Devices and techniques for flexible endoscopic management of Zenker’s diverticulum (with videos)

Abstract

Background and Aims: Zenker's diverticulum (ZD) has traditionally been treated with open surgery or rigid endoscopy. With the advances in endoscopy, alternative flexible endoscopic treatments have been developed.Methods: This document reviews current endoscopic techniques and devices used to treat ZD. Results:The endoscopic techniques may be categorized as the traditional flexible endoscopic septal division and the more recent submucosal tunneling endoscopic septum division, also known as peroral endoscopic myotomy for ZD. This document also addresses clinical outcomes, safety, and financial considerations.Conclusions: Flexible endoscopic approaches treat symptomatic ZD with results that are favorable compared with traditional open surgical or rigid endoscopic alternatives.
