Combination of laparoscopic adjustable gastric banding and gastric bypass: current situation and future prospects -- routine use not advised.

Although bariatric surgery has proven to be the most effective treatment for morbid obesity, most surgical techniques do have failures. In an effort to improve the reliability, several surgeons started to use a combination of a laparoscopic gastric bypass with an adjustable gastric band. Because of concerns regarding a possible negative outcome, an expert meeting was organized to evaluate the current situation and future application. In total, 104 operations were reported,with several technical variations. The overall complication rate was acceptable, but the percentage of the band erosions was 6.7%, which is too high. The potential advantages (adjustability, maintained access to the stomach and biliary tree, and reversibility) do not compensate for this complication rate. Based on the results and the opinion of the surgeons experienced in this technique, it is concluded that the combination of gastric bypass with an adjustable gastric band to form the pouch is not recommended.
