Abstract:
Zenker diverticulum (ZD) is the most common hypopharyngeal diverticulum seen often in septuagenarian and octogenarian males. Oropharyngeal dysphagia is the most common presenting symptom. Treatment of ZD has been advancing with the introduction of a wide variety of accessory devices, primarily focusing on obliteration of the septum by complete transection of the cricopharyngeus muscle to recreate the common cavity and restore normal pharyngo-esophageal bolus outflow. This review aimed to provide an overview of the various surgical and endoscopic treatment options for ZD, while focusing specifically on Zenker peroral endoscopic myotomy.
