Gastric Band Surgery

About Gastric Band Surgery

Gastric band surgery, which is also called Laparoscopic Adjustable Gastric Banding (LAGB), is a type of weight-loss surgery which reduces the size of stomach by using an inflatable silicone band to create a small gastric pouch in the stomach, so the patient will eat less and feel full faster.


This surgery is advised to the patients who couldn't lose weight non-surgically and diet or exercise wasn’t helpful for them.  Gastric band surgery is not the only solution for surgical wieght loss. Gastric Sleeve, Gastric Pelication, and Gastric Bypass are among other procedures leading to the same result.

How is Gastric Band Surgery performed?

Gastric band surgery is an endoscopic bariatric therapy which means it is done through the use of endoscopy. The procedure is also done under general anesthesia.


The surgeon makes several small incisions in the patient's upper abdomen and then inserts small tools inside the body to reach the stomach. The laparoscope is also inserted so the surgeon can see the operation clearly.


During the surgery, the surgeon tightens an adjustable silicone band around the upper stomach and makes a small stomach pouch. The band is also connected to a device under the skin via a small tube through which a saline solution can be inserted to tighten the band and reduce the size of the stomach further over time.


In the end, the surgeon takes out the tools and sutures the cuts.
