The Zenker's Diverticulum is caused by a malfunction of the superior esophageal sphincter (cricopharyngeal muscle). Traditionally the surgical approach for this problem consisted of lateral cervical incision with the resection of the diverticulum.
With this new tran-oral endoscopic technique the septum between the diverticulum and the esophagus is divided by a stapling device and both lumens are "joined" creating a esophago-diverticulostomy. In addition a myotomy of the cricopharyngeal muscle is performed
