The laparoscopic adjustable gastric band, better known as the lap band, is a branch of weight-loss surgeries, aiming to treat obesity, when other easier weight-loss methods have failed. The lap band consists of a silicone device, that via laparoscopic surgery is positioned around the upper part of the stomach, helping the patient to cope with the obesity by reducing excess body fat. According to a research conducted in the US, the adjustable gastric band showed some improvements in patients with extra-weight – 80% weight-loss efficiency in some cases.
