Laparoscopic Sleeve Gastrectomy

Laparoscopic Sleeve Gastrectomy

Sleeve gastrectomy is a procedure that induces weight loss by restricting food intake. The sleeve gastrectomy is an operation in which the left side of the stomach is surgically removed.


This results in a stomach, which is roughly the size and shape of a banana or Sleeve. Since this operation does not involve any “rerouting” or reconnecting of the intestines, it is a simpler operation than the gastric bypass or the duodenal switch.

This procedure is usually performed as single stage surgery for >33 BMI patients with co-morbidities or >37 BMI without co-morbidities. Sleeve gastrectomy is also done on super obese or high-risk patients with the intention of performing another surgery at a later time.

Surgical time : 1 Hour
Hospitalisation period : Usually 24 – 48 hours

Advantages of the Sleeve Gastrectomy:

  • It does not require disconnecting or reconnecting the intestines
  • It is a technically simpler operation than the gastric bypass or the duodenal switch
  • It is known to reduce hunger by removal of hunger stimulating hormone producing part of stomach
  • Unlike gastric bypass & gastric band, patients feels full with liquids as well.
