While generally successful, the two most widely-performed surgical procedures, gastric bypass and adjustable gastric banding, require occasional revision. This is due to either device-related problems or unsatisfactory weight loss. In addition, several surgeries that are no longer commonly performed (jejunoileal bypass or the stapled gastroplasty), are associated with many anatomic and nutritional complications. Patients who underwent these procedures frequently require revisional surgery. The outcome of most revisional operations is favorable when performed by an experienced bariatric surgeon—and when patients are appropriately selected for such procedures. The founder of the Khalili Center, Dr. Theodore M. Khalili, is one of the leading authorities on revisional bariatric surgery in the U.S., and has performed more of these procedures than any other doctor in Southern California.
