our hospital. Methods: Between October 2006 and January 2008, ninety-four consecutive colorectal neoplasia in 94 patients were enrolled. After submucosal injection with hyaluronic acid, mucosal incision was done around the tumors and submucosal dissection under the tumors was made by cutting devices. The clinical outcomes were investigated. Results: Mean size of resected tumors was 24. 1(10-45)mm. Overall endoscopic and pathologic en bloc resection rates were 86. 2%(81/94) and 85. 1%(80/94) respectively. Perforation occurred in twelve cases out of ninety-four(12. 8%). In nine patients, perforation was managed by endoscopic clipping without salvage surgery and the other three patients received laparoscopic operation. Mean procedure time was 70. 1(15-180) min. Pathologic examination showed 57 benign neoplasms(60. 6%) and 37 adenocarcinomas(39. 4%). Three patients with sm 2 invasion and one patient of sm1 invasion with unfavorable pathologic findings received additional laparoscopic surgery. Conclusion: ESD is a technically challenging procedure with a substantial risk of perforation and long procedure time. But ESD has an advantage in en bloc resection of large colorectal tumors. As experience with the technique accumulates, ESD will gradually replace piecemeal EMR and surgery in the majority of cases. S095 SHOULD COMPLETELY INTRACORPOREAL ANASTOMOSIS BE CONSIDERED IN OBESE PATIENTS UNDERGOING LAPAROSCOPIC COLECTOMY FOR BENIGN OR MALIGNANT DISEASE OF THE COLON?, I Raftopoulos MD, R Bergamaschi MD, Saint Francis Hospital and Medical Center, Hartford, Connecticut Purpose: This study was performed to assess the outcome of laparoscopic colectomy with completely intracorporeal anastomosis (LCIA) in obese and nonobese patients. Methods: 45 consecutive patients who underwent LCIA for benign or malignant disease of the colon between 11/03 and 12/05 were prospectively reviewed. Colon mobilization, bowel and mesenteric division, and anastomosis were performed intracorporeally without exteriorization until specimen extraction at end of procedure. Body mass index (BMI) >30 kg/m2 defined obesity. Incision length was measured immediately after wound closure. Continuous and categorical variables were compared with Student’s t-test and chi-square, respectively. P<0. 05 was considered significant. Results: There were 24 (53. 3%) males and 21 (46. 7%) females with a mean age of 67. 2 (46-84) years. Of the 45 LCIA, 10 (22. 3%) involved the left colon and 35 (77. 7%) the right colon. Mean BMI was 26. 7 (15. 5-37. 9) kg/m2; 13 (28. 9%) patients were obese. One (2. 2%) obese patient was converted to a laparoscopic-assisted right hemicolectomy. Preoperative localization of lesion with endoscopic India ink injection was used in 24 cases (53. 3%), and the tattoo was identified laparoscopically in all cases. Mean operative time (OT), estimated blood loss (EBL), and length of stay (LOS) were 217. 9 (110-420) min, 82. 3 (50-250) ml, and 4. 9 (2-11) days, respectively. There was significant reduction in OT (181. 1 vs. 253 min, p=0. 0003) in the last 22 cases. Mean lengths of larger incision (extraction site) and sum of all port incisions were 3. 9 (2. 5-8) cm ABSTRACT BOOK Podium Papers and 7. 2 (5. 5-10. 4) cm, respectively. Complications occurred in 8/45 (17. 8%) patients. Leak, obstruction, reoperation, pulmonary complication, and mortality rates were zero. A 5 cm tumor-free margin was accomplished in all patients with benign or malignant tumors without need for additional resections. Mean number of harvested lymph nodes per specimen was 11. 3 (3-24). Obesity had no significant effect on OT (obese: 231. 5 vs. nonobese: 212. 6 min), incision length (3. 9 vs. 4. 0 cm), number of ports used (4. 2 vs. 4. 2), EBL (100 vs. 75. 6 ml), complications (16. 7 vs. 18. 75%), LOS (4. 9 vs. 5. 0 days), or number of harvested lymph nodes per specimen (12. 4 vs. 10. 9). At mean follow up of 5 (1-18) months, there were no port-site hernias, and of patients with malignancy, none developed port-site metastases. Conclusion: Smaller incisions achieved by a completely intracorporeal approach may decrease risk of pulmonary complications and port-site hernias. S096 KSHAAR-SOOTRA (HERBAL MEDICATED THREAD) IN THE MANAGEMENT OF RECURRENT FISTULA-IN-ANO, Harshit S Shah MD, Sejal H Shah MD, Anand Kshaar Sootra Clinic As you know that the anal fistula is a notorious disease due to its anatomical situation and recurrences even with skilled surgeons. Its location and tendency to recur many a times brings discredit frustration to the surgical fraternity. The condition of complicated, recurrent and high fistula-in-ano, although not a major surgical task; but always remains a nagging issue not only to the patient but to the surgeon as well. The present method of KSHAAR-SOOTRA treatment in anal fistula has been found efficacious and have been accepted by many countries in world. This method is described in ancient Indian surgical science. This research paper aimed to evaluate the following points. 1. Healing time of the fistulous track. 2. Recurrence rate of fistula. 3. Side effect and complications. 4. Time of HospitalizationKSHAAR-SOOTRA was inserted in the O. P. D. The patient was placed in the lithotomic position and after aseptic preparation of the part probing was done under local anesthesia. With specially designed probes the sterile silk thread was passed through carefully in the fistulous track; tied and left in situ (Primary threading). A week later the silk thread was replaced by KSHAAR-SOOTRA by the railroading technique and tied snugly outside the anal orifice. Among the 106 patient who completed treatment, 7 patients failed to attend follow-up schedule. Remaining 99 patients completed one year follow-up. Among these recurrence rate was 4% in 52 patient treated with KSHAAR SOOTRA as compared to 13% of 47 in the Surgery series. The initial length of fistulous track was recorded by measuring the length of the silk thread. After insertion of KSHAAR-SOOTRA, the patient was sent home and advised to continue his normal routine work. The thread was changed at weekly intervals till the thread fell out spontaneously and the track healed. S097 PELVIC EXENTERATION WITH RECONSTRUCTION OF URINARY AND ANAL SPHINCTER FUNCTIONS FOR PATIENTS OF COLORECTAL CANCERS NORMALLY REQUIRING TPE, K Koda MD, H Yasuda MD, M Suzuki MD, M Yamazaki MD, T Tezuka MD, C Kosugi MD, R Higuchi MD, M Sugimoto MD, Y Yagawa MD, H Tsuchiya MD, Teikyo University Chiba Medical Center Purpose: Total pelvic exenteration (TPE) is a formidable procedure involving double stoma for faecal and urinary excretion, which degrades patient’s quality of life. We presented a novel reconstruction method for patients normally requiring TPE and evaluated their long term outcome. Method: Tumours were removed en bloc with internal iliac artery and lateral lymph nodes. The urethra was transacted at the urogenital diaphragm, and the rectum at the anal canal. An ileal neobladder was constructed and anastomosed with urethra. A colo-anal anastomosis was performed by double-stapling technique. We usually set major omentum between colo-anal and neobladder-urethral anastomoses so as to prevent a fistula formation between the two anastomoses. A transgastric ileus tube was used as an intestinal stent to prevent ileus. Results: Since 1998, we have performed this operation to 13 patients (12 males, 1 female) among 27 patients requiring TPE. Twelve of them had a primary colorectal cancers and 1 pelvic recurrence. There was no operation-related death. Median operation time was 650min [540-840min], and www.isucrs.org/ blood loss was 1200gram [600-6300gram]. Histological invasion to urine bladder, seminal vesicle, or prostate was seen in 10 patients out of 13 treated; massive inflammation or abscess formation was noted in the remaining 3 cases. No patients had bloodborne metastases at the time of operation; 9 patients showed lymph node metastasis. Out of 13 patients treated, 11 patients remain alive without recurrence at the median follow up period of 1699 days [302 - 3495 days]. Recurrent diseases were seen in 2 patients: one died of the disseminated disease 8 months after the operation; another had metachronous lung metastasis which was surgically removed 5 years ago. Faecal continence was preserved in 11 patients whose diverting colostomies were closed. All 13 patients were able to void urine spontaneously with daytime continence. All but one who died of the disease were mobile in the community. Conclusion: Stomaless pelvic exenteration may be considered for patients normally requiring TPE. Long term postoperative quality of life was fair. COLORECTAL CANCER AND SURGICAL TECHNIQUES II S098 THE PROGNOSTIC SIGNIFICANCE OF ERBB FAMILY EXPRESSIONS IN PATIENTS WITH CURATIVE RESECTION FOR COLORECTAL CANCERS, Byung-Wook Min, Seong-Soo Kim, Sang-Hee Kang, Jun-Won Um, Department of Surgery, Korea University College of Medicine, Seoul, Korea Background and Purpose: The ErbB family; ErbB1(EGFR), ErbB2(Her2/neu), ErbB3, and ErbB4, is associated to cell growth, differentiation, cell survival, apoptosis, cell cycle progression, angiogenesis, drug and radiation sensitivity. In this study, the expression of ErbB family of colorectal cancer specimen were investigated to determined the correlations between the clinicopathologic characteristics and the expression of ErbB family in the curative resection for colorectal cancers, icluding cancer specific survival. Patients and Method: One hundred ninety six patients who underwent the curative surgery for colorectal cancers from January 1997 to December 2000 at Korea University Medical Center were enrolled in this study. The tumor and normal samples were obtained from paraffinembedded blocks of specimen and studied by tissue microarray. Immunohistochemical stains for ErbB family were performed for each specimen. The clinical relationship between the expression of ErbB family and clinicopatholoic characteristics were anlyzed. Results: There was no significant relationship of the expression of ErbB family to clinicopathologic characteristics. However in respect to survival analysis, 5-year survival rates of patients with the positive expression of ErbB1 was lower than those of the negative expression of ErbB1(65% vs. 92%, p <0. 05). Moreover 5-year survival rate of the positive expression of ErbB1 was lower in well differentiation subgroup(70% vs. 98%), node negative subgroup(90% vs. 95%), node poitive subgroup(40% vs. 78%), and T3 subgroup(65% vs. 90%). Conclusion: This study did not show the relations of ErbB family expression with the clinicopathologic characteristics. However the positive ErbB1 expression of colorctal cancer was one of poor prognostic factors in patients with colorectal cancer. S099 BRAIN METASTASES FROM COLORECTAL CANCER, Ji-Hoon Kim MD, Jae-Im Lee MD, Hyung-Jin Kim MD, Sang-Chul Lee MD, Yoon-Suk Lee MD, Won-Kyung Kang MD, Jong-Kyung Park MD, Chang-Hyeok Ahn, Seong-Taek Oh MD, Department of Surgery, The Catholic University of Korea Purpose: Brain metastasis is infrequent in colorectal cancer patients. And the prognosis of brain metastasis is known to be poor. The purpose of this study is to analyze the survival and the prognostic factors in patients with brain metastasis from colorectal cancer. Methods: Between 1997 and 2006, we retrospectively identified 39 patients with brain metastasis from colorectal cancer and who were survived longer than 1 month. The data were collected with regard to patient characteristics, location and stage of primary tumor, extent and location of metastatic diseases and the type of treatment. Results: The mean age of the 16 women and 23 men was 59 years (40-81). Rectum was more frequent primary tumor site than colon (22 vs 17). The stages of primary tumor were stage 2 in 2 cases, 3 in 17 cases and 4 in 9 cases. The mean interval from the time of primary 59 ABSTRACT BOOK Podium Papers cancer surgery to the diagnosis of brain metastases was 32. 3 months. Most of the patients (87. 2%) had pulmonary metastases before brain metastasis and brain was the only metastatic site in only one patient. The most frequent symptoms were weakness (18/39), headache (11/39) and dysarthria (4/39). Lesions were solitary in 22 cases, unilateral in 26 cases, and located in cerebral in 26 cases. Overall mean survival was 7. 95 months; the 1-year and 2-year survival rates were 21. 76% and 9. 07%, respectively. Survival was not affected by gender and age, location or stage of the primary tumor, and size or location of metastatic disease. But serum CEA level greater than 5 ng/ml (p=0. 0082) and multiple metastatic lesions in brain (p=0. 0302) were the poor prognostic factors. And the mean survival time after the diagnosis of brain metastasis was longer significantly in patients who underwent surgical excision (18. 70 months) than who were treated with whole brain irradiation, sterotatic radiosurgery, and conservative care (6. 42, 6. 34 and 2. 78 months) (p=0. 0039). Conclusion: The results of the present study indicate that aggressive surgical resection in patients with brain metastases from colorectal cancer may increase the survival. And analysis of prognostic factors in these patients shows that multiple metastatic lesions in brain and serum CEA level greater than 5 ng/ml were also associated with a poorer survival. S100 COLORECTAL SURGERY IN CIRRHOTIC PATIENTS. ASSESSMENT OF OPERATIVE MORTALITY AND MORTALITY, J-P Arnaud MD, K Meunier MD, S HennekinneMucci MD, R Azoulay MD, A Hamy MD, Department of Visceral Surgery, Chu-Angers, France Surgery for colorectal diseases has an elevated morbidity. For cirrhotic patients, there is a high risk of mortality and morbidity following surgery. The aim of this study was to evaluate morbidity, mortality and prognostic factors regarding colorectal surgery in cirrhotic patients. From 1993 to 2006, 41 cirrhotic patients who underwent 43 colorectal procedures were included. Both univariate and multivariate analyses were carried out so as to identify those variables influencing morbidity and mortality. Postoperative morbidity was 77% (33/43). Postoperative mortality was 26% (11/43) among which 6 patients (54%) underwent emergency surgery. In this study, four factors influenced mortality in the univariate analysis : emergency (p<0. 05), postoperative complications (p<0. 04), postoperative infections (p<0. 01) and total colectomy procedures (p<0. 02). In the multivariate analysis, the only factor influencing mortality was postoperative infection (p<0. 04). The only factor influencing morbidity was the existence of preoperative ascites (p<0. 04). Colorectal surgery for cirrhotic patients is at high risk in terms of morbidity and mortality. The prognosis is linked to the septic, urgent and extensive nature of surgery and the ascitic decompensation of cirrhosis. An improvement in the results can be achieved through better selection and preparation of patients. S101 ABDOMINAL STAPLED SIDE-TO-END ANASTOMOSIS (BAKER TYPE) IN LOW AND HIGH ANTERIOR RESECTION: EXPERIENCE AND RESULTS IN 96 CONSECUTIVE PATIENTS AT A REGIONAL GENERAL HOSPITAL IN JAPAN, Ichiro Nakada MD, T. Satani MD, T. Kasuga MD, Y. Watanabe MD, T. Tabuchi MD, Department of Surgery, Tokyo Medical University Kasumigaura Hospital Purpose: The technique of trans-anally introducing a circular stapled device to accomplish colorectal anastomosis has been widely used. However, the widespread popularity of this technique may have created the potential of anal sphincter injury during trans-anal insertion of the anastomosing stapler. Thus, to avoid the risk of anal sphincter injury during anal manipulation, we have been performing an abdominal approach, namely abdominal stapled side-to-end anastomosis (ASSEA) using a Purstring and premium curved EEA stapler in low and high anterior resection. This study will present our experience and results of consecutive resections. Methods: ASSEA following a resection of the rectum for carcinomas was consecutively performed between October 1998 and October 2006. Age, gender, pre-operative anal function, the TNM classification by the UICC rules, postoperative morbidity, mortality, anal function, and bowel frequency were evaluated. Results: Ninety-six consecutive patients underwent a resection of the rectum with ASSEA. The mean age was 65. 5 60 ISUCRS XXII BIENNIAL CONGRESS years (range 26-96 years). There were 57 men and 39 women. There were five (5. 2%) clinical anastomotic leakages in the cases studied. Anastomosis that was located above the peritoneal reflection leaked in two (3. 6%) of 56 cases, while anastomosis below the peritoneal reflection leaked in three (7. 5%) of 40 cases. A diverting stoma was performed in five (12. 5%) of the 40 cases with low anastomosis. During the same period, fourteen abdominoperineal excisions (25. 9%) were performed because of very advanced carcinomas. Postoperative anal function was stable without soiling or fecal leakage. Bowel frequency two months after surgery was less than four times a day in all 84 patients. There was no postoperative mortality related to the anastomosis. Conclusion: Abdominal stapled side-to-end anastomosis (Baker type) was found to be a safe and relatively easy method in both low and high anterior resection in association with a good quality of life. S102 DOES TOTAL MESORECTAL EXCISION REQUIRE A LEARNING CURVE? ANALYSIS FROM DATABASE OF SINGLE SURGEON’S EXPERIENCE, Seung Yeop Oh MD, Ok Joo Paek MD, Kwang Wook Suh MD, Department of Surgery, Ajou University School of Medicine Purpose: Total mesorectal excision (TME) has been regarded as a standard treatment for the rectal cancer. However, grasp of technical adequacy is also formidable. This study was conducted to determine whether TME requires a learning curve to grasp a technical expertise. Methods: This was a retrospective analysis of 195 patients with true rectal cancer who underwent TME with curative intention between August 1998 and December 2003 in Ajou University Hospital. To examine if a learning curve for proper TME procedure was necessary, patients were divided into four groups: group 1 included 50 consecutive patients from August 1998. Group 2, 3, and 4 included next 50 consecutive patients, respectively. Local recurrence(LR) rate was compared between groups. To examine the learning curve was a meaningful prognostic factor, univariate and multivariate analyses were conducted. Results: Overall LR rate was 11. 3%. The LR was 20% (group 1), 14% (group 2), 8% (group 3) and 2. 2% (group 4), respectively. The cumulative risk of LR at 60 months following initial operation was 23. 6%, 15. 9%, 8. 7% and 2. 9%, respectively. LR was significantly higher in group 1 when compared with the other groups (P=0. 002). Between group 2, 3 and 4, there was no significant difference in LR. It was found that a learning curve in performing adequate TME is necessary, and experience of at least 50 cases is the critical point to grasp technical adequacy. In univariate analysis, lymph node metastasis, early period of learning curve (group 1), and depth of tumor invasion were significant prognostic factors. In multivariate analysis, lymph node metastasis and early period of learning curve still proved significant. Since the technical bias was identified, risk factors for LR could be different when the whole study population was separated as to learning curve. In subset analysis, tumor size, location, regional lymph node metastasis, and operative time proved as significant risk factors in the inadequate TME group (group 1, N=50). Lymph node metastasis and depth of primary tumor invasion were significant in the adequate TME group(groups 2, 3, 4, N=144). However, the regional lymph node metastasis was constantly significant in both adequate and inadequate TME groups. Conclusion: Even though the principle of TME is strictly obeyed, a learning curve is necessary to grasp a technical expertise and trainees need to perform more than fifty cases to get learning curve. Lymph node metastasis is the most important prognostic factor and the technical adequacy is also an independent prognsotic factor. Vigorous training and assessment of each surgeon are important to reach the highest point of learning curve and further multinstitutional study is warranted. S103 DE-EPITHELIALIZED PUDENDAL-THIGH(SINGAPOUR)-FLAP FOR THE TREATMENT OF LOW RECTO(ANO-) VAGINAL FISTULAE, Johann Pfeifer MD, Stephan Spendel* MD, Michael Schintler* MD, Department of General Surgery, *Department of Plastic Surgery Introduction: The causative effect of a low recto- and anovaginal fistula is often an obstetric injury. The surgical problem is that the length of the fistula is usually very short and simple closure leads often to recurrence. On the other side patients are often young, still sexually active and may have dyspareunia if a thick ABSTRACT BOOK Podium Papers well perfused tissue flap (like the gracilis muscle) is interposed into the rectovaginal septum to avoid fistula recurrence. Patients and Methods: All consecutive patients with a low anovaginal or recto-vaginal fistula are included into the study. The first operative step is to open the rectovaginal space and to close the fistula on the rectal and vaginal side. Then a 12cm x 4 cm long skin/subcutis flap with its nutritional vessels is mobilized. Part of the flap must be de-epithelialized and then rotated into the rectovaginal space. Finally with some absorbable sutures the flap is held in place and the perineum closed. A protective stoma is often not nescessary. Results: From June 2006 to December 2007 5 patients with a low anorectal or recto-vaginal fistula have been operated with this method. Three patients had together 8 failed local repairs (even one patient had had already a stoma). Fistulae in four patients healed without any complications (follow-up 1- 15 months), in one patient the operation was not successful. This patient had an early recurrence probably due to improper fixation of the flap. In the acute situation a stoma was performed and the flap re-fixated. This patient has currently still the stoma (waiting for take down) but clinically the fistula has healed. Conclusion: Low recto-vaginal or ano-vaginal fistulae can be treated in most cases successfully with the de-epithelialized pudendal-thigh(Singapour)-flap. S104 ABDOMINAL WALL COMPONENTS SEPARATION TECHNIQUE FOR CLOSURE OF VENTRAL DEFECTS INITIAL EXPERIENCE AND LESSONS LEARNT, Bruce Waxman MSc, S Jassal, L Dandie, D Goodall-Wilson, M Fisher, Dandenong Hospital, Southern Health Purpose: The Abdominal Wall Components Separation Technique (AWCST), allows closure of ventral defects by transposition of the abdominal wall muscle(1, 2). The aim of this audit of our initial experience was to evaluate the technique for repairing defects after removal of infected mesh or for uncomplicated incisional hernia. Methodology: A prospective audit was conducted on the initial experience of 18 consecutive patients having AWCST, under the care of the Colorectal Unit, Dandenong Hospital, for the twelve month period from August 2006 to July 2007. Results: Of the 18 patients, 5 had infected mesh and 13 had large incisional hernias. The median follow up was 96 days range 25 - 360 days. Significant wound infections occurred in 5 patients requiring re-operation. In all 5 the abdominal wall repair remained in tact. One patient has developed a recurrent incisional hernia. Conclusion: AWCST is a useful procedure for the closure of large abdominal wall defects, and may avoid the use of mesh. We recommend avoiding primary skin closure after removing infected mesh and follow the principle of delayed primary closure. No specific conclusions can be made from this small series with a short follow up, but the technique has merit and requires further evaluation. Reference: 1.

