Illustration of a human stomach after gastric band surgery. The upper part of the picture shows the esophagus entering the stomach. The band is around the upper part of the stomach. It's connected to a port (top right) via a cord. The surgeons can laparoscopically implant a band with adjusted wideness after the surgery, by a reservoir filled with fluid. By being implanted right below the cardia, it reduces the fullness of the pouch. The procedure is done for weight reduction. The gastric band reduces the amount of food intake by constringing the passage. The goal is a quickly occuring feeling of satiety.
