Laparoscopic Sleeve Gastrectomy: What to Expect?

How Is Sleeve Gastrectomy Performed? 

The laparoscopic sleeve gastrectomy is a surgical weight loss procedure performed to reduce the stomach size by about 25% of its original size. This procedure will reduce the stomach size permanently and this an irreversible procedure.

During this procedure, your surgeon will make a longitudinal resection of the stomach beginning from the antrum at the point 5 to 6 cm from the pylorus and ending at the fundus closer to the cardia. This results in a tube or sleeve like structure which is calibrated with a bougie. Often the surgeons prefer using a bougie of 36-40 Fr with this procedure. The ideal remaining size of the stomach post sleeve gastrectomy is nearly 150mL.

In this procedure, the doctor will make five or six small incisions in the abdomen and then insert a video camera called laparoscope through these incisions. LSG (Laparoscopic Sleeve Gastrectomy) takes nearly one to two hours to complete.

How Much Weight-loss Occurs after LSG?