S105 TRANSACRAL RESECTION WITH SACRECTOMY IN THE ERA OF TEM, Bong Hwa Lee MD, Hyoung-Chul Park MD, Soo Hyung Kim MD, Sung Wook Cho MD, Taeik Um MD, Hallym University College of Medicine, Seoul, South Korea Background: Local resection of presacral and rectal mass was a good option to avoid morbidity relevant to the major operation. The aim of this study is to describe the technique and experience of removal of presacral and rectal mass through trans-sacral route with midline incision and lower sacrectomy (S4, S5). Methods: We present an approach for local excisions of 21 cases of lesions. The diagnoses were large epidermal cyst, GIST, high grade adenoma and early cancers in mid rectum. Results: Epidural anesthesia was appropriate to perform the whole procedures. There was one case of recto-cutaneous fistula among 21 cases as a postoperative complication. In one case of submucosal cancers, multiple metastasis occurred in 24 months without local recurrence. Comments: In our experience. trans-sacral resection with lower sacrectomy is a good option which provides wide and direct surgical exposure for the removal of presacral mass. Good bowel preparation was mandatory. www.isucrs.org/ Final Pathology of Specimen after TSR (n=21) Specimen Pathology Operation epidermal cyst Excision adenocarcinoma submucosa FT excision proper muscle FT excision GIST (1) FT excision Others (3) FT excision FT excsion = full thickness rectal wall excision Follow-up no recur mets in 1/2 no recur no recur COLORECTAL CANCER AND LAPAROSCOPIC SURGERY I S106 YOUNGER AGE AND MORE DISTAL CANCERS CHANGE IN THE EPIDEMIOLOGY OF COLORECTAL CANCER AND IMPLICATION FOR SCREENING, Bruce Waxman MSc, Mikhail Fisher, Dandenong Hospital, Southern Health Purpose: To determine whether pattern of patients presenting with colorectal cancer (CRC) in the last 2 years differs significantly from that previously reported. Methodology: We examined demographic and pathological characteristics of 145 consecutive CRC patients treated in our institution in calendar years 200607. Comparisons were made with data on 12536 CRC patients obtained from The Australasian Association of Cancer Registries (AACR) for the year 2003, most recent available. Results: In our series distribution of colon, rectal and rectosigmoid cancers was 40%, 35. 0% and 24. 8% respectively, which differs significantly (p<0. 01) from 64. 9%, 26. 9% and 8. 2% in the AACR data. Our cohort of patients was significantly younger: mean age 65. 4 ± 12. 1 vs 69. 5 ± 12. 3 years (p<0. 001). In both groups rectal cancer patients were the youngest: mean 62. 4 ± 11. 8 vs 67. 2 ±12. 7 years (p <0. 001). These differences were most pronounced amongst females: 63. 0 ± 12. 7 vs 70. 3 ± 13. 0 years (p<0. 001) overall and 59. 9 ± 9. 5 vs 67. 8 ± 13. 8 years (p<0. 001) in the rectal cancer subgroup. Furthermore, we treated significantly higher proportion of patients <55 years of age (20% vs 13%; p = 0. 018) or <60 years (33. 1% vs 21. 5%; p = 0. 001). Conclusions: Our small series shows a more distal distribution for CRCs from that seen previously in the Australian population. Of greatest concern is a higher proportion of patients aged <60 (33%), especially females (41%). Younger patients are also more likely to have more aggressive and advanced cancers. These findings may have important implications for refining screening strategies and on demand for radiotherapy services. S107 INFLAMMATION-BASED PROGNOSTIC SCORE PREDICTS POSTOPERATIVE OUTCOME IN PATIENTS WITH LIVER METASTASES FROM COLORECTAL CANCER, Mitsuru Ishizuka MD, Tokihiko Sawada MD, Mitsugi Shimoda MD, Junji Kita MD, Kyuu Rokkaku MD, Masato Kato MD, Keiichi Kubota MD, Department of Gastroenterological Surgery, Dokkyo Medical University Background: Recent studies have revealed that the Glasgow prognostic score (GPS), an inflammation-based prognostic score that includes only C-reactive protein (CRP) and albumin, is a useful tool for predicting postoperative outcome in cancer patients. However, few studies have investigated the GPS in patients with liver metastases from colorectal cancer (LM-CRC). Objective: To demonstrate the significance of the GPS for postoperative prognostication of patients with LM-CRC. Methods: The GPS was calculated as follows: patients with both an elevated level of CRP (>10 mg/l) and hypoalbuminemia (Alb <35 g/l) were allocated a score of 2, and patients showing one or neither of these blood chemistry abnormalities were allocated a score of 1 or 0, respectively. Prognostic significance was analyzed by KaplanMeier, univariate and multivariate analyses. Results: Ninetythree patients were evaluated retrospectively. Kaplan-Meier analysis and log rank test revealed that a higher GPS predicted a higher risk of postoperative mortality (P <0. 0001). Univariate analysis revealed that sex (P = 0. 0334), number of hepatectomy (P = 0. 0427), number of tumors (P = 0. 0206), synchronous lung metastasis (P = 0. 0275) and CRP (P = 0. 0477) were associated with postoperative mortality. Multivariate analysis revealed that times of hepatectomy (odds ratio, 0. 313; 95% C. I. , 0. 108-0. 906; P = 0. 0322), number of tumors (odds ratio, 0. 348; 95% C. I. , 0. 61 ABSTRACT BOOK Podium Papers 128-0. 943; P = 0. 0379), synchronous lung metastasis (odds ratio, 0. 281; 95% C. I. , 0. 088-0. 895; P = 0. 0318) and CRP (odds ratio, 1. 792; 95% C. I. , 1. 119-2. 870; P = 0. 0153) were associated with postoperative mortality. Conclusions: GPS, especially CRP, is considered an important predictor of postoperative mortality in patients with LM-CRC. S108 LAPAROSCOPIC VS. OPEN REVERSAL OF HARTMANN’S FOR DIVERTICULITIS, B Safar MD, S Shawki, MD, H Wang MD, S Cera MD, D Efron MD, D Sands MD, E Weiss MD, A Vernava MD, J Nogueras MD, S Wexner MD, Cleveland Clinic Florida Purpose: Hartmann reversal can be a technically challenging operation associated with significant morbidity. Laparoscopy has been associated with some definitive short term advantages and possibly long term advantages. The aim of this study was to determine whether laparoscopic Hartmann reversal provides any advantages as compared with the open technique. Methods: After IRB approval, patients who underwent laparoscopic Hartmann reversal for diverticulitis were identified in our prospectively collected database. These patients were case matched by age, gender, body mass index and diagnosis to control patients who underwent the same operation through an open technique. Intraoperative data and postoperative outcomes were recorded. Results: Thirty one laparoscopic Hartmann reversals were identified, 27 of which were performed for diverticulitis. These were case matched with 27 open Hartmann reversal operations for diverticulitis. The laparoscopic group (Mean age, 63; 52% Female; Mean BMI 27) were similar to the open group (Mean age, 62; 52% Female; Mean BMI 27). The conversion rate in the laparoscopic group was 37%; most conversions were due to failure to progress as a result of dense adhesions. Overall the operative time in the laparoscopic group (n=27) was longer than the open group (n=27) (235 ± 11 min vs. 195 ± 12 min, P=0. 02). There were no significant differences between the groups in time to regular diet (5. 0 ± 0. 4 d vs. 5. 3 ± 0. 5 d, P=0. 73), time to first bowel movement (5. 3 ± 0. 4 d vs. 5. 2 ± 0. 4 d, P=0. 92), length of hospital stay (5. 9 ± 0. 5 d vs. 7. 1 ± 0. 5 d, P=0. 11), or post operative morbidity (7/25 vs. 11/27, P=0. 34). Conclusion: Laparoscopic reversal of Hartmann operation for diverticulitis is equivalent to open technique in terms of postoperative morbidity. It is associated with longer operative times and does not seem to confer the short term gains afforded to patients who undergo laparoscopy for other colorectal pathology. S109 WITHDRAWN S110 LAPAROSCOPIC TOTAL PROCTOCOLECTOMY FOR ULCERATIVE COLITIS AND FAMILIAL ADENOMATOUS POLYPOSIS. EXPERIENCE IN MEXICO, Federico López Rosales MD, Quintin González Contreras MD, Hector Tapia Cid de León MD, Hómero Rodríguez Zetner MD, Omar Vergara Fernández MD, Department of colorectal surgery. Instituto Nacional de Ciencias Médicas y Nutrición Salvador Zubirán. Mexico City Background: Since the introduction of laparoscopic colectomy in 1991, experience in laparoscopic bowel surgery has gradually increased. Several reports have demonstrated that laparoscopic colorectal resections are feasible, safe, and with good functional outcome, providing an acceptable alternative to laparotomy for a variety of diseases including ulcerative colitis (UC) and familial adenomatous polyposis (FAP). Proctocolectomy with IPAA is one of the most extensive colorectal procedures and performing such an operation in a laparoscopic fashion is even more demanding. The aim of this study is to report our initial experience with this procedure at the Instituto Nacional de Ciencias Medicas y Nutrición Salvador Zubirán (INCMNSZ) in Mexico City. Methods: All the patients in the authors’ institution who underwent a one- or two-stage laparoscopic total proctocolectomy with IPAA between June 2005 and December 2007 were included in the study. All the operations were performed by the same surgeon, who had already completed the learning curve for colorectal laparoscopic procedures. Results: Fifteen patients underwent a laparoscopic proctocolectomy with IPAA by a single surgeon. Thirteen patients 62 ISUCRS XXII BIENNIAL CONGRESS underwent a one-stage procedure, whereas two patients with severe colitis underwent a two-step procedure (urgent subtotal colectomy followed by an elective proctectomy with IPAA). All the cases were managed with a diverting loop ileostomy. Eleven patients underwent a standard double-stapled IPAA anastomosis, two patients with FAP underwent a mucosectomy with a manual IPAA anastomosis, and two patients with UC underwent a handsewn IPAA anastomosis due to failure in the stapling devices. The mean operative time was 172 min, and the mean blood loss was 65 ml. There were two postoperative complications. One patient presented with an early small bowel obstruction due to an internal hernia, which required reoperation. The other complication was a wound infection. The mean return to oral intake was 1. 5 days, and the mean length of hospital stay was 3. 4 days. Conclusion: Even though this was not a comparative study and its limitations due to sample size, with this preliminary data, we conclude that the laparoscopic approach to UC and FAP at our institution is safe, feasible, and effective. However, to achieve the benefits in postoperative outcome, this procedure should be performed only by experienced laparoscopic surgeons. S111 INDUCTION OF LAPAROSCOPY ASSISTED COLORECTAL SURGERY IN A JAPANESE GENERAL HOSPITAL. , Toru Tonooka PhD, Jun Yasutomi PhD, Shinichiro Irabu MD, Daigo Nobumoto MD, Takahiro Nishida MD, Yuko Tashima MD, Masanari Matsumoto PhD, Takahiro Kasagawa PhD, Kimihiko Kusashio PhD, Ikuo Udagawa PhD, Masaru Suzuki PhD, Tatsushi Fukao PhD, Masaru Miyazaki PhD, Department of Surgery, Chiba Rosai Hospital Introduction: Although laparoscopy assisted surgery is a low invasive treatment for benign and malignant colorectal diseases, induction of this technique requires education and experience. Furthermore, the quality of oncological curability must not be lower than traditional open surgery. The aim of this study is to demonstrate the short term results of laparoscopy assisted colorectal surgery (LAC) in our hospital. Methods: The 126 consecutive series of LAC between January 2003 and August 2007 performed at our institution were examined. Age, gender, diagnosis of the colonic disease, colonic site of the disease, surgical procedure were reviewed. Operative time, laparoscopy time, blood loss, history of previous abdominal surgery, conversions, pathological stage (pStage) and lymph nodes (LN) harvested in malignant cases, length of stay, morbidity and mortality were also assessed. Results: No obvious tendencies were seen in age and gender. There were 105 colorectal cancer patients (83. 3%) among all. Major sites of the colonic diseases were sigmoid colon (27. 0%) and rectum (29. 4%). The percentage of LAC patients increased and more advanced pStage cases were indicated as time progression. The mean number of LN was 14, similar to ordinary open colectomies. Operative time and blood loss showed no tendency, while laparoscopy time was increasing as more advanced and complex laparoscopic procedures were adopted. The frequency of patients who had previous abdominal surgery was 27. 8%, while conversions were necessary only for 9. 5%. Major complications were surgical site infection (4. 8%) and ileus (3. 2%). Anastomotic leaks occurred in 2 patients (1. 6%) but no mortality case was present. Conclusions: We started inducing LAC in benign cases or early staged malignancies. As more advanced laparoscopic procedures were adopted, almost the same quality of surgery could be provided without severe complications. S112 THE EFFECTS OF NEOADJUVANT THERAPY ON LAPAROSCOPIC SURGERY FOR RECTAL CANCER, Emre Balik MD, Metin Keskin MD, Burak Ilhan MD, Sumer Yamaner MD, Turker Bulut MD, Buyukuncu Yilmaz, Necmettin Sokucu, Ali Akyuz, Bugra Dursun MD, Istanbul University, Istanbul Faculty of Medicine, General Surgery Department Purpose: The comparison of the surgical outcomes of laparoscopic resections performed for rectal cancer between the two groups of patients either having received neoadjuvant therapy (NAT) or not. Methods: From October 2003 to October ABSTRACT BOOK Podium Papers 2007, 146 patients with rectal cancer were treated by laparoscopy. 56 (38, 3%) patients received NAT preoperatively (NAT group) whereas 90 (61, 7%) patients underwent direct surgery (Non-NAT group). All patients were followed prospectively for survival and complications. Results: Laparoscopic surgery for rectal cancer was performed in 146 patients. Low anterior resection was performed in 116 and Miles operation in 27 patients whereas 3 patients were only laparoscopically explored. The mean operating time was 2, 9 (0, 5 - 5, 0) hours. The operating time was also found to be 2, 9 hours both in the NAT and Non-NAT groups. Conversion to open surgery was required in 13 of 146 patients (9, 3%). Intraoperative additional surgical intervention was required only in three patients all of whom were in the NAT group. TAH+BSO was performed in two of these patients and ureter reconstruction was performed in one single patient. The overall morbidity was 21%, anastomotic leakage occurred in 6 of 146 patients only one single patient of whom was in the NAT group (4, 1%). There was no postoperative mortality. A mean of 18 (4-89) lymph nodes was removed having calculated to be 18 also both in the NAT and the Non-NAT groups. The mean distance of distal margin from tumor was 3 cm in the entire study group. In one patient there was microscopic invasion of the distal margin. Mean hospital stay was 7 (2-45) days both in the NAT and Non-NAT groups as well. Conclusions: Laparoscopic rectal surgery is feasible and oncologically radical. When compared between patients having received neoadjuvant therapy preoperatively and patients directly having undergone surgery without receiving NAT, it can be stated that similar surgical outcomes are encountered revealing no statistically significant differences. Preoperatively administered NAT can be considered to be a safe method as long as indicated. S113 COMPARISON OF CONVENTIONAL AND HANDASSISTED LAPAROSCOPIC SURGERY IN COLON CANCER, HR Yun MD, HK Chun PhD, WY Lee PhD, YB Cho MD, WY Chang MD, RJ Lee MD, YK Cho MD, HC Kim PhD, H Yoo MD, SH Yun MD, JH Park, WY Chang MD, Department of Surgery, Samsung Medical Center, Sungkyunkwan University School of Medicine, Seoul, Korea, Department of Surgery, Cheju University, Cheju, Korea Background: Hand-assisted laparoscopic surgery (HALS) has been introduced as an alternative to the conventional laparoscopic surgery (CLS). This study evaluates the efficacy and short-term clinical outcome of hand-assisted laparoscopic surgery as compare with conventional laparoscopic surgery for colon cancer. Methods: Between May 2000 and December 2006, 351 patients underwent elective colon cancer operation (153 HALS and 198 CLS). The collected data included intraoperative, oncologic, early clinical outcomes and short term oncologic results. Results: The tumor margins were clear in all the patients. The operation time of HALS group resulted in a significantly shorter than CLS group (151. 2¡¾40. 3min vs. 164. 6¡¾34. 9 min; p= 0. 001). On a subgroup analysis according to the site of tumor, in right colon cancer, there was no statistical significance in operation time between groups (158. 8¡¾ 27. 3min vs. 151. 0¡¾28. 0 min; p=0. 251). For the left colon cancer, HALS group had shorter operation time and smaller tumor size than CLS group (149. 4¡¾ 42. 7min vs. 167. 6¡¾35. 7 min; p<0. 001 and 3. 5¡¾1. 8cm vs. 2. 9¡¾1. 8cm; p=0. 007, respectively). There were no statistical differences in intra-operative, oncologic, early clinical outcomes and short term oncologic results except operation time. For the stage III colon cancer, there was no difference in overall survival and disease free survival (p=0. 320 and p=0. 472, respectively). Conclusion: The findings suggest that HALS had shorter operative time, especially in left sided colon cancer but the oncologic and clinical outcome in HALS was similar with CLS. HALS was thought be an effective alternative operative technique in colon cancer. COLORECTAL CANCER AND LAPAROSCOPIC SURGERY II S114 RISK FACTORS AND MANAGEMENT OF ANASTOMOTIC LEAK FOLLOWING RESTORATIVE RESECTION FOR RECTAL CANCER IN THE ERA OF NEOADJUVANT THERAPY, Alexis L Grucela MD, David B Chessin MD, Nicole DeRosa MD, Alex J Ky MD, Sanghyun A Kim www.isucrs.org/ MD, Tomas Heimann MD, Randolph M Steinhagen MD, Mount Sinai School of Medicine Introduction: Surgical resection remains the only curative treatment for rectal cancer. Although some patients require permanent fecal diversion, recent trends have increased the number of restorative resections. Anastomotic leak is a substantial concern following these procedures. We evaluated patients with rectal cancer undergoing restorative resection to identify risk factors and management of anastomotic leak. Methods: We identified 96 consecutive patients who had a low anterior resection for rectal adenocarcinoma. We defined anastomotic leak as clinical or radiographic evidence of leak. We compared demographic, pathologic, and clinical factors to determine risks for anastomotic leak. Results: There were no perioperative deaths. Eight patients (8. 3%) had an anastomotic leak. Risk factors for leak are compared in the Table. Risk Factor No Leak (n=88) Leak (n=8) p-Value Male Gender 45 (51. 1%) 5 (62. 5%) 0. 7 Age >60 46 (52. 3%) 1 (12. 5%) 0. 06 Diabetes 5 (5. 7%) 1 (12. 5%) 0. 4 Preop Radiation 14 (15. 9%) 1 (12. 5%) 0. 1 DAV < 5 cm 29 (33. 0%) 3 (37. 5%) 0. 1 In those patients with a leak, one (12. 5%) required percutaneous drainage, while four (50%) required reoperation with fecal diversion. Of the diverted patients, all had reversal of their stoma (mean of 7. 25 months from initial operation). Conclusion: 8. 3% of patients undergoing restorative resection for rectal cancer may leak. Notably, distance from the anal verge and use of preoperative radiation were not significant risk factors for leak. Routine fecal diversion in patients treated with preoperative chemoradiation is not warranted, even for distal anastomoses. S115 HISTOCLINICAL CHARACTERISTICS OF COLORECTAL CARCINOMA WITH LYMPHOVASCULAR INVASION, Romarico M Azores Jr. MD, Alma N Aquilizan MD, Cynthia A Mapua MS, Francisco V Narciso MD, St. Luke’s Medical Center, Quezon City, Philippines Purpose: Lymphovascular invasion (LVI) in colorectal cancer is significantly associated with nodal metastasis. We studied our data from the Colorectal Cancer Data Bank of the Bioinformatics Department, Research and Biotechnology Division of St. Luke’s Medical Center and determined the histoclinical characteristics of colorectal cancer with LVI. Methods: We studied data bank record from October 2006 to April 2007 of 490 patients with colorectal cancer. There were 212 evaluable cases, 118 cases of which had LVI and 94 cases had no LVI. The following cancer-related factors were assessed: age and gender, stage of the disease, tumor differentiation, site of lesion, and TNM stage. Results: Age and gender seemed to be not associated with LVI (p<0. 05). 64% of those without LVI were in the early stage of the disease while 73% of those with LVI were in the late stage of the disease. The observed difference was significant (p<0. 01). 15. 4% of those with LVI had poorly differentiated tumor as opposed to 2. 2% of those without LVI. The difference was significant (p=0. 004). The site of the lesion seemed to be not related to LVI. 92. 1% of those with LVI had T3 and T4 tumors against 73. 8% of those without LVI and the difference was significant (p=0. 004). Only 30. 6% of those with LVI and 64. 8% of those without LVI had negative nodal metastasis. It was very significant (p<0. 001). 24. 6% of those with LVI and only 10. 2% of those without LVI had distant metastasis. The difference was significant (p=0. 009). By multivariate regression analysis, the following were the predictors of LVI: male patient, poor histologic grade, depth of invasion and nodal status. Conclusion: LVI puts the disease into high risk cancer. S116 FEMALE FERTILITY AND COLORECTAL CANCER, Constantine P Spanos MD, Apostolos M Mamopoulos MD, Apostolos Tsapas MD, 1st Department of Surgery, Aristotelian University, Thessaloniki, Greece Purpose: It is estimated that the incidence of cancer in women aged under 40 is 8%. Females under the age of 40 are in their childbearing years. In the Western World, colorectal cancer (CRC) is the most common malignancy of the gastrointestinal tract. It is the third most commonly diagnosed cancer and the 63 ABSTRACT BOOK Podium Papers 2nd leading cause of cancer-related death in the United States. The incidence of CRC in patients under 40 is 3-6%. Over the past decades, there has been a significant improvement in survival rates due to progress in cancer treatment, including CRC. This has been achieved with advances in adjuvant chemotherapeutic regimens. In the case of locally advanced rectal cancer, radiation therapy is also used. Treatment for CRC may have adverse effects on female fertility. The purpose of this paper is to discuss effects of treatment of CRC on female fertility, as well as options for fertility preservation. Methods: A review of the relevant English language articles was performed on the basis of a MEDLINE search of the keywords: female, fertility, fecundity, colon, rectal cancer, fertility preservation, chemotherapy and radiation. Results: Surgical resection for colon cancer possibly has no effect on female fertility. Resection below the peritoneal reflection may adversely affect fertility, based on lower fertility and fecundity rates associated with pelvic surgery for ulcerative colitis (UC) and familial adenomatous polyposis (FAP). Standard 5FU-based chemotherapy may not have significant effects. The advent of oxaliplatin in adjuvant chemotherapy may be more harmful. Adjuvant and neoadjuvant radiation therapy may cause premature ovarian failure using current dosing schedules. The effect of pregnancy and female hormones on the incidence, progression and recurrence of CRC remains unclear. Established methods for fertility preservation include ovarian transposition and embryo cryopreservation. Oocyte cryopreservation has yielded inferior results. An investigational fertility preservation method is ovarian tissue cryopreservation, with promising results. Ovarian suppression and the use of apoptotic inhibitors are also investigational at present. Conclusion: Young female patients need to be informed about the effects of treatment on fertility and options for fertility preservation. A multidisciplinary approach for appropriate consultation of these patients is mandatory. S117 EFFICACY OF LAPAROCSOPIC COLORECTAL RESECTION FOR HIGH RISK PATIENTS, Jo Tashiro MD, Shigeki Yamaguchi MD, Masatoshi Ishii, MD, Takahiro Sato MD, Shutaro Ozawa MD, Yoshihide Otani MD, Isamu Koyama MD, Saitama Medical University International Medical Center Department of Gastroenterological Surgery Purpose: Minimal invasiveness of laparoscopic resection has a possibility of decreasing postoperative complications for high risk patients. This study was assessed short term results of laparoscopic colorectal resection for high risk patients. Patients: Seventy patients of colorectal cancer resection were enrolled in this study since April 2007 of opening hospital to January 2008. Mean age was 66. 4 year-old. 50 patients were colon cancer and 20 patients were rectal cancer. There was no conversion in those. According to ASA classification, grade 2 or more of grisk grouph was 41 patients, 3 or 4 of ghigh risk group h was 9 patients, and gno risk grouph was 29 patients. Factors of gender, age, lymphadenectomy, operating time, blood loss count, postoperative complication, postoperative hospital stay were assessed between three groups. Results: Mean age was 70. 1 in risk group, 76. 1 in high risk group and 60. 6 in no risk group. No risk group was younger than others. There were no difference of mean operating time and blood loss count, however more lymphadenectomy was performed in no risk group. Postoperative complications occurred in five patients. Those were 2 anastomotic leak , 2 anastomotic bleeding, and 1 intestinal obstruction. There was no difference of complication frequency in each group. Median postoperative hospital stay was 7 days in all groups and no difference. Conclusion: Even though patient was high risk, laparoscopic resection was performed safely without increasing complication and postoperative hospital stay. S118 TWO DIFFERENT LAPAROSKOPIC TECHNIQUE ON RECTAL PROLAPSUS, Turker Bilgin MD, General Surgeon, Etimesgut Military Hospital, Dept. of Surgery. Ankara, Turkey Purpose: The laparoscopic approach promises to become the gold standart for the transabdominal management of full thickness rectal prolapsus. The aim of this study was to review our experience and to highlight the functional results achieved with this two technique. Method: Data were prospectively collected and analyzed on 48 patients who underwent laparoscopic rectopexy without resection for full-thickness rectal prolapsus 64 ISUCRS XXII BIENNIAL CONGRESS between 2001-2008. These were two major group each group had 24 patients. One patient had undergone to open surgery from laparoscopy. Mean age was 48 (range, 20-74) years. The preoperative and postoperative course of each patient was followed up , with attention paid to first bowel movement , hospital stay, duration of surgery fecal incontinence , constipation, recurrent prolapsus, morbidity and mortality . Follow-up was made by clinic appointments and, if necessary by telephone review. Results: 48 patients were available for follow-up. The follow-up time was 9 years. In both groups the results are really similar but the main difference was on the long therm results. Eighty percent of patients reported alleviation of their symptoms after the operation. Sixty-nine percent of the constipated patients experienced an improvement in bowel frequency. Four (2. 5%) patients had full-thickness rectal prolapsus recurrence. Mucosal prolapsus recurred in 2(1. 8%) patients. Mean duration of surgery was 75 (range, 50-150) minutes. Postoperatively, the median time for first bowel movement was nearly twenyfour hour. Median hospital stay was four (range, 2-6) days. Postoperative morbidity included a port site hernie (1 case), and a superficial wound infection (one case). Conclusion: Laparoscopic suture rectopexy without resection is both safe and effective in this frequently frail population and offers a minimally invasive approach that may have potential advantages for selected groups of patients with full-thickness rectal prolapsus but long therm following series the classic abroach like posterior rectopecsi was much effective then the suture rectopexy. Laparoscopic techniques must to be the same plan with classic accepted surgical procedures. S119 USE FULNESS OF FALS IN LAPAROSCOPY ASSISTED COLORECTAL SURGERY, Jun Yasutomi MD, Toru Tonooka MD, Ikuo Udagawa MD, Kimihiko Kusashio MD, Masanari Matsumoto MD, Masaru Suzuki MD, Katashi Fukao MD, Department of Surgery, Chiba Rosai Hospital FALS : finger assisted laparoscopic surgery is a novel technique in the laparoscopy assisted colorectal surgery. Especially in laparoscopic low anterior resection for rectal carcinomas, we often find difficulty in making a fine view of the surgical field during pelvic dissection, gut clamping for rectal washout, intracorporeal anastomosis and so on. Between January 2003 and February 2008, we performed 147 laparoscopy assisted colorectal surgeries including 37 sigmoid colon resections, 45 anterior resections, 1 abdomino-perineal resection and 3 total procto-colectomies. Initially, we immediately converted laparoscopic into open surgery once we found difficulty in laparoscopic procedures. Since we adapted this new technique, we have been able to perform the advanced and complex laparoscopic procedures. FALS is an easy and helpful method using the abdominal wall sealing device : ALEXIS WOUND RETRACTOR ( Applied Medical, Rancho Santa Margarita, CA) and surgical gloves, that makes it possible to apply almost all kinds of instruments for open surgery. Using this simple technique, we can easily set up additional trocars, and also insertion of the instruments such as uterine retractor, intestinal forceps or intestinal clamps and variety of devices for open surgery has become possible. Especially, the Doyen intestinal forceps with curved blades is useful, which we can insert into intraperitoneal cavity without cutting off the finger parts of the surgical glove. Furthermore, we can switch from laparoscopic to open surgery and also open to laparoscopic surgery under re-pneumoperitoneum. We would like to present some useful techniques in laparoscopy assisted anterior resections, such as in TME ( total mesorectal excision ), in intra-rectal lavage (rectal washout), in DST (double stapling technique) anastomosis and in intra-pelvic lavage including the test for anastomotic leakage etc. S120 MINIMAL INVASIVE SURGERY FOR RECTAL CANCER. SHORT TERM RESULTS OF SINGLE CENTER, Emre Balik MD, Metin Keskin MD, Burak Ilhan, Sumer Yamaner MD, Turker Bulut MD, Yilmaz Buyukuncu, Necmettin Sokucu MD, Ali Akyuz, Dursun Bugra MD, Istanbul University, Istanbul Faculty of Medicine, General Surgery Department Aim: Laparoscopic treatment of rectal cancer has gained favor in the recent years but there is no consensus about rectal cancer disease on this technique as colon cancer . The aim of this study is to assess the reliability of laparoscopic anterior resection (LAR) abdominoperineal resection (APR) and the analysis short-term ABSTRACT BOOK Podium Papers outcomes o the rectal cancer. Methods: The charts of 146 rectal cancer disease patients data’s were collected retrospectively after resection for rectal adenocarcinoma performed by minimal invasive access between October 2003 and 2007 . Patients undergoing emergency surgery were excluded. Demographic, conversion rates, functional, oncologic and early surgical outcomes were analyzed. Results: LAR and APR was performed in 143 patients, and conversion to laparotomy was required in 13 (8. 9%) cases. Fifty two patients’ tumors were located at proximal rectum, 29 were in the middle and the rest of them located at distal rectum. Fifty six underwent long course neoadjuvant therapy before the surgery. Avarege operation time for nonconverted patients was 185 minutes (overall 238 minutes). Total mesorectal excision (TME) was performed in tumors of the mid and low rectum in 96 patients. Only 50 patients needed temporary stoma. The mean length of hospital stay (LOS) was found 7 days. There was no mortality in the first 30 days. Overall morbidity rate was 21%. Morbidity of anterior resection included 6 anastomotic leaks after laparoscopic surgery. The mean distal surgical distance was 3 cm. The mean incision length was 5. 5 cm and the mean number of nodes collected was 18. Conclusions: The outcomes of this study suggest laparoscopic surgery for rectal cancer is a reliable procedure. Oncologic requirements were respected; parameters such as length of distal margin, number of node, functional outcomes retrieved were acceptable. Data’s and multicenter trials are needed for long term results. www.isucrs.org/ S121 LAPAROSCOPIC ASSISTED INTERSPHINCTERIC RESECTION FOR VERY LOW RECTAL CANCER, Yoshiya Fujimoto MD, Hiroya Kuroyanagi MD, Masatoshi Oya MD, Masashi Ueno MD, Takashi Akiyoshi MD, Toshiharu Yamaguchi MD, Tetsuichiro Muto MD, Department of Gastroenterological Surgery, Cancer Institute Hospital, Tokyo, Japan Introduction: Laparoscopy-assisted surgery for rectal cancer has been shown to be both technically feasible and a safe alternative to laparotomy. In addition, intersphincteric resection (ISR) has recently been reported as a promising method for sphincterpreserving operation in selected patients with very low rectal cancer to avoid a permanent stoma. Methods: From July 2005 to December 2007, 22 patients with very low rectal cancer underwent laparoscopy-assisted total mesorectal excision (TME) with ISR followed by hand-sewn coloanal anastomosis and diverting ileostomy. Seven patients received preoperative chemoradiation therapy. Results: The average age of the patients was 58. 8 years (range 33 to 79), and 59. 1% were male. The median tumor size was 27. 5 mm (range 10 to 90) and distance from the dentate line was 1 cm (range 0 to 3). The median operation time was 280 min (range 195 to 374), and blood loss was 70 ml (range 0 to 235). There was no mortality. The complications were occurred in 3 cases, comprised of one with wound infection and two with obstructions, and no anastomotic leakage was observed. They recovered with conservative therapy. The median duration of postoperative hospitalization was 17. 5 days (range 11 to 121). Lymph node metastases were present in 9 cases. Pathological stage I according to UICC classification was confirmed in 10 cases, stage II in 1, stage III in 9, and no cancer (histopathological findings showed complete response) in 2. One patient underwent radiation therapy and chemotherapy due to positive resection margin, but died of recurrent disease. The other developed lung metastasis. Remaining 20 patients were still alive without recurrence. Conclusions: The current study demonstrated laparoscopic TME and ISR is both technically feasible and a safe alternative to laparotomy in the short term with favorable postoperative outcome. 65 ABSTRACT BOOK VIDEO Papers MIXED PLENARY SCIENTIFIC SESSION V001 LAPAROSCOPIC TOTAL ABDOMINAL COLECTOMY WITH RECTAL HARTMANN’S POUCH AND CONSTRUCTION OF END BROOKE ILEOSTOMY, Badma Bashankaev MD, Christina Seo MD, Jared Frattini MD, Paula Denoya MD, Marwan Moussa MD, Steven D Wexner MD, Department of Colorectal Surgery, Cleveland Clinic Florida This video depicts a case of a 15 year old female with mucosal ulcerative colitis (MUC). She was diagnosed 3 years ago and failed conservative treatment. She has already sustained multiple bone fractures. She and her family are quite apprehensive about lifelong commitment to multiple immunosuppressive medications. The patient’s choice was to have a laparoscopic subtotal colectomy with rectal Hartmann’s pouch and end Brook ileostomy. Surgery: Abdominal access was performed with the Hasson technique. Four additional 10 mm ports were placed through horizontal stab wounds lateral to the left epigastric vessels, one in each upper quadrant and one in each lower quadrant. With a combination of head up, head down, left side up and left side down, the entire colon was carefully mobilized along the line of Toldt. The left and right ureters, duodenum, and pancreas were carefully reflected posteriorly out of harms way. The entire small bowel appeared normal without any evidence of Crohn’s disease. The entire colon appeared diseased consistent with mucosal ulcerative colitis. The division was undertaken from the terminal ileum, around to the rectosigmoid junction carefully protecting and preserving the ileocolic, superior rectal, and inferior mesenteric vessels. The rectosigmoid junction was divided stapler. The previously identified right ileac fossa ileostomy site was re-identified, and a 2 cm disk of skin was excised. An additional 10 mm port was placed, and the staple line at the distal sigmoid was gently grasped and the entire specimen withdrawn through the stoma site. After verification of appropriate orientation of the small bowel and its mesentery, irrigation and verification of meticulous hemostasis, all port sites were closed with 3-0 Vicryl with the Neat-stitch device under direct vision. The stoma was then primarily matured. Patient tolerated surgery well and discharged on a postoperative day 3. V002 EMERGENCY LAPAROSCOPIC RIGHT HEMICOLECTOMY IN ILEO-COLIC INTUSSUSCEPTION PATIENT DUE TO CECAL CANCER, Koo Yong Hahn MD, Jeoung Hwan Keum MD, Yong Geul Joh PhD, Seon Hahn Kim PhD, Deprtment of Surgery, Seongnam Central Hospital Objectives: Intussusception of large bowel in adult is rare and associated with malignancy in 70% of patients. To avoid 66 ISUCRS XXII BIENNIAL CONGRESS tumor emboli spread during surgery, an attempt of reduction of intussusception should be excluded. For that reason, surgical complete resection is appropriate for treatment. Owing to huge mass, adhesions of surrounding structures such as ileo-colic vessels, ureter and duodenum, it is very hard to handle by laparoscopically. Method: A 39-year-old female patient visited emergency department due to right lower quadrant pain and abdominal distension. A computerized tomography(CT) revealed right lower quadrant mass, bowel inflammation and edema. Under the impression of ileo-colic type intussusception, we did laparoscopic right hemicolectomy. Result: The operation time was 250minutes and blood loss was 100cc. The first gas passage was postoperative 2nd day and stool passage was 3rd day. The first sips of water was postoperative 3rd day. The pathologic report demonstrated that the tumor was mucinous carcinoma and extended to subserosa. The 3 lymph nodes metastasis was found (3/25). Patient was discharged postoperative 11th day without complication. Conclusion: We conducted laparoscopic right hemi-colectomy in ileo-cecal intussusception patient successfully. The application of laparoscopic surgery in intussusception depands on laparoscopic expertise of surgeon, extent of disease, patient condition. V003 PERINEAL RECTOSIGMOIDECTOMY AND VAGINAL HYSTERCTOMY IN A PATIENT WITH RECTAL PROCIDENTIA AND VAGINAL PROLAPSE, Eduardo Brambilla MS, Paulo Roberto Dal Ponte MD, Marcos Antonio Dal Ponte MD, Viviane Raquel Buffon MD, University of Caxias do Sul Introduction: Rectal procidentia is relatively rare and more common in older and female patients. In this group, other pelvic floor disturbs can also be associated. Once the ethiology as well as its treatment are doubtful, many are the surgical alternatives. Perineal procedures are considered attractive due to the low morbidity rate specially in this group. Case Report: A 74-yearold patient, hypertense, with a brain damage caused by a brain stroke has manifested over the past 6 months reducible rectal procidentia, which is exteriorized by walking. The patient reported chronic constipation with some episodes of faecal incontinence. By examining the patient, rectal procidentia and third-grade uterine prolapse was presented. Perineal rectosigmoidectomy associated with vaginal hysterctomy was the therapy performed. There were not any complications during the trans and postoperative period. After 60 days accompanying the patient, this one did not present any reincidence of prolapse or constipation. The faecal incontinence became less frequent. ABSTRACT BOOK Poster Papers Anorectal Diseases P001 A MODIFICATION IN LONGO’S TECHNIQUE SIGNIFICANTLY IMPROVES THE RESULTS OF STAPLER ANOPEXY IN HIGHER GRADE HEMORRHOIDS, Pankaj Garg MS, Fortis Super Speciality Hospital, Mohali, India Purpose: High recurrence rates in patients with higher grade hemorrhoids are being reported with Stapler anopexy. The prime reason for this is the limiting capacity of stapler PPH03 to excise the adequate amount of mucosa which leads to residual prolapse and recurrence. So in these cases, stapler anopexy converts higher grade of hemorrhoids into a lower grade which subsequently require banding or injection sclerotherapy for treatment. In our study, we assessed the patient on the operating table immediately after completing the stapler anopexy. If the residual prolapsing hemorrhoids were found, they were ligated with 2-0 vicyl and cut. So a procedure required later on for treating recurrence was done with primary procedure only. Methods: A total of 42 patients were recruited over 2 years. 19 patients with grade 3&4 (Standard group) and 12 patients with grade 2 hemorrhoids (Gr 2 group) were operated by standard Longo’s technique to serve as controls and compared with 11 patients with grade 3&4 hemorrhoids operated by modified technique in which the residual prolapsing hemorrhoids were ligated and cut (Ligated group). The three groups were matched for age and sex. The patients were assessed on satisfaction scale and checked for recurrence at 3, 6 and 12 months. Results: The mean age was 46. 1, 51.3 and 48.7 years and the mean follow up was for 412, 464 and 405 days in three groups, Grade 2, Standard and Ligated groups respectively. The hospital stay (mean-1.42, 1.21 and 1.3 days), painful days in post-operative period (mean-10.3, 7.05 and 8.68 days) and days required to resume normal work (mean- 17.0, 8.4 and 12.7 days) were not significantly different in the three groups, Grade 2, Standard and Ligated groups respectively. [p>0.05, ANOVA]. Recurrence rates were significantly lower in Ligated group (1/11, 9.1 %) compared to Standard group (12/19, 63.2 %) [p<0.0067, ANOVA]. Percentage of patients highly satisfied by the procedure was significantly higher in Ligated group (10/11, 90.1 %) compared to Standard group patients(6/19, 31.2%) [p<0.0024, ANOVA]. Incontinence (urge, gas or liquid) and anal stenosis was similar in all three groups. Conclusions: In higher grade of hemorrhoids, compared to doing stapler anopexy alone, performing ligation and cutting of the residual hemorrhoids on the operating table after doing stapler anopexy significantly reduced recurrence rates and improved satisfaction rates. Larger long term studies are needed to substantiate this. P002 CONDYLOMA ACUMINATUM IN THE RECTUM, Sonny S Wang MD, Sefik Gokaslan MD, Yomi Fayiga MD, Saul Sokol MD, University of Texas Southwestern Medical Center, Dallas, Texas, USA Introduction: Anal condylomas are usually found in the distal anal mucosal tissue, anoderm, or proximal perianal margin. Human papillomavirus (HPV) is the cause of condyloma acuminata and is often associated with HIV infection. We present a rare case of condyloma acuminatum located in the rectum. Method/Case Report: A 43 year-old Caucasian male presented to our gastroenterology service with a chief complaint of bright red blood per rectum for several weeks. His past medical history is significant for HIV and hepatitis B diagnosed 20 years ago. There was prior history of anal receptive intercourse. Our patient was on highly active antiretroviral therapy (HAART) for HIV with a CD4 count of 138 cells/ mL at the time of his evaluation. An ensuing colonoscopy revealed a 2 cm anterior midline mass at 5 centimeters away from the anal verge. Biopsy revealed rectal condyloma acuminatum with moderate (high grade) squamous dysplasia. Patient was subsequently referred to us for further management. The diagnosis of rectal condyloma was a surprise because of its location. Further digital and proctoscopic examination confirmed the previous endoscopic findings. The mass, however, had fungating and friable features suggestive of neoplasm. We repeated the rectal biopsy due to the unusual condyloma location in the initial diagnosis but also to exclude neoplasm. We also undertook complete fulguration of the visible mass at the time of repeat biopsy. Final pathology was again high grade squamous dysplasia arising from condyloma acuminatum www.isucrs.org/ in the rectum. On postoperative follow up, our patient recovered uneventfully. We plan to follow this patient closely and to rebiospy the area if the mass returns or neoplastic features arise. Conclusion: Condyloma acuminatum in the rectum is an uncommon diagnosis. To our knowledge, only one other condyloma acuminatum located in the rectum has been reported. Patel et al reported a 66 year-old Caucasian heterosexual nonHIV male diagnosed with rectal condyloma. 1 Clinicians need to be aware that such a diagnosis exists. The management of condyloma acuminatum in the rectum is similar to anal condyloma that includes local excision and destruction usually by fulguration. Reference: 1. Patel PH et al.

