Cause and treatment of epiphrenic diverticula

These data support the conclusions that: (1) a primary esophageal motility disorder is the underlying cause of most epiphrenic diverticula; and (2) laparoscopic treatment is successful and should be the method of choice. The diverticular neck can be exposed satisfactorily from the abdomen; a stapler inserted from this angle is better orientated to transect the neck than one inserted through a thoracoscopic approach. Furthermore, the myotomy and fundoplication are much more easily performed from the abdomen than from alternative approaches.
