Bariatric Surgery Options

No two San Francisco weight loss patients are the same; everyone has his or her specific needs when it comes to bariatric surgery. Because of this, there are several different techniques for performing major weight loss surgery. At my practice, I specialize in the laparoscopic duodenal switch procedure, or the LapDS, which is very effective at helping patients lose weight quickly and keep it off. I also offer the other standard methods for surgical weight loss, including vertical gastrectomy, Roux-en-Y Gastric Bypass, and the LAP-BAND®.

Roux-en-Y Bypass /Gastric Bypass

Roux-en-Y bypass, more frequently referred to as gastric bypass, involves creating a small pouch out of the top part of the stomach and bypassing 15 to 20% of the intestines. This is one of the most commonly performed procedures in the US.

Vertical Gastrectomy

Vertical gastrectomy involves removing the ‘stretchy’ portion of the stomach, and leaving a two to three ounce capacity tube portion of it called a gastric “sleeve.” The intestines are not rerouted in this procedure.


LAP-BAND is a procedure that uses an inflatable silicone band placed around the top of the stomach to restrict a patient’s food intake, resulting in weight loss. This procedure is adjustable and completely reversible.


The laparoscopic duodenal switch surgery makes a more moderate reduction to the stomach volume preserving its normal configuration and emptying mechanism and reroutes the intestines in a more natural configuration than other bypass procedures. This limits the amount of food intake and reduces the absorption of fat and calories.
