Sleeve Gastrectomy

Sleeve Gastrectomy

Sleeve gastrectomy is a surgical weight-loss procedure in which the stomach is reduced to about 80% 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

Sleeve gastrectomy was originally performed as a modification to another bariatric procedure, the duodenal switch, and then later as the first part of a two-stage gastric bypass operation on extremely obese patients for whom the risk of performing gastric bypass surgery was deemed too large. The initial weight loss in these patients was so successful it began to be investigated as a stand-alone procedure.

Sleeve gastrectomy is the most commonly performed bariatric surgery worldwide. In many cases, sleeve gastrectomy is as effective as gastric bypass surgery, including improvements in glucose homeostasis before substantial weight loss has occurred. This weight-loss independent benefit is related to the decrease in gastric volume, changes in gut peptides, and expression of genes involved in glucose absorption.

The procedure involves a longitudinal resection of the stomach starting from the antrum at the point 5–6 cm from the pylorus and finishing at the fundus close to the cardia.The remaining gastric sleeve is calibrated with a bougie. Most surgeons prefer to use a bougie between 36-40 Fr with the procedure and the ideal approximate remaining size of the stomach after the procedure is about 150 mL.
