Gastric Bypass Revision
Inadequate weight loss after a gastric bypass may be due to a physical problem with the procedure, continued overeating, or a combination of both. If the problem is solely due to improper eating and the patient is able to modify his or her habits, the problem can be rectified without additional surgery. However, if the stomach pouch or the opening between the stomach pouch and intestine have become stretched, or if the stomach pouch has reconnected with the bypassed portion of the stomach (known as a gastro-gastric fistula), surgery is necessary to correct the problem. Bariatric revision surgery may also be indicated if the patient is suffering from either too much or too little malabsorption, in which case the Roux-en-Y may be converted to another type of bariatric adjustment.
