Argon plasma coagulation for flexible endoscopic Zenker’s diverticulotomy

Abstract

APC treatment of Zenker's diverticulum is safe and effective in the short term, with a mean of three treatment sessions. Recurrence rates of around 15% have to be expected on mid-term follow-up. The relative value of APC vs. needle-knife techniques can only be clarified in a prospective randomized study.
