Known as laparoscopic gastric reduction surgery, also known as sleeve gastrectomy, gastric reduction surgery works by using a laparoscope to cut out the greater curvature of the stomach vertically, resulting in the formation of a small stomach pouch of about 150 cc, which can hold about 4-5 ounces of food.
