Sleeve gastrectomy (also referred to as Gastric Sleeve) is a relatively new, restrictive weight loss procedure that limits food intake; the surgeon laparoscopically removes approximately 60 percent of the stomach leaving it shaped like a tube or "sleeve".

This procedure requires an overnight stay in the hospital. With the Gastric Sleeve, weight loss is equal to, or sometimes better than, the Lap-Band® System. Unlike the restrictive banding procedure, no adjustment is needed, and no foreign body is placed around the stomach.
