22/10/2013 1 Nieuwe chirurgische technieken: what the future holds
22/10/2013 Nieuwe chirurgische technieken: what the future holds Future is the end of an evolution • • • • What is the evolution? Future is surgery? Which surgery? When surgery? OBESITY Mechanical Rationale BARIATRIC SURGERY Matthias Lannoo Abdominale heelkunde VBG/MASON BARIATRIC SURGERY DISEASE Behavioral problem - Genetically determined - Metabolic alteration - Chain reaction - Exces lipid =catalysator NEUROHORMONAL by modification of the gastrointestinal tractus Gastric banding NEUROHORMONAL by modification of the gastrointestinal tractus 1 22/10/2013 Evolution of Bariatric surgery in Belgium BANDING GASTRIC BYPASS Mechanical view Gut talks to the brain view RYGBP Hunger & Satiety Hunger & Satiety “Atkinson’s experiment” PYY and GLP-1 levels after RYGB in rats Hunger & Satiety PYY and GLP-1 levels after RYGB in humans PYY p<0.001 GLP-1 Sham Bypass p<0.001 Atkinson RL et al, Am J Physiology 1982 Bueter M et al, Physiology & Behaviour 2011 Le Roux CW et al, Ann Surg 2006 & 2007 2 22/10/2013 Hunger & Satiety during Food restriction p<0.001 p<0.001 p<0.01 p<0.01 p<0.001 MECHANISMEN: DIABETES Hunger & Satiety after Food restriction Blocking gut hormones with Octreotide RYGB Islet Insulin deficiency LAGB p<0.001 Pancreas Alpha cell produces excess glucagon Excess glucagon Diminished insulin Beta cell produces less insulin Diminished insulin Hyperglycemia Muscle and fat Liver Sham ad lib Excess glucose output RYGB ad lib RYGB food restricted Bueter M, Lutz TA, le Roux CW et al., unpublished MECHANISMEN: DIABETES Food preference in Sleeve Insulin Ingestion of food GI tract Le Roux CW et al, Ann Surg 2006 & 2007 SLEEVE GASTRECTOMIE Glucose dependent Insulin resistance (decreased glucose uptake) from beta cells (GLP-1 and GIP) Release of incretin gut hormones Active GLP-1 and GIP Pancreas Beta cells Insulin increases peripheral glucose uptake Blood glucose control Alpha cells Glucagon Increased insulin and decreased glucagon reduce hepatic Adapted from Brubaker PL, Drucker DJ Endocrinology 2004;145:2653–2659; Zander M et al Lancet 2002;359:824–830; glucose output Ahrén B Curr Diab Rep 2003;3:365–372; Buse JB et al.

WEIGHT LOSS is IMPORTANT gastric plication Failed conservative treatment SURGERY WEIGHT REGAIN IS STRONGLY ASSOCIATED WITH RELAPSE OF DM Lower preoperative BMI is also contributing factor Possible mechanisms: -Increased calory intake -Increased fat mass -Adaptation of the gut Further research is needed BANDING OF THE GASTROJEJUNOSTOMY Surg Obes Relat Dis. 2010 DiGiorgi M, Bessler M. 9 22/10/2013 CONCLUSION • EVOLUTION = o o o Better characterization of the metabolic patient(not BMI) Patient tailored surgery Better follow up FUTURE = SURGERY SLEEVE GASTRECTOMIE KNOWLEDGE • FUTURE = o o Disease and patient specific Less invasive techniques/ pharmcotherapy 10
