Zenker's diverticulum: advancing beyond the tunnel.

ABSTRACT:

Background and aims

Zenker's diverticulum (ZD) is attributed to a poorly compliant cricopharyngeus muscle, and the mainstay of treatment is a cricopharyngeal myotomy. We present a video series summarizing endoscopic treatment options for ZD and related conditions.

Methods

We review the rationale and key technique for various endoscopic treatment modalities for ZD, cricopharyngeal bar, and other esophageal diverticula.

Results

Standard flexible endoscopic cricopharyngeal myotomy involves the division of the common wall or septum of the ZD, aiming for complete transection of the cricopharyngeus. However, recurrence rates are high, likely owing to incomplete myotomy. Zenker's peroral endoscopic myotomy (Z-POEM) uses a proximal submucosal tunnel to provide direct visualiz
