Sleeve Gastrectomy

Sleeve gastrectomy – a surgical weight-loss procedure in which the stomach is reduced to about 15% of its original size. The result is a sleeve or tube like structure. The procedure permanently reduces the size of the stomach although there could be some dilatation of the stomach later on in life.

The sleeve gastrectomy procedure can be the first step before other surgical procedures -

  • The surgeon creates a small stomach "sleeve” using a stapling device; the rest of the stomach is removed
  • This induces weight loss in part by restricting the amount of food that can be eaten without bypassing the intestines and therefore absorbed
  • Weight loss and improvement in parameters of metabolic syndrome are connected with the resection of the stomach and subsequent neurohormonal changes
  • If the sleeve gastrectomy is used as the first step before gastric bypass, in the second step the surgeon attaches a section of the small intestine directly to the stomach pouch which allows food to bypass a portion of the small intestine
