Simultaneously occurring Zenker's diverticulum and Killian–Jamieson diverticulum: case report and literature review

Abstract

AbstractBackground:Pharyngoesophageal diverticula have many subtypes, with Zenker's diverticulum being the most common. First described in 1983, a Killian–Jamieson diverticulum is an outpouching in the anterolateral wall at the pharyngoesophageal junction. This is located inferiorly to the cricopharyngeus muscle, unlike Zenker's diverticula which occur superiorly. Killian–Jamieson diverticula are rare and are commonly misdiagnosed as Zenker's diverticula. Less than 30 reports of Killian–Jamieson diverticula have been described in the literature.Case report:A 69-year-old man presented with a 2-year symptomatic history, and was found to have simultaneous Zenker's diverticulum and Killian–Jamieson diverticulum. He was treated successfully with open surgical excision of both pouches.Conclusion:Zenker's diverticulum and Killian–Jamieson diverticulum are diagnosed using radiological studies and endoscopy. Their differentiation is important, as surgical management differs. This paper reviews the literature on Killian–Jamieson diverticula and the management options available.
