Abstract

Roux-en-Y gastric bypass (RYGB) surgery is more effective than nonsurgical treatments of obesity to sustain long-term weight loss. During the RYGB procedure, the stomach is divided into an upper gastric pouch, which is 15–30 mL in volume, and a lower gastric remnant. The gastric pouch is anastomosed to the jejunum after it has been divided some 30–75 cm distal to the ligament of Treitz; this distal part is brought up as a “Roux limb.” The excluded biliary limb, including the gastric remnant, is connected to the bowel 75–150 cm distal to the gastrojejunostomy.

The outcomes following RYGB vary between patients, and predicting individual outcomes is difficult. In this chapter, each outcome is reviewed individually and the controversies that surround it are discussed.
