What is sleeve gastrectomy?

Sleeve Gastrectomy

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 procedure permanently reduces the size of the stomach. The procedure is performed laparoscopically and is not reversible. The largest benefit of this surgery is that the missing portions of the stomache no longer produce the hormone of Ghrelin.
