Mucosa-preserving Zenker’s diverticulotomy

Abstract

Zenker’s diverticulum (ZD) is a rare condition, with prevalence ranging between 0.01% to 0.11%.1 The mainstay of treatment is cricopharyngeal myotomy. Recently, flexible endoscopic cricopharyngeal myotomy (FECM) (Fig. 1) has become increasingly popular as a safe and effective alternative to open surgery and the rigid endoscopic approach. However, reported recurrence rates range from 0% to 32%,2 likely owing to a lack of procedure standardization and difficulty in performing adequate myotomy for fear of perforation, given the absence of mucosa preservation.
