Using staples, the stomach is divided into a small pouch above the staples with the remaining stomach (more than 95%) below.

A surgical procedure used to reduce the digestive capacity by shortening the small intestine or shrinking the effective side of the stomach.

See also jejuno-ileostomy. A surgical procedure that limits the amount of food the stomach can hold by closing off part of the stomach. Food intake is restricted by creating a small pouch at the top of the stomach where the food enters from the esophagus. The pouch initially holds about 1 ounce of food and expands to 2-3 ounces with time. The pouch's lower outlet usually has a diameter of about 1/4 inch. The small outlet delays the emptying of food from the pouch and causes a feeling of fullness.
