During the gastric band procedure, surgeons usually use laparoscopic techniques (which uses small incisions and long-shafted instruments), to implant an inflatable silicone band into the patient's abdomen. Like a wristwatch, the band is fastened around the upper stomach to create a new, tiny stomach pouch that limits and controls the amount of food you eat. It also creates a small outlet that slows the emptying process into the stomach and intestines. As a result, patients experience an earlier sensation of fullness, are satisfied with smaller amounts of food and, in turn, lose weight.

Since there is no cutting, stapling or stomach re-routing involved in the LAP-BAND System procedure, it is considered the least traumatic of all weight loss surgeries. The laparoscopic approach to the surgery also offers the advantages of reduced post-operative pain, shortened hospital stay and quicker recovery. And, if for any reason the LAP-BAND System needs to be removed, the stomach generally returns to its original form.

The LAP-BAND System is also the only adjustable weight loss surgery. The diameter of the band is easily modified for a customized weight-loss rate as your individual needs can change as you lose weight. For example, pregnant patients can expand their band to accommodate a growing fetus, while patients who aren't experiencing significant weight loss can have their bands tightened.

To modify the size of the band, its inner surface can be inflated or deflated with a saline solution. The band is connected by tubing to an access port, which is placed well below the skin during surgery. After the operation, the surgeon can control the amount of saline in the band by entering the port with a fine needle through the skin.
