This image shows a portion of the stomach that was removed during a laparoscopic sleeve Gastronomy, which is a surgical weight loss procedure. Vertical sleeve gastrectomy is surgery to help with weight loss. The surgeon removes a large portion of your stomach. About 75% of the stomach was removed in this case by a resection along the greater curvature, leaving a narrow gastric tube or 'sleeve.' The intestines are not removed or bypassed during this procedure. The new, smaller stomach is about the size of a banana. It limits the amount of food that the patient can eat by allowing the patient to feel full after eating small amounts of food. Tag a friend who is interested in a career as a surgeon! .
