Laparoscopic Sleeve Gastrectomy
Although the gastric sleeve is a restrictive procedure in the United States for its safety, lack of significant complications and steady weight loss. The operation involves removing a large part of the stomach that resembles a long tube (gasatric sleeve). Recent studies show that there is also a metabolic effect significant enough to help diabetic patients. Side effects include gastroesophageal reflux. This is an effective procedure for all patients with exception of those who already suffer with gastroesophageal reflux.
In this procedure, 60-70% of the stomach is removed using a stapling device.
The new stomach resembles a long tube or banana and can hold up to 60 to 100 cc of liquid or food. Although the gastric sleeve is a purely restrictive procedure, the removal of the stomach does affect certain hormones necessary for metabolism, and therefore, produces significant and durable weight loss. The estimated weight loss for this procedure is 40 to 60% of excess weight. The gastric sleeve is also the first part of the Biliopancreatic Diversion with Duodenal Switch (BP-DS) surgery.
