Nel corso della nostra esperienza abbiamo testato molti materiali atti a coadiuvare il chirurgo nella prevenzione di questa complicanza. In questo articolo analizziamo i risultati ottenuti a partire dal 2005 utilizzando una spugna medicata di collagene rivestito di fibrinogeno e trombina (Tachosil ®). La fistola biliare si è verificata nel 3.9% dei casi di resezione elettiva e nel 5.1% dei casi di emostasi per trauma epatico. I buoni risultati sembrerebbero indicare che il chirurgo epato-biliare può contare su un emo-biliostatico locale di discreta efficacia. Parole chiave: chirurgia epatica, biliostasi, spugna di collagene Summary How to improve biliostasis in liver surgery. A. Frena, F. Martin One of the most fearful complications following hepatic resection is the onset of a biliary fistula. We have attempted to improve intraoperative biliostasis to minimize the risk of postoperative fistula development by testing different materials. In the early 2005 we began employing a collagen sponge coated with fibrinogen and thrombin (Tachosil ®). In our clinical experience, prior to sponge use, a biliary fistula developed in 3.9% of elective resections and 5.1% of surgical procedures for liver trauma. Until now there were no postoperative bile leaks in the patients treated with Tachosil. Key words: liver surgery, biliostasis, collagen sponge Chir Ital 2006; 58, 6: 793-795 During the last two decades, standardisation of hepatic resective treatment has significantly reduced mortality and morbidity rates1. Anatomical resection, the use of a standardised technique or of manoeuvres such as the hanging manoeuvre, and increasingly effective haemostasis led to a reduction in postoperative complication rates (4-7%)2. Despite these advances, one of the most feared complications following hepatic resection is the occurrence of a biliary fistula, namely bile leakage through small lesions in the biliary ductules following parenchymal transection. Although numerous intraoperative methods for the detection of bile leaks – from injection of methylene blue dye in the cystic duct to assessment of white pads placed on the transected surface – were developed in practice and chemical substances such as 793 793-795_frena 24-11-2006 15:16 Pagina 794 Chirurgia Italiana TECNOLOGIA E TECNICA OPERATORIA/ TECHNOLOGY AND SURGERY TECHNIQUE sealants and celluloses 3 were manufactured for fistula management, the problem of biliostasis is still debated worldwide. This is demonstrated by the numerous techniques described in the international literature, yielding a large amount of data from which it is difficult to extrapolate methodological and/or clinic evidence due to their lack of homogeneity. Our experience with hepatic resection began in 1995.We have attempted to improve intraoperative biliostasis in order to minimise the risk of postoperative fistula development by testing different materials. Finally,in early 2005,we began employing a collagen sponge coated with fibrinogen and thrombin (Tachosil®). This is a medicinal product which was recently introduced on the Italian market. Its efficacy in second-level haemostasis (following primary haemostasis achieved with stitch and clip placement) has already been tested in international controlled studies4. Before applying the product, the resected surface must be cleaned of blood and other fluids and subsequently the sponge, moistened with saline solution, can be applied, gently pressing for 3-5 minutes (Fig. 1). We advocate application using a moist pad to avoid the sponge from sticking to the surgeon’s gloves. In our clinical experience,prior to sponge use, a biliary fistula developed in 3.9% of elective resections (4/103 cases) and 5.1% of surgical procedures to treat bleeding due to hepatic trauma (4/79 cases)5. In contrast, there were no postoperative bile leaks in the 14 patients (11 hepatic resections and 3 traumas) treated with the collagen sponge coated with fib- 794 2006 - vol. 58 n. 6 pp 793-795 Fig. 1.

Although the limited number of cases do not constitute clinical evidence, it should be noted that hepatobil- iary surgeons can rely on local products for haemo- and biliostasis, enabling them to carry out hepatic resection safely (Fig. 2) or post-traumatic liver haemostasis. Reduced or zero incidence of bil- iary fistula has a positive impact on both patients (lower septic complication and re-operation rates) and institutions (shorter mean hospital stay and reduced costs).
