Treatment of Zenker's diverticulum with the help of a plastic hood attached to the endoscope

Endoscopic treatment of Zenker’s diverticulum involves cutting the bridge (cricopharyngeal muscle) between esophageal lumen and diverticular pouch with a rigid or flexible endoscope and one of several different sources of energy (electrosurgery, argon plasma coagula- tion [APC], CO2 laser, etc.) to ensure free passage of ingested liquids and solids into the esophagus.1 Exposure of the bridge in the endoscopic field is a major factor in the success and safety of this procedure.
