LSG is a restrictive procedure that reduces the size of the stomach and limits food intake at one time. It does not cause decreased absorption of nutrients or bypass your intestines. After eating a small amount of food, you will feel full very quickly and continue to feel full for several hours. In addition to reducing the size of the stomach, Sleeve Gastrectomy may reduce the amount of "hunger hormone" produced by the stomach, which may contribute to weight loss after this procedure.
How Is Sleeve Gastrectomy Performed?
We perform the Sleeve Gastrectomy as a laparoscopic procedure. This involves making five or six small incisions in the abdomen and performing the procedure using a video camera (laparoscope) and long instruments that are placed through these small incisions.
About 75% of the stomach is removed leaving a narrow gastric “tube” or “sleeve”. The LSG takes one to two hours to complete.
What Are The Risks Of Laparoscopic Sleeve Gastrectomy?
There are risks that are common to any laparoscopic procedure such as bleeding, infection, injury to other organs, or the need to convert to an open procedure. There is also a small risk of a leak from the staple line used to divide the stomach. These problems are rare and major complications occur less than 1% of the time.
Overall, the operative risks associated with LSG are slightly higher than those seen with the laparoscopic adjustable band but lower than the risks associated with gastric bypass.
What Are The benefits Of Laparoscopic Sleeve Gastrectomy?
Depending on their pre-operative weight, patients can expect to lose between 40% to 70% of their excess body weight in the first year after surgery.
Many obesity-related comorbidities improve or resolve after bariatric surgery. Diabetes, hypertension, obstructive sleep apnea and abnormal cholesterol levels are improved or cured in more than 75% of patients undergoing LSG.
You should discuss all of the available surgical procedures with your surgeon and determine which procedure is best for you.
