Sleeve Gastrectomy

The Sleeve Gastrectomy procedure involves removing a large portion of the stomach, leaving behind only a “sleeve” of stomach. This small portion restricts the amount of food that a patient can eat and, therefore, leads to significant weight loss. The sleeve gastrectomy is a purely restrictive procedure as it decreases intake without bypassing the intestines or causing any gastrointestinal malabsorption (unlike the Roux-en Y Gastric Bypass). The outlet valve (pylorus) remains intact as to preserve the functions of the stomach while drastically reducing the volume. This is a laparoscopic procedure.