P003 DOPPLER-GUIDED HEMORRHOIDAL ARTERY LIGATION AND RECTOANAL REPAIR(DG-HAL & RAR) AS A TREATMENT OF INTERNAL HEMORRHOIDS, Sung Wook Cho MD, Soon Sup Chung MD, Ryung Ah Lee MD, Kwang Ho Kim MD, Ewha Womans University Medical School Department of Colorectal Surgery Backgrounds: Hemorrhoidectomy is widely used as the procedure for the treatment of internal hemorrhoids. However, the problems with conventional hemorrhoidectomy consist of postoperative pains, and delayed wound healing. For this reason, minimally invasive procedure (ex. Rubber band ligation, sclerotheraphy, laser treatment) or PPH were developed, but, they also have some fatal complications. Purposes: To introduce Doppler-guided hemorrhoidal artery ligation and Rectoanal repair(DG-HAL & RAR) as a new treatment of internal hemorrhoids and report a preliminary experience of this procedure. Methods: From November 2007 to January 2008, 23 patients who don’t have other anal problems (ex. Anal fisula, anal fissure) except internal hemorrhoid grade II-IV were treated by DG-HAL & RAR. Firstly, under the litotomy position, the proctoscope with an incorporated Doppler probe was inserted and identified location of hermorrhoidal artery. Once located, the artery was ligated with a ‘figure of eight’ absorbable suture into submucosa. And then prolapsed hemorrhoidal pile was lifted at rectal mucosa by continuously suturing to 5mm above dentate line and tying. The procedure was repeated at the 1, 3, 5, 7, 9, and 11 o’clock position. We analysed hospital day, postoperative pain, time of returning to work, and recurrence. Results: The patient’ mean age is 48.3¡¾14 and they consist of 23 (Grade II: 8, Grade III: 11, Grade IV: 4). Ten patients were male and 13 female. The mean operation time was 35 minutes and postoperative hospital stay was 1.4 days. The mean time of returning to work was 1.8 days. There was no severe pain requiring injection of analgesics. Some patients had only tenesmus and minor bleeding. After one month, 2 patients still had prolaping symptoms. Conclusions: Dopplerguided hemorrhoidal artery ligationand Rectoanal repair(DGHAL & RAR) is safe and less painful procedure comparing with conventional hemorrhoidectomy. DG-HAL & RAR is an effective alternative for the treatment of internal hemorrhoids. P004 TRANSPOSITION OF GRACILIS MUSCLE IN THE TREATMENT OF RECTOVAGINAL FISTULA RECURRENT.

The patient evolution good after closure colostomy after comprobation closure of fistula. Key words: rectovaginal fistula, muscle gracilis. 67 ABSTRACT BOOK Poster Papers P005 WHITEHEAD’S HEMORRHOIDECTOMY: DO WE HAVE TO ABANDON THIS PROCEDURE?, Ok Joo Paek MD, Seung Yeop Oh MD, Kwang Wook Suh MD, Department of Surgery, Ajou University School of Medicine, Suwon, Korea Introduction: Whitehead’s operation provides the only chance of removing all hemorrhoids, giving the least possibility to relapse and is highly cost effective. Analyzing personal data, we were to answer the question: whether the Whitehead operation should be abandoned or not. Patients and Methods: From March 1991 to January 2007, 210 patients with grade 4 hemorrhoids underwent Whitehead’s hemorrhoidectomy by the author. The ¡®grade 4¡¯ means the complex of internal and external hemorrhoids occupying entire perimeter of anal verge, which are always prolapsed. All patients were complaining additional symptoms such as tenesmus, narrow or deformed stool, or the sense of blockade during the defecation. The outcome of the operation was retrospectively assessed by reviewing medical records with regard to total blood loss during the procedure, operation time, hospital stay, and types of complications. On the second visit (4 weeks postoperatively), degree of the anal stricture was measured with Hegar dilator. On April 2007, 196 of all patients (93.3%) were contacted. The patients were asked if there were any long-term complications and to choose a point of satisfaction from 0(the worst) to 10(the best). Results: Average operating time was 20.9 minutes and blood loss was 51cc. No patient required transfusion. Urinary dysfunction (83.3%) and mild fecal incontinence (85.7%) were noted. In average, the fecal incontinence disappeared by the second week in all patients. All patients pointed out the ¡®pain¡¯ was the most notable complication and in fact the parenteral opioids were required for all patients. When asked if the stool caliber was small, all patients replied positively. Ten patients complained some defecation difficulty but patients who had passed more than 12 months after the operation did not complain defecation difficulty whatsoever. For the objective assessment of anal stricture, Examining by Hegar dilators, mean diameter was 7.8 +/- 5.5 mm. Mean satisfaction score was 7.0 +/- 2.3. Two patients (0.95%) complained recurrent hemorrhoid. Four patients complained difficulties in the defecation revealed pinpoint narrowing. They were admitted again and were successfully treated by stricturotomy. One patient underwent anoplasty. Conclusion: We think the hemorrhoid is the benign disease and therefore, it should be treated as conservative as possible. However, when it reaches the end stage in which anal dysfunctions are combined, we must decide the optimal type of surgical treatment. Radical, circumferential hemorrhoidectomy should remain as one of the operative choices. P006 COMPLETE CLEARANCE OF INTRA-ANAL CONDYLOMA ACUMINATUM: PODOPHYLLIN APPLY THROUGH ANOSCOPY COMPARED WITH SURGERY, SeokGyu Song MD, Woo-Jung Nam MD, Do-Yeon Hwang MD, JongKyun Lee PhD, Proctology Department, Song-Do Medical Center, Seoul, South Korea Purpose: Condyloma acuminatum which is usually sexual transmitted and caused by Human Papilloma Virus. The incidence of anal condyloma acuminatum has been increasing because homosexual and bisexual behavior are not uncommon. Condyloma acuminatum has been known for high recurrence rate after treatment. Especially condyloma acuminatum affected to intraanal area has been higher recurrence and complication. Despite the perianal condyloma acuminatum has been managed by many different methods, main treatment for intra-anal condyloma acuminatum is still surgery. The aim of this study is to investigate the outcomes after podophyllin apply through anoscopy to intra-anal condyloma acuminatum. Methods: From June 2006 to December 2007, total 105 patients visited our clinic for anal condyloma acuminatum. Among these patients, the focus of the present study was the 62 patients who had intra-anal condyloma acuminatum confirmed by pathology department and who had follow up at least 4 weeks after treatment. Of the 62 patients, 39 patients underwent surgery and 23 patients received podophyllin treatment. The treatment method was selected by patients. The surgical treatment was excision and elctrocoagulation under local or spinal anesthesia. The podophyllin was applied to intraanal lesion through the anoscopy with no anesthetics or mucosal 68 ISUCRS XXII BIENNIAL CONGRESS protective agent. We performed one time per week at outpatient clinic. Comparison between the treatments were analysed by the Chi-squared test. Significance was defined as P<0.05. Results: The complete clearance were 26 for 39 patients in the surgery and 14 for 23 patients in the podophyllin treatment(surgery: 66.7%, podophyllin: 60.8%, P>0.05). There was no significant difference in complete clearance rate between the two groups. Age and sex distribution were similar in the two groups. The mean follow up periods were 9.5 weeks after surgery and 8.7 weeks after podophyllin treatment. In treated wih podophyllin, the mean frequency of treatment were 4.2 times. There was no specific complication after podophyllin application, but four patients underwent surgery had anal fissure which were resolved with conservative treatment. Conclusions: Podophyllin application is safe and effective office based procedure for intra-anal condyloma acuminatum. It has less complication and acceptable recurrence rate compared to surgery. Our results support podophyllin application can be an alternative treatment method for intra-anal condyloma acuminatum. P007 STRAINING DIAGNOSIS FOR HEMORRHOIDAL DISEASES, Naoto Saigusa PhD, Jun-ichi Saigusa PhD, Sumio Saigusa PhD, Saigusa Clinic of Coloproctology Purpose: The examinations for anorectal diseases are customarily performed with the patient lying down on an examinating table. However, usually internal hemorrhoids are classified if they are prolapsed or not during defecation. Therefore, in order to make a correct diagnosis for hemorrhoidal diseases it would be ideal to inspect the buttocks during straining in accordance with gravity while the patient is in a position of squatting or sitting on a toilet seat. We determine the usefulness of this diagnostic method which was introduced 80 years ago in our clinic. Methods: Following four data on our examination flow were prospectively investigated at the patients’ first office visit at Saigusa Clinic during the period from January 2003 to May 2007; 1) voluntarily expressed chief complaints of patients, 2) interviewed subjective degree of hemorrhoids by questioning whether they are aware of their prolapse ani or not, 3) objective degree of hemorrhoids observed under conventional proctoscopy with the patient in a spine lithotomy position, 4) objective degree obtained at an inspection of the buttocks using a hand mirror during the patient straining in toilet (straining diagnosis). This diagnostic procedure was carried out by three senior proctologists who have more than 15 years’ clinical experience. Paired t-test was applied for statistical analysis. Results: We had 1000 patients who presented symptomatic hemorrhoids of more than the first degree during that period. Among them, 570 patients had two or more subjective complaints. Only 592 patients (59%) voluntarily complained prolapse ani. Anal bleeding and pain were presented in 494 (49%) and 202 (20%) patients respectively. The value of subjective degree of hemorrhoids carefully interviewed at office was significantly higher than that of self-stated one with their mean of 2.24 vs. 1.97 (p<0.01). The objective degree diagnosed at straining was significantly higher than that of under anoscopy with their mean of 3.02 vs. 2.97(p<0.01). Conclusions: A considerable number of patients were not aware of their prolapse. The conventional examination only by use of anoscope is not sufficient. Even if the physicians were well clinically trained and experienced, they could not always make a correct diagnosis without using the straining technique. Affirmative questioning to the patients and straining diagnosis are essential for accurate evaluation of hemorrhoidal diseases in order to choose adequate treatment. P008 THE METHOD OF TREATMENT EXTRA- AND TRANSSPHINCTER RECTAL FISTULAS, Tengiz F. Bochoidze MD, Iuri D. Tavdidichvili MD, K. Eristavi National Center of Surgery, Tbilisi., Georgia The goal of the work is improvement of surgical treatment results of extra- and transsphincter fistulas in ano. Methods: The method of closed intrafistular coagulation includes introduction of proper sized silver probe through the external opening up to internal opening of the fistulous tract. The probe is connected with coagulator and under the visual control electro cauterization with definitive regime is carried out. ABSTRACT BOOK Poster Papers After coagulation and excising of the internal opening Latex drainage is placed through the all length of the fistulous tract. The internal opening is closed with suture and plastic operation on rectal mucous wall by Judd - Robles is performed. External opening is excised and kept open. In case of multichannel fistula, separate cauterization of each channel is indicated. Drainage stays for 2 - 4 days, after what washing of the wound by antiseptics and antibiotics is done. Healing of the fistula takes 7 - 10 days. Results: Postoperative period passes without complications. 32 patients underwent surgery be abovementioned method. The patients have no compliance, complication and recurrence after 2 years of operation. Conclusion: The method is less invasive and allows eradicating the fistula in ano without compromising anal sphincter function which is restored just after removing of gas derivation tube and tampons from the rectum. P009 SPECTRUM OF ANORECTAL DISEASES IN AN INDUSTRIAL TOWNSHIP, Sunil Kumar Gupta MS, Main Hospital, Bharat Heavy Electricals Limited, Ranipur, Haridwar, Uttarakhand, India Spectrum of anorectal disorders prevalent in industrial township population where the author is practising as consultant surgeon is analysed for a period of two years. 481 patients afflicted with anorectal problems attended special weekly clinic. 43.8% (n=211) presented with haemorrhoids of varying degrees. 25.1% (n=121) had fissure-in-ano. Fistula-inano constituted 12.6% (n=61). 6.4% (n=31) patients presented with perianal suppuration. Pilo-nidal sinus comprised 4.9% (n=24) in the study group. 4.5% (n=22) patients had pruritis ani. Rectal prolapse was encountered in only 1.45% (n=7) and rectal cancer was seen in only 0.83% (n=4) patients. Anorectal injuries were not included in the study due to non availability of proper information about these patients. Patients were questioned about their bowel and food habits. Spicy food stuff and straining at stools were found to be main causative factors in patients with piles, fissure-in-ano and rectal prolapse while poor hygiene, straining at stools were chiefly responsible for pilo-nidal sinus, perianal suppuration, fistula-in-ano and pruritis ani. Management of all the patients who comprised the above mentioned group depending upon the disease entity and extent of the disease is discussed along with their followup and outcome. Various treatment modalities in patients with haemorrhoids, pilo-nidal sinus and fistula-in-ano are discussed. P010 BANDING? NO. HIGH MACRO BANDING, Jose A Reis Neto PhD, Jose A Reis Junior MD, Odorino Kagohara MD, Joaquim Simões Neto MD, Sergio Bassi MD, CRN (Clinica Reis Neto) Since the last decade the idea of intervening higher in the anal canal to impede the downward displacement of the hemorrhoidal cushions, acting at its origin, has becoming more and more accepted. The strategy of removing a segment of the anal canal to eliminate the zone with degeneration of the collagen and elastic tissue stroma and suspending the lower anal canal has shown to be effective for hemorrhoidal disease grades II and III. Based on the same principle a new technique of ligature was developed based in two aspects: 1. to promote a better fibrosis and fixation by banding a bigger volume of tissue;2. to perform this fixation at the origin of the hemorrhoidal cushion displacement, preventing the cushion to slip through the anal canal. Technique: No especial preparation is necessary. If properly performed the High Macro banding is painless. However to facilitate the banding is recommended to inject 1. 5 ml of lidocaine at the submucosa of the anal canal with a fine needle. This injection must be performed, higher in the anal canal, 4 to 5 cm above the pectinate line, according to location of internal piles. If the patient has more than one pile, two or more areas could be injected. This maneuver facilitates the suction of the mucosa. The banding instrument for High Macro ligature consists of a double drum thirty millimeters (3 centimeters) in length and fifteen millimeters (1, 5 centimeters) in diameter. The bands are 2 millimeters in diameter when unexpanded and 1. 5 cm when loaded onto the drum. The suction device is adapted to a suction pump and the pile is drew downward by sucking the mucosa of the anal canal; with this method the surgeon can hold the anoscope with one hand and use the other one to release the bands. It is recommended to utilize a longer and www.isucrs.org/ wider anoscope to obtain a better view of the anal canal which will facilitate to inject the submucosa higher in the anal canal and to insert the rubber band device. The pile must be banded higher in the anal canal (4 to 5 cm above the pectinate line). The mucosa, previously injected, is gently suctioned at the same time that the rubber band device is slowly moved downward, parallel to the anoscope, for just a small distance. It is preferable to treat all the hemorrhoids in one single session (maximum of three). When using the macro rubber-band, it is preferable to band the existent piles at different levels, to avoid stricture of the anal canal. Sequential single banding can be performed, but at least 30 days should elapse between the sessions Results: It was observed the following complications in 825 patients treated: edema in 1, 57%, tenesmus in 0, 6%, pain (need for parenteral analgesia) 1, 57%, small bleeding in 5, 45%, profuse bleeding in 0, 6% and urinary retention in 0, 12% of the patients. None of the patients needed hospitalization for the observed complications. Recurrence of the symptoms occurred in 3, 87% of the patients, all of them treated by a new banding. P011 AMBULATORY ANAL SURGERY FOR BENIGN DISEASE: SEDATION WITH LOCAL ANESTHESIA, Jose Q Reis Neto PhD, Jose Q Reis Jr, Odorino Kagohara, Joaquim Simoes Neto, Sergio Banci, CRN Introduction: The aim of this paper is to evaluate the results obtained with this technique in xxx patients operated on from 2002 to 2007. Technique: Sims (left lateral) position with the pelvis raised on a sandbag is the best position for the procedure. The lithotomy position should be avoided. . Sedation is achieved with Midazolan (2 to 5 mg), Petidine Cl. (50 to 100 mg) and Propofol (10 to 20 mg). Local anesthesia is performed Ropivacaíne Cl. 0, 75% (20 to 40 ml, according to patient weight). Nalozone Cl. (0, 1 to 0, 4 mg. is used to revert the effect of Petidine Cl., at the end of the procedure. Meloxicam (or similar) is used at the end of the surgery to prevent immediate post-operative pain. Results: evaluation of 1805 patients operated on this scheme showed that all of them had a post-operative without immediate complications and needed hospitalization. Of these patients, 79% were operated on from heorrhoidal disease, 8.4% of chronic anal fissure, 5.4% of anal fistula (fistutomy) and the others from various benign anal disease. Complication: It was observed: late post-operative hemorrhage in two patients (0, 11%) operated on of hemorrhoids, urinary retention in three patients (0.16%) patient and wound infection in four patents (0, 22%). However, none of those patients required hospitalization. Conclusion: the procedure of sedation with local infiltration proved to be an excellent method for treatment of benign anal diseases. Ambulatory surgical procedure, independently of the etiology, but of the surgical care and surgeon expertise, with adequate selection of patients, is nowadays one better cost/benefit approach for most of the benign anal diseases. Benign Colorectal Diseases P012 ZIONE (ALTA) INJECTION THERAPY FOR HEMORRHOID & PROLAPSE: DIRECTLY ADMINISTERED INTO HEMORRHOIDS BY METHODS OF FOUR-STEP INJECTION TECHNIQUE, Mitsuyo Kosugi MD, Toshihiro Ono, Chief of Proctology Center, Saitoh Clinic, Toyama,Japan Four-step Injection Technique: ALTA Injection is directly administered into hemorrhoids by the 4-step method injection, and this procedure is important for the efficacy and safety of ALTA Injection therapy. Methods of 4-step Injection: ALTA Injection is directly administered into hemorrhoids by the 4-step method injection. Since this procedure is important for the efficacy and safety of ALTA Injection therapy, and you need a sufficient experience and practice of proctology. The 1st step is injection into the submucosal layer of the upper polar region of a hemorrhoid, giving usually a total of 3ml. The 2nd step is injection into the submucosal layer of the central region, giving the standard dose volume is 1ml higher than hemorrhoid volume, usually a total of 2-4ml. The 3rd step is injection into the lamina propria mucosae of the central region, giving about half volume of the 2nd step, while slowly pulling back the needle tip following the 2nd step. The 4th step is injection into the submucosal layer of the lower pole. The needle tip is inserted 69 ABSTRACT BOOK Poster Papers at the region 0. 1-0. 2 cm above the dentate line, giving 1-3ml. After the completion of the injection into all major hemorrhoids, all injected regions are massaged well for a few minutes to fully diffuse the drug solution. Proct-speculum for 4-step Injection: We use the cylindrical proct-speculum for administration to the adequate points by 4-step method. Cautions: You need a sufficient experience and practice of proctology. 1) Follow to comply with 4-step method by dose and injection regions with 2% solution. 2) Avoid complications; the following points should be paid attention to. gProstatitis, epididymitis, orchitish gHemorrhoids necrosish gPain of the anush gindurationh gRectal ulcer/ necrosish gRectal stenosish etc. 3) Appearance rate of adverse reactions occurred in 19% in OC-108 group at phase III protocol and 10. 25% (462cases in 337/3287) at PMS of ALTA. 70 of ALTA Injection: ALTA Injection is directly administered into hemorrhoids by the 4-step method. Since this procedure is important for the efficacy and safety of ALTA Injection therapy, and you need a sufficient experience and practice of proctology. Efficacy and Results of ALTA Injection Therapy: ALTA Injection is effective for prolapse, the main symptom of developed hemorrhoids, which were previously surgically treated. In the phase III study, verification of the efficacy of ALTA Injection on prolapsed hemorrhoids and a survey of surgery (MilliganMorgan hemorrhoidectomy) was performed and the outcomes were compared. Disappearance rate of prolapse on the 28th day, recurrence rate in 1 year after treatment and postinjection complications were checked. As for hemorrhage, ALTA Injection exhibited a high effect earlier than surgery. Release from prolapse is similar to surgery. The mean duration of hospitalization was shortened, compared to surgery. However the recurrence rate 1 year after ALTA administration was 16%, mainly occurred in cases of third degree hemorrhoid of Goligher classification, and some abnormalities were reported. Summary: Sclerosing therapy with ALTA Injection was evaluated, effective and useful treatment in patients with prolapsed internal hemorrhoids. P013 XANTHOGRANULOMATOUS INFLAMMATION OF COLON: TWO CASES REPORT, SH Jung MD, JS Hwang MD, HJ Kim MD, JH Lee, JH Kim, MC Shim, Department of Surgery, College of medicine, Yeungnam University, Daegu, Korea Xanthogranulomatous inflammation(XGI) is chronic inflammatory condition that characterized by aggregation of lipid-laden foamy macrophages (xanthoma cells). This entity was first described by Christensen and Ishak in 1970 and has attracted particular attention in recent years, especially regarding the clinicopathological aspects. Clinically, it can be difficult to differentiate from infiltrative cancer because XGI might be presenting as an irregular mass-like lesion with a severe extension of fibrosis and inflammation to the surrounding tissues, and thus, often mimics infiltrative cancer. This disease entity is well recognized in the kidney and gallbladder, and three cases for the involvement of colon have reported. We report two cases XGI involving colon considering for diagnostic & therapeutic challenge. One, a 55-year-woman presented fever, right lower abdominal painand mass was revealed huge masslike lesion with severe infilteration on CT scan. Enbloc resection (right colon, abdominal wall, retroperitoneal soft tissue, ovary and lateral femoral nerve) was performed and finally, cecal cancer (T3N0M0) with XGI was confirmed. She suffered from right thigh flexion limitation for 6 months, postoperatively. Two, a 66-yearman presented fever, upper abdominal mass during 10 days was revealed infilerative T-colon malignant mass on CT, barium enema and PET. The T-colon mass with severe adhesion to upper abdominal organs was identified and transverse colectomy was performed. Finally, XGI originated from transverse colon serosa was demonstrated and he suffered from postoperative pancreatitis for 20 days. XGI may rarely arise in the large bowel. However, like gallbladder and kidney, XGI could be clinically and radiologically misinterpreted as an infiltrative cancer and is indistinguishablefrom inflammatory colon lesions with/or perforation. Therefore, any excessive operative stress and morbidity are difficult to avoid and need diagnostic and therapeutic challenges. P015 THE INFECTED MUCINOUS CYSTADENOMA OF APPENDIX MISDIAGNOSED INTRA-PELVIC ABSCESS, Ji Hoi Koo PhD, Sung Hoon Yang MD, Dept. of Surgery, Incheon Medical Center, Incheon, Korea Appendiceal mucinous cystadenoma is a rare entity found in only 0.3% of appendiceal specimens. It is the most classification of what has been generally termes ¡°mucocele¡± of the appendix. A mucocele of the appendix is an obstructive dilatation of the appendix caused by intraluminal accumulation of mucoid material. It may caused by 1 of 4 processes: retention cyst, mucosal hyperplasia, mucinous cystadenoma, or mucinous cystadenocarcinoma. The most presenting symptom has been abdominal pain, however, one-fourth of patients are asymptomatic and are found incidentally. Other reported symptoms are bleeding, intussuseption, and local invasion into surrounding structures are described. But the abscess formation of the mucinous cystadenoma is extremely rare. A 80-year-old women presented with a 3-days history of pain in the right lower quadrant of the abdomen. On physical examination, tenderness and rebound tenderness were checked, and palm-sized mass was palpable in the right lower abdomen. Computed tomography presented a huge intra-pelvic abscess measuring 110 X 113 mm. At laparotomy a huge infected cystic mass involved cecal wall of appendix was found, and an right colectomy was perfomed. The final pathologic diagnosis was atypical mucinous cystadenoma consistent with borderline mucinous neoplasm with inflammation. The patient was discharged at 10th post-operated day without any complications. P014 ZION E ( A LTA ) I N JEC TI O N TH E R A P Y F O R HEMORRHOID & PROLAPSE ZIONE: A NOVEL SCLEROSING AGENT OF ALUMINUM POTASSIUM SULFATE AND TANNIC ACID(ALTA) FOR HEMORRHOID AND PROLAPSE, Mitsuyo Kosugi MD, Takashi Ono, Toshiro Ono, Chief of Proctology Center, Saitoh Clinic, Toyama, Japan The ZIONE (ALTA) is a novel sclerosing agent, and ALTA Injection therapy for prolapsed internal hemorrhoid shows good results compared with surgery, Milligan-Morgan hemorrhoidectomy. What is ALTA? The ALTA is a novel sclerosing agent with aluminum potassium sulfate and tannic acid and an abbreviation of it as active components, which was the Xiaozhiling in China researched and modified by Mitsubishi Tanabe Pharma. Corporation, Japan. Mechanism and Fundamental Examination of OC-108, ALTAThe main component, aluminum injection into hemorrhoids controls bleeding by reducing blood flow and induces acute inflammation. Repairing reactions post-inflammation scleroses hemorrhoids and resolves prolapsed hemorrhoids. Tannic acid inhibits excess acute inflammation induced by aluminum potassium sulfate, and reduces secondary tissue injury. Fundamental studies in rats by microscopic observation show that all blood flow arrest within 10 minutes and without conspicuous change in blood vessel diameter by OC-108 (phase III protocol solution of ALTA). And repairing reactions post-inflammation shows that formation of fibrosis and epithelioid granuloma in hist-pathological examination. Methods P016 ZIONE (ALTA) INJECTION THERAPY FOR HEMORRHOID & PROLAPSE: OUTCOME OF SCLEROSING THERAPY BY THE ALTA INJECTION: PHASE III PROTOCOL AND POST-MARKETING SURVEILLANCE (PMS), Mitsuyo Kosugi MD, Hiroyuki Irie, Toshihiro Ono, Takashi Ono, Chief of Proctology Center, Saitoh Clinic, Toyama, Japan Phase III Protocol and Post-Marketing Surveillance (PMS): We show the outcome of sclerosing therapy by the OC-108 (clinical study solution of ALTA for Phase III Protocol) and PMS of ALTA after 3 years marketing in Japan. Phase III Protocol: Aims: Patients with prolapsed internal hemorrhoids were treated with OC-108 and results were compared with surgery. Objectives: Patients were studied by OC-108(n=105) and surgery group (n=87) during Oct. 2000-Oct. 2002 by totally 16 coloproctology surgeons in Japan. Results and Conclusion: 1) OC-108 was effective for bleeding at defecation early after treatment. 