Sleeve Gastrectomy
Sleeve gastrectomy is part of the Duodenal Switch operation. It has gained acceptance as a primary weight loss surgical procedure where a restrictive mechanism is thought to be sufficient for adequate and sustained weight loss. With Sleeve Gastrectomy the stomach is reduced in size by 70-85%. This is accomplished by removal of the "greater curvature" (left side) of the stomach. This results in not only a greatly reduced volume of the stomach but also results in reduction of ghrelin, which plays a significant role in appetite regulation and control. Unlike the Gastric Bypass, where the way the stomach and the small bowel interact is changed, in the Sleeve Gastrectomy the only difference is the reduction in the size of the stomach. This avoids all the frequent complications of the Gastric Bypass such as dumping syndrome, marginal ulcers, intolerance of solids, iron deficiency, and weight regain.
When compared to the Adjustable Gastric Banding (Lap Band, Realize band) there are no foreign objects implanted with the Sleeve Gastrectomy, thus there is no risk of infection, and there is no need for continuous adjustments.
