Background

Zenker's diverticulum is an out-pouching of the pharyngeal mucosa and submucosa through the cricopharyngeus muscle. Patients typically present dysphagia, globus sensation, regurgitation of undigested food, and halitosis. Zenker's diverticulum is classified as false diverticulum in that it does not contain all layers of the intestinal wall, but only the mucosa and submucosa.