2) The recurrence rate 1 year after treatment was 16% (12/73 OC-108 group). 3) Hospital stay (mean) was 3.6 days, shorter than 10.9 days in surgery group. 4) Some adverse reactions occurred in 19%in OC-108 group. PMS: Objectives and Surveillance: Patients(n=2500) with prolapsed internal hemorrhoids, treated by ALTA Injection were surveyed by central registration and prospective method during March, 2005 to March, 2007 at Pharmacovigilance & Quality Assurance Division of Pharmacovigilance Department, Mitsubishi Tanabe Pharma Corporation. Injection Dose: Injection dose was <=20mL (64%), ISUCRS XXII BIENNIAL CONGRESS ABSTRACT BOOK Poster Papers <=40mL (34%) for second degree (24%), third degree (67%), forth degree (7.6%) hemorrhoid in Goligher classification. Results and Conclusion: 1) ALTA injection was effective for prolapse in 98.2% at evaluation time of 28 days after injection. 2) The recurrence rate more than 2 years after treatment was 5.6% (2/36 in the second degree), 17.3% (26/156 in the third and forth degree) and totally 15% (28/192). 3) Appearance rate of adverse reactions occurred in 10. 25% (462cases in 337/3287). Summary: Sclerosing therapy with ALTA Injection was evaluated, effective and useful treatment in patients with prolapsed internal hemorrhoids to a similar extent as surgery. It is spreading in nationwide in Japan as an important treatment for hemorrhoids and used for more than fifty thousand cases. P017 INCIDENCE OF RECTAL PROLAPSE AND OUR EXPERIENCE IN DELORME’S OPERATION, Dr. Ponniah Sivalingam MS, Dr. K. S. Mayilvaganan MS, Dr. . Vadamalayan Sivalingam MD, Dr. Sabaretnam Mayilvaganan MS, Governmet Rajaji Hospital and Vadamalayan Hospitals, Madurai, India Many operative procedures were reported for the treatment of rectal prolapse which perhaps indicated unsatisfactory result. Search is on for a better one. The experience with 111 operations performed with Delorme’s surgical technique is presented here. Between January 1983 and September 2007, 214 patients reported with complete rectal prolapse at Govt. Rajaji Hospital and as private patients of authors. One hundred and thirty six patients were below 41yrs. The youngest patient was girl of 12yrs and oldest a woman 85yrs. Male/ Female ration was 3: 1. All 214 patients presented with a complaint of mass protruding through the anus. Mucous discharge was present in 50 (23. 36%) bloody discharge in 47 (21. 9%) pruritus ani in 20 (12. 1%) and constipation in 12 (5. 6%). Of these141 patients were operated, 111 Delorme and 28 per abdomen (Roscoe - Grahams Repair 24: Charles Wells Ivalon sponge technique -4) and perineal rectosigmoidectomy -2. Of 111 cases operated by Delorme’s procedure, 77 patients were below 41years. Pre operation preparation surgical technique and post operative care will be discussed. Post operative complications were encountered in 18 out of 111 operated cases. Two had secondary haemorrhage and four had infection (Collection of pus in the submucous plane of rectum). In 6 cases there was gross stenosis. Recurrence has occurred in 6 cases. Discussion: In our series the occurrence of complete rectal prolapse in males versus females was 3. 4: 1 which is in fair contrast to Western reports of 1: 6. In the Western countries prolapse rectum is a disease of the old in the 6th decade, where as we found 63. 6 our patient below 40yrs. Constipation, a common symptom in western reports was present only in 12 cases (5. 6%) of our cases. Delorme’s operation is a simple procedure, which gives comparable results as of abdominal operations advised for prolapse. Presacral dissection to mobilize the rectum from the sacral curvature either per abdomen or by perineal route may cause damage to the nerves resulting in bladder and sexual dysfunction. Conclusion: The incidence of prolapse is more in male, it occur more in the younger age (below 40 years) and so a surgery which does not require the pre sacral dissection is more desirable. Constipation associated with prolapse is only 5. 6% of cases. P018 PERIPARTUM DIVERTICULITIS- A HORMONAL CAUSE?, E D Wietfeldt MD, Jan Rakinic MD, Southern Illinois University Dept. of Surgery, Section of Colorectal Surgery Question: Colonic diverticulitis is uncommon in the peripartum period, with fewer than five cases reported in the English literature. Therefore, when we were faced with this problem twice in the same patient, questions were raised about possible causes and safest therapy. Our patient had two episodes of uncomplicated diverticulitis during two separate peripartum periods, but has not had any related symptoms at any other time. This raised questions about the possible effects of pregnancy on diverticulosis. Constipation is a common complaint during late pregnancy. Female sex hormones exert significant influence on intestinal function. Fluctuations in intestinal transit time (TT) can be related to the human menstrual cycle. The longest TT is shown to be during the luteal phase, when progesterone is high, as it is during pregnancy. Progesterone decreases colonic muscle contraction by a regulatory effect on G proteins. When treated in vitro with progesterone, normal human colonic myocytes exhibit www.isucrs.org/ down-regulation of the contractile G-alpha q and G-alpha i proteins and up-regulation of G-alpha s proteins which mediate relaxation. Overexpression of progesterone receptors appears to be a key component. This is similar to observations in women with chronic constipation. The oxytocin-mediated inhibition of colonic muscle contraction in the rabbit colon via generation of nitric oxide is also potentiated by progesterone. We postulate that the effects of both progesterone and oxytocin may contribute to increased constipation during pregnancy and the peripartum period. With an increasing number of women bearing children in their 40s, we postulate that this could lead to an increased, although still small, incidence of diverticulitis in the peripartum period. We urge physicians to include this entity in the differential diagnosis when evaluating peripartum women with lower abdominal pain. We also urge proper fluid intake and fiber supplements in pregnant women in an attempt to keep the diverticulitis risk from constipation at a minimum. P019 RECTAL PROLAPSE TREATMENT - THE CHOICE OF TECHNIQUE, Bruno Roche MD, Karel Skala MD, Guillaume Zufferey MD, Joan Robert-Yap MD, Unit of Proctology, University Hospital of Geneva Introduction: Over 160 different procedures have been described to treat rectal prolapse. Recent studies favor anterior fixation over simple posterior rectopexy. In our institution the gold standard operation consists of a laparoscopic posterior dissection with simple suture fixation of the rectum. From January 2003 to December 2006 we performed a comparative randomized study between posterior rectopexy without mesh (PR) and anterior mesh promonto-fixation (AMP). Inclusion criteria: patient consent to participate in the study, female with total rectal wall perineal prolapse, clinical signs and defecography or MRI imaging. Exclusion criteria were recurrent prolapse, emergency situations, associated utero-vaginal prolapse and/or bladder prolapse. Material and Methods: We included 53 patients in group PR, median age 69. 2 y (34-94) and 53 patients in group AMP, median age 69. 4 y (20-96). 26 patients in PR and 27 in AMP had a previous hysterectomy. Results: Median operative time was 94min for PR and 132min for AMP with a difference of 38 min. Surgical approach was open in 2 patients PR and 6 patients in AMP; laparoscopy for the other procedures. Conversion rate was 1 per group. Complications- PR (1. 9%): 1 bleeding of the presacral veins with conversion, AMR (5. 7%): 1 parietal haematoma, 1 anterior rectal perforation with re-operation on day 2 (Hartmann), 1 small gut laceration with peritonitis and re-operation on day 1. Recurrences at one year after the procedure were 1 in PR, and 2 in AMP. Conclusion: Simple rectopexy (PR) with sutures is a safe and quick procedure. Complications are rare (1. 9%), with no reoperations. Promontofixation (AMP) leads to a longer operating time and more complications (5. 7%) with 2 re-operations. There is no need for a mesh when not indicated. Colorectal Cancer P020 HYPERPLASTIC POLYPS OF THE RIGHT AND LEFT SIDE OF THE COLON: IS THERE A DIFFERENCE IN THE MOLECULAR PATHWAY?, M Oviedo MD, J Carrozzo MD, M Cruz-Correa MD, Dana Sands MD, E Weiss MD, J Nogueras MD, S Wexner MD, M Berho MD, Cleveland Clinic Florida Introduction: DNA hypermethylation is described in SA and sporadic MSI-H CRC. DNA hypermethylation translates in loss of expression of the MLH gene protein product. This alteration may occur in HP although its frequency is unknown. Although no malignant potential has been ascribed to HP there is some evidence that on occasion these “innocent” polyps could be the precursors to adenocarcinoma. Objectives: The purpose of this study was to compare the differential expression of a set of morphological and immunohistochemical properties between HP polyps of the right and left side. Material and Method: 75 patients with hyperplastic polyps, diagnosed between 2005 2006 were selected retrospectively from a pathology database. The polyps were divided according to the location into right and left side of the colon. The following histomorphological parameters were recorded: size, thickness, serration, dilatation, basal membrane thickness, nuclear stratification, goblet cell, nuclear atypia and apoptosis. Paraffin blocks were cut and 71 ABSTRACT BOOK Poster Papers stained by immunohistochemical techniques for hMLH1 and hMSH2, CEA and Ki 67. Results: A total of 99 polyps were obtained. The average age was 59. 5 years and a mean of 1. 45 polyps per patients. Right-sided polyps have increased thickness more glandular dilatation and more nuclear stratification when compared to left sided polyps. There was no difference noted for either intensity or distribution when samples were stained by any of the functional markers. Conclusion: Right and Left sided HP are distinguishable on basis of morphological features identified through examination of routine diagnostic slides but do not differ with respect to potential functional markers usually associated with malignant neoplasms suggesting that when strict morphological criteria are applied right sided hyperplastic polyps may not be different from left side polyps. P021 NEO-ADJUVANT RADIOTHERAPY FOR LOCALLY ADVANCED RECTAL CANCER: DOES IMRT(INTENSITY MODULATED RADIATION THERAPY) IMPROVE OUTCOMES AS COMPARED TO 3-D CONFORMAL RADIOTHERAPY?, Hao Wang MD, Bashar Safar MD, Steven D Wexner MD, Badma Bashankaev MD, Dana Sands MD, Juan Nogueras MD, Eric Weiss MD, Mariana Berho MD, Christopher Chen MD, Cleveland Clinic Florida Purpose: Neoadjuvant radiotherapy may adversely affect anal function after restorative proctectomy or low anterior resection. The recently developed IMRT technique applies more fields than traditional 3D technique. It delivers the same radiation dose to the rectal cancer and pelvis and spares the adjacent organs, mainly small bowel and bladder. The aim of this study is to investigate whether IMRT has any sphincter sparing effects in addition to its other advantages. Methods: From 1998 to 2007, patients with primary rectal carcinoma and standard neoadjuvant therapy were identified. The neoadjuvant therapy consisted of a total dose of 50. 4Gy of radiation and 5-Fu based chemotherapy. The tumor regression grade(TRG) was identified by reviewing postoperative pathological slides(TRG1-5: TRG1 = complete pathological response and TRG5 = no response). The anal function was assessed for the cases with coloanal anastomosis by the Cleveland Clinic Florida Fecal Incontinence Score(CCF - FIS) and evacuation parameters by telephone questionnaire. Statistical analysis was performed using Mann-Whitney Test and Student’s T-test. Results: A total of 114 patients were identified including 33 cases in the IMRT group (starting from 2003) and 81 cases in the 3D group. There were no significant differences in either TRG (P=0. 785, n=114) or in lymph node harvest between the IMRT and 3D groups (P=0. 475, n=64). Forty-four patients (16 cases in IMRT group and 28 cases in 3D group) answered the anal function questionnaire with a mean follow-up of 17months (range, 2-52). The follow-ups between two groups were similar (P=0. 640). There were no significant differences in either fecal incontinence scores (P=0. 293) or evacuation scores (P=0. 293). IMRT resulted in less alteration in life style (component of FIS) compared with 3D (P=0. 038) and was also associated with tendency to have fewer bowel movements (P=0. 057), which may indicate better small bowel function. Conclusions: IMRT had similar therapeutic outcomes as 3D. Moreover, IMRT had minimal advantage over 3D with respect to anal sphincter preservation and function. Further prospective research is warranted. P022 DIFFERENTIAL EXPRESSION OF MLH1 AND MSH2 PRODUCTS IN ADENOCARCINOMAS OF THE LEFT AND RIGHT COLON, M Oviedo MD, R Mather MD, H Wang MD, D Sands MD, E Weiss MD, S Wexner MD, J Nogueras MD, M Berho MD, Cleveland Clinic Florida Mucinous adenocarcinoma (MA) is a histologic subtype of colorectal carcinoma characterized by pools of extracellular mucin representing more than 50 % of the tumor body. It accounts for 10 to 15% of colorectal carcinomas and appears to occur more often in the right colon and rectum than other parts of the colon. Mucinous carcinomas are commonly seen in hereditary nonpolyposis colorectal cancer (HNPCC) associated tumors as well as in sporadic colorectal neoplasms showing microsatellite instability (MSI). The hallmarks of HNPCC are abnormalities in the mismatch repair gene products MLH and MSH and others. Expression of these proteins and underlying molecular pathways in mucinous carcinomas that occur outside the setting of HNPCC has not been 72 ISUCRS XXII BIENNIAL CONGRESS clearly defined. Aim: To evaluate the differential expression of MLH1 and MSH2 products in adenocarcinomas of the left and right colon. Material and Methods: After IRB approval, 45 consecutive patients with mucinous carcinomas were identified retrospectively from a pathology database. Twenty-three cases correspond to the right colon and 22 cases from the left colon. Paraffin blocks were selected and stain with antibodies against MLH and MSH. Results were being scored as positive, negative or equivocal. Cases with negative or equivocal were evaluated for, BRAF-1 mutation and hypermethylation of the MLH1 promoter. Patients fulfilling criteria for FAP and HNPCC were excluded. Results: Females represented 51. 1 % of the cases. The mean age was 57 years in the group from the right sided tumors and 67 years in the patients from the left (p< 0. 02). Pathological TN stage was not significant different between right and left side tumors. All tumors stained with MSH. Overall, MLH1 protein expression was absent in 14 of 45 carcinomas (31. 1%), 8 from the right and 6 from the left colon, five of the 8 right side tumors (62. 5 %) and 1/6 cases (16. 6%) of the left side tumors showed hypermethylation of the MHL promoter and BRAF mutation. Conclusion: Loss of MLH expression was not significantly different in right vs left side tumors; however hypermethylation of the MLH promoter and Braf-1 mutation appears to be more common in right side lesions compared to the left side tumors. Although the significance of this finding is unclear, the possibility of different molecular pathways between right and left side lesions that result in loss of MLH expression needs to be considered. P023 EFFICIENCY OF SENTINEL LYMPH NODE BIOPSY FOR ULTRA-STAGING OF COLORECTAL CANCER PATIENTS, Masayoshi Miyoshi MD, Yojiro Hashiguchi MD, Hideki Ueno MD, Yoshiki Kajiwara MD, Hidetaka Mochizuki MD, Surgery 1, National Defense Medical College Purpose: Accurate staging of colorectal cancer patients is prognostically and therapeutically important to identify those patients who would most benefit from adjuvant chemotherapy. Lymphatic mapping and sentinel node analysis enable a focused review of the lymph nodes which are most likely to harbor metastases. It may be feasible to apply ultra-staging techniques, such as immunohistochemistry to sentinel lymph node (SLN). The aim of this study is to evaluate efficiency of sentinel lymph node biopsy (SLNB) to detect nodal micrometastases of colorectal cancer. Methods: Between 2000 and 2004, twentyseven colorectal cancer patients who underwent curative surgery and SLNB, were diagnosed as no nodal metastasis based on hematoxylin-eosin stained specimen. A total of 624 lymph nodes from the 27 patients were examined to detect micrometastases by immunohistochemistry. About SLNB, Indian ink was injected intraoperatively to 3 patients, and 99mTc Tin colloid was injected 20-24 hours before operation to 24 patients. Five 4-micrometerthick serial sections were obtained from each lymph node. One section was stained using the hematoxylin-eosin method for routine histopathological examination and the other four sections further stained for AE1/AE3 anti-cytokeratin antibodies. We defined micrometastases as metastases not detectable by routine histological examination with hematoxylin-eosin staining but detected by immunohistochemistry evaluation with AE1/AE3. Results: There were 15 colon cancer patients and 12 rectal cancer patients. A total of 98 SLNs were harvested (3. 6 SLNs per a patient). Micrometastases were detected by immunohistochemistry in 8 lymph nodes (8/623, 1. 3%) from 6 patients (6/27, 22. 2%). Of all 8 micrometastatic lymph nodes, 7 nodes were SLNs and one was non SLN (87. 5% vs. 12. 5%, p=0. 010). Conclusions: Majority of micrometastatic lymph nodes were included to SLNs. SLNB may be a useful technique to efficiently detect micrometastases for ultra-staging of colorectal cancer. P024 INTERSPHINCTERIC RESECTION WITH QUADRANT RESECTION OF UPPER EXTERNAL SPHINCTER IN CASES OF THE VERY LOW RECTAL CANCER, Nahmgun Oh PhD, Hyuk-Jae Jung MD, Hyunsung Kim MD, Department of Surgery, Pusan National University Hospital, Busan, South Korea Purpose: In the treatment of rectal cancer, sphincter saving operation is increased but low anterior resection is limited in treatment for low rectal cancer situated below 4cm from the ABSTRACT BOOK Poster Papers anal verge. In other reports intersphincteric resection for T2 cancer can allow an oncologically safe resection margin and have good functional results in very low rectal cancer. The purpose of this study is to evaluate the morbidity, mortality, oncological and functional results of intersphincteric resection for T2 and T3 rectal cancer situated below 4cm from the anal verge. Methods: Between 2000 and 2004, 62 patients (mean age 52 years, range 34-74) with adenocarcinoma of the rectum underwent abdomino-intersphincteric resection with a colonic J-pouch and diverting ileostomy. After preoperative radiochemotherapy, patient with overt T2 lesion was 24 cases and received traditional intersphincteric resection (Group I: simple intersphincteric resection), and patient with borderline cases or T3 lesion was 38 cases and received extended intersphincteric resection with quadrant resection of upper external sphincter and primary repair of the external sphincter(Group II: extended intersphincteric resection). Results: The mean distance between the tumor and anal verge was 3. 4 (range 2. 4-4. 0) cm. Over 3mm lateral surgical margin was 79. 1%, 84. 2% of Group I and II. 1 case of inferolateral recurrence(4. 0%) was occurred in Group I and 1 case of pelvic recurrence(2. 6%) in Group II. Systemic recurrence was 2 cases(8. 3%), 3 cases(7. 9%) in Group I and II. Perineal wound infection was 25. 0%, 26. 3%, and mild anastomotic stricture was 25. 0%, 26. 3% in Group I and II. The grade I, II of continence by Kirwan classification was 83. 3%, 81. 5% in Group I and II. Under 3 times stool frequency per day was 54. 2%, 63. 2% in Group I and II. There was no postoperative mortality. P025 OPTIMAL LIGATION LEVEL OF THE PRIMARY FEEDING ARTERY AND BOWEL RESECTION MARGIN IN COLON CANCER SURGERY: THE INFLUENCE OF THE SITE OF THE PRIMARY FEEDING ARTERY, Jin-ichi Hida MD, Takehito Yoshifuji MD, Fumiaki Sugiura MD, Masako Takemoto MD, Takashi Hattori MD, Kazuki Ueda MD, Eizaburou Ishimaru MD, Tadao Tokoro MD, Masayuki Yasutomi MD, Hitoshi Shiozaki MD, Kiyotaka Okuno MD, Department of Surgery, Kinki University School of Medicine, Osaka, Japan Purpose: In colon cancer surgery, it is recommended that en bloc resection involving extended lymphadenectomy, characterized as a hemicolectomy, be performed by ligating the primary feeding artery at a high position and resecting proximal and distal with 5-cm to 10-cm bowel margins. However, there is little evidence to unequivocally support such extensive lymphovascular resection. Methods: The distribution of nodal metastases was obtained by the clearing method in 164 patients with colon cancer. Results: For pericolic spread, for pT1 tumors, the distance from the primary tumor to a diseased node was 2. 5cm; for pT2, the distance was less than 5cm; for 97. 0% of pT3 tumors and 93. 3% of pT4 tumors with nodes involved, the distance was less than 7cm. For central spread, for pT1 tumors, the rate of spread to central nodes was 0%; for pT2, the rate of spread was 20. 0% to intermediate nodes (for tumors more than 5cm from the feeding artery, the rate for central nodes was 0%); for pT3, the rate was 30. 6% to intermediate nodes and 15. 3% to main nodes; for pT4, the rate was 44. 4 % to intermediate nodes and 22. 2% to main nodes. For curative resection cases with pT3 tumors more than 7cm from the feeding artery, the rate to central nodes was 0%. Conclusions: In T1 tumors, central node dissection is not required, but resection with proximal and distal 3-cm margins are required; in T2, central node dissection that includes the intermediate node should be performed in addition to resection with proximal and distal 5-cm margins. In T3 and T4, central node dissection that includes the main node should be performed in addition to resection with proximal and distal 7-cm margins. However, for T2 more than 5cm from the primary feeding artery, and for T3 more than 7cm from the primary feeding artery, proximal and distal resection alone may be adequate. P026 VALUE OF INTRAOPERATIVE SENTINEL MAPPING, Krasimir Ivanov MSc, Valentin Ignatov PhD, Nikola Kolev PhD, Anton Tonev MD, University Hospital “St. Marina”, Medical University - Varna, Bulgaria Background/Aims: The presence of metastasis is the most important prognostic factor for the patients with colorectal cancer. In about 30% of those without metastases which have been radically operated recurrences are observed and these patients die www.isucrs.org/ from cancer. This requires improvement of the surgical methods as well as a more accurate determination of the indications for adjuvant chemotherapy administration. Material and Method: Between August 2004 and April 2007 we assigned 472 consecutive patients with colorectal cancer. We applied routinely the method intraoperative sentinel mapping in 336 patients that intraoperavely was evaluated as I and II clinical stage. We used the dying method with Patent Blue V. An algorithm, proposed and applied by us was worked out for the entire group of patients. Results: The 159 men and 177 women had a median age of 62 years. Localization was spread as 172 patients with colon carcinoma and 164 with rectum carcinoma. The median number of SNs and total lymph nodes examined were 3 and 14. 5, respectively. The sensitivity of lymphatic mapping and SN analysis was 97% and the falsenegative rate was 3%. We increased the volume of the surgical intervention in 24 (7%) of the patients and upstaged 37 (11%) of patients by means of ultrastaging with immunohistochemistry. We followed a group 152 patients for a period of 2 year with recurrence incidence of 47 (14 %) of the patients. Conclusions: Intraoperative sentinel lymph node mapping in colorectal cancer is a diagnostic method which is convenient for the surgeons allowing them for an individualized approach toward each patient. The method shows good results and has its own significance for decreasing the recurrence rate and eventually increasing the survival rate in patients with colorectal cancer. P027 HEPATIC LYMPH NODE INVOLVEMENT IN PATIENTS WITH SYNCHRONOUS LIVER METASTASIS OF COLORECTAL CANCER, Keiichiro Ishibashi PhD, Kouki Kuwabara MD, Masatsugu Ishii MD, Toru Ishiguro MD, Tomonori Ohsawa PhD, Norimichi Okada PhD, Masaru Yokoyama PhD, Tatsuya Miyazaki PhD, Moriyuki Matsuki PhD, Hideyuki Ishida PhD, Department of Digestive Tract and General Surgery, Saitama medical Center, Saitama Medical University Background and Purpose: This study was performed to examine the status of hepatic lymph node metastasis in patients with synchronous liver metastasis of colorectal cancer, and to consider the significanceof the presence of metastasis in the treatment of those patients. Patients and Methods: Hepatic lymph nodes were removed from 61 patients (17: resectable, 44: unresectable) with synchronous liver metastases of colorectal cancer during resection of the primary tumor. The relationships between the incidence of hepatic lymph node metastases and various clinicopathological factors and overall survival were examined. Results: Hepatic lymph node metastasis was detected in three patients (18%) with resectable lesions and 13 patients (30%) with unresectable lesions. For the resectable cases, the serum level of CA 19-9 (p<0. 01), and the numbers of lymph node metastasis of the primary lesion (p=0. 08) were higher in patients with hepatic lymph node metastases (n=3) than in those without (n=14). There were no significant relationships between hepatic lymph nodes metastasis and other clinicopathological factors. The median overall survival for patients without metastasis was better than that for patients with metastasis (43 months vs 11 months, p=0. 06). For the unresectable cases, the serum level of CEA (p=0. 08) was higher in those with than in those without (n=31). The median overall survival for patients without metastasis was better than that for patients with metastasis (16 months vs 8 months, p=0. 04). There were no significant relationships between hepatic lymph nodes metastases and other clinicopathological factors, including the volume of liver metastases. Conclusion: The incidence of hepatic lymph node metastases should be considered in selecting the optimal treatment of liver metastases of colorectal cancer, regardless of the respectability of hepatic lesions. P028 SPHINCTER PRESERVING SURGERY IN PATIENTS WITH RECTAL CANCER LOCATED WITHIN LESS THAN 3 CM OF THE ANAL VERGE, S. -C. Park MD, D. -W. Kim MD, S. -Y. Jeong MD, J. -G. Park MD, Department of Surgery, Seoul National University Hospital, Seoul, Korea Aims: To evaluate the current status of sphincter preservation for distal rectal cancers located within less than 3 cm from the anal verge. Methods: Between January 2001 and December 2007, 120 patients underwent surgery for primary rectal adenocarcinoma located within less than 3 cm of the anal verge at the Department of Surgery, Seoul National University Hospital 73 ABSTRACT BOOK Poster Papers and the Center for Colorectal Cancer, National Cancer Center by single surgeon, J-G Park. Clinical data were retrospectively reviewed, including pathologic stages, operation types, and preoperative chemoradiotherapy (CRT). Results: Of 120 patients with rectal cancers located within less than 3 cm of the anal verge, 73 underwent preoperative CRT followed by surgery (CRT group), and 47 underwent surgery first (non-CRT group). Overall sphincter preservation rate was 38% (47/120 patients). In CRT group, sphincter preservation was 51% (37/73) and non-CRT group was 21% (10/47) (p = 0. 