What is Laparoscopic Sleeve Gastrectomy?

The laparoscopic sleeve gastrectomy is a type of bariatric surgery in which a portion of the stomach is surgically removed. The procedure is performed on obese and morbidly obese patients to initiate weight loss and improve overall health, with respect to obesity related co-morbidities such as diabetes, sleep apnea, osteoarthritis, and hypertension.


The procedure: After being put to sleep with a general anesthetic, the procedure is typically performed laparoscopically. Unlike the Lap-Band, the sleeve gastrectomy is a non-reversible procedure. It is termed the ‘sleeve gastrectomy’ due to the sleeve that is formed by surgically stapling the edges of the stomach. After creation of the gastric sleeve, the remainder of the stomach is removed. Reducing the size of the original stomach by up to 85% a small, long pouch is created. Therefore, a person feels fuller after eating a somewhat small amount of food in combination with body metabolism alterations that reduce the craving for food.

Laparoscopic sleeve gastrectomy is a restrictive procedure that reduces the size of the stomach, without altering the gastrointestinal tract. Because of this, nutrients are better absorbed and the patient is less dependent on vitamin supplements.

The length of the procedure varies between two to three hours with a hospital stay of one to two days.

Healthy eating, small portions, and exercise are all lifestyle modifications that will need to be made following the procedure to ensure adequate weight loss results.
