Transoral Endoscopic Diverticulostomy of Zenker’s Diverticulum With Energy Device

Abstract

Zenker’s diverticulum (ZD) is an abnormally protruding space in the Killian triangle due to weakness between the inferior pharyngeal constrictor muscle and cricopharyngeal muscle. A rare disease that is found more often in the West than in the East, it occurs in the elderly, inducing dysphagia, globus symptom, reflux and etc. For the treatment, various transoral endoscopic techniques have been developed over the past 20 years: these include flexible and rigid endoscopy are used and several devices like scissors, staplers, CO<sub>2</sub> laser and energy device. We report here the first case using the endoscopic energy device assisted diverticulostomy of ZD in Korea. Transoral endoscopic treatment is less invasive than classical transcervical approach treatment, showing better clinical course and results. Both rigid endoscope and energy device are also very familiar to head and neck surgeons, so this approach can be one of the best treatments for ZD.