02). Operation types were transanal excision (n=9), low anterior resection with double-stapled anastomosis (n=2), low anterior resection with upper sphincter excision and colo-anal anastomosis (n=27), low anterior resection with intersphincteric resection and colo-anal anastomosis (n=9), and abdominoperineal resection (n=72). Recent 3 years, the sphincter preservation rate was 62% (31/50 patients). Combining preoperative chemoradiation and low anterior or intersphincteric resection with colo-anal anastomosis may contribute to increase the sphincter preservation rate. But this retrospective study is hard to analyze the effect of the each contributing factor for sphincter preservation. Conclusion: During 7 years, overall sphincter preservation rate was 38%, and recent 3 years the sphincter preservation rate was 62% for the rectal cancer located within less than 3cm from anal verge. P029 OUTCOMES OF LATERAL LYMPH NODE DISSECTION IN DUKES C LOW RECTAL CANCER, Harunobu Sato MD, Koutarou Maeda MD, Tsunekazu Hanai MD, Yoshikazu Koide MD, Hidetoshi Katsuno MD, Masuo Funabashi MD, Department of Surgery, Fujita Health University Purpose: This study was performed to identify patients who benefit from lateral lymph node dissection (LND) for Dukes C low rectal carcinoma according to the number, the side and the site of positive lateral node (PLN). Patients and Methods: The study comprised 146 patients with Dukes C low rectal carcinoma undergoing LND. Three parts of lymph nodes, area A, B and C, were dissected for grade T2 or more advanced tumors. The area A is corresponding to TME area. The dissection of area B (the space between autonomic nerve and internal iliac artery) and C (the obturator space) was defined as LND. The patients were retrospectively divided into two groups; patients without PLN (group I) and patients with PLN (group II). Furthermore, group II was subdivided into two groups respectively according to the number, the side and the site of PLN; group IIA1 (patients with less than 4 PLN) and group IIA2 (patients with more than 4 PLN), group IIB1 (patients with PLN in unilaterally) and group IIB2 (patients with PLN bilaterally), group IIC1 (patients with PLN in either area B or area C) and group IIC2 (patients with PLN in both area B and C). Clinical outcomes were studied in terms of recurrence and prognosis. Results: Recurrence (RR) and 5-year survival rate (5SR) were 37. 8% and 70. 3% in group I. RR rate and 5SR were significantly worse in group IIA2 (100% and 0%) than IIA1 (55. 8% and 46. 5%), in group IIB2 (93. 8% and 11. 2%) than IIB1 (54. 2% and 45. 7%), and in group IIC2 (90. 9% and 11. 2%) than IIC1 (50% and 50. 7%). Group IIA2, IIB2 and IIC2 were thought to be high risk groups for LR and poor prognosis. RR rate and 5SR were 44. 7% and 54. 2% in patients who do not belong to any high risk groups (group NR). Although RR rate and 5SR were significantly better in group NR than in patients who belonged to only one high risk group (92. 3% and 12. 3%), there were no significant differences in RR and prognosis between group I and NR. There was no 5-year survivor in patients who belonged to equal to or more than two high risk groups. Conclusion: LND for low rectal carcinoma was effective for patients with PLN in patients who do not belonged in any high risk groups. However, LND gave no survival benefit for patients who belonged to equal to or more than two high risk groups. P030 ANALYSIS OF REGIONAL LYMPH NODE METASTASES FROM RECTAL CARCINOMA BY THE CLEARING METHOD: JUSTIFICATION OF THE USE OF SIGMOID COLON IN J-POUCH CONSTRUCTION AFTER LOW ANTERIOR RESECTION, Jin-ichi Hida MD, Takehito Yoshifuji MD, Fumiaki Sugiura MD, Masako Takemoto MD, Takashi Hattori MD, Kazuki Ueda MD, Eizaburou Ishimaru MD, Tadao Tokoro MD, Masayuki Yasutomi MD, Hitoshi Shiozaki MD, Kiyotaka Okuno MD, 74 ISUCRS XXII BIENNIAL CONGRESS Department of Surgery, Kinki University School of Medicine, Osaka, Japan Purpose: It has been reported that functional outcome following low anterior resection of rectal cancer is improved by construction of a colonic J-pouch compared with straight anastomosis. Hence, we tried to justify use of the sigmoid colon in the construction of a J-pouch by the analysis of regional lymph node metastases. Methods: A total of 198 patients underwent resection for rectal cancer. Node metastases were examined by the clearing method. According to Japanese General Rules (JGR), nodes were classified into the perirectal nodes (PR-N), pericolic nodes (PC-N), central intermediate nodes (C-IM-N), central main nodes (C-M-N). Results: Metastatic rate (number of patients with node metastases/total number of patients) of PR-N was 56. 6%. Metastatic rate of C-IM-N was 19. 2% and that of C-M-N was 8. 6%. Metastatic rate of PC-N was only 1. 0%. Conclusions: In low anterior resection, high ligation of the inferior mesenteric artery and dissection of C-M-N, C-IM-N and PR-N are necessary. Resection of sigmoid colon is not required, and therefore, a J-pouch can be constructed using the sigmoid colon. P031 SHORT TERM RESULTS OF LOWER RECTAL CANCER ACCORDING TO PROCEDURE, Toshimasa Ishii MD, Shigeki Yamagutchi MD, Jo Tashiro MD, Takahiro Sato MD, Syutarou Ozawa MD, Yoshihide Otani MD, Isamu Koyama MD, Saitama Medical University International Medical Center Purpose: Since April 2007 of hospital opening, we tried to perform intersphincteric resection (ISR) and laparoscopic resection (Lap) for lower rectal cancer. This study was assessed short term results for recent 10 months. Patients: Nineteen patients of curative lower rectal cancer resection were included in this study. There are 13 males and 6 females. Each number of procedure was; low anterior resection (LAR) 6, ISR 5, Abdomino-perineal resection (APR) 8. Five patients underwent lapraoscopic resection and 12 patients received lateral lymphadenectomy (LLA). All cases of LAR and ISR had diverting stoma. Results: Mean operating time, mean blood loss count, and mean postoperative hospital stay were LAR 291min., 204g, 10. 8days, ISR 400min., 387g, 11. 4days, APR 332min., 501g, 19. 7days, respectively. Regarding postoperative complication rates, anastomotic leakage, intestinal obstruction, and wound infection were LAR 0%, 20%, 0%, ISR 0%, 20%, 0%, APR 0%, 22%, 33%. There were no difference of postoperative complications between open and Lap in LAR and ISR. However mean postoperative hospital stay and mean blood loss count were 12. 2days, 419g in open and 10. 0days, 172g in Lap. Lap was shorter hospital stay and less blood loss than open resection. Conclusion: Short term results of ISR were similar to that of LAR, and wound infection was seen more in APR. Lap was less invasive than open resection concerning hospital stay. P032 VARIOUS APPROACHES TO TREATMENT OF PATIENTS WITH THE COMPLICATED CURRENT OF A CANCER OF THE LEFT HALF OF LARGE INTESTINE. , S. V. Vasilyev, D. E. Popov, A. V. Semenov, V. A. Kiselev, St. Petersburg State Pavlov’s Medical University, Center of Coloproctology, St. -Petersburg, Russia The purpose. To estimate experience of surgical treatment in patients with colorectal cancer complicated with intestinal impassability. Materials and Methods: 240 patients with obstructing left colonic and rectal cancer were operated in period of last 5 years. All patients were divided into three groups depending on the degree of expressiveness of intestinal impassability: compensated, subcompensated and decompensated. To all patients have been executed various surgical interventions: diverting colostomy (laparoscopic or from miniapproach) - 32; obstructive resection of large intestine with a tumor - 115; subtotal colectomy - 21; primary - reconstructive resections of large intestine with use of the technique of intraoperative intestinal lavage - 72. Results: Various complications were developed in 25%. Mortality has made 3, 2%. In 95 cases (39, 6%) the intestinal continuity is restored primarily. Anastomotic leakage was not in one case. All patients with preliminary formed diverting stomas operated in the scheduled order in two-four weeks. Conclusion: The choice of operative intervention depends on localization of ABSTRACT BOOK Poster Papers the tumor, prevalence of tumor process, the general condition of the patient and degree of expressiveness of intestinal impassability. Use of the set for intraoperative irrigation of large intestine, which realization occupies about 20-50 minutes, relieves of necessity to provide any multistep surgeries. P033 STANDARDIZED LAPAROSCOPIC INTRACORPOREAL RIGHT COLECTOMY FOR CANCER: SHORT-TERM OUTCOME IN 111 UNSELECTED PATIENTS, A D Dippolito MD, R Bergamaschi MD, Lehigh Valley Hospital, Allentown, Pennsylvania Objectives: This study was performed to evaluate the impact of a standardized laparoscopic intracorporeal right colectomy on short-term outcome of patients with neoplasia. Method: Consecutive patients with histologically proven right colon neoplasia underwent standardized laparoscopic intracorporeal right colectomy with medial-to-lateral approach encompassing ten sequential steps: 1) ligation of ileocolic vessels, 2) identification of right ureter, 3) dissection along superior mesenteric vein, 4) division of omentum, 5) division of right branch of middle colic vessels, 6) transection of transverse colon, 7) mobilization of right colon, 8) transection of terminal ileum, 9) ileocolic anastomosis, 10) delivery of specimen. Values were medians (range). Result: From January 2002 to June 2005, 111 laparoscopic intracorporeal right colectomies were attempted with a 5. 4% conversion rate. 57 women and 54 men aged 64. 9 (40-85) years had BMI 33 (2043), ASA score 2 (2-4), 36. 9% co-morbidities, and 37. 8% previous abdominal surgery. Indication for surgery was cancer in 109 patients. Operative time was 120 (80-185) minutes. Estimated blood loss was 69 (50-600) ml. Overall skin incision length was 66 (60-66) mm. 29 (2-41) lymph nodes were harvested. Length of stay was 4 (2-30) days. Complication rate was 4. 5%. Conclusion: Standardized laparoscopic intracorporeal right colectomy resulted in favorable short-term outcome in unselected patients with neoplasia of right colon. P034 A CASE OF ASCENDING COLON CANCER IN A PATIENT WITH HYPERPLASTIC POLYPOSIS OF THE COLON, Kazuhito Sasaki MD, Giichiro Tsurita PhD, Shinsuke Saito PhD, Hirokazu Tsuno PhD, Hirokazu Nagawa PhD, Department of Surgical Oncology Graduate School of Medicine, The University of Tokyo Here, we report a case of ascending colon cancer, which was suspected to be originated from hyperplastic polyposis, and describe the genetic and histopathologic findings. The patient was a 75-year-old man, without familial history of colonic diseases. He had a past history of surgical treatments for appendicitis and cholelithiasis. The colonoscopic examination at 55-year age revealed no abnormalities. Complaining of abdominal pain and diagnosed as anemy, he was introduced to our surgical department for investigation. Colonoscopy revealed type 2 tumor of the ascending colon, occupying all the luminal circumference. The histopathology revealed well-differentiated adenocarcinoma. Multiple hyperplastic polyps, as well as tubular and serrated adenomas were found in the total colon. Distant metastases were not found by CT. Subtotal colectomy and ileo-sigmoid colon anastomosis was indicated, in an attempt to preserve the anal sphincter function. The polyps of the remaining colon were colonoscopically removed immediatly after the operation. The removed specimes were genetically, immunohistochemically and histopathologically analyzed, and will be presented. P035 RETROSPECTIVE ANALYSIS OF PATIENTS TREATED WITH CETUXIMAB PLUS FOLFIRI FOR PREVIOUS IRINOTECAN COMBINED CHEMOTHERAPY IN METASTATIC COLORECTAL CANCER, Park Jae Woo MD, Moon Sun-Mi MD, Hwang Dae-Yong MD, Korea Cancer Center Hospital Purpose: Many reports about the cetuximab efficacy of the prolongation of survival rate has been published. Especially, the combination of cetuximab and FOLFIRI has a high activity even in prior irinotecan refractory mCRC. Beside small number of patients, we would evaluated the efficacy and safty of cetuximab combined with FOLFIRI prior irinotecan chemotherapy failure patients. Methods: Retrospective analysis of 26 patients treated with cetuximab with FOLFIRI from July 2006 to August 2007 was done. All patients were already treated wth FOLFIRI www.isucrs.org/ chemotherapy in 1st line or 2nd line regimen for mCRC. Initial dose of cetuximab 400 mg/m2 at 1st week and next 250 mg/m2 weekly plus FOLFIRI biweekly was done. We defined 1 cycle as 8 weeks and studies were performed at this week. Results: Median follow-up period was 6. 2 (1. 1-13. 9) months. After 8 weeks, 50% patients had partial response and disease control rate was 57. 5%. Median time to progression was 3 months. EGFR expression and tumor response had no correlation (P=0. 07). Skin reaction and tumor response(median time to progression) had significant correlation (P=0. 022). cetuximab did not increase the toxicity associated with FOLFIRI except acneiform rash. Conclusions: Cetuximab combined with FOLFIRI chemotherapy was effective in metastatic colorectal cancer, who progressed after FOLFIRI regimen chemotherapy. P036 INDICATIONS FOR COLONIC J-POUCH RECONSTRUCTION AFTER ANTERIOR RESECTION FOR RECTAL CANCER: DETERMINING THE OPTIMUM LEVEL OF ANASTOMOSIS, Jin-ichi Hida MD, Takehito Yoshifuji MD, Fumiaki Sugiura MD, Masako Takemoto MD, Takashi Hattori MD, Kazuki Ueda MD, Eizaburou Ishimaru MD, Tadao Tokoro MD, Masayuki Yasutomi MD, Hitoshi Shiozaki MD, Kiyotaka Okuno MD, Department of Surgery, Kinki University School of Medicine, Osaka, Japan Purpose: Functional outcome after anterior resection for rectal cancer is improved by colonic J-pouch reconstruction compared with straight anastomosis. The indications for colonic J-pouch reconstruction have yet to be determined. Therefore, we attempted to determine the level at which J-pouch reconstruction provides an advantage over straight anastomosis. Methods: A total of 48 patients who underwent 5-cm colonic J-pouch reconstruction (J-pouch group) and 80 patients who underwent straight anastomosis (straight group) underwent functional assessment one year postoperatively. Results: The functional outcome in the J-pouch group was significantly better than that in the straight group when the distance of the anastomosis from the anal verge was less than 8cm. The difference was particularly obvious when the level of the anastomosis was below 4cm. However, functional outcome in the straight group when the anastomosis was between 9 and 12cm from the anal verge was also satisfactory and did not differ from that in the J-pouch group when the anastomosis was between 5 and 8cm from the anal verge. Conclusions: Colonic J-pouch reconstruction is indicated when the distance of anastomosis from the anal verge is less than 8cm, and it is essential when the distance is less than 4cm. P037 EXAMINATION OF NODAL METASTASES BY A CLEARING METHOD SUPPORTS PELVIC PLEXUS PRESERVATION IN RECTAL CANCER SURGERY, Jin-ichi Hida MD, Takehito Yoshifuji MD, Fumiaki Sugiura MD, Masako Takemoto MD, Takashi Hattori MD, Kazuki Ueda MD, Eizaburou Ishimaru MD, Tadao Tokoro MD, Masayuki Yasutomi MD, Hitoshi Shiozaki MD, Kiyotaka Okuno MD, Department of Surgery, Kinki University School of Medicine, Osaka, Japan Purpose: In rectal cancer surgery preservation of urinary and sexual function is attempted by means of operations preserving the autonomic nerves of the pelvic plexus. Emergence of residual cancer because of a more shallow plane of dissection is a problem of concern with these methods, so we examined indications for pelvic plexus preservation. Methods: We studied 198 patients with rectal carcinoma who underwent abdominopelvic lymphadenectomy. Lymph nodes along the superior hemorrhoidal artery and middle hemorrhoidal artery medial to the pelvic plexus were defined as perirectal nodes, and nodes along the middle hemorrhoidal artery lateral to the pelvic plexus and along the internal iliac artery represented lateral intermediate nodes. Node metastases were examined by the clearing method. Results: Metastasis to perirectal nodes occurred in 12. 5% in patients with pT1 tumors, 28. 9% of those with pT2 tomors, and 50. 0% of those with rectosigmoid junctional cancer. Metastasis to lateral intermediate nodes was absent in patients with pT1 or pT2 and was as low as 2. 5% in patients with rectosimoid junctional cancer. Conclusions: In patients with T1, T2, and rectosigmoid junctional cancer, perirectal node dissection is necessary, but chances of residual cancer should remain minimal when the pelvic plexus is preserved. 75 ABSTRACT BOOK Poster Papers P038 PSEUDO-MEIG’S SYNDROME CAUSED BY OVARIAN METASTASIS FROM COLORECTAL CANCER: REPORT OF 4 CASES AND REVIEW OF THE JAPANESE LITERATURE, Masatsugu Ishii MD, Keiichiro Ishibashi PhD, Masaru Yokoyama PhD, Kouki Kuwabara MD, Toru Ishiguro MD, Tomonori Ohsawa MD, Norimichi Okada PhD, Tatsuya Miyazaki PhD, Moriyuki Matsuki PhD, Hideyuki Ishida PhD, Department of Digestive Tract and General Surgery, Saitama medical Center, Saitama Medical University Pseudo-Meig’s syndrome is characterized by rapid improvement of ascites and hydrothorax, which is cured by removing ovarian or pelvic tumors, with the exception of ovarian fibroma. However, little is known about the characteristics of this syndrome when caused by ovarian metastases of colorectal cancer. We encountered four cases of pseudo-Meig’s syndrome caused by ovarian metastasis of colorectal cancer, three of which have been published elsewhere. Including our four cases, 17 cases were collected from the Japanese literature (11 from articles, and 5 from meeting abstracts, JMEDICINE: 1986-2007) and analyzed. Patient ages ranged from 32 to 75 years, and the sites of the primary lesions were cecum in one, the ascending colon in one, descending colon in one, sigmoid colon in ten, and rectum is three. Histological examination demonstrated well-differentiated adenocarcinoma in seven, moderately differentiated adenocarcinoma in six, and unknown in four. Hypothorax was found bilaterally in three cases, right-sided in seven, left-sided in four, and unknown in three. Ovarian metastasis was detected synchronously in ten and metachronously in seven. Bilateral ovaries were involved in six, right in five, and left in six. All patients underwent colectomy and oophorectomy. Three-year survival rate after oophorectomy was 53%. Our findings indicate that surgical treatment for pseudoMeig’s syndrome caused by ovarian metastasis from colorectal cancer can improve the prognosis. P039 CARCINOSARCOMA OF THE COLON: A CASE REPORT, Jung G Kang MD, Suh J Kim MD, Yoon J Choi* MD, Department of Surgery and *Pathology, National Health Insurance Corporation, Ilsan Hospital 1 Yonsei University Introduction: Carcinosarcoma is a rare tumor that contains malignant epithelial and mesenchymal element. It was usually detected in the head and neck, the respiratory tract and the female reproductive tract. Carcinosarcoma is a rare case in GI tract, especially in colon and has very poor prognosis despite massive treatment. Result: A 65 years old male patient admitted to our surgical department because of abdominal pain for 1 year. Preoperative evaluations revealed far advanced colon cancer involving the ascending colon and pneumoperitoneum with ascites in right subhepatic space and perisplenic space, suggesting panperitonitis on abdomen and pelvic cat scan and plain X-ray film. Emergency right hemicolectomy was carried out. At operation, the ascending colon showed a huge serosally protruding mass. On opening, an ulcerofungating and annular constrictive mass about 11x9cm was noted, which was 8cm apart from the ileocecal valve. On microscopicc examination, the tumor showed areas of poorly differentiated adenocarcinoma partly covered by normal mucosa, and areas of pleomorphic giant and short spindle cells favoring sarcomatous differentiation. Conclusion: A carcinosarcoma is a rare malignant tumor in colon, composed of mixed malignant epithelial and mesenchymal cells, and also has poor prognosis. Early diagnosis and aggressive managment of radical surgery with adjuvant chemotherapy and close follow - up should be considered. P040 QUALITY OF LIFE IN PATIENTS TREATED WITH ABDOMINOPERINEAL RESECTION OR ANTERIOR RESECTION FOR RECTAL CANCER, Jin-ichi Hida MD, Takehito Yoshifuji MD, Fumiaki Sugiura MD, Masako Takemoto MD, Takashi Hattori MD, Kazuki Ueda MD, Eizaburou Ishimaru MD, Tadao Tokoro MD, Masayuki Yasutomi MD, Hitoshi Shiozaki MD, Kiyotaka Okuno MD, Department of Surgery, Kinki University School of Medicine, Osaka, Japan Purpose: Patients with rectal cancer who undergo abdominoperineal resection (APR) are physically burdened by the presence of a permanent colostomy. We compared physical conditions of patients treated by APR with those of patients 76 ISUCRS XXII BIENNIAL CONGRESS treated by anterior resection (sphincter-saving operation) and found out whether the choice of operation technique had any influence on their social and psychologic conditions. Methods: Using a questionnaire, we compared the postoperative physical, social, and psychologic conditions of 40 patients who underwent APR with those of 116 patients who underwent anterior resection. Results: Physical conditions in the APR group were significantly worse than those in the anterior resection group. There were no significant differences in social conditions between the two groups, and social conditions were satisfactory in both groups. However, the will to live in the APR group was significantly less than that in the anterior resection group. Conclusions: Although most patients who undergo APR return to their normal level of social condition after surgery, their will to live is less because of physical discomforts, including bowel dysfunction, urinary dysfunction, and sexual dysfunction. The quality of life is influenced by multiple factors, one of which may be the presence of the colostomy. P041 EFFECT OF PREOPERATIVE VERSUS POSTOPERATIVE CHEMORADIOTHERAPY ON FUNCTIONAL OUTCOME AFTER SURGERY FOR RECTAL CANCER, Alexis Grucela MD, Roger Li BA, David B Chessin MD, Randolph M Steinhagen MD, Mount Sinai Medical Center Introduction: Until recently, the standard of care for stage 2 and 3 rectal cancer patients involved the administration of postoperative chemoradiotherapy. However, in recent clinical trials, preoperative chemoradiotherapy has been shown to result in equal long term survival with the potential for better functional results without an increase in perioperative complications. Therefore, we evaluated our experience with chemoradiotherapy and surgery for rectal cancer to evaluate functional results and postoperative complications. Methods: We queried the prospectively maintained surgical database to identify all patients with rectal cancer treated between 1999-2007. Only those patients whose surgery consisted of radical resection with curative intent and reestablishment of intestinal continuity were included. A comprehensive chart review of the included patients was performed to evaluate the nature and frequency of postsurgical complications. In addition, symptoms regarding bowel function were recorded and a novel Bowel Dysfunction Score (BDS) was calculated for each patient. Results: 43 consecutive patients meeting the inclusion criteria were identified. Data concerning the incidence of post-operative complications indicate that preoperative chemoradiotherapy results in fewer complications than does postoperative or no therapy. Preoperative patients had an average of 0. 89 postsurgical complications, postoperative patients had 1. 29, and patients with no therapy had 1. 2. Patients that received neoadjuvant chemoradiation were found to have a lower BDS than postoperative and no therapy patients. Conclusion: Preoperative chemoradiotherapy results in fewer postsurgical complications and leads to better bowel function than postoperative chemoradiotherapy or no therapy. Combined with equal long term survival, this adds additional evidence that neoadjuvant therapy should be considered the standard of care for the treatment of locally advanced rectal cancer. P042 DIETARY CHANGE AND THE INCREASE OF COLORECTAL CANCER IN KOREA AND JAPAN, Sun-Il Lee MD, Jung-Myun Kwak MD, Dong-Jin Choi MD, Sung-Soo Kim MD, Hwan-Soo Kim MD, Jun-Min Joe MD, Jin Kim MD, Byung-Wook Min MD, Jun-Won Um MD, Seon-Hahn Kim MD, Hong-Young Moon MD, Department of Surgery, Korea University College of Medicine Epidemiologic studies showed that colorectal cancer is related to the dietary environment especially to meat consumption. The change to westernized diet has been found in many Asian countries including Korea and Japan, and it is supposed that the dietary change would influence on the incidence of colorectal cancer in these countries. In this study, we investigated the change of meat and cereal consumptions and the change of colon and rectal cancer between two countries. The consumptions of meat and cereal in Japan (1950 to 2002) and Korea (1970 to 2003), and the colorectal cancer incidences in Japan (1975 to 1998) and Korea (1992 to 2002) were collected from the national published data which were studied nationwide in those two countries. The ABSTRACT BOOK Poster Papers age-adjusted incidences were compared with time differences. Meat consumption had been increased about 2. 5 times during 1970 to 1980 and colorectal cancer had increased more than 2. 5 times during 1992 to 2002 in Korea. We found that the changes in meat and cereal consumption as well as the increases in incidence of colon and rectal cancer were similar in those two countries with the 20 years of time difference. However, the increase of rectal cancer in Korea especially for women was higher than that of Japan, and further studies are required. The similarities and differences between Korea and Japan could be helpful to predict future colorectal cancer incidences for Korea and even for other Asian countries. with over-the-counter medications. They included hemorrhoidal creams and supposiories, laxatives, medication for colitis and intestinal amebiasis. In this group, patient delay mean average was 31 weeks. (range 2 wees to 3 years). Conclusions: This study showed that most patients presenting rectal cancer symptoms, erroneously credited them to common colorectal diseases. Self treatment resulted in a patient delay average of over 7 months. Delayed diagnosis of rectal cancer has remained a world wide constant for decades. The principal cause appears to be a lack of knowledge in the meaning of rectal cancer symptoms. Health education regarding rectal cancer, needs to be more emphasized in the general population. P043 EPIDEMIOLOGY OF COLON & RECTAL CANCER IN IRAQ, Z. Al-Bahraini MD, Adil H Al-Humadi MD, State University of New York at Buffalo and University of Baghdad, Iraq Purpose: This study evaluates the descriptive epidemiology and clinical aspects of colorectal cancer in the Iraqi population. Method: Records of patients diagnosed with colorectal cancer for a period of thirty years from 1965 to 1994 in Baghdad Medical City Teaching Hospital were reviewed. The material was analyzed retrospectively to study the epidemiological increase of cancer of the colon and rectum in the Iraqi population. Results: There were 511 patients diagnosed with colorectal cancer between 1965-1994. The male/female incidence was 1. 4/1 for colon cancer and 1. 1/1. 0 for rectal cancer. The highest incidence was seen at the median age of 50. A total of 21. 1 percent of patients were younger than 40 years of age. The population of Iraq in 1993 was 19 million composed of 15. 5 million Arabs and 2. 5 million Kurds with the incidence ratio of 6/1 for colon cancer and 5. 3/1 for rectal cancer. The most common symptom was change in bowel habits with obstructions for colon cancer (51%), rectal bleeding and change in bowel habits for rectal cancer (71. 5%). The rectum was the most common site 47% followed by the left colon and sigmoid colon 27% and the right colon at 26%. The predisposing factors related to adenomatous polyps 3%, familial polyps 5% and ulcerative colitis 3%. Pathological classification was Duke’s D lesion 56. 9%, Duke’s C leson 71. 3%, Duke’s B and Duke’s A 7%. Discussion: Comparatve studies in the Iraqi Cancer Registry during the 30 year period (65-94) showed an increased incidence of colorectal cancer from 25% to 50% and a decrease of gastic cancer from 78% to 50%. The incidence of colorectal cancer in Iraq is 2. 6% compared to 6-13% in the developed countries and 17-51. 