ENDOSCOPIC TREATMENT OF ZENKERS-DIVERTICULUM - 50 CASES

OBJECTIVES: Endoscopy has been used for many years as an alternative t o surgery for the treatment of Zenker's diverticulum. We report our ex perience in 50 cases. METHODS: From 1979 to 1995, we treated 50 cases of Zenker's diverticulum endoscopically. Patients' age ranged from 59 to 98 years. Ail patients had contraindications for conventional surge ry or deep anesthesia. The surgical technique of endoscopic treatment is performed under general anesthesia using a specially designed endos cope for exposure. Scissors,then after 1990, CO2 LASER was used to div ide the posterior crico-pharyngeal muscle fibers. RESULTS: There were no major complications. Our results, 95% success, were comparable with those reported in the literature even though, paradoxically, a small diverticulum may remain. Our experience also showed that it may be nec essary to perform two sessions for diverticula larger than 3 cm. CONCL USION: This safe and efficient treatment can be recommended for patien ts of ail ages with a contraindication for conventional surgery. (C) 1 997, Masson, Paris.
