Complications of Roux-en-Y gastric bypass and sleeve gastrectomy

Abstract

Roux-en-Y gastric bypass and sleeve gastrectomy are two of the most common bariatric procedures performed in 2011. Although the complication rates associated with these procedures are low, the consequences of these complications are significant and can be associated with high morbidity and mortality. Timely diagnosis and proper management of these complications are extremely important. The most commonly used radiologic studies in bariatric surgery are the upper GI contrast study and the CT scan, which are used to rule out leak, obstruction, perforation, anastomotic stricture, or pouch dilatation. As with all imaging studies, a negative result should not override strong clinical suspicion of a complication.

Laparoscopic sleeve gastrectomy: The rightful gold standard weight loss surgery procedure

“…Herron and Roohipour report similar leak (0-6% to 0.9%) and bleeding rates between RYGB and SG (19) . However, intestinal obstructions are reported in 1.5-5% of RYGB (19) .…”

“…Herron and Roohipour report similar leak (0-6% to 0.9%) and bleeding rates between RYGB and SG (19) . However, intestinal obstructions are reported in 1.5-5% of RYGB (19) . These are often due to internal herniation through the retrocolic or mesocolonic defect or at the jejunojejunostomy site and can lead to intestinal ischemia or necrosis.…”

Evaluation of the LigaSure™ Vessel Sealing System for bowel transection and intestinal anastomosis—an experimental study in a porcine model

“…In contrast, the S anastomosis has higher expenses due to the price of the cartridges. In both methods, the anastomotic leakage rates range between 3 and 6.4 % for colonic anastomosis and jejunojejunostomy in Roux-Y gastric bypass surgery [6][7][8][9].…”

“…13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34 The most promising, currently licensed for use in much of Europe and Latin America, is the BioEnteric Intragastric Balloon, also called the BIB system. It is licensed overseas for short-term use (6 months) and it consists of an intragastric balloon that is placed and removed endoscopically, similar to the Garren balloon used decades ago.…”

“…The most popular, and in fact, the current gold standard for bariatric surgery is the Roux-en-Y gastric bypass 28, 29, 30, 31, 32, 33, 34 (Figure 1). These procedures are done in almost all cases laparoscopically and they have combined restrictive and malabsorptive components.…”
