Laparoscopic Sleeve Gastrectomy

The principle of this surgery is to fashion the stomach into a tube-like structure in which the stomach is reduced to around 25% of its original size. Weight loss is achieved by decreasing the amount of food intake and satiety. The excess weight loss at 2 years would be around 60 percent. Patients who undergo the laparoscopic sleeve gastrectomy does not require long term mineral and vitamin supplements and the operative risk is lower than the laparoscopic gastric bypass or duodenal switch. The main disadvantage of the operation is its irreversibility with a leakage rate of around 1%.
