Sleeve Gastrectomy



The Sleeve Gastrectomy was created from a Bariatric surgery called the Biliopancreatic Diversion with Duodenal Switch (or just Duodenal Switch). This operation often involved two stages with an initial surgery to remodel the stomach; an intestinal bypass was performed at a later stage. With excellent short-term results, the first stage of stomach remodeling has evolved into its own procedure. The Sleeve Gastrectomy involves remodeling the stomach into a narrow tube. No prosthetic is used to create or maintain the “sleeve.” Once the size and shape of a small football, the stomach becomes similar in shape to a thin banana. Weight loss occurs by two different processes.

By “tubularizing” the stomach, the Sleeve Gastrectomy restricts the amount of food that you may consume at one time. As your stomach responds to stretch, small portions will make you feel full. In addition, removing part of the stomach changes your gut hormones. Ghrelin is an example of a gut hormone that is reduced in your bloodstream by removing the cells that produce it. Ghrelin stimulates appetite; so, removing the cells that produce it is reported to lessen hunger.
