Distinguished as an American Society for Bariatric Surgery  (ASBS) Center of Excellence, the Mount Sinai Program for Surgical Weight Loss has extensive experience performing the latest techniques in minimally invasive weight-loss surgery.

Gastric bypass
The most common weight loss operation performed in the United States, gastric bypass creates a small stomach pouch and bypasses three to five feet of intestine. Patients typically lose 50 to 75 percent of their excess weight as a result of this procedure.

Adjustable gastric banding
For this procedure, the surgeon wraps a small adjustable band around the upper stomach, creating a small stomach pouch that fills quickly. Injecting saline solution into a small access port under the skin adjusts the amount of restriction. After receiving this surgery, patients usually lose 40 to 60 percent or more of their excess weight.

Sleeve gastrectomy
This operation removes the left side of the stomach. The procedure creates a new stomach that is roughly the size and shape of a banana. The operation does not involve any intestinal “rerouting” or reconnecting. Patients typically lose 80 to 100 pounds.

For patients with a body mass index greater than 60, the sleeve gastrectomy may be the first part of a two-stage operation that also includes the biliopancreatic diversion with duodenal switch (BPD-DS).

Biliopancreatic diversion with duodenal switch (BPD-DS)
This procedure reduces the stomach to roughly the size and shape of a banana. Then, a large amount of small intestine is bypassed. This operation results in less restriction than the gastric bypass, but more malabsorption. This more complex operation can produce a weight loss of 60 to 80 percent of excess weight.

Bariatric surgery provides excellent results for most patients. But some patients may not have had the positive outcome they expected, especially if they had older procedures performed. If you have had a prior bariatric operation but have not achieved successful weight loss, you may be a candidate for a revisional operation.

Many patients choose plastic surgery to remove excess skin after they achieve their target weight. The Mount Sinai Division of Plastic and Reconstructive Surgery has special expertise in a procedure called belt lipectomy, which was created for weight-loss surgery patients.