1% in the industriaized nations. Conclusion: Iraq shares the epidemiological characters of developing countries in the Middle East. There is a shift towards the western-style of living that has probably lead to the increase of colon and rectal cancer in the Iraqi population. This increased incidence in colon and rectal cancer coincides with the decreased incidence in gastric cancer. The expected change in pattern of this disease in Iraq is probably related to the rapid change in dietary habits. P045 MALE URINARY DYSFUNCTION AFTER TOTAL MESORECTAL EXCISION, Hideyuki Ike MD, Yoshiro Fujii MD, Satoshi Hasegawa MD, Akio Ashida MD, Kenichi Matsuzu, Saiseikai Yokohama City Nanbu Hospital Purpose: To investigate urinary dysfunction after total mesorectal excision using electric cautery for rectal cancer. Patients and Methods: A total of 67 patients with lower rectal cancer who underwent total mesorectal excision between April 2005 and December 2007 at our department were included. Of these, 28 underwent low anterior resection, 10 Hartmannfs operation, and 29 abdomino-sacro-abdominal resection. Lateral lymphnode metastases were found in 7 patients. Pelvic autonomic nerves were completely preserved macroscopically during operation. Post-operative urinary status was evaluated. Results: Average age was 65 years, and number of male patients was 43 and female was 24. Average operation time was 3 hours and 51minutes, average blood loss was 353 ml and no patients received blood transfusion. There was no patients who needed clean intermittent catheterization, however 12 patients (17. 9%) received medicine for urinary dysfunction. Urinary dysfunction was found in only male patients. Incidence of urinary dysfunction according to the operation were 14. 3% in low anterior resection, 20% in Hartmannfs operation, and 20. 7% in abdomino-sacro-abdominal resection, respectively. Conclusion: Urinary dysfunction may occur in male patients with lower rectal cancer after total mesorectal excision using electric cautery. P044 PATIENTS DELAY IN THE DIAGNOSIS OF SYMPTOMATIC RECTAL CANCER, Fidel Ruiz Healy MD, Marta G Vargas Saldaña MD, Abel Jalife Montaño MD, Service of Coloproctology, Dept. of Surgery, Centro Hospitalario “Sanatorio Durango”, Mexico City, Mexico Introduction: Despite modern diagnostic tools and protocols, symptomatic patients with rectal cancer continue to delay diagnosis. As a result, patients are treated during advance stages of disease. Patients’ delay plays an important part in late diagnosis. Methods: A retrospective chart review of patients with rectal cancer was performed. Parameters include age, patient behavior during initial symptoms, diagnosis, treatment and time from onset of symptoms to a first visit to physician. Results: Forty patients (m/f 24/16) of a mean age of 62. 3 (range, 27-90) years were included. The most common symptom was rectal bleeding (72. 5%). Other symptoms included rectal pain (30%), constipation (7. 5%) and diarrhea (5%). Weight loss, rectal secretion and fecal impaction were also reported. Several patients presented multiple symptoms. Patients responded to symptoms in two ways. The first group with three patients (7. 5%) went to a physician. Patient delay mean average was 19 days. (range 4 - 35 days). The second group with 37 patients (92. 5%) diagnosed thmselves as hemorrhoidal diseases in 29, colitis in 3, intestinal amebiasis in 2, intestinal constipation in 2 and anal fissure in 1 patient. Treatment consisted www.isucrs.org/ P046 TOTAL PELVIC EXENTERATION FOR LOWER RECTAL CARCINOMA ASSOCIATED WITH VON MEYANBURG COMPLEX, Ryohei Watanabe MD, Y Saida MD, Y Nakamura MD, T Enomoto MD, K Takabayashi MD, A Otsuji MD, M Katagiri MD, S Nagao MD, S Kusachi MD, M Watanabe MD, J Nagao MD, Toho University Ohashi Medical Ctnter Third Department of Surgery Lower rectal carcinoma, as it has no serosa, often infiltrates neighboring organs including seminal vesicle, prostate gland, urinary bladder and vagina. In this study, we report a case of rectal carcinoma with a suspicion of direct invasion to the prostate gland and urinary bladder based on the preoperative imaging. A 75-year-old male with chief complaint of melena came to our clinic. Colonoscopy detected a circumferential type 2 lesion in the lower rectum. Abdominal CT and MRI described the swelling of regional lymph nodes (No. 251) and direct invasion to the prostate and bladder as well as diffuse cystic lesion in the liver. The cystic lesion was diagnosed as von Meyenburg complex, which was to be examined by intraoperative biopsy. Preoperative diagnosis was lower rectal cancer (Rb) with metastasis to other organs (Ai: bladder and prostate), N0, H0, P0, M0; Stage Vb. The patient was determined to undergo total pelvic exenteration with lateral lymph node dissection, ileal conduit and stoma creation on February 15 2007. Intraoperatively, white and yellow nodules diffusing on the surface of the liver was observed. The lateral segmental branch of the liver was biopsised, which was diagnosed von Meyenbur complex by intraoperative pathology. As H-factor is negative, we performed the operation mentioned above. Intraoperative pathology revealed inflammatory episode of the bladder and prostate that had been suspected to be direct invasion according to preoperative CT and MRI. In addition, in the prostate gland, small cancerous lesions of prostate were observed. Postoperative diagnosis was A, N0, H0, P0, M0; Stage U and the patient is alive with no recurrence for 12 months after the surgery. In this case, adhesion and induration of rectal peripheral tissue was remarkable so that en-bloc resection was applied to improve curability. As von Meyenburg complex was difficult to 77 ABSTRACT BOOK Poster Papers distinguish from diffuse hepatic metastasis preoperatively, not only preoperative MRI but also pathological diagnosis utilizing intraoperative liver biopsy would be feasible. P047 DISSEMINATED METASTASIS OF OVARIAN CARCINOMA IDENTIFIED THROUGH A SUBMUCOSAL RECTAL TUMOR, Ayako Otsuji MD, Y Saida MD, Y Nakamura MD, T Enomoto MD, K Takabayashi MD, R Watanabe MD, M Katagiri MD, S Nagao MD, S Kusachi MD, M Watanabe MD, J Nagao MD, Toho University Ohashi Medical Center, Third Department of Surgery In general, metastatic rate of ovarian cancer to large intestine is about 30%. As large intestine neighbors to ovaries, it is not rare. However, many cases of metastatic colorectal cancer especially in cases of disseminated matastasis, have macroscopically demonstrated nodular lesion on serosal surface and rubber and focal hypertrophy on mucosal surface, and few cases have demonstrated mucosal tumor and Type-1 or Type-2 tumor. In this study, we report a case of colonoscopically detected disseminated metastasis of ovarian carcinoma during the examination of submucosal carcinoma in lower rectum. A female patient in her late sixties was indicated positive occult blood reaction at medical check -up. In addition, a surface smooth subumucosal tumorous lesion was colonoscopically detected in the rectum. It was diagnosed as adenocarcinoma by biopsy. Under the suspection of rectal cancer, the patient was referred to our hospital. Endoscopic Ultrasonography (EUS) demonstrated a depressed image throughout all the layers. Abdominal Computed Tomography (CT) and pelvic Magnetic Resonance Imaging (MRI) described a 4x4x8cm tumor located in the right side of lower rectum, which compressed rectum. In right ovary, there was a solid tumor, 2cm in size. Tumor markers were high level; Carbonhydrate antigen (CA) 19-9: 53. 4; CA125: 788, though Carcinoembryonic Antigen (CEA) was in normal level. Based on these results, although there could be a possibility of rectal cancer and intrapelvic mass, we performed an open procedure under the preoperative diagnosis of metastatic ovarian carcinoma of rectum. Intraoperatively, a tumor 2cm in size was observed in right ovary. Intraoperative pathology determined it was ovarian carcinoma. In the omentum, many small nodular peritoneal disseminated lesions were observed. So, we performed total hysterectomy, birateral adnexectomy and omentectomy. Submucosal tumor in lower rectum was identified as an erastic hard surface smooth tumor 8cm in size, which located on the caudal to peritoneal reflection and on extrinsically right rectal posterior wall. We performed Hartmann’s operation with the inclusion of tumor. The patient’s prognosis has been well and she has undergone chemotherapy at gynecology department. P048 NEO-ADJUVANT THERAPY FOR CANCER OF THE LOWER RECTUM: LATE RESULTS: , jose a reis neto PhD, Jose A Reis jr MD, Odorino Kagohara MD, Joaquim Simoes Neto MD, Silvio A Ciquini, Sergio Banci, CRN, PUCCampinas Aims: Pre-operative radiotherapy as adjuvant treatment for cancer of the Lower Rectum, although recognized as effective on controlling the interval-free of rectal cancer, has not been utilized as frequently as expected. The objective of this trial is to analyze the results of radiotherapy as adjuvant treatment for Cancer of the Lower Rectum. Methodology: From 1978 to 2007, a total of 358 patients with rectal cancer were submitted to preoperative radiotherapy. Only patients with rectal adenocarcinoma situated in the lower rectum ( between the pectinate line and 10 cm above it) classi-fied as TNM stages II and III were included in this study. There was no gender, race and age distinction. Preoperative radiotherapy was performed according to the follow-ing scheme: 200 cGy / daily for 4 consecutive weeks up to a total of 4000 cGy, by means of a Linear Megavoltage Accelerator (25 MeV), in anterior and posterior pel-vic fields. All patients were operated on after conclusion of the irradiation according to tumor stage observed post-irradiation. According to the anatomopathological finding on surgical specimen, patients classified as TNM stages I received no further treat-ment; those considered as stages II or III after surgery, were submitted to adjuvant therapy (5FU and leucovorin - 8 cycles). Results: Of the 358 patients, 64, 5% were classified as TNM stage I at surgery. Statis-tical analysis of the whole group showed that pre-operative 78 ISUCRS XXII BIENNIAL CONGRESS RDT does decrease the incidence of local recurrence: 3, 48 %. Moreover, the frequency of undifferentiated cells diminished after irradiation. Pre-operative RDT reduces tumoral volume and wall invasion, as well as the mortality rate due to local recurrence (2, 43%) and alters long-term survival rate (80, 17%). Preoperative radiotherapy is really effective in reducing the number of undifferentiated cells and in diminishing the carcinomatous infiltration of the rectal wall. Consequently local recurrence rate is decreased and mortality due to local recurrence declines. P049 GASTOROINTESTINAL STROMAL TUMOR(GIST) IN THE COLON AND THE RECTUM CLINICAL CHARACTERISTICS AND THERAPY IN SIX CASES, Toshihiro Fujita MD, Michio Itabashi MD, Shingo Kameoka MD, Department of Surgery, Tokyo Women’s University School of Medicine Gastrointestinal stromal tumors (GIST) in the colon and rectum are a relatively rare. We experience 6cases of GIST in the colon and rectum between 1993 and 2008. There are four men and two women with a median age of 53 years (range: 43-81)at the diagnosisi. 4cases in the rectum, one in the sigmoid colon, one in the retroperitoneum. The most frequent symptoms were abdominal pain. The median tumor size was 6 centimeters(range: 3cm-20cm). Two patients underwent abdominoperineal resection(APR), 1 underwent transanal endoscopic microsurgery(TEM)1 had a resection of sigmoid colon. 4 patient received imatinib treatment before or after operation. 2 cases having local recurrence or distant metastasis, 48 months and 92 months after surgery, respectively. The former died 63 months after the operation. one died of tumor rupture 9 mounths after diagnosis. one died of other disease 1month after surgery. On the occasion of these six observations, we will investigated the clinicopathologic characteristics of them. Colorectal Emergencies P050 SELF-EXPANDABLE METALIC STENT COLON AND RECTUM, Y Saida MD, Y Nakamura MD, T Enomoto MD, K Takabayashi MD, M Katagiri MD, S Nagao MD, S Kusachi, M Watanabe MD, Y Sumiyama MD, J Nagao MD, Toho University Ohashi Medical Center Purpose: In the treatment of obstructive colorectal cancer, we first should relieve ileus in the same time that we pursue improvement of operative curability and safety when we could perform the curative surgery. To avoid emergency operation and stoma creation, and improvement of patients’ Egeneral condition, we use self-Expandable Metallic Stent (EMS) placement. We report the result of this therapy in our institution. Methods: Since 1993, we have proactively performed EMS placement for the treatment of obstructive colorectal cancer associated introducing a guide wire under radiographic guidance and utilizing colonoscopy. Results: A total of 116 patients underwent EMS placement for colorectal stenosis during October 1993 and January 2008. Those included 84 bridge to surgery cases, 28 palliative purpose cases for unresectable malignant diseases and 5 anastomotic stricture cases. The stent insertion was able to be successfully performed in 108 cases (successful rate: 93%). Complications at the time of insertion were; 3 perforation cases in sigmoid colon (3%) and 2 migration in descending colon and rectum (2%). The surgery enabled 98% of total case to EMS insertion of bridge to surgery. The duration of preoperative EMS placement was 3-27 days (mean: 6. 7 days). Postoperative complications included 1 wound infection, 1 ileus, 1 abdominal abscess and 1 leakage. These results are considered to be relatively favorable. The rate of stoma creation after bridge to surgery insertion was 12%, which is lower than the rate of 70% from the cases that EMS could not be placed. Circumferentially obstructive colorectal cancer often gives us difficult preoperative treatment, risk of contaminated operation and the need for secondary operation. But EMS enables us to obtain wider lumen to decrease the pressure of proximal intestine. For palliative purpose, all patients ileus were released quickly. But we have 10% of re-obstruction required re-stent. Conclusions: To treat colonic obstruction, EMS placement therapy gives us significant meanings in the improvement of surgical results due to preoperative insertion, or the avoidance of excess invasion and the improvement of patients’ EQOL in palliative treatment. Therefore, we believe that this procedure should be more and more employed and improved. ABSTRACT BOOK Poster Papers P051 IS ONE-STAGE PROCEDURE IN THE EMERGENCY LEFT COLECTOMY SAFE?, J. O Kim MD, S. K Kee MD, O. K Kwon MD, S. Y Nam MD, Department of Surgery, Kumi Cha Hospital, Pochon Cha University Background: It is well known that the emergent left colon surgery increases morbidity and mortality. The paradigms in the surgical management of the emergent left colon surgery like obstruction and perforation are changing. The aim of this retrospective study is to define whether one stage colectomy without intraoperative colon preparation and/or protecting stoma is acceptable in low risk patients. Methods: From March 2006 to January 2008, the cases of a total 14 patients(5 men and 9 women) with a mean age of 66(18-91 years old) underwent the emergency left colectomy. 6 cancer obstructions(2 descending colons, 3 sigmoid colons, and 1 rectum), 4 cancer perforations(1 sigmoid and 3 recta), 2 sigmoid diverticualr perforations, and 2 sigmoid stercoral perforations were included. Results: 6 cancer obstruction patients and 5 perforation(3 cancers and 2 diverticulars) patients with localized peritonitis received resection and anastomosis(2 hemicolectomies, 5 anterior resections, 2 low anterior resections, and 2 segmental sigmoid resections) without colonic irrigation and/or protecting stoma. These patients had good general conditions and stable vital signs before surgery. Malecot catheter was introduced per anus for decompression in case of 3 sigmoid colon cancer and 1 rectal cancer obstructions. 1 total colectomy and ileorectal anastomosis(stercoral perforation) and 2 Hartmann¡¯s procedures(1 rectal cancer and 1 stercoral perforation) were performed. These 3 patients were already septic and had massive fecal contamination with generalized peritonitis and died postoperative day 1, 7, 16 respectively. Of 11 resection and anastomosis, there was no anastomotic leakage and mortality. Only one patient had partial intestinal obstruction who improved with conservative treatment. They started sip¡¯s of water on mean postoperative day 4. 5(3-7th day). Conclusion: One stage resection and anastomosis without colonic lavage and/ or protecting stoma in emergency left colectomy can be safely performed in patients with low anesthetic risks(ASA 1 and 2). But our series are small. Large prospective trials are needed to confirm these results. P052 COLITIS ISCHEMIC, Giuseppe Accarpio s Accarpio MD, Puglisi R. s Puglisi MD, Zaffarano R.

Controversial Subjects P053 EFFECT OF MOSAPRIDE CITRATE ON POSTOPERATIVE ILEUS AFTER SURGICAL RESECTION OF COLON CANCER, Akira Tsunoda PhD, Yuko Tsunoda PhD, Makoto Watanabe PhD, Nobuaki Matsui MD, Kohji Takenaka MD, Kazuhiro Narita PhD, Mitsuo Kusano PhD, Department of General and Gastroenterological Surgery, Showa University School of Medicine Purpose: Mosapride citrate (mosapride) is a serotonin 5-hydroxytryptamine 4 receptor agonist that is known to promote gastric emptying and large intestinel motility. We assessed the effect of mosapride on postoperative ileus (POI) following colon surgery. Methods: The subjects were colon cancer patients who underwent hand-assisted laparoscopic colectomy (HALC). The subjects were randomly assigned to a mosapride group (M group) or control group (C group). The M group was given mosapride with 50 ml of water three times a day starting on postoperative day (POD) 1. The C group was given only 50 ml of water on the same www.isucrs.org/ schedule. Patients were allowed to resume oral feeding following on the evening of POD 2. Postoperative gastric emptying was evaluated by the [13C]-acetate breath test. Results: The maximal gastric emptying rate as determined by the breath test 48 hours postoperatively was significantly earlier in the M group than in the C group. Resolution of bowel movement was significantly earlier in the M group than in the C group. Conclusions: Gastric emptying was improved by mosapride. The results suggested that the period of POI following HALC can be shortened by treatment with mosapride. P054 AMENDMENT OF ROME III F. FUNCTIONAL ANORECTAL DISORDERS, Masahiro Takano BA, Coloproctology Center, Takano Hospital Purpose: Newly published Rome III is improved in F. Functional Anorectal Disorders regarding the adoption of physical findings and the data of laboratory examinations. However, it still has the following drawbacks in 1. F2a1. Levator ani syndrome and 2. F2b. Proctalgia fugax and the amendments are necessary in the following revision. Subjects: 1. One hundred and ten cases of chronic anorectal pain were examined to define tender areas in their pelvis with digital examination. 2. Sixty-eight cases of proctalgia fugax were examined to find tender areas when they were free of pain attack. Result: 1-1. Naming of levator ani syndrome is delusive because the same name is used to express the pathological status of hypertrophy of the levator resulting in difficult evacuation as stated by Wassermann. 1-2. According to the diagnostic criteria of F2a1. Levator ani syndrome, tenderness is cased by posterior traction on the puborectalis. However, when I tried the procedure, cases with tenderness limited on the puborectalis were only 4 among the 110 cases (4%), cases with tenderness overlapping the muscle and pudendal nerve were 28 (24%) and cases with tenderness only on the latter were 84 (78%). The above-mentioned data show the tender areas are mainly not the levator but the pudendal nerve. 2. In Rome III, the pathology of F2b. Proctalgia fugax is not clarified but only estimated to be abnormal contraction of the smooth muscle, induced by stress or anxiety for which no effective and curative measures are found. However, when I examined and palpated the pelvis, 55 of the 68 cases complained of tenderness on the pudendal nerve. The evidences show the origin of the pain is the pudendal nerve and the pathological entity is pudendal neuropathy. Conclusion: Although new Rome III F item is better than that of Rome II in adoption of findings as the criteria, it is not complete in the pursuit of the pathogeneses. For example, pudendal neuropathy exists on the bases of F2a and F2b. P055 CROSS-MATCHING IN COLORECTAL SURGERY: A VALUABLE RESOURCE WASTED, J D Terrace MD, D N Anderson MD, Academic Unit of Coloproctology, University of Edinburgh Introduction: Guidelines for blood cross-matching in surgery vary widely between centres. Increasing pressure on transfusion service resources mean that a consensus approach to blood ordering is overdue. This study aimed to examine the patterns of red cell cross-matching and transfusion in colorectal surgery, with the hypothesis that excessive cross-matching remains prevalent. Methods: Regional transfusion service database and case note review of consecutive colorectal operations (one consultant) in a single centre over a 30 month period. Benign and malignant disease was identified histologically from resected specimens. Results: 277 cases were identified. 101 patients had benign disease (51% IBD, 27% diverticular disease). 176 patients had colorectal malignancy (52% left-sided and 32% right-sided colectomy). There were no significant differences in transfusion or cross-matching levels for benign versus malignant or left versus right sided lesions. However, significant differences were observed for ulcerative colitis compared with other benign or malignant disease (mean 2. 4 versus 1. 1 transfused units per operation; mean 5. 2 versus 3. 6 cross-matched units per operation). Similarly, significant variation was apparent when comparing emergency and elective surgery (mean 2 versus 0. 9 u. p. o transfused; mean 4. 7 versus 3. 3 u. p. o cross-matched). Of the total 1088 units cross-matched, only 359 were transfused. Conclusions: Although emergency and UC surgery had twice the transfusion requirement of other procedures, excessive crossmatching was prevalent in all operations, with serious financial and resource implications. 79 ABSTRACT BOOK Poster Papers Fecal Incontinence Eur Surg Res 1993; 25: 399-405. P056 CLINICAL AND PHYSIOLOGICAL EVALUATION OF ANAL SPHINCTER RADIOFREQUENCY REMODELING - 12 MONTHS EXPERIENCE, Roman M Herman PhD, Piotr Walega PhD, Michal Nowakowski PhD, Katarzyna Smeder MD, Jerzy Salowka MD, Dorota Zelazny MD, Jakub Kenig MD, 3rd Department of General Surgery Jagiellonian University Collegium Medicum Background: The main doubt reducing enthusiasm for the radiofrequency remodeling technique (secca) was based on lack of physiological studies, which may explain the possible pathomechanism of improvement of symptoms. Aim: The aim of this study was clinical physiological evaluation of the anorectal function prior and during 12 months follow-up after the secca procedure. Material: 16 fecal incontinence (FI) patients (4 male and 12 female, mean age 59 ranged 41-78 years) have been enrolled into the study. The standard technique and secca device was used (Curon Medical, Freemont, CA USA). The following parameters were evaluated at baseline, 3, 6 and 12 months after the procedure: continence (CCF-FI, FI-SI scores), improvement (FI-QoL, patient diary, VAS), electromyography (EAS-superficial, IAS-needle), rectal electro- and thermosensitivity, barostat, anal manometry, morphology (endoanal ultrasound). Results: Comparing to baseline, 1, 3, 6 and 12 months average results were as follows: CCF-FI 12, 1 - 10, 4 - 9, 1 - 9, 3 - 6, 8; FI-SI 36, 9 - 38, 6 - 34, 9 - 35, 2 - 30, 8; compliance 5, 6 - 5, 6 - 4, 0 - 4, 2 - 4, 0; manometry BAP 30, 6 - 34, 23 - 39, 3 - 42 - 43, SAP 73, 15 - 75, 53 - 86, 07 - 96, 69 - 96, 3; electrosensation 23 - 53 - 52 - 41 - 37, thermosensation 0, 7 - 0, 28 0, 3 - 0, 4 - 0, 4, respectively. In FI-Qol scale significant improvement in 4 of 4 measures was observed, as well as IAS and EAS electromyography improvement. Conclusions: Secca remodeling is safe and seems to be effective method of FI treatment. It reduces the frequency and severity of FI symptoms, and improves patient’s quality of life. This effect seems to be related to restored anorectal sensitivity and recto-anal coordination, however effect on IAS morphology and function is also detectable. P058 ARTIFICIAL SOFT ANAL BAND - RESULTS OF METHOD APPLICATION IN POLAND, Roman M Herman PhD, Piotr walega PhD, Michal Nowakowski PhD, Katarzyna Smeder MD, Jerzy Salowka MD, Dorota Zelazny MD, Jakub Kenig MD, 3rd Department of General Surgery Jagiellonian University Collegium Medicum Background: For patients with severe, irreparable fecal incontinence, the surgical options are limited. The last-step procedure is Artificial Bowel Sphincter (ABS) implantation. Aim: The aim of this study is to present preliminary results of artificial bowel sphincter (A. M. I. ) implantation in Poland, around the natural anus and around the ostomy. Material: Eight patients (3 female and 5 male, age 27-55) with IVth grade fecal incontinence were qualified to the procedure and two patients with an ostomy: (1 female after the Miles procedure and 1 male after perinaeal injury). Between January 2006 and December 2007 in 8 patients the anal band was implanted around the natural anus. In two patients the band was implanted around the ostomy in the abdominal wall. Soft Anal Band (SAB) is a modified bowel sphincter physiological shape and with modified connections with pump. Results: No intraoperative complications were observed. In two patients SAB was removed due to the local infection after 15 weeks and 6 weeks, respectively, one with subsequent reimplantatation. In two patients the system needed to be recalibrated after 4 and 5 months. In one patient, 4 weeks after the surgery, due to perineal suture line dehiscence, additional stitches were placed with satisfaction outcome. Comparing to baseline, 3 and 6 months average results were as follows: CCF-FI 12 - 9, 2 - 7, 8; FI-SI 47, 33 - 34, 8 - 32, 8; manometry BAP(deflatedSAB) 31, 4 53 - 52; SAP(inflatedSAB) 57, 3 - 86 - 94. In FI-Qol scale significant improvement in 4 of 4 measures was observed. Conclusions: Artificial anal band implantation is the effective procedure for majority of patients with IVth stage sphincters injury and improves QoL. Anal band implanted around the ostomy allows controlling the time and place for intestine emptying. P057 NEOSTIGMINE INJECTION FOR THE TREATMENT OF PARTIAL FECAL INCONTINENCE, Ismail A. Shafik MD, Cairo University Background/Aim: The treatment of partial fecal incontinence (PFI) after internal anal (IA) sphincterotomy for chronic anal fissure (CAF) is problematic. Prostigmine (PROS) (neostigmine methyl sulphate) inhibits acetylcholine destruction and thus prolongs the physiological actions of AC, and facilitates impulse transmission across the myoneural junction. Therapeutically, PROS stimulates muscle contraction. The current study investigated the hypothesis that PROS effects cure of PFI following IA sphincterotomy for CAF. Methods: Forty-eight patients with FI following IA sphincterotomy for CAF received PROS injection into internal anal sphincter (IAS) once/2 weeks for 12 weeks. Eighteen patients with PFI after IA sphincterotomy for CAF acted as controls. Subjects were administered IAS injections at 3 and 9 o’clock position of 0. 25 mg prostigmine in almond oil (patients) or placebo (almond oil) (controls). Anorectal manometry was performed before and after injection. Results: PROS effected significant elevation of both maximal resting and maximal squeezing pressures and of IAS EMG activity in all PROS-injected patients up to the 18th post-injection week with no effect in controls. All PROS-injected patients became continent. At the 24th week, patients were divided into 3 scores: score 1 (complete continence) comprised 39 patients. Score 2 included 9 patients who were incontinent to flatus; they were reinjected and are now continent in score 1. No patient had score 3 (incontinent to fluid stools and flatus). Conclusion: Prostigmine injection into IAS significantly increased maximal resting and maximal squeezing pressures as well as IAS EMG and effected fecal control in patients with PFI. References: 1.

