Gastric Sleeve

The gastric sleeve, also called the vertical sleeve gastrectomy, or just the "sleeve," is an additional weight loss surgery option. Weight loss is better with the bypass than the sleeve, and the bypass more reliably resolves diabetes. 

With the gastric sleeve, most of the stomach is removed, leaving just a thin "tube" of stomach to hold the food eaten at a meal. The tube-shaped stomach is sealed closed with staples. The tube functions just like a pouch. It allows patients to feel extremely satisfied with the small amount of food that it takes to fill it, and therefore they tend to eat much less than before surgery.
