Abstract

The Roux-en-Y gastric bypass (RYGB) surgery helps patients achieve excellent excess weight loss, with subsequent improvement or resolution of co-morbidities. However, up to 20% of all RYGB patients, and 40% of the super morbidly obese, experience significant weight regain. The etiology of weight regain is multifactorial; hence, multidisciplinary management is mandatory. Revision options for failed conservative and medical management include resizing the restrictive component of the bypass or intensifying malabsorption. While improvement of restriction generally has limited efficacy, intensifying malabsorption achieves significant long-term excess weight loss. The optimal surgical option should be personalized, considering eating behavior and psychological issues, surgical anatomy of the bypass, and anesthetic and surgical risks.
