Iatrogenic perforation in endoscopic stapling diverticulotomy for pharyngeal pouches.

In pharyngeal pouch surgery, the relatively new technique of endoscopic stapling diverticulotomy has a number of advantages over more traditional surgical treatments, such as Dohlman's procedure and open pouch excision, and now seems to be the procedure of choice. However, a number of iatrogenic perforations and deaths have been reported with this procedure. We present three cases of iatrogenic perforations occurring during endoscopic stapling of a pharyngeal pouch by different surgeons in our unit, and review the management, causes and prevention of this potentially life-threatening complication.
