During a sleeve gastrectomy, a sleeve-shaped tube is created from a small portion of the stomach and the majority of the stomach is removed. Food passes through the new stomach tube directly into the intestines. Nutrients and calories are absorbed from food normally, but patients feel full sooner and longer.
Sleeve gastrectomy is performed laparoscopically and can be a permanent surgical solution to manage weight. A second operation may be required, however, if significant weight loss is required to improve the patient's health.
