A laparoscopic adjustable gastric band is a restrictive device implanted via laparoscopic bariatric surgery and designed for obese patients. It consists of a silicone band with an inflatable inner cuff connected by silicone tubing to an implanted subcutaneous injection port, which is sutured in the anterior rectus sheath. The band is placed around the upper portion of the stomach to create a small upper pouch with a stoma to the remainder of the stomach. The pouch holds approximately 110 to 220 grams of food each meal, which helps the patient feel hungry less often.

Indications include a body mass index of 40 or greater, or between 35–40 in cases of patients with certain comorbidities that are known to improve with weight loss, such as sleep apnea, diabetes, osteoarthritis, GERD, or metabolic syndrome. Some patients who undergo adjustable gastric band surgery lose more than 60% of excess body weight.

Some complications may include slippage of the band or migration of the access port, which may require reoperation. Erosion of the band into the stomach has also been reported.
