Dr. Jacques Devière from Brussels performs a Zenker’s diverticulotomy
Dr. Jacques Devière from Brussels performs a Zenker’s diverticulotomy. A special diverticular overtube is used, a plastic tube device with two flaps at the end that is placed into the esophagus. This is preloaded onto the standard gastroscope before the procedure begins. The endoscope is introduced in the usual manner and the overtube is placed into the pharynx with the short flap positioned posteriorly to permit it to enter the diverticulum. When properly positioned, the larger flap is in the esophagus, the shorter one is in the diverticulum, and the septum separating the Zenker’s diverticulum from the esophagus is caught in the "duck-bill" like overtube. This overtube stabilizes the view while the septum is incised with a needle knife using endocut current. Multiple incisions are made with the needle knife until the base of the diverticulum is reached and endoclips are then applied to bring the cut edges together. This usually results in a complete cure of the Zenker’s diverticulum, since the septum between the diverticulum and the main esophageal lumen has been completely destroyed.
