Introduction

Zenkerʼs diverticulum is an acquired herniation of the mucosa posteriorly through Killianʼs space. Treatment options are surgical, rigid endoscopic, or flexible endoscopic techniques. Flexible endoscopic treatment was first described in 1995 [1].

Cricopharyngeal mucomyotomy has a 91 % success rate, with 11 % adverse events (AEs) and 11 % risk of recurrence [2].

Zenkerʼs peroral endoscopic myotomy (Z-POEM) is a recently proposed technique using third space endoscopy to enable a complete division of the septum in order to decrease the risk of recurrence [3]. Complete closure of the tunnel is essential to avoid adverse events.
