Mini gastric bypass procedure
This operation is a combination of gastric sleeve surgery and bypass surgery. The top of the stomach divides to a thin tube (30ml to 50 ml in size) by the staple. This thin tube becomes the new and smaller stomach which is completely separate to the rest of the stomach. Then this new stomach is sewn to a loop of the small intestine, bypassing the first part of the intestine called the duodenum and about 150-200cm of the bowel. Although the rest of the stomach and upper part of the small intestine are still remaining in the body but will not be longer used for food digestion.
