Pharyngoesophageal diverticulum is a well-known disease entity but is seldomly reported in Korean literature. Recently the authors experienced two cases of pharyngoesophageal diverticulum. A 46 year old female and a 51 year old female patients were admitted due to foreign body sensation in esophagus and dysphagia. Preoperative esophagography and esophagoscopy confirmed the diagnosis of pharyngoesophageal diverticulum in each patient. The authors performed one-stage pharyngoesophageal diverticulectomy and myotomy. Postoperative esophagography revealed no diverticulum or stenosis and symptoms were markedly relieved.
