Current Techniques for the Endoscopic Management of Zenker’s Diverticulum

Procedure characteristic Conventional technique Double incision and snare resection32,33 Z-POEM/STESD41,42
Procedure duration (min) 14–68 28–56 13.8–52.4
Success (%) 60–100 96–100 92–95
Advantages Largest data on outcomes, technically not demanding, major adverse events, short procedure duration, uncommon, recurrences can be treated with same technique High success rate, low recurrence rate, no special accessory required Essentially similar to POEM, good efficacy, low rate of adverse events, complete division of septum can be achieved
Drawbacks High recurrence after single treatment, technique not standardized Difficult in shallow/small diverticulum, limited data (only two studies), long term results remain to be seen Limited data, technical difficulty if not performing submucosal endoscopy, pouch mucosa not cut which may lead to recurrences, no comparative studies

Z-POEM, Zenker’s per-oral endoscopic myotomy; STESD, submucosal tunneling endoscopic submucosal dissection.
