In this procedure, a large portion of the stomach is surgically removed. The part that is removed is called the "greater curvature", which is the left part of the stomach. This type of resection is commonly called a "sleeve resection" or a "sleeve gastrectomy". The stomach goes from being quart-sized and football-shaped to being about the size and shape of a banana. The part of the stomach where food exits, the pylorus, remains intact. This means that the dumping syndrome typically does not occur after this type of surgery. The size of the stomach is quite reduced, but not nearly as severely as in the gastric bypass procedure. Typically, the remaining stomach is between 100 and 150 ml in volume.
