Objectives What is sleeve gastrectomy What are the indications for sleeve gastrectomy How is sleeve gastrectomy different from roux-en-y gastric bypass
Laparoscopic Surgery Several small incisions rather than a large incision Very few wound infections Very few hernias Short hospital stay Less pain, faster return to work
Sleeve Gastrectomy Generates weight loss by restricting the amount of food that can be eaten. Stomach is stapled and divided vertically, which removes 80-85% of the stomach. Remaining pouch, or sleeve, is about the size of a banana. It allows for normal digestion and absorption. Food consumed passes through the digestive tract in the usual fashion which allows it to be absorbed.
Evolution of Sleeve Gastrectomy Sleeve is first part of Duodenal Switch operation In high risk and super-obese DS was done in 2 stages completing sleeve gastrectomy first Weight loss results with sleeve alone obviated need to complete 2 nd stage in majority of patients Restriction alone not sole mechanism at play resulting in superior weight loss Removal of gastric fundus which contains ghrelin producing cells thought to play a major role
Indications for Sleeve High risk pts 2 0 to medical comorbidities Super-obese pts Pts who need to be on lifelong steroids Pts dependant on NSAIDS/ASA Pre- or post-transplant pts, or pts on immunomodulating drugs.and others
Sleeve Gastrectomy Results 60-75% excess weight loss Weight loss occurs within 1 to 2 years 65% remission of diabetes 80% remission of sleep apnea 87% remission of hypertension 80% remission of dyslipidemia Qualify for joint replacement
Sleeve Gastrectomy Complications Mortality 0.2% Deep vein thrombosis/ pulmonary embolism 1-3% Bleeding 1-3% Staple line leak.5-1% Wound infection 1% Re-operations <1% Re-admissions <5% GERD 5-30%
Bariatric Surgery Gastric Bypass 1. A small pouch is separated from the top of the stomach and sealed. 2. Staples are used to create the seals. 3. The small intestine is cut and attached to the new stomach pouch. 4. The section of small intestine that descends from the bypassed stomach is reconnected to the small intestine that descends from the new pouch to create a Y shape. 1 3 4 2
Roux-en-Y Gastric Bypass Restrictive Egg-sized gastric pouch Creates satiety Enforces proper portion size Malabsorption Decreased nutritional calorie absorption Dumping Horrible but not dangerous feeling Self-limiting 1 3 4 2
Gastric Bypass Results 60-75% excess weight loss Weight loss occurs within 1 to 2 years 80% remission of diabetes 80% remission of sleep apnea 87% remission of hypertension 80% remission of dyslipidemia Qualify for joint replacement
Gastric Bypass Complications Mortality 0.4% Deep vein thrombosis/ pulmonary embolism 1-3% Anastomotic leak 1-3% Bleeding 1-3% Wound infection 1% Marginal ulcer 5% Internal hernia 5% Re-operations 5-10% Re-admissions <5% Vitamin and mineral deficiencies up to 90%
Advantages of Sleeve vs LRYGB No risk of marginal ulcers No risk of malabsorption No risk of internal hernia Fewer complications overall Quicker procedure, less OR time
