Laparoscopic Sleeve Gastrectomy

Laparoscopic Sleeve Gastrectomy (LSG) is a weight losss procedure also known as Vertical sleeve gastrectomy or gastric sleeve procedure. It is performed on people with obesity.   This is a restrictive procedure.  In this procedure a part of the stomach is removed with the purpose of restricting food intake.  As the size of the stomach is reduced, the patient on eating a small quantity of food feels full and thus the intake of calories is reduced. 

Sleeve gastrectomy also causes decreased appetite. The reason for this is it removes the part of the stomach that is responsible for producing Ghrelin (hunger hormone). 

Sleeve Gastrectomy can be done as a laparoscopic procedure.  In laparoscopy, small incisions called keyhole incisions are made through which thin instruments called laparoscope with a video camera at the tip is inserted into the abdomen.  Sleeve gastrectomy is then conducted with the use of this instrument.  Since Sleeve Gastrectomy can be performed laparoscopically through keyhole incisions, there is no need for a large cut on the abdomen, the recovery time is very less and patient heals quickly.

Advantages of Laparoscopic Sleeve Gastrectomy

  • Surgical risk is lower compared with other weight loss procedures.
  • Weight loss is generally fast.
  • As it is a laparoscopic procedure, the recovery time after surgery is very quick.

Laparoscopic Sleeve Gastrectomy is an established and effective surgical treatment approach for people suffering with Obesity (BMI greater than 30) and type 2 diabetes mellitus who have failed other treatment modalities.

How much weight can a person expect to lose after the procedure?

Patients can lose about 65 to 75% of their excess weight loss, that is weight in excess of the ideal body weight.
