The purpose of vertical sleeve gastrectomy is to reduce the amount of food that a patient consumes by surgically removing the majority of the stomach. Simply put, there is no room to ingest large quantities of food after the surgery. Vertical...
sleeve gastrectomy falls under the class of bariatric surgeries known as restrictive surgeries meaning that food intake is restricted. This is in contrast to the other main class of bariatric surgeries known as malabsorption surgeries. As the name implies, malabsorption surgeries interfere with the body’s ability to absorb nutrients that are ingested. Of note, mixed bariatric surgeries combine features of restrictive and malabsorption surgeries.

Vertical sleeve gastrectomy is usually reserved for patients with a BMI over 60. This procedure is often used for severely obese patients in whom gastric banding surgery is contraindicated. In patients whose BMI ranged between 35 and 75, vertical sleeve gastrectomy has been shown to be both safe and effective. In one study of vertical sleeve gastrectomy patients whose initial BMI was 61-80, at one year after the surgery the average body weight was cut in half.

Other Information
Sleeve gastrectomy is a surgical weight-loss procedure in which the stomach is reduced to about 15% of its original size, by surgical removal of a large portion of the stomach, following the major curve. The open edges are then attached together (often with surgical staples) to form a sleeve or tube with a banana shape. The procedure permanently reduces the size of the stomach. The procedure is performed laparoscopically and is not reversible.
Sleeve gastrectomy is usually performed on extremely obese patients, with a body mass index of 40 or more, where the risk of performing a gastric bypass or duodenal switch procedure may be too large. A two-stage procedure is performed: the first is a sleeve gastrectomy, and the second is a conversion into a gastric bypass or duodenal switch. Patients usually lose a large quantity of their excess weight after the first sleeve gastrectomy procedure alone, but if weight loss ceases the second step is performed.
Other Information
Weight loss usually reaches a maximum between 18 and 24 months after Bariatric Surgery - 2004.
