Endoscopic treatment of the hypopharyngeal (Zenker's) diverticulum

Abstract

Over the years the techniques for endoscopic treatment of Zenker's diverticulum have been improved. Initially, in 1964, we used the electrocoagulation technique as described by Dohlman, but currently we prefer to sever the tissue bridge between the diverticulum and esophagus with the CO2 laser under microscopic control. The results of endoscopic treatment in 507 patients with a diverticulum are discussed. It is concluded that endoscopic treatment can readily be performed with good results, especially in the case of elderly patients in a poor general condition.
