Changes in impedance planimetry metrics predict clinical response to flexible endoscopy in Zenkerʼs diverticulotomy

摘要

Background and study aims Various techniques have been described for flexible endoscopic therapy for Zenkerʼs diverticulum (ZD). Objective methods to assess myotomy effectiveness are lacking. We assessed the utility of impedance planimetry in flexible endoscopic ZD therapies and correlation with a validated symptom score.
