A Case of Zenker’s Diverticulum in a Patient with Tight Esophageal Peptic Stricture

Abstract Zenker’s diverticulum (ZD) is a posterior Sac like outpouching of the hypopharyngeal mucosa and submucosa through Killian’s triangle, which is an area of muscular weakness between the transverse fibers of the cricopharyngeus muscle and the oblique fibers of the lower inferior constrictor muscle. ZD usually presents with swallowing difficulties, regurgitation of undigested food, choking, halitosis, weight loss, and respiratory symptoms due to chronic aspiration. Several esophageal pathologies have been reported in association with ZD. These include cervical esophageal webs, upper esophageal stenosis, and hiatus hernia. Herein, we report a case of ZD in association with severe gastroesophageal reflux disease and tight lower esophageal peptic stricture.
