In this operation a small stomach pouch is created to restrict food intake. Next,
the small intestine is reconfigured and attached to the pouch to allow food to
bypass the lower stomach,the duodenum (the first segment of the small intestine) and the
first portion of the jejunum (the second segment of the small intestine).
This bypass reduces the absorption of food and thereby reduces
the calorie intake.
