Sleeve gastrectomy or vertical sleeve gastrectomy, is a surgical weight-loss procedure, typically performed laparoscopically, in which approximately 75 — 85% of the stomach is removed, along the greater curvature, which leaves a cylindrical, or "sleeve"-shaped stomach the size of a banana. Weight loss is affected not only through the reduction of the organ's size, but also by the removal of the portion of it that produces ghrelin, the hormone that stimulates appetite.
