Laparoscopic Sleeve Gastrectomy is part of the Duodenal Switch operation. It has gained acceptance as one of the primary weight loss surgical procedures in which a restrictive mechanism is considered sufficient for adequate and sustained weight loss. When Dr. Ara Keshishian performs the Sleeve Gastrectomy he reduces stomach, which is accomplished by removing the “greater curvature” (left side) of the stomach. This results in not only a greatly reduced volume of the stomach, but also reduces ghrelin, a gastrointestinal hormone that plays a significant role in appetite regulation and control. Unlike the Gastric Bypass, which changes the way the stomach and small bowel interact, the only difference with the Laparoscopic Sleeve Gastrectomy is the reduced size of the stomach. This procedure avoids the frequent complications of the Gastric Bypass, such as dumping syndrome, marginal ulcers, intolerance of solids, iron deficiency, and weight regain.


Unlike Adjustable Gastric Banding (Lap Band, Realize band), there are no foreign objects implanted with the Laparoscopic Sleeve Gastrectomy, which means there is no risk of infection and no need for continuous adjustments.

Dr. Keshishian in proficient in minimally invasive surgical techniques and we offer several options for Sleeve Gastectomy.
