Endoscopic Zenker's diverticulotomy: fewer recurrences due to Z-POEM?

Aims Endoscopic diverticulotomy is nowadays the standard procedure for the treatment of symptomatic Zenker's diverticulum. With Z-POEM (peroral endoscopic myotomy), a new technique is now available that may reduce recurrences. Z-POEM has been used at our center since 2021. We retrospectively evaluated data regarding effectiveness and complication rate compared to conventional diverticulotomy. [1]
