Resection of an Esophageal Diverticulum by Thoracoscopy in Prone Position.

Abstract

Diverticula of the middle one third of the esophagus are rare clinical entities, by comparison with the more common epiphrenic diverticula. For midesophageal diverticula, a minimally invasive approach has not been standardized. This report presents the case of a 60-year-old man with a large midesophageal diverticulum who was treated successfully by four-port video-assisted thoracic surgery while he was in the prone position. Thoracoscopy is a good approach for direct visualization of the diverticulum, and the prone position has several advantages to help clear the view. Routine myotomy for middle one-third diverticula is not advised, given the risk of poor functional results and diverticulization of the myotomy itself.
