A form of obesity surgery that involves restriction (forming a smaller stomach that fills up quickly) and bypassing the early portion of the small intestine (leading to poorer absorption of food calories).
Surgical creation of a small stomach pouch with anastomosis of the stomach with the jejunum, reducing caloric absorption as a treatment for morbid obesity.
Any surgical procedure in which the stomach, or most of the stomach, is isolated and disconnected from the rest of the upper gastrointestinal tract.
