The majority of patients that undergo vertical sleeve gastrectomy achieve a profound weight loss. The average weight loss at one year after surgery is about 50 percent of the person’s measured weight immediately prior to surgery. The range...

of weight loss from vertical sleeve gastrectomy is between 33 and 83 percent of initial weight. Maximum weight loss is seen within 12 to 18 months after surgery. Also within one to two years of surgery, patients and their physicians routinely report resolution of various obesity-related illnesses including high blood pressure, type 2 diabetes mellitus, and obstructive sleep apnea. Various blood cholesterol (LDL, HDL, triglycerides) levels begin to of fully normalize after vertical sleeve gastrectomy. While the procedure is rather new, vertical sleeve gastrectomy appears to be at least as effective and safe as other, more traditional bariatric surgeries.
In cases where the desired weight loss has not been achieved with vertical sleeve gastrectomy alone, the procedure is occasionally followed by a malabsorption surgery such as the duodenal switch procedure. Additional bariatric surgeries need to be thoroughly discussed with the bariatric surgeon in concert with other weight loss specialists to identify the precise cause of treatment failure.

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.
 
For patients that are obese but not extremely obese, sleeve gastrectomy alone is a suitable operation with minimum risks. Some surgeons even prefer it over gastric banding, because it eliminates the need of having to insert a foreign body.The sleeve gastrectomy currently is acceptable weight loss surgery option for obese patients as a single procedure. Most surgeons prefer to use a bougie between 32 - 40 Fr with the procedure and the approximate remaining size of the stomach after the procedure is about 2 ounces.
