Gastric Sleeve (Sleeve Gastrectomy)

In Sleeve Gastrectomy, the stomach is divided lengthwise and a narrow, banana-shaped tube (sleeve) is created by removing 80% or more of the stomach. The gastric tube is much smaller than the stomach’s natural size, thus restricting the amount of food that can be eaten at a given time. The remainder of the stomach is removed and, since no bypass is created, absorption of nutrients remains normal. The procedure takes about 30 minutes and has been reported to produce a loss of 50% or more of excess weight.

Advantages of sleeve gastrectomy surgery:

Advantages include:

Reduced stomach volume increases the feeling of fullness

Decrease in appetite for the first year after surgery

Normal stomach function allowing most foods to be eaten, just in smaller amounts

Simpler procedure than the gastric bypass surgery

Disadvantages of sleeve gastrectomy surgery:

The potential is higher for inadequate weight loss or weight regain compared to intestinal bypass surgeries


Long term results have not been evaluated


Although every effort is made to educate you on sleeve gastrectomy surgery, there will be specific information that will be discussed with your surgeon.
