Sleeve Gastrectomy Procedure

Sleeve gastrectomy is a surgical weight-loss procedure in which the stomach is reduced to about 25% of its original size by surgical removal of a large portion of the stomach, following the major curve. The open edges are then attached together (often with surgical staples) to form a sleeve or tube with a banana shape.

The stomach, which is normally shaped like a kidney bean, is stapled off to create a smaller tube or "sleeve", and the remaining stomach is removed.

The procedure permanently reduces the size of the stomach. The procedure is performed laparoscopically and is not reversible.

  • The surgeon creates a smaller stomach pouch to produce restriction but without affecting the food's normal transit through the stomach and small intestine.
  • The surgery is done laproscopically through several small incisions.

Unlike the gastric bypass procedure, there is no re-routing of the small intestine, resulting in lower malabsorption and nutritional deficiency risk. The resulting weight loss is primarily due to limiting the amount of food that can be consumed (restriction).

As with all bariatric procedures, the sleeve gastrectomy is a "tool" and success is dependent on adherence to diet, exercise, support and counseling to achieve maximum results.
