Experience and Technique for Zenker's Diverticulum Per Oral Endoscopic Myotomy: Z-POEM.

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.
