Gastrocolic ligament

Gastric Sleeve or Sleeve Gastrectomy is a surgical weight-loss procedure in which the stomach is reduced to about 15% of its original size, by surgical removal of a large portion of the stomach along the greater curvature. 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 procedure is generally performed laparoscopically and is irreversible.

Procedure[edit | edit source]

The Sleeve Gastrectomy procedure involves removing approximately 80% of the stomach. The remaining stomach is a tubular pouch that resembles a banana. This procedure works by several mechanisms. First, the new stomach pouch holds a considerably smaller volume than the normal stomach and helps to significantly reduce the amount of food (and thus calories) that can be consumed. The greater impact, however, seems to be the effect the surgery has on gut hormones that impact a number of factors including hunger, satiety, and blood sugar control.

Risks and Complications[edit | edit source]

Like any major surgery, Sleeve Gastrectomy has potential risks and complications. These can include infection, bleeding, blood clots, and reactions to anesthesia. Longer term risks and complications of sleeve gastrectomy surgery can include vitamin and mineral deficiency, gallstones, hernias, and stomach perforation.

Effectiveness[edit | edit source]

Studies have shown that after the Sleeve Gastrectomy procedure, patients can expect to lose 50% to 80% of their excess body weight over a 6 – 12 month period. This weight loss can result in significant health improvements, including lower blood pressure, improved cholesterol levels, and better control of diabetes.
