경부접근법을 통한 Killian-Jamieson게실의 수술적 치료 1예

Pharyngoesophageal diverticula have two major catergories : Zenker’s diverticulum and Killian-Jamieson diverticulum. Zenker’s diverticulum is common than Killian-Jamieson diverticulum and is originated in the posterior wall above the cricopharyngeus muscle called Killian’s dehiscence. Whereas, Killian-Jamieson diverticulum is rare pharyngoesophageal diverticulum which protrudes through a muscular gap of anatomical weak area in the cervical esophagus below the cricopharyngeus muscle. They are usually asymptomatic and hard to diagnose without radiologic evaluation, but symptomatic pharyngoesophageal diverticula should be treated with complete excision. Recently, we experienced a rare case of Killian-Jamieson diverticulum which was treated by open surgical excision and suggest the proper approach to excision of Killian-Jamieson diverticulum for preserving the recurrent laryngeal nerve near lateral side of cervical esophagus.
