Bariatric surgery remains the most effective and durable weight loss method available to patients. However, a significant percentage of patients may regain weight resulting in frustration, depression, and return of obesity-related co-morbidities. Revision surgery is the one of the treatment modalities for such weight regained patients. The more you do bariatric surgery, the more you need to prepare for revision surgery.

Obesity remains a significant disease around the world. Bariatric surgery is the most effective treatment to help promote weight loss and management of weight-related comorbidities. However, there are patients who need more than one procedure to manage these issues or they experience side effects. This session will focus on revisional or conversional bariatric surgery and surgical management of chronic complications. Our faculty will offer insights into the management of these complex patients.

Weight regain or inadequate weight loss after gastric bypass represents one of the most challenging problems in revisional bariatric surgery. Pouch and/or stoma reduction has little to offer, except for short-term and minimal results. Operative revision of the gastric pouch is associated with 3-5 times the incidence of leak and other post-operative complications. Separating behavioral and biologic causes for weight regain is difficult and there are no biochemical measurements available to assist in this important differentiation. A subjective, but consistent tool uses the symptoms of the disease, i.e., hunger and satiation as a surrogate for biological food and calorie acquisition as opposed to psychologic eating. Therefore, taking advantage of the increased metabolic response of the distal type 1 bypass can provide a better response and safer revision than working on the pouch.
