Sleeve Gastrectomy

Vertical Sleeve Gastrectomy is a restrictive weight loss procedure in which a large part of the stomach is surgically removed. This results in a new stomach which is roughly the size and shape of a banana.

It is a new weight loss surgical procedure so long-term results (> 5 years) are not available. There is however a growing body of evidence that Sleeve Gastrectomy, at least within 3-5 years of follow-up, provides excellent weight loss outcomes similar to the Adjustable Gastric Banding and Gastric Bypass procedures.

The surgery is done laparoscopically with a short hospital stay. Since this operation does not involve re-routing or reconnecting the intestines, it is a simpler operation than the gastric bypass and does not carry a risk of nutritional deficiencies due to malabsorption. Unlike the LAP-BAND® procedure, the sleeve gastrectomy does not require the implantation of an artificial device inside the abdomen and does not require adjustments.

The Sleeve Gastrectomy is irreversible. It does also carry risks of leak at the staple lines (where the stomach was removed) as well as narrowing or kinking of the long narrow stomach. Some patients with high BMI might need a second stage procedure to enhance weight loss.
