Laparoscopic Gastric Banding

What is a Laparoscopic Gastric Banding?

It is a procedure using a belt-like silicone device to wrap around the proximal part of the stomach in order to restrict the food intake.  It creates a very small gastric reservoir for food and thus makes the patient early satisfy (easy to get full).  It contains a balloon that can be inflated to tighten the wrap, thus this is an adjustable system.

How is it done?

It is done by using a laparoscopic technique.  There will be 5 to 7 small incisions.  The sizes of the incisions were between 0.5 to 3 cm.  The longest incision is for the site of a metal part that will be buried in the subcutaneous plane under the skin. This part is used to fill (or inflate) the balloon.

Why is it done?

It is aimed to restrict the food intake and thus results in significant weight loss.  Persons whose body mass index are above 35 kg/sq.m with comorbid conditions are indicated for this procedure.

Risks & complications

Before surgery, the patient needs to be assessed for his or her surgical risk.    The operation is done under general anesthesia.  Therefore, it harbors same risks as other surgeries.

Long-term complications are usually related to the band itself.  Slippage of the band, prolapsed of the stomach into the band and erosion of the band into the stomach walls are those known complications.  Complication occurs in about 10% according to the literature.


Laparoscopic gastric bypass is a good alternative.  We also offer this procedure to morbidly obese patients.

Candidate eligibility

The best candidates for Laparoscopic Gastric Banding are people whose Body Mass Index (BMI) is over 35 kg/sq.m. with comorbid diseases (e.g., diabetes, hypertension, sleep apnea, etc) and those who are over 40 kg/sq.m. with or without comorbid are eligible to this procedure.

BMI = body weight in kg / (height in meters)2
