Vertical Sleeve Gastrectomy
The Vertical Sleeve Gastrectomy (VSG), like the gastric bypass, generates weight loss by restricting the amount of food that can be eaten.
In a VSG procedure, the stomach is stapled and divided vertically. This removes more than 85 percent of the stomach pouch. The remaining pouch, or sleeve, is about the size of a banana. It allows for normal digestion and absorption. Food consumed passes through the digestive tract in the usual order, which allows it to be fully absorbed into the body.
