Surgical options • Restrictive • Malabsorptive • Combination
Restrictive Procedures • A small pouch is created, which limits the food patients can eat • Pouch fills quickly, feel satisfied • Examples of restrictive bariatric procedures: • Gastric Banding • Sleeve Gastrectomy
Malabsorptive procedures • Rarely performed • High long term complications
Combination procedures • Small pouch, limiting the amount of food a patient can eat • Small intestine is rerouted, food bypass some small intestine • Absorb fewer calories. • Examples of combination bariatric procedures: • Gastric bypass • Biliopancreatic diversion with doudenal switch
Adjustable Gastric Band • Laparoscopic • Second most frequently performedbariatric procedure • Mean excess weight loss at 1 yearof 42%1 • Requires implanted medical device • Lowest rate of complications • Buchwald, H. et al., JAMA. 2004; 292:1724-37.
What are the risks and complications of the Adjustable Gastric Band • Migration of implant (band erosion, band slippage, port displacement) • Tubing-related complications (port disconnection, tubing kinking) • Band leak • Port-site infection • Esophageal spasm • Gastroesophageal reflux disease (GERD) • Inflammation of the esophagus or stomach
Vertical Sleeve Gastrectomy Laparoscopic May be an option for carefullyselected patients, including high-risk or super-super-obese patients1. Mean excess weight loss at 1 yearof 59%2 No implanted medical device • ASMBS, Position Statement on Sleeve Gastrectomy as a Bariatric Procedure. June 17, 2007. • Lee CM, et al.
