Third-Space Approach Vs Flexible Endoscopic Septotomy For The Treatment Of Short-Septum Zenker’s Diverticulum

Aims Flexible endoscopic septotomy (FES) has been reported as a safe and effective treatment for Zenker’s diverticulum (ZD). However, patients with short septum (ss;≤20mm) ZD still represent a difficult-to-treat subgroup of patients because of the anatomical limitation leading to reduced operating space for both rigid and flexible endoscopic treatments. Recently, third space tunneling approaches, namely Z-POEM and POES,have been developed to...
