Laparoscopic Gastric Bypass

In gastric bypass surgery a large section of the stomach is stapled leaving a small pouch. Next, a section of the small intestine is attached to the pouch to allow food to bypass the lower stomach and much of the small intestine. The small pouch can accommodate only a few ounces of food at a time, and fewer calories and nutrients are absorbed due to bypassing the stomach and intestine. Thus patients eat less, absorb fewer calories and lose weight. Gastric bypass is typically reserved for patients who are more than 100 pounds overweight.


The most common gastric bypass surgery is a Roux-en-Y gastric bypass.

In a Roux-en-Y gastric bypass, the stomach is made smaller by creating a small pouch at the top of the stomach using surgical staples or a plastic band. The smaller stomach is connected directly to the middle portion of the small intestine (jejunum), bypassing the rest of the stomach and the upper portion of the small intestine (duodenum).

This procedure can be done by making a large incision in the abdomen (an open procedure) or by making a small incision and using small instruments and a camera to guide the surgery (laparoscopic approach).
