Abstract
Objective With the advent of minimally invasive surgery, incisionless surgery, and third-space
endoscopy, the treatment for Zenker's diverticulum has also moved toward less invasive
techniques
Methods New incisionless per oral techniques can be applied for cricopharyngeal myotomy in
Zenker's diverticulum.
Results Five patients underwent Zenker's diverticulum per oral endoscopic myotomy (Z-POEM)
without complications, minimal discomfort, and narcotic consumption, with complete
resolution of their symptoms by history and Eckardt scores.
Conclusions Z-POEM is performed entirely endoscopically with very little associated pain or complication
rates, with short-term follow-up having excellent functional and symptomatic results.
