The Laparoscopic Sleeve Gastrectomy (also known as Vertical Gastrectomy) involves removing about 75% of the stomach. This leaves a narrow gastric “sleeve” or tube through which your food passes. No intestines are removed or bypassed in a sleeve gastrectomy.
By reducing the size of your stomach, the food portion you take in is significantly decreased. Sleeve gastrectomy also results in significant appetite suppression for the first few years after surgery.
With the surgery, patients can expect to lose about 50 – 60% of their excess body weight.
