The Zenker’s diverticulum is an out pouching of the hypopharynx arising between the fibers of the cricopharyngeus inferiorly and the inferior constrictor superiorly. This region of herniation is known as Killian’s triangle. Patients often present with a longstanding history of gradually increasing dysphagia of both solids and liquids. Regurgitation of undigested food hours after a meal is a classic presentation. In addition, patients often complain of hoarseness, choking episodes, halitosis, and in severe cases, may have significant weight loss to the point of cachexia. Patients may also present with recurrent pneumonia.