Academic Surgical Unit, University of Hull, Cottingham, UK Introduction: Sacral nerve stimulation has revolutioned the treatment of various pelvic disorders. The remit of its use has been increasing. An ileo-pouch anal anastomosis (IPAA) has become the gold standard procedure for ulcerative colitis and familial adenomatous polyposis. However, the operation may adversely impact the patient’s continence and quality of life. Studies have shown deterioration of continence and soiling. Treatment of Ileoanal Pouch incontinence can be difficult. The reports of the use of SNS in the treatment of Ileo-anal pouch incontinence are limited. We reviewed our experience in an isolated individual case in order to determine whether it is a worthwhile procedure. Methods: We aim to describe an isolated case of pouch incontinence who had a successful outcome with SNS. A prospectively maintained SNS database, was used for gathering the data. Results: Case report: A 53 year old male, was referred from a tertiary unit to consider SNS for pouch incontinence. He had undergone Subtotal Colectomy in 2001 and Ileo-anal pouch reconstruction in 2002. He was troubled with increased frequency of bowel movements from his Ileo-Anal Pouch and also Faecal Incontinence associated with Urgency, Frequency and Leakage. All these were affecting his quality of life significantly. Having failed the conservative treatments and collagen Injections, he was referred for considering SNS. Having undergone assessment for SNS, he had a temporary SNS on the left S2 nerve root. Bowel diaries showed good response with reduction in frequency of bowel movements from 9-10 times/ day to 2-3 times/day and on 3 days no leakage of stool. Patient described improved quality of life. Patient is awaiting a permanent SNS. Conclusions: Although results might be far less predictable since there is no benefit from parasympathetic neuromodulation (subtotal Colectomy), there may be a direct contact effect on the pouch. We conclude that SNS for pouch incontinence with our limited experience offers a satisfactory outcome, when other treatments have failed. However, we would like to see the long term outcomes. ABSTRACT BOOK Poster Papers P060 ROLE OF SACRAL NERVE STIMULATION FOR INCONTINENCE AFTER RECTAL PROLAPSE REPAIR, Joan Robert-Yap MD, Guillaume Zufferey MD, Karel Skala MD, Bruno Roche MD, Unit of Proctology, University Hospital of Geneva Introduction: Fecal Incontinence is the most common symptom of a full thickness rectal prolapse. One year after surgery, 20% of patients may continue to have symptoms of incontinence. Management of persistent symptoms of incontinence is difficult consisting of conservative therapy and/or surgery. One of these new treatments is sacral nerve stimulation (SNS), which stimulation of the sacral nerve by an electronic pulse generator, similar to a cardiac pacemaker. This results in a sensory and motor effect on the pelvic floor and its organs, which can improve bowel function in incontinence and/or constipation. Materials and Method: From January 2003 to December 2007. 9 female patients median age 62 years, range 42 - 86 years have been tested. Patients had incontinence symptoms despite rectal prolapse repair. Inclusion Criteria: Fecal incontinence occurring 7 days or more in a 21 day period, intact external anal sphincter +/- surgical repair, failed medical therapy, failed biofeedback/physiotherapy and, minimum 1 year after procedure. We reviewed all 9 SNS test operations performed in post rectal prolapse repair patients in the University of Geneva Hospital, Unit of Proctology. Of these 9 patients, 4 had Wells rectopexy procedures, 5 had Marti-Zaccharin procedures ( Rectopexy + total perineal repair). Additional previous procedures included 1 sphincteroplasty and 1 sigmoidectomy. 7 on 9 patients tested with incontinence had a positive Result: 78% success rate. Wexner incontinence score decreased from 14 in pre-implantation to 5 in post-implantaion. Conclusion: SNS is a minimally invasive procedure. It shows 78% success rate in 9 cases of incontinence in failed rectal prolapse repair. SNS has the advantage of testing to assess efficacy. It is a good treatment option to offer patients who have ongoing symptoms after rectal prolapse surgery. FUNCTIONAL DISEASE P061 ROLE OF SACRAL NERVE STIMULATION (SNS) IN VULVODYNIA, N Srinivasaiah MD, P Waudby RN, B Culbert, G S Duthie MD, 1. Academic Surgical Unit, University of Hull, Cottingham, UK. 2. Department of Anaesthetics, Castle Hill Hospital, Cottingham, UK Introduction: Vulvodynia is difficult to treat seriously affecting QOL. There are no reports of SNS in vulvodynia. We have reviewed our experience in two cases to determine whether it is a worthwhile procedure. Methods: Patients were identified from our prospectively maintained SNS database and the notes reviewed. Results: Case 1: A 62yr female cook was diagnosed to have vulvodynia when she was aged 20. Symptoms affected her QOL significantly. She experienced high intensity spasms lasting for 1-2 mts with worsening pain. With insignificant past medical history, aetiology has not been ascertained. Having failed analgesics, antiepileptics, antidepressants, phenytoin infusions and caudal blocks (Short lived), she was referred by the pain team for SNS. Following assessment for SNS, She had a temporary SNS on the left S2 root. Spasms were less severe lasting only 3040 seconds. On a PACS / BPI assessment there was 70% relief at the end of two weeks. Patient described improved QOL and is extremely happy with the outcome. The temporary wires were removed and the patient is awaiting permanent implant. Case 2: A 43 yr female dress designer was diagnosed vulvodynia associated with left buttock and perineal pain. With insignificant past medical history, aetiology has not been ascertained. Having failed analgesics, gabapentin and caudal blocks, she was referred by the pain team for considering SNS. Following assessment for SNS, She had 3 temporary SNS procedures done. The first one was a temporary SNS placed on right S3 nerve root. Not entirely satisfied with the marginal improvement she had, a second temporary SNS was done on the left involving S3. Following the failure of second SNS, unsatisfactory assessment on the right S3 led to a repeat right S3 test, which was successful. PACS / BPI assessment showed a reduction in pain of 60% after day 1 and 80% improvement at the end of 1st and 2nd week. Patient is extremely happy with the outcome and is awaiting for a permanent implant. Conclusions: SNS for vulvodynia with our limited experience offers a satisfactory outcome, when other treatments have failed. www.isucrs.org/ P062 LAPAROSCOPIC RESTORATIVE PROCTOCOLECTOMY AND ILEAL POUCH ANAL ANASTOMOSIS; HAVE WE PROGRESSED?, A Belizon MD, S Shawki MD, E Weiss MD, J Nogueras MD, D Sands MD, S Wexner MD, Cleveland Clinic Florida Restorative proctocolectomy and Ileal pouch anal anastomosis (IPAA) is the procedure of choice for patients with umcerative colitis. Laparoscopy has been applied to this procedure. This study set out to report our short-term results with laparoscopic restorative proctocolectomy and IPAA and compare it with a matched group of patients undergoing open surgery. Methods: All patients who underwent laparoscopic restorative proctocolectomy and IPAA were retrospectively reviewed using our prospectively maintained database. Charts were reviewed for demographics, operative time, blood loss, length of hospitalization, morbidity, and mortality. A group of 60 patients who underwent open restorative proctocolectomy and IPAA and were selected for comparison to the laparoscopic group. The patients were well matched for BMI, ASA, diagnosis, and age. Results: All 61 patients underwent laparoscopic restorative proctocolectomy and IPAA between 1991 and 2007. Including 5 patients in whom an operation was performed hand assisted. There were 4 conversions to laparotomy and fecal diversion was employed in all cases. The operative time in the matched group of 60 patients was significantly shorter than in the laparoscopic group (208 minutes vs. 276 minutes, P<0. 05). However the major morbidity rate was similar (7. 2% vs. 6. 2%) and the length of hospitalization was significantly longer (7. 6 vs. 5. 9; P<0. 05). There were no mortalities in either group. Conclusion: Laparoscopic IPAA may decrease the length of hospitalization and without increasing the morbidity. As technology improves and laparoscopic skills are refined this procedure may prove to be the treatment of choice for select patients. Further study is needed to evaluate the laparoscopic approach in a prospective randomized fashion. P063 ROLE OF SACRAL NERVE STIMULATION FOR CONSTIPATION AFTER RECTAL PROLAPSE REPAIR J. ROBERT-YAP, Guillaume Zufferey MD, Karel Skala MD, Bruno Roche MD, Unit of Proctology, University Hospital of Geneva Introduction: Constipation is a common symptom after abdominal surgery for of a full thickness rectal prolapse. Management of persistent symptoms of constipation is difficult and consists of conservative therapy and/or eventual surgery. One of these new treatments is sacral nerve stimulation (SNS). It involves stimulation of the sacral nerve by an electronic pulse generator, similar to a cardiac pacemaker. It is a minimally invasive procedure which is performed in 2 stages. It results in a sensory and motor effect in the pelvic floor and its organs and has been shown to regulate bowel function in incontinence and/or constipation. Materials and Method: From January 2003 to December 2007, 5 female patients median age 67 years, range 53 - 86 years had been tested. Patients had constipation symptoms despite rectal prolapse repair. We reviewed all 5 SNS test operations performed in post rectal prolapse repair patients in the University of Geneva Hospital, Unit of Proctology. Of these 5 patients, 3 had Wells rectopexy and 2 had Marti-Zaccharin procedures ( Rectopexy + total perineal repair). Additional previous procedures included 1 sigmoidectomy and 2 vaginal suspensions by promontofixation. Results: 4 on 5 patients tested with constipation had positive results: an 80% success rate. The Wexner constipation score decreased from 18 in pre-implantation to 10 in definitive implantation. There were no complications. Conclusion: SNS is a minimally invasive procedure. Our results show an 80% success rate using SNS in 5 cases of constipation after rectal prolapse repair with no complications. SNS has the advantage of a test phase to assess efficacy. It is a good treatment option to offer patients who have ongoing symptoms after rectal prolapse surgery. Infections P064 WITHDRAWN P065 COLONOSCOPIC DIAGNOSIS AND TREATMENT OF PERIAPPENDICULAR ABSCESS, Mette Christoffersen MS, Orhan Bulut MD, Per Jess DO, Gastroenterology Surgical Department, Hilleroed Hospital, Helsevej2, 3400 Hilleroed, Denmark 81 ABSTRACT BOOK Poster Papers Appendicitis is one of the most common diseases of the abdomen, and the diagnosis often can be difficult to make in atypical presentation. Periappendicular abscess, as a common complication to appendicitis, (2-6%) often requires long hospitalization. Colonoscopic diagnosis and treatment of asymptomatic acute appendicitis and periappendicular abscess are exceedingly rare. We present an atypical case of periappendicular/pericecal abscess that was drained during colonoscopy. Case Report: The patient was an 80-year-old woman without obvious symptoms of appendicitis admitted for colonoscopic polyp control. Physical examination was non-remarkable, except for slight tenderness at palpation in the lower abdomen. Laboratory tests at admission showed a marginally high white blood cell count of 10, 600/mm3 and a normal C-reactive protein level. Colonoscopy revealed a smooth- surfaced, ill-demarcated and sessile protrusion in the coecum. We attempted to obtain biopsies with regular instruments without success. Afterwards we managed to perforate the mass with the tip of a snare and a whitish fluid began to drain into the colon. The perforation was then dilated and a catheter was inserted to aspire pus for bacteriological examination, which later yielded E. coli and Bacteriodes fragilis. Multiple biopsies were obtained for histological examination as well. These showed normal colonic mucosa without malignancies or inflammation. After drainage the mass obviously disappeared. An acute abdominal ultrasound and CT scan was performed hereafter. Here the appendix was not visible and there was no free fluid or abscess formation. It showed a hypoeccoic oblong process, approx. 3, 5 cm. in the right fossa and inflammatory reaction around coecum. The patient was hospitalized for 5 days for observation and and discharged without symptoms and with normal laboratory tests. Three months later a new ultrasonographic examination showed a thickened oblong process in relation to coecum, most likely the rest of the previous abscess cavity. One-year follow up there was no sign of recurrence. Conclusion: Colonoscopic drainage, especially in combination with endosonographic examination seems to be a good option in the management of periappendicular or pericecal abscess in the elderly with surgical risk. P066 FEMORAL VENOUS CATHETER IS A MAJOR RISK FACTOR FOR CENTRAL VENOUS CATHETER RELATED BLOODSTREAM INFECTION IN COLORECTAL SURGERY. , Mitsuru Ishizuka MD, Hitoshi Nagata MD, Kazutoshi Takagi MD, Keiichi Kubota MD, Department of Gastroenterological Surgery, Dokkyo Medical University Background: Central venous catheter related bloodstream infection (CVC-RBSI) is a major complication that is associated with CVCs. However, there are few studies on the risk factors for CVC-RBSI in the patients who underwent colorectal surgery (CRS). Purpose: To disclose the risk factors for CVC-RBSI in CRS. Methods: CVC-RBSI was evaluated from the database of patients who underwent CRS retrospectively. Catheters were removed whenever fever (>380C) occurred or if symptoms of infection were present, such as skin redness and pus discharge at the insertion point, and then blood culture and culture of the catheter tip were done to diagnose any CVC-RBSI. Either blood culture positivity or catheter culture positivity were defined as CVC-RBSI. Results: Three hundred-fifty patients received 423 CVCs for a total of 7760 catheter-days. Thirty-nine cases were diagnosed as CVC-RBSI (5. 03, per 1000 catheter-days). There were no significant differences in the backgrounds between the cases with or without CVC-RBSI, except for the period of catheter insertion (24. 6 } 7. 0 vs17. 7 } 0. 6, P = 0. 0151). However, univariate analysis using the factors such as sex, age, troubles of insertion, length of inserted catheter, period of catheter insertion, performance of chemotherapy, performance of total parenteral nutrition (TPN), insults of operation and type of catheter revealed that femoral venous catheter (FVC) was an independent risk factor for CVC-RBSI (odds ratio, 4. 706; 95% C. I. , 1. 008-1. 062; P = 0. 0156). Conclusions: FVC is a major risk factor for CVC-RBSI in CRS. Inflammatory Bowel Disease P067 INFLIXIMAB IN THE TREATMENT OF PERIANAL CROHN DISEASE. , Roman M Herman PhD, Tomasz Cegielny MD, Jakub Kenig MD, Marcin Nowak PhD, Piotr Walega PhD, Jacek Sobocki PhD, IIIrd Department of General Surgery, Jagiellonian University Collegium Medicum 82 ISUCRS XXII BIENNIAL CONGRESS Introduction: Perianal fistulas are most frequent complication of Crohn’s disease. Conservative therapy and surgical procedures showed little success in the treatment of perianal fistulas. Infliximab, monoclonal anti-TNFalfa IgG’s has become more available method in therapy of complicated Crohn disease. Aim: Present the preliminary report of the perianal fistulas treatment with infliximab. Methods: 48 patients with Crohn’s have been treated in the period of last five years. 16 patients had perianal Crohn disease with draining simple or complex perianal fistulas. 9 patients (4 females and 5 males, at the age of 16-45) have been enrolled to IFX treatment. 7 patients underwent surgical procedures before or during IFX therapy. Endorectal ultrasound examination (ERUS) with the use of H2O2 have been used as diagnostic procedure. Results: Every patient involved in the study showed clinical response to therapy with IFX. Acute phase reactants (CRP) were normalized, as well as Crohn Disease Activity Index. CDAI reduced by 109 (+/-16, 4) points. More than 50% of fistulas tract closed spontaneously in 8 patients (88%). Non-cuting setons were taken off by 5-8th week of therapy. In 5 of the patients there was no fistula visualized in ERUS in 10th week. 7 patients were qualified for further maintenance therapy with IFX. Conclusions: The use of IFX is indicated in patients showing no response to standard therapeutic procedures. The use of IFX should be used as the bridge to immunosuppressant therapy. The results of clinical experience will be presented in future as the study on the use of IFX in patients with Crohn’s continues. P068 ENDORECTAL ULTRASOUND IMAGING IN EVALUATION OF CROHN’S PERIANAL FISTULAS. , Roman M Herman PhD, Marcin Nowak PhD, Tomasz Cegielny MD, Jakub Kenig MD, Piotr Walega PhD, IIIrd Department of General Surgery, Jagiellonian University Collegium Medicum Introduction: The three-dimensional ultrasound imaging enables evaluate the topography of the fistula. Endorectal ultrasound imaging is very useful in patients selection to both: surgical procedures and biological therapy with infliximab. Aim: To evaluate efficiency of ultrasound imaging in the diagnosis and monitoring of perianal fistulas treatment. Methods: 48 patients has been treated due to Crohn’s disease since 2003. 16 patients presented perianal complications of the disease including fistulas. 2 female patients were diagnosed with recto-vaginal fistula. Fistulography, endorectal ultrasound examination (ERUS) with hydrogen peroxide were used in the diagnostic procedure. 9 patients (4 females, 5 males, at the age ranging 16-45) were involved into the study with IFX management. Images were performed before the onset and 10 weeks following therapy to assess the effectiveness of the treatment. ERUS was performed right before the administration of the first dose of IFX to rule out perianal retention. Ultrasound device BK Medical was used to perform the 2D and 3D ultrasound imaging. Results: 9 patients (100%) treated with IFX responded to therapy. Closure of more than 50% fistula’s tract was observed in 8 cases (88%). In 5 (55%) of the patients there was no fistula on ERUS images 10 weeks after the onset of therapy. There was neither retention nor fluid visualized on ERUS. 7 patients were qualified for the further maintenance therapy with IFX. Conclusions: Endorectal ultrasound imaging is an excellent tool in both: diagnosis and monitoring therapy of perianal fistulas in patients with Crohn’s disease. Repeatability and 3D imaging makes it even more attractive regarding the complete visualization of the topography of fistula itself and it’s canal. P069 HEALING AFTER SURGICAL MANAGEMENT OF CROHN’S ANAL FISTULA/ABSCESS, KJ Park PhD, IS Lee MD, EK Choe MD, Seoul National University College of Medicine, Seoul, South Korea Background: Crohn’s anal fistula/abscess is notorious for delayed wound healing and high rate of recurrence after surgical management. However, few reports concerning the detailed analysis of healing time are available. In this study, we intend to review the healing rate and time for Crohn’s anal fistula and/or perianal abscess and access any determining factors. Methods: We analyzed the follow-up data of 25 Crohn’s anal fistula patients (35 operations) who underwent operation by one surgeon. Anal fistula/abscess was into 2 groups simple (superficial, intersphincteric, low-transsphincteric) and complex (high transsphincteric, extrasphincteric, suprasphincteric, horse- ABSTRACT BOOK Poster Papers shoe). Results: Mean age of the patients was 26. 8+/-7. 1 years and there were 5 simple (14. 3%) and 30 (85. 7%) complex fistula/ abscess. All patients with simple type healed without recurrence, and there was no difference in healing time compared with non-Crohn’s patients in the simple type group (42. 4+/-21. 4 vs. 41. 9+/-16. 8 days, P=0. 969). Of the 30 in the complex group, only 22 (73%) healed and there was a significantly prolonged healing time compared with non-Crohn’s patients (207. 2+/-159. 3 vs. 96. 5+/-74. 2 days, P=0. 004). The mean follow-up time for the unhealed patients (N=8) was 607. 2days (range 180 days ~ 1560days) despite multiple surgical interventions. Neither Crohn’s disease activity index (CDAI) value (mean: 141. 6) nor the extent of intestinal inflammation (including rectal inflammation) had relationship with healing time (P=0. 392, P=0. 911). All patients used azathioprine during treatment and infliximab nor prednisolone medication had no statistical significance in healing time (P=0. 73, 0. 59). After healing of primary surgical wound, four (4/22=18%) patients in the Crohn’s complex anal fistula/abscess group had recurrence (at a mean of 877 days) as compared to 1. 7% (2/115) in non-Crohn’s patients with complex type anal fistula/abscess. Conclusion: Postoperative course in simple type of Crohn’s anal fistula/abscess was same as that of non-Crohn’s anal fistula. On the other hand, there was delayed healing and more frequent recurrence regardless of extent of gastrointestinal involvement or medical treatment in the complex type of Crohn’s anal fistula/abscess. Takehito Yoshifuji MD, Jin-ichi Hida MD, Kiyotaka Okuno MD, Hitoshi Shiozaki, Div. of Laparoscopic & Colorectal Surgery, Dept. of Surgery, Kinki University School of Medicine Introduction: We started performing laparoscopic colorectal surgery (LAC) in 1995, since then more than 221 cases have been done at our institution. For the first 3 years, we used laparoscopic procedure only for early stages of colorectal cancer until T1 and therefore we had expanded indications for advanced stage of colorectal cancer. Proposed here is our series of patients undergoing LAC and the description of the learning curve. Method: All the patients undergoing LAC until December 2007 were entered into a database and the following parameters were collected: demographic, blood loss, complications, hospital stay and post-operative follow up. Only patients having all the parameters were then analyzed. Results: Out of 220 patients 91 were analyzed. This corresponded to all cases were consecutively performed from January 2005 to December 2007 when a tighter data collection was adopted. There were 56 (61%) male and 35 (39%) female; the mean age was 66+/-10 y. o. (33-87 y. o. ) The annual clinical data was indicated as for the table. Laparoscopic Surgery P070 WITHDRAWN P071 ROBOTIC ANTERIOR RESECTION OF THE RECTUM, Slawomir J Marecik MD, Leela M Prasad MD, John J Park MD, Advocate Lutheran General Hospital, Park Ridge, IL, University of Illinois Medical Center, Chicago, IL Purpose: Robotic surgery has gained wide acceptance in urology. This technology allows for fine dissection within confined pelvic space. There is growing literature on the use of the new generation robots in major colon and rectal resections. The authors’ goals were to assess the feasibility, safety and efficiency of robotic technology in 35 rectal dissections. Methods: This is a retrospective study of patients undergoing roboticallyassisted resections at a single institution from August 2005 to January 2008. Following IRB approval, the hospital and office charts of 36 patients were reviewed. Data extraction sheets were used to collect information on demographics, operative details, and postoperative course. Results: There were 35 patients (20 female, 15 male), with an average age of 55. 6 (range 28-86), and an average BMI of 29. 8. Of these, 12 patients were operated for cancer, 4 for polyps (including 3 familial adenomatous polyposis cases), 12 for diverticulitis (1 colovaginal fistula, 1 abscess), 5 for rectal prolapse, and 2 for ulcerative colitis. There were 14 anterior resections (AR) with splenic flexure mobilization (SFM), 8 low anterior resections (LAR) with SFM, 5 AR with rectopexy (RPX), 5 total proctocolectomies (TPC, pouch procedures) and 3 abdominoperineal resections (APR). There were 14 total mesorectal excisions performed and 10 rectal reservoir reconstructions. The average operative times were 294 min (AR SFM), 364 min (LAR SFM), 195 min (AR RPX), 461 min (TPC) and 375 min (APR), respectively. The average blood loss was 120 cc. The average lymph node harvest from rectosigmoid was 15. 7. The average length of stay was 5. 5 days for AR, 6. 9 for LAR, 4 days for AR RPX, 5. 2 days for TPC, and 8 days for APR. There were no intraoperative complications or mortalities. There were 5 major postoperative complications (4 small bowel obstructions with one requiring reoperation and 1 pelvic abscess). Five patients (14%) developed superficial surgical site infections, including 3 cases of perineal wound. Conclusion: In the authors’ experience, rectal resections using the current generation of robots can be safely performed without intraoperative complications. This technique is most applicable and very helpful for total mesorectal excision and resection rectopexy. P072 LAPAROSCOPIC SURGERY FOR COLORECTAL CANCER AT OUR INSTITUTE; CAN WE PERFORM A CODIFIED SURGICAL PROCEDURE?, Kazuki Ueda MD, Haruhiko Imamoto MD, Tadao Tokoro MD, Eizaburo Ishimaru MD, www.isucrs.org/ There were 3 cases (3. 3%) of postoperative anastomotic leak in these 3 years, however, we did not experience any in 2007. The improved tasks were identified in: technical proficiency, understanding of local anatomy, codified procedure, environmental arrangement in the OR (the distribution of clinical engineer), and the education for scrub nurse. Conclusions: Surgeons who perform laparoscopic surgery will need skills and anatomical understandings that improve with time and experience. Moreover, we believe that a good OR arrangement, the distribution of clinical engineer and a full education for scrub nurse will be mandatory to perform stress-free laparoscopic surgery. P073 LAPAROSCOPIC HAND-ASSISTED SURGERY IN THE MANAGEMENT OF COMPLICATED DIVERTICULITIS WITH COLOVESICAL FISTULA, Megan Brenner MD, James Yoo MD, UCLA Introduction: Laparoscopic techniques are gaining popularity in the surgical management of colorectal diseases. Handassist devices have been shown to reduce operative time and conversion rates for laparoscopic procedures, and may play an important role in the surgical management of patients with complicated pathology. However, indications for its use are still being defined. Objective: To investigate the use of hand-assisted laparoscopic surgery (HALS) in the surgical management of patients with diverticulitis and a colovesical fistula. Participants: Five consecutive patients who presented with diverticulitis and a colovesical fistula over a 10-week period underwent a laparoscopic, hand-assisted sigmoid colectomy and takedown of a colovesical fistula by a single colorectal surgeon at UCLA Medical Center. Data was gathered prospectively. Results: The mean age of the patients was 68. 8 years. One patient had a BMI of 40, two patients had a history of prior lung transplant and were on immunosuppressive medications, and one patient was 90 years old with aortic stenosis and Waldenstrom’s macroglobulinemia. Four of the five patients had a history of prior abdominal surgery. The diagnosis was suspected by pneumaturia and fecaluria, and confirmed by CT scan in all patients. In addition to sigmoid colectomy, simple closure of the cystotomy was necessary in three patients. There were no conversions. Mean operating time was 236. 6 min; mean EBL 237 cc. Average length of stay was 7. 2 days. One patient developed a wound infection. There were no deaths and no recurrences. Conclusions: Laparoscopic hand-assisted surgery may play a role in the management of high-risk patients with diverticulitis and a colovesical fistula. Pure laparascopic techniques for sigmoid diverticulitis are performed; however, the HALS technique may reduce operative times and conversion rates, and may be even more beneficial for complicated diverticulitis. 83 ABSTRACT BOOK Poster Papers P074 A CASE REPORT OF LAPAROSCOPIC EXCISION OF RETRORECTAL CYSTIC TERATOMA, Won-Kyung Kang PhD, Jong-Kyung Park PhD, Seong-Taek Oh PhD, Eung-Kook Kim PhD, Suk-Kyun Chang PhD, Department of Surgery, The Catholic University of Korea Retrorectal or presacral tumors are rare masses. Its incidence is reported to be 0. 01%. Generally, these tumors have non specific symptoms, and are likely to be found incidentally on CT or MRI scans. Among all presacral masses about 2/3 are congenital, and also about 2/3 are benign. Benign presacral tumors are surgically resected. On the other hand, treatment modalities for pathologic proven malignant tumors include chemotherapy, radiation, or surgery. Based on careful preoperative studies and surgical planning, the anterior or posterior surgical approach is chosen. Although cystic teratomas usually involve the ovaries, few cases report their occurrence in the presacral area. To our knowledge and the references including the Pubmed, no case reports on the laparoscopic excision of presacral cystic teratomas were perceptible, and therefore we present this original case. <case> A 31 year old female patient complaining of right hip pain visited our orthopedics outpatient department. Although simple X-ray did not show any abnormality, MRI revealed a 6. 6 x 5. 7 x 6. 5 cm sized cystic mass (T1; high, T2; low signal) in the right presacral region. Colonoscopy did not show any discernible intra-luminal lesion. Considering the benign nature indicated by imaging studies, the risk of cutaneous fistula and the young age, laparoscopic excision was performed. A ureteral catheter was inserted through a cystoscope just before the operation. Dissection to the presacral area was made in the same manner as the total mesorectal excision. Frozen section biopsy identified a benign mass. Tumor contents were then removed after the dissection of the presacral area. The cyst wall was removed employing an 11 mm port on Right lower quadrant. Permanent pathology confirmed cystic teratoma as expected. The patient recovered without any significant postoperative complication and was discharged in good condition. P075 LAPAROSCOPIC COLECTOMY FOR COLONIC INERTIA, J Sanjay MD, B Safar MD, D Sands MD, E Weiss MD, J Nogueras MD, S D Wexner MD, Cleveland Clinic Florida Aim: Total abdominal colectomy (TAC) is the treatment of choice for patients with colonic inertia refractory to medical therapy. Laparoscopic segmental colectomy has been shown to have certain advantages over open colectomy such as decreased length of stay (LOS), however, its role in colonic inertia has not been well described. Therefore the aim of this study was to compare laparoscopic TAC as compared to standard open TAC. Methods: After IRB approval, a retrospective review was undertaken of all patients prospectively entered into a database at our institution who underwent laparoscopic or laparoscopic attempted TAC (LTAC) for colonic inertia matched with patients who underwent open TAC (OTAC) for colonic inertia from the same registry. Age, gender, BMI, prior abdominal surgery, operative time, complication rate, and LOS were evaluated. Results: 12 females underwent LTAC and were well matched with 12 patients who underwent OTAC. The mean age was 43. 8 years for the LTAC vs. 39. 4 years for the OTAC (p=0. 53). The mean BMI for the LTAC was 21 vs. 21. 8 for the OTAC (0. 61). One person had prior surgery in the LTAC vs. 2 in the OTAC (p=0. 56). The mean LOS was 8. 25 days for LTAC vs. 8. 33 days for OTAC. Mean operative time was 243. 8 minutes for LTAC vs. 164. 2 minutes for OTAC (p=0085). There were 3 complications in LTAC, none in OTAC and one operation was converted from laparoscopic to open. Conclusion: LTAC can be safely performed for colonic inertia, however the operative time and complication rate is significantly higher than OTAC. LTAC for colonic inertia does not offer the advantages that laparoscopic colorectal surgery for other pathologies offers. P076 LAPAROSCOPIC PROPHYLACTIC COLECTOMY FOR FAMILIAL ADENOMATOUS POLYPOSIS PATIENTS, Tetsuro Higuchi MD, Hirotoshi Kobayashi MD, Masayuki Enomoto MD, Kenichi Sugihara MD, Department of Surgical Oncology, Tokyo Medical & Dental University, Graduate School Introduction: Familial adenomatous polyposis (FAP) is an autosomal dominant disease caused by a germline mutation 84 ISUCRS XXII BIENNIAL CONGRESS in the APC gene located at chromosome 5q21. Patients with FAP develop hundreds to thousands of adenomatous polyps, and they are at a nearly 100% risk of colorectal cancer. Surgical management includes prophylactic proctocolectomy with ileopouch anal anastomosis (IPAA) or total colectomy with ileorectal anastomosis (IRA). IPAA has been accepted as the standard operation for FAP patients. However, the operation requires extremely complex procedures, and has a high incidence of postoperative complications, compared with IRA. Moreover, this radical operation affects the stool habit of the patients and compromises their quality of life. To monitor the possible development of rectal carcinoma after IRA, it is important to continue periodic follow-up of the remaining rectum. Aims and Methods: Between 1998 and 2006, laparoscopic prophylactic surgery was performed in 14 patients, 11 male, average age 26 years (range 20 -E65 years). We reviewed some clinical factors in the perioperative period. Results: We have performed 12 IRA and 2 IPAA. Among them, invasive carcinomas developed in the remnant rectal mucosa of 2 IRA cases, one patient had laparoscopic low anterior resection, another had laparoscopic IPAA. We present the technique of laparoscopic prophylactic surgery for FAP. Conclusion: Laparoscopic prophylactic surgery for FAP is a technical alternative of conventional open surgery. By this technique, it is possible to provide a better quality of life in postoperative period and better cosmetic result. P077 CEREBRAL ISCHEMIA AFTER LAPAROSCOPIC OPERATION, Thomas Auer MD, Friedrich Herbst MD, B. Sima MD, G. Gruber MD, B. Salehi MD, KH der Barmherzigen Brüder Wien, Medical University of Graz Case Report: A 47 yrs old female patient was operated on lap. Ileo-cecal resection due to extended ileitis based on a years lasting crohn`s disease. A fistula was found from the ileum to the sigma. The patient was brought to Lloyd-Davis position for the procedure. The preparation of the cecum, ascending colon and sigmoid was performed in a 35° Trendelenburg`s position for approx. 90 minutes. After ileocecal resection, excision of the fistula, ileo-ascendostomy, cholecystectomy was performed due to gallstones. Duration of the operation was 190 minutes. In the early postoperative period, the patient experienced double vision, divergence of the bulbi was observed. Since immediate CT-scan showed no change, MRI 3 days later showed ischemic lesions of the right thalamus. By MR angiography, dissection of the right vertebral artery was found in the V2 and V3 segment. Neurological examination after 8 hours found the patient symptoms free, so she was thereafter. Discussion: Stroke, seizure, cerebral circulatory disorders are the mostly reported cerebral complications after laparoscopic operations. Venous blood congestion, reduction of cerebral tissue saturation, vasospasm could be the causes. Vascular risk factors, duration of pneumoperitoneum and Trendelenburg`s position should be serious factors of risk calculation. P078 LAPAROSCOPIC DIVERTING ILEOSTOMY IS USEFUL FOR THE SURGICAL TREATMENT OF PERIANAL PAGET’ DISEASE, Makoto Watanabe PhD, Akira Tsunoda PhD, Kentaro Nakao PhD, Nobuaki Matsui MD, Mitsuo Kusano PhD, Showa University School of Medicine Department of General & Gastroenterological Surgery Perianal Paget’s disease is a rare entity. The standard treatment for extramammary Paget’s disease is surgical excision, and wide local excision of the skin and subcutaneous tissue in the perianal region is the recommended treatment for noninvasive intraepithelial perianal Paget’s disease in vast majority of reported cases. When we performed reconstruction using skin flaps to cover these areas of tissue loss, we created a diverting ileostomy to avoid wound complication. Generally a mini laparotomy is needed to identify the terminal ileum surely in a diverting ileostomy. We used laparoscopic techniques to obviate the need for laparotomy while creating a diverting ileostomy. In this report we present our experience with laparoscopic diverting ileostomy that was performed for the surgical treatment of perianal Paget’s disease. Surgical Technique: A pneumoperitoneum was established using a closed method with a blunt port, with CO2 insufflation at a rate of 6 L/min. The intra-abdominal pressure was maintained at 10mmHg. A diagnostic laparoscope was placed ABSTRACT BOOK Poster Papers through the umbilical port for initial exploration of the abdominal contents. A 5mm trocar was placed in the left inferior abdomen for introduction of a blunt dissecting instrument to grasp the terminal ileum. After a segment of terminal ileum was identified, this bowel segment was raised against the right anterior abdominal wall at the site of the stoma. A 3cm incision was made in the skin which the ileum was raised against the abdominal wall. The ileum could be extracted under direct visualization through the abdominal wall to create a loop ileostomy. The ileostomy was then matured in the standard manner, and operation was completed. We have performed laparoscopic diverting ileostomy in three patients with perianal Paget’s disease. The mean time of the creation of diverting ileostomy by laparoscopic techniques was 30(25-35) minutes. The postoperative course was uneventful, and all the patients began a regular diet from the next day after operation. Laparoscopic approach for diverting ileostomy reduced postoperative discomfort and ileus, and is useful for the surgical treatment of perianal Paget’s disease. Profilaxis P079 ANAL CYTOLOGY: EXPERIENCE OF THE COLOPROCTOLOGY UNIT FROM CARACAS UNIVERSITARY HOSPITAL DURING 2007. , Carlos Sardiñas MD, Patricia Bravo MD, Yaycira Guillen MD, Nahir Castillo MD, Carlos Rodriguez MD, Katyana Alvarez MD, Yuleiby Flores MD, Norma Oviedo MD, Coloproctology Unit. Caracas University Hospital. Central University of Venezuela Goal: Clinic and cytologic detection of malignat (M) and premalignat (PM) lesions of the anal conduct in patients assisting to the Coloproctology Unit. Place of Elaboration: Examination ward of the Coloproctology Unit at the Caracas University Hospital. Methods: Cytomorfologic analysis of Cytologies taken after being processed with the Papanicolaou technique. Results: During 2007, 284 anal cytologies were processed. 217 Females and 67 males. 224 Resulted with no lesions. Samples inadequate were 25. Premalignant lessions resulted 31 and malignant resulted 4. In premalignant lessions, 4 were females and 27 males. In malignant lesions 2 were females and 2 males. Conclusions: Anal cytology was usefull in detecting up to 14% of lessions from the hole population studied. 88% Of premalignant and 12% of malignant lessions. Innadequate cytologies were 9% which is accord with the experience during the act of taking and processing the sample. We would encourage the coloproctologists and even other specialists to make of the anal cytology a first line profilaxis instrument in anorectal premalignat and malignant deseases. Research P080 ROLE OF SACRAL LIGAMENT CLAMP IN THE PUDENDAL EUROPATHY (PUDENDAL CANAL SYNDROME): RESULTS OF CLAMP RELEASE, Olfat El Sibai, Menoufia University Objectives: Pudendal canal syndrome (PCS) is treated by PC decompression. We investigated the hypothesis that failure of PCD to relieve anal and perianal pain could result from compression of pudendal nerve not only in PC but also in sacral ligament clamp (SLC), i. e. in space between sacrotuberous and sacrospinous ligaments. Methods: SLC release was performed in 21 patients with proctalgia who had not improved after PCD. Pudendal nerve terminal motor latency (PNTML) was higher than normal. SLC release operation comprised entering ischiorectal fossa through a paraanal incision, identifying PN and division of sacrospinous ligament. Results: Treatment was successful in 17 patients and failed in 4. The former showed pain disappearance and improvement in fecal incontinence, perianal sensation and anal reflex. Conclusions: Clinical manifestations and investigative results improved after SLC release in 80. 9% of cases. Assumingly these results denote traumatization of the PN not only in PC but also in SLC.

