The operation of gastric banding is performed with laparoscopic (keyhole) technique under general anaesthesia. Five small incisions are made in the abdomen where laparoscopic instruments are inserted. The adjustable silicone ring (gastric band) is fitted around the top of the stomach and then clipped into place. A fold of stomach is sewn over the band to reduce the chance of a slippage. The band is connected to a small tube and access reservoir (port) which is used to add or remove fluid from the band. The final step of the operation involves fixing the port to muscle under the skin at one of the incision sites.
