How is Sleeve Gastrectomy Performed?
Similar to gastric bypass, sleeve gastrectomy (gastric sleeve) is a surgical procedure that requires general anesthesia. It may also be performed as a an open or laparoscopic procedure. It is typically not considered to be reversible.
With this procedure, approximately 85% of the stomach is removed using a stapling device. This leaves a sleeve type configuration, very similar to the shape of a small banana, within the stomach. There is no change in the anatomy between the stomach and the small intestine
This type of surgery restricts the amount of food that is consumed. People undergoing the surgery typically can expect 50% of excess fat to be lost within 6 to 12 months of the surgery.