P081 ADEQUACY OF PROPOFOL ALONE AS SEDATIVE AGENT FOR COLONOSCOPY, Shahrun Niza ABDULLAH Suhaimi MS, MD. Lukman Mohd Mokhtar MD, Mohd Zailani Mat Hassan MS, AZMI MD Nor MS, International ISLAMIC University Malaysia Background: The aim of this study was to assess the efficacy of propofol as sedative agent compared with a combination of tramadol and midazolam as sedo-analgesia for colonoscopy. We assess the degree of tolerance and satisfaction among patients with regards to both methods of colonoscopy using sedation or sedoanalgesia as well as the time needed to reach the caecum and post colonoscopy recovery period. Methods: 65 patients underwent colonoscopy from 1st october 2006 till 30th April 2007. They were randomly assigned to 2 medication regimens. For the propofol group, an initial intravenous bolus of 0. 5mg/kg was given, followed by an intermittent bolus of 10mg (1cc) when necessary. This drug was administered by an Anaesthetist. For tramadol and midazolam group, an intravenous tramadol 25mg and midazolam 2mg was given initially and then the dosage was increased depending on the patients tolerance towards the procedure. The drug was administered to its maximum dose according to the patients body weight. The colonoscopy time was calculated from the time the instrument entering the anus till it reached the caecum. Patient assessments of pain and tolerance were obtained at the time of discharge using visual analog scales of 1 to 5. (1= no pain and 5 worst pain imaginable). Results: 65 patients were randomized in this study ( 34 propofol, 31 tramadol and midazolam). 41 (63. 1%) of the patient were males and 24 (36. 1%) of the patients were females. Malay comprised of 61. 5% Chinese 29. 2%, Indians 4. 6% and others 4. 6%. Conclusions: Using propofol a sedation in colonoscopy provide better tolerance in patients compared to conventional use of tramadol and midazolam. The time for the procedure is shorter when propofol is used. The recovery time from propofol is statistically shorter than the recovery time from tramadol and midazolam (p=0. 044). P082 COLORECTAL ANASTOMOTIC STRICTURE: IS IT CAUSED BY INADEQUATE COLONIC MOBILIZATION?, P Denoya MD, S Shawki MD, D Sands MD, J Nogueras MD, E Weiss MD, S Wexner MD, Cleveland Clinic Florida Anastomotic stricture is a complication which can be seen following intestinal anastomoses. The etiology includes anastomotic ischemia and tension. Splenic flexure mobilization and inferior mesenteric vessel division are methods which are often used to gain length and ensure a tension-free colorectal or coloanal anastomosis. Objective: The study aimed to evaluate whether patients who developed anastomotic strictures after left sided colon resection had the splenic flexure mobilized and the inferior mesenteric vessels divided at the first operation. Methods: Patients referred for reoperation for colorectal anastomotic stricture between 2001 and 2007 were identified through a prospectively-collected perioperative database. Operative reports were reviewed to identify the incidence of splenic flexure mobilization and inferior mesenteric vessel ligation. Results: 22 patients were identified, with mean age of 61 years(29 to 78) and mean BMI of 25. 6. Previous operations included anterior resection(8), sigmoid resection(8), and proctectomy with coloanal anastomosis(6). Previous diagnoses were rectal cancer(11), diverticulitis(8), radiation proctitis after prostate cancer(1), gunshot wound(1), and unknown(1). 18 patients had not had both splenic flexure mobilization and inferior mesenteric vessel ligation previously performed, while 2 patients had only had vessel ligation. Thus, 91% of patients with anastomotic stricture had incomplete left colonic mobilization. The operations performed included excision of the previous anastomosis with a colorectal anastomosis in 8, end-to-end or end-to-side coloanal anastomosis in 3, coloanal anastomosis with colonic pouch reconstruction in 6, and end colostomy in 5. 14 patients were diverted and 12 patients had pelvic drains placed. Conclusion: While this study is limited by its retrospective nature, as only patients who developed strictures requiring surgery were evaluated, the data suggest that lack of complete mobilization of the left colon at the time of first operation is associated with anastomotic stricture formation. This 85 ABSTRACT BOOK Poster Papers retrospective study identified a 10: 1 incidence of incomplete left colonic mobilization in patients with anastomotic stricture. P083 ARE THERE DIFFERENCES IN POLYP TYPE AND DISTRIBUTION IN MORBIDLY OBESE PATIENTS: A COHORT COMPARATIVE STUDY, B Bashankaev MD, M Khaikin MD, R Landmann MD, D Melero MD, Cleveland Clinic Florida Data suggests an increased risk of colorectal cancer in the obese population. The aim of the study is to compare the incidence of colon polyps between obese patients undergoing bariatric surgery versus a non-obese patient cohort. After IRB approval, a retrospective review of prospectively maintained bariatric surgery and endoscopy databases was performed identifying all patients who had bariatric surgery and colonoscopy between February, 2000 to April, 2007. This Surgical Morbidly Obese Group (SMOG) was matched to a Non-Obese Group (NOG) of patients undergoing colonoscopy by age and gender. BMI before surgery and at time of colonoscopy, age, gender, procedure, colonoscopic findings, and pathology were reviewed. Seventy case-matched patients were gathered from the 2332 patient bariatric surgery (SMOG) and the 2165 patient endoscopy (NOG) databases. There was a statistically significant difference in BMI at time of colonoscopy (31 vs. 28, p<0. 04). The SMOG and NOG were equally balanced for high-risk patients (21. 4% vs 25. 7%). SMOG colonoscopy was postoperatively performed after a mean period of 23 (1-55) months. Two-thirds of patients in both groups had no polyps (70% SMOG, 77% NOG). Most polyps were single and were equally distributed between the right and the left colon. Half of the polyps in both groups were hyperplastic measuring 3 - 4mm. No cancer was identified in the NOG; however, adenocarcinoma was found in 2 patients (8. 3%) in the SMOG - 1 each in the cecum and sigmoid. Both patients were not high risk for colorectal cancer and postoperative colonoscopy was performed at 55 and 33 months, respectively. The incidence of colorectal polyps and cancer was not significantly different between SMOG and NOG patients during a mean postoperative period of 2 years. Furthermore, polyp distribution and pathologic characteristics were similar between both groups. Though not statistically significant, this study shows a trend towards development of malignant polyps in morbidly obese patients. Long-term follow-up with preoperative and postoperative colonoscopy is needed to accurately determine any role of bariatric surgery in the development of colorectal cancer. Stomas P084 PREOPERATIVE STOMA MARKING WITH HENNA: IMPROVEMENT OVER PERMANENT TATTOOING, J Sanjay MD, B Safar MD, S Shawki MD, H Marquez MD, M Boyer MD, J Genua MD, D Sands MD, E Weiss MD, J Nogueras MD, S Wexner MD, Cleveland Clinic Florida Stoma creation is a common surgical procedure. Preoperative stoma marking and education by an enterostomal therapist has been shown to decrease postoperative stoma related complications. We propose the use of henna as an improvement over permanent tattooing for preoperative stoma site marking. Methods: A prospective non-randomized pilot study was performed in which 20 consecutive patients were preoperatively marked with henna. Patient satisfaction and the effectiveness of henna were evaluated. Results: Twenty patients (10 females) were enrolled; mean age 55. 1. Seventeen of 20 markings were visible at surgery. Two of the three failures were poorly visible; one was not visible at surgery. All patients stated henna was an improvement over permanent tattooing. Conclusion: Preoperative stoma marking with henna is a safe and effective alternative to permanent tattooing with India ink. Henna use should strongly be considered for patients scheduled for surgery with possible ostomy creation within 2 to 14 days of preoperative stoma marking by enterostomal therapist. P085 NEW SKIN CARE ELEMENT FOR PERI-STOMAL SKIN ULCER WITH IBD, Katsuhisa Shindo, MD PhD, Satoru Numata BA, Tetsuji Iwasaki MS, Kinki University School of Medicine, Osaka Japan and Alcare Co. , Ltd. , Tokyo Japan Purpose: Ileostomy with IBD makes often the skin trouble that is not controlled by a dermatologist or an ET. Ceramide involved in 86 ISUCRS XXII BIENNIAL CONGRESS the skin barrier is to be evaluated for the treatment of peristomal ulcer. Methods: Fundamental skin tests in five cases with normal peristomal skin of about 20 years history and in two IBD cases with ulcerated peristomal skin of several years history: Skin surface pH by F-15 pH meter with a skin probe (HORIBA), Transepidermal water loss (TEWL) by AS-TW2 (ASAHI BIOMED), and Macro/Derma-scopic inspection, before and after application of the ceramide vs. conventional skin barriers. Results: (1) Ceramide kept skin surface pH constant in all tested skins in spite of fecal contamination: PH 4. 9 - 5. 1, (2) Ceramide put TEWL lower value (16. 4 - 19. 6g/m²h) in all tested skin while reuse of the conventional skin barrier recovered the skin to the usual one (26. 0 - 30. 9g/m²h) in spite of wide range TEWL 10. 5 - 84. 7 before the ceramide application, (3) All peristomal skin ulcer healed completely with ceramide but reuse of the conventional skin barrier made ulcer recur. Conclusions: Skin barrier with ceramide is effective for the treatment of peristomal ulcer by keeping skin pH normal and TEWL lower due to maintaining intercellular lipids intact. Surgical Techniques P086 LAPAROSCOPIC COLECTOMY COMBINED WITH MINILAPAROTOMY APPROACH FOR SAFETY OPERATION IN PATIENTS WITH COLORECTAL CANCER. , Kyoji Yamada MD, Keiichirou Onoda MD, Shinichirou Noda MD, Norihio Okamoto MD, Reina Kyoui, Ryuiichi Ohshima, Kiyoshi Narahashi MD, Hideaki Kaneko MD, Takehito Ohtubo MD, Dept. G. I. Surg and General Surg. Kawasaki Munincipal Tama Hospital Laparoscopic colectomy have been rapidly improved for advances of surgical technique and instruments. Although many japanese medical institutes apply this surgery, Several technical difficultes are still exsist. For example lymphnodes dissection or intracorporeal anastomosis are difficult for beginner of laparoscopic surgery. These difficulties are related with operative complication of bleeding or anastomotic leackage. Minilaparotomy approach for abdominal operation is one of less invasive surgery. This operation use several unique instrument and technique. Our institutes performed Laparoscopic colectomy combined with minilaparotomy for safety operation. We introduce this right hemicolectomy techinique for colon cancer. (Operative method) i1jInsertion of laparoscopic trocher (4ports). i2jLigation of Ireocecal artery under laparoscopic procedure. i3jMobilization of the right colon from the retroperitoneum. i4j4~5cm length median incision (minilaparotomy). (5)Division of oral and anal side intestine using moving window method (6)Lymphonodes dissection for the root of middle colic artery form minilaparotomy. (7)Intestinal anastomosis. We have performed 20 cases of this operation for colororectal cancer. There was no complication without wound infection. This operation is less invasive similar to laparoscopic surgery. We recommend this operation for beginner of laparoscopic surgery. P087 THE CIRCULAR STAPLER IN COLORECTAL SURGERY - 30 YEARS ON, Bruce Waxman MSc, T C Nguyen, M Fisher, Dandenong Hospital, Southern Health Background: Whereas Russian engineers and surgeons were the first to produce a circular stapler, with a single row of staples, that simultaneously created a circumferential row of staples, and resected two rings of bowel to produce an end to end inverted anastomosis, the USA version, with a double row of staples was released in 1977 and data first published in 1978, 30 years ago. Discussion: This review will discuss the progress over the last 30 years with an emphasis on terminology, the effect of design on anastomotic healing and complications specific to the circular stapler (CS). Terminology: We recommend the terminology described by Waxman et al in 1995. Design: The original design of the bridge and has changed little over 30 years, as an identical anastomosis is produced now as 30 years ago, viz., an inverted anastomosis that heals by secondary intention, with fibrous scar tissue. Most design changes have been in the staples, the shape of the body and handle, the introduction of a spike and disposability. Complications unique to the CS are: 1. Anastomotic stenosis 2. Failure of staple closure. Conclusion: Little has changed in the basic design of the circular stapler at the “firing line”. Complications unique to the CS are related to the design and with regard to stenosis have not been addressed. A CS with ABSTRACT BOOK Poster Papers a single row of absorbable staples would solve the problem. We may need to wait another 30 years. References: 1.

Philadelphia 1995 pp. 778 – 811 P088 CLINICAL CHARACTERISTICS OF HAND-SEWN CIRCUMFERENTIAL MUCOSECTOMY IN HEMORRHOIDS, Jung G Kang, Hong J Shim MD, Jong T Park MD, Yoon J Choi* MD, Surgery and *Pathology, Ilsan Hospital, National Health Insurance Corporation, Yonsei University Purpose: Stapler hemorrhoidectomy (hemorrhoidopexy) does not excise hemorrhoid tissue, but instead repositions the prolapsed hemorrhoid. We introduced hand-sewn circumferential mucosectomy under direct vision as a new hemorrhoidectomy method and evaluated its safety and effectiveness for the surgical treatment of hemorrhoids. Method: We performed 108 handsewn circumferential mucosectomies between June 2003 and December 2006. We evaluated the operating time, postoperative course, and complications. Pain was evaluated using a visual analog scale. Results: The mean patient age was 48 years and the proportions of males and females were similar. The most common indication was third-degree hemorrhoids. The mean operating time was 37. 7 minutes and most of the operations took between 20 and 40 minutes. The average postoperative pain score was 5. 0 on the day of surgery and 3. 9 on the second postoperative day. The time to the first bowel motion and the length of the hospital stay averaged 1. 3 and 2. 5 days, respectively. The mean time to return to work was 5. 2 days. There were no serious complications with the hand-sewn circumferential mucosectomy. Postoperative complications occurred in 31. 5% of cases. Urinary complications were the most common. Conclusions: A handsewn circumferential mucosectomy is safe for the treatment of hemorrhoids and there are no serious complications. The operative pain, postoperative course, time to return to work, and nature of complications are acceptable, although the operating time is longer. A hand-sewn circumferential mucosectomy is considered an effective new alternative for the surgical treatment of hemorrhoids. P089 ONE CASE OF PRIMARY POSTERIOR PERINEAL HERNIA REPAIRED BY AN EXTRAPERITONEAL TECHNIQUE, T Wada MD, M Hisada MD, Y Mori MD, K Katsumata, A Tsuchida, T Aoki, Tokyo Medical University Perineal hernia is a rare disease and, there are various surgical procedures for it, including laparotomy, episiotomy, and combination of laparotomy and episitomy, and recently, laparoscopic surgery has also been performed. Herewith, we report that we experienced primary perineal hernia repaired by an extraperitoneal technique and a good outcome was obtained. Case: A 63 year-old female. Paroxysmal spontaneous pain was noted in the left gluteal region, an approximately 10-cm tumor mass was detected in the left gluteal region with the patient in the upright position, which was elastic soft and could easily return to the pelvic cavity when pushed, and an approximately 4-cm hernial orifice was palpated. Under general anesthesia, an approximately 10-cm-long incision was made in the median lower abdomen with an upper margin on the pubis at the lower end, and subcutaneous fatty tissue was incised with an electric scalpel. Rectus abdominis fascia was incised in the median line to reach the anterior peritoneal cavity. Bluntly detaching below the left rectus along the left pelvic side-wall, a hernial sac penetrating the pelvic floor to prolapse in the left rectum was found. The adhesion between the hernial sac and surrounding tissues was sharply detached. Thereby, the levator ani muscle was exposed, and there was a gap in the ischial region and pubic region, and when the gluteal skin was pushed from outside, this gap was penetrated, which revealed this to be the herniac orifice. This gap was sutured and closed with 3-0 Vicryl. Moreover, a ø10-cm polypropylene mesh (Bard Modified Kugel TM Patch, Davol, Inc. ) was placed to completely cover the hernial orifice, and the levator ani muscles above and below the gap were fixed with a 3-0 Vicryl stitches. The postoperative course was good, and the patient was able to walk the next day and take meals. Left gluteal pain disappeared, and no signs of recurrence have been detected to date. www.isucrs.org/ P090 OUTCOME OF DELORME PROCEDURE FOR TREATMENT OF RECTAL PROLAPSE, Mohammad Sadegh Fazeli MD, Amir H. Lebaschi MD, Ali Reza Kazemeini MD, Imam Medical Complex Objective: To evaluate the outcome of Delorme procedure (transanal mucosal reefing) in treatment of patients with rectal prolapse. Patients and Methods: In the department of colorectal surgery at Imam Medical Complex (Tehran University of Medial Sciences), in a prospective fashion, 48 patients with rectal prolapse underwent transanal mucosal reefing. After the procedure the patients were followed up. Results: There were 26 males and 22 females. Then mean age was 39 years (range: 17-78 years). Thirteen (27%) patients had only a history of chronic constipation as the underlying condition. Nineteen (39%) had a history of previous coloractal/anorectal surgery. Twelve (25%) patients had fecal and/or gas incontinence. After the procedure, the patients were followed up for a mean period of 24 months. One patient (2%) reported recurrence of the prolapse, who then underwent perineal sigmoidectomy. There were 3 new cases of fecal/and or gas incontinence, and all resolved within 1 year postprocedure. Of the 12 patients with baseline incontinence, only 2 patients were still incontinence after 24 months. There were no cases of sexual or urinary dysfunction. Conclusion: Although Delorme procedure is said to be useful only in selected cases of rectal prolapse, this study indicates a very high rate of success in unselected patients. Delorme procedure may be used as the initial surgery for these patients. P091 AN IRRIGATION TECHNIQUE TO AID IN THE MUCOSAL DISSECTION IN THE DELORME OPERATION, Bruce Waxman MSc, T C Nguyen, W M K Teoh, M Fisher, Dandenong Hospital, Southern Health Background: The difficult part of the Delorme procedure is dissecting a plane between the mucosa and internal sphincter particularly if there is bleeding or scar tissue. Moreover, it is best to avoid full thickness dissection of the rectal wall. We have developed an irrigation technique to aid in this dissection. Method: Patient is placed in the lithotomy position. The rectum is prolapsed with several Babcock forceps. The submucosa is infiltrated with 0. 5% Marcaine with 1/200, 000 adrenaline using a 23 gauge needle in a circumference 2 cm from the dentate line. Diathermy dissection with a needle point tip is commenced at the same site as the infiltration. The free edge of the mucosa is grasped with Babcocks and irrigation commenced with 1. 5% glycine delivered with a urology giving set attached to a mixing cannula at body temperature. The irrigation fluid is directed at the line of dissection using the mixing cannula allowing diathermy without the problem of electrolysis. Clear views of the “white” line at the junction of the sphincter and the “pink” mucosa are obtained. Moreover, the gravity feed of the irrigation provides a degree of hydro-dissection which further opens up the planes. Results: We have used this technique in the last 15 patients without any full thickness rectal defects Discussion: We believe the advantages of this irrigation technique are: 1. Providing improved visualisation of the plane. 2. Hydro-dissection. 3. Washing away of any blood. 4. Potentially reducing the chance of a full thickness defect. P092 RESEARCH AND APPLIANCE OF REUSABLE PPH STAPLER, Gang Ma MD, GuiSheng Liu MD, XiangLong Liu MD, Tianjin UMC, China The most difficult problem to popularize the use of PPH technique in developing country like China is the expensive cost owing to the gun is impossible to be re-used. China now has produced the PPH gun but they only produce the disposable gun, then it is still in relatively expensive price and the disposed gun is also a source of pollution. In order to avoid such defect, we designed a new reusable PPH gun and have used it to perform the PPH in 408 cases all with satisfactory result. The design of the reusable stapler has used metal EEA stapler of USSC as reference, it¡¯s disposable cartridge and shape are similar to EEA gun, but its long central rod can be totally pull out from the body of stapler. The construction of this new PPH stapler is more compact, light in weight, easily handle, simply strip down and sterilize after usage, mounting of the new staples is not difficult, then one gun could be 87 ABSTRACT BOOK Poster Papers used repeatedly for many times. This new device is more feasible for developing country, even though for developed country. P093 DIAGNOSTIC YIELD OF COLONOSCOPY IN PATIENTS WITH COLORECTAL SYMPTOMS, zailani Mat-Hassan MD, Junaini Kasian MD, Khairussaleh Jalaludin MD, Yan Yang Wai MD, Harbhajan Singh MD, Kyaw Tin Hla MD, Nasser MuhamadAmjad MD, Azmi Md-Nor MD, Department of Surgery, Faculty of Medicine, International Islamic University Malaysia (IIUM), Kuantan, Pahang, Malaysia Background and Study Aims: Colonoscopy is the gold standard for the diagnosis of colorectal diseases. The clinician rely on patients symptoms, clinical signs, laboratory data, expert knowledge of the literature and personal experience to decide which patients require colonoscopic examination. Certain clinical indications produce a higher diagnostic yield at colonoscopy than others. We conducted a prospective study to evaluate the yield of colonoscopy in patients with colorectal symptoms and to determine which symptom(s) has a higher yield in detecting neoplastic lesion. Our study aims to determine the relationship between the colorectal symptoms with the colonoscopic findings and identify which symptoms have more weightage in term of clinical significance. Patients and Methods: A total of 583 patients with symptoms of colorectal neoplasm, namely; per rectal bleeding, altered bowel habit and abdominal pain were included in the study. Diagnostic yield was defined as the ratio between significant findings detected during colonoscopy and the total number of procedures performed for that indication. Results: In the study, 55. 7 % of patients were male. According to age, there were 48. 4% of patients were between 50 and 70 years of age, 39. 6% were between less than 50 years of age and 12. 0% were more than 70 years old. According to the study, a combination of per rectal bleeding and alteration in bowel habit constitutes majority of cases who underwent colonoscopic examination (32. 4% and 26. 6% respectively). Among the patients who underwent colonoscopy, 53. 7% of patients had positive findings and less than one third of them were diagnosed to have either malignant growth or polyps. Among those with positive findings, 29. 4% presented with per rectal bleeding and 19. 4% had alteration in bowel habits. Conclusion: The symptoms of rectal bleeding and alteration in bowel habit have a higher diagnostic yield among symptomatic patients who underwent colonoscopic examination. P094 TRANSANAL ENDOSCOPIC LOCAL EXCISION OF RECTAL TUMORS - CLINICAL AND FUNCTIONAL RESULTS OF 90 PATIENTS. , Piotr Walega PhD, Roman M Herman PhD, Jakub Kenig MD, Tomasz Cegielny MD, Marcin Nowak PhD, Michal Nowakowski PhD, 3rd Department of General Surgery Jagiellonian University Collegium Medicum Transanal endoscopic excision of rectal tumors is an accepted sphincter preserving technique in rectum surgery. Detailed preoperative diagnostic procedures (histopathology, endosonography) and functional assessment (manometry, electromyography) are crucial for proper patients selection. Aim: To determine clinical and functional results of patients undergoing local excision for benign and malign lesions. Material and Methods: 90 patients (54 male, 46 female, mean age 68. 4) treated for rectal tumor with transanal endoscopic rectal microsurgery technique at Department of Surgery. To avoid postoperative sphincter dysfunction NO ointment was routinely applied. Results: 75 patients were operated on for benign rectal tumors, 6 for malign disease (T1) and 4 patients due to miscelanous reasons (solitary ulcers, rectum stenosis, rectovaginal fistula). Full-thickness excision was performed on 76 patients and submucosal local excision on 14. The mean distance from the anal verge was 10. 6 cm. 34% of the lesions were located on the anterior wall, 40% on the posterior and 17% on the side wall. The mean operative time was 80 min (range 30-180 min). Average blood loss was 45 ml (range 0-150 ml). The mean length of stay was 3. 6 days (range 1-11 days). Peri- and postoperative mortality was 0, 0%. Complication included urinary retention (4), bleeding (2), wound dehiscence (1), rectocutaneous fistula (1). Postoperative fecal incontinence was observed in 3 patients. In the follow-up time between 6 and 46 months local recurrence rate reached 6, 7% in the adenoma group and up to 30% in the malign diseases group. Conclusions: Transanal endoscopic rectal 88 ISUCRS XXII BIENNIAL CONGRESS operation is a safe and cost efficient procedure for local excision of selected patients with recital tumors. It significantly reduces the number of postoperative functional disturbances what allows to maintain good quality of life with acceptable local recurrence rate and postopeative morbidity. Sphincter protection using nitroglicerin ointment reduces also almost entirely possibility of sphincter damage due to introduction of operational rectoscope. P095 THE EFFICACY OF INTRAOPERATIVE COLONOSCOPY FOR STAPLED ANASTOMOSIS IN THE TREATMENT OF RECTAL CANCER, Toshiyuki Enomoto MD, Y Saida MD, Y Nakamura MD, K Takabayashi MD, R Watanabe MD, A Otsuji MD, M Katagiri MD, S Nagao MD, S Kusachi MD, M Watanabe MD, J Nagao MD, Toho University Ohashi Medical Center Third Department of Surgery We have performed intraoperative colonoscopy for colorectal resection with transnanal stapled anastomosis to eliminate intra- and postoperative complications since January 2006. In this study, we report the efficacy of this technique based on the evaluation of cases that could successfully avoid complications. Fifty-three cases of transanally stapled anastomosis from a total of 68 rectal cancer cases of our department during January 2006 and December 2007 were evaluated. We performed intraoperative colonoscopy for all of the 53 transanlly stapled anastomosis cases. This technique is beneficial because staple line and bleeding of anastomosis can be examined under direct inspection. We experienced three abnormal findings(5. 7%). We created diverting ileostomy for Two cases with imperfect anastomosis. The other case with anastomotic lesion bleeding was treated with clipping. P096 RECONSTRUCTION OF ANAL CUSHION LIKES TO TREAT ANAL INCONTINENCE DEVELOPING AFTER TOO EXTENSIVE HEMORRHOIDECTOMY: REPORT OF A CASE, In-Geun Seo MD, Arumdaun Woori Clinic Purpose: Fecal incontinence after hemorrhoidectomy may occur and is socially incapacitating. There has been no report of effective treatment for fecal incontinence caused by loss of the anal mucosal folds and cushions. The author reports a case, which underwent reconstruction of anal cushions for management of anal incontinence complication after too extensive hemorrhoidectomy. A Case Report: A 39-year-old male patient presented to my clinic with profuse foul-odor discharge and pain after hemorrhoidectomy, which was performed using laser under spinal anesthesia for prolapsing hemorrhoids at another clinic three days previously. Rigid proctosigmoidoscopy revealed an extensive operative wounds and multiple thrombi in the anus. To relieve painful anal symptoms, operative removal of thrombi was performed under local anesthesia by the author. He had no bowel movement after the hemorrhoidectomy, while he had regular bowel movement everyday before. Eleven weeks after the previous henorrhoidectomy he visited my clinic and complained anal incontinence. Fecal soiling was noted 8 times since the previous henorrhoidectomy. Digital examination and rigid proctosigmoidoscopy revealed flat extensive hard scar tissue without any prominent anal cushions or mucosal folds. Saline test revealed anal leakage of saline. Anal ultrasound revealed no defect in the internal and external sphincters. Therefore reconstruction of anal cushion like folds was performed under local anesthesia by the author. The reconstruction technique included longitudinal division of the mucosa and anoderm with transverse closure. He had not complained fecal soiling since the reconstruction surgery. There was no anal leakage of saline on saline test performed nineteen days after the reconstruction. Anal cushions are a part of normal anorectal anatomy and are important in the continence mechanism. Therefore, extensive removal may result in varying degrees of incontinence. The reconstruction of anal cushion likes is an effective treatment for anal incontinence resulting from loss of anal cushions after extensive hemorrhoidectomy. P097 A NEW STAGED APPROACH FOR THE THROMBOSED CIRCUMFERENTIAL HEMORRHOIDS WITH ANAL FISSURE TO AVOID COMPLICATIONS AND TO REDUCE OFF-WORK; REPORT OF A CASE, In-Geun Seo MD, Arumdaun Woori Clinic Purpose: In an attempt to avoid devastating complications such as anal stricture, incontinence, and wet anus after the one-stage surgery, I utilized a simplified procedure in step-by-step approach. ABSTRACT BOOK Poster Papers In a case of the thrombosed circumferential hemorrhoids with anal fissure, the one-stage hemorrhoidectomy can be associated with significant morbidity. The one-stage hemorrhoidectomy has been associated with severe postoperative pain, anal stenosis and deformity with widespread fibrosis, ectropion or incontinence. The author reports a case of ambulatory staged operation under local anesthesia, which avoided these problems. A Case Report: A 41-year-old man presented with severe anal pain, swelling and anal bleeding. Physical examination revealed thrombosed circumferential hemorrhoids and anal fissure. On the day of the first visit, anal fissure operation and extracting thrombi with a skin punch were performed under local anesthesia www.isucrs.org/ on outpatient basis. Seven days after this operation, the swelling was resolved. Therefore the second procedure including excision and ligation of the hemorrhoids was performed under local anesthesia on outpatient basis. During and after these staged procedures, no parenteral analgesic were required. A few doses of oral analgesics were used. He could return to usual activity the next day after operation. The result after the staged procedure was an accurate reconstruction of a normal state with respect to anatomy and function. Staged approach is effective to avoid surgical complications. I recommend staged operation if there is any risk of complications after the one-stage operation or when a patient needs early return to work. 89 Notes 90 ISUCRS XXII BIENNIAL CONGRESS
