title: [Endoscopic treatment of a Zenker diverticulum. 50 cases].
abstract: OBJECTIVE
  Endoscopy has been used for many years as an alternative to surgery for the treatment of Zenker's diverticulum. We report our experience 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. All patients had contraindications for conventional surgery or deep anesthesia. The surgical technique of endoscopic treatment is performed under general anesthesia using a specially designed endoscope for exposure. Scissors, then after 1990, CO2 LASER, was used to divide 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 necessary to perform two sessions for diverticula larger than 3 cm.
  
  
  CONCLUSIONS
  This safe and efficient treatment can be recommended for patients of all ages with a contraindication for conventional surgery.
