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

BACKGROUND: 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.
