Roux-en-Y Gastric Bypass

Monday, February 08, 2010

The Roux-en-Y gastric bypass procedure involves creating a stomach pouch out of a small portion of the stomach and attaching it directly to the small intestine. It is the most common form of bariatric surgery in the United States. Dr. Edward Hill tells us more about this procedure in todays 60 Second Housecall.

Laparoscopic Roux-en-Y gastric bypass is the most common form of weight loss surgery in the United States. It results in reliable weight loss with acceptable risks and minimal side effects if the patient follows post surgery requirements such as diet, vitamin supplementation and exercise.

The surgery creates a very small upper stomach pouch by transecting the stomach. Part of the small intestine is cut and re-connected to the small stomach pouch to provide an outlet to the rest of the intestines.

The surgery is usually done with laparoscopic instruments through several small incisions.

Initial weight loss occurs because it does not take much food or liquid to fill the new, small pouch. Weight loss of 30 to 90 percent of excess body weight is achievable for many patients. Long-term maintenance of weight loss is very successfulbut does require adherence to a behavioral regimen.

It is important that patients who have had a gastric bypass procedure make a lifelong commitment to make the necessary changes in their diet.
