Definition : Implantable plastic devices (i.e., bands) designed to be placed around the upper stomach to reduce food intake in the treatment of morbid obesity. These devices typically consist of an adjustable silicone elastomer band that is usually placed below the esophagogastric junction in an open surgical or, more frequently, laparoscopic procedure; some bands include an inflatable inner shell and a buckle closure connected by tubing to an access port outside the abdominal cavity. The inner diameter of the band may be periodically adjusted by the addition or removal of saline through the access port according to patient needs (i.e., the required rate of weight loss). Remotely (i.e., transcutaneously) adjustable bands that use an external programmer/tester to exchange information and power by means of an implantable antenna coupled to the band are also available. Gastroplasty bands are intended for use as a controllable and reversible method for achieving weight loss in bariatric patients.
