An Atypical Zenker's Diverticulum: A Case Report.

A Zenker's diverticulum (ZD) is an acquired hernia of the mucosa and submucosa at the pharyngoesophageal junction dorsally through Killian's triangle, considered a zone of weakness. The authors report their experience in the management of a case of a ZD with oral externalization following coughing. Surgery made by a multidisciplinary team consisted first of resection of the edematous exteriorized portion of the diverticulum. Second, endoscopic assistance helped to reduce the remaining portion of the diverticulum, and a right anterolateral cervicotomy allowed to remove it at the origin. Immediate and medium-term postoperative follow-ups were uneventful. Functional and endoscopic results were satisfactory. A ZD is a rare condition that can take confusing or even enigmatic forms, making it a real challenge in terms of management.
