Abstract


Zenker’s diverticulum is a form of esophageal and pharyngeal obstruction located at the Killian-Laimer triangle. It is relatively common in elderly man (seventh or eighth decade of life), and its pathophysiology is not completely understood, albeit theories regarding dysfunction of the upper esophageal sphincter were reported. The main symptoms are dysphagia and odynophagia, but it can complicate to aspiration and perforation of the pharyngeal pouch; also, it can be asymptomatic. Diagnosis is provided through a barium esophagogram. Treatment can be performed through endoscopic surgery, diverticulopexy and myotomy of the cricopharyngeus muscle, although there is no consensus among surgeons regarding the treatment of choice. We report a case of pharyngeal obstruction due to Zenker’s diverticulum which caused massive weight loss in a 76-year-old male.
