title: [Endoscopic treatment of Zenker's diverticulum using CO2 laser. 17 cases].
abstract: OBJECTIVE
  Various treatment regimens have been used for the management of Zenker's diverticulum. These include surgery (transcervical diverticulectomy, myotomy) and endoscopic treatment with rigid instruments or flexible endoscope. The aim of this study is to report the results of the treatment of Zenker's diverticulum with rigid endoscope applied CO2 laser and to compare them with other types of treatment.
  
  
  METHODS
  Between May 1991 and November 1996, 17 patients (8 males, 9 females) with symptomatic Zenker's diverticulum underwent endoscopic treatment under short general anesthesia applied CO2 laser. The mean age of the patients was 73.2 years (range: 54 to 97 yrs). All patients had significant symptoms such as dysphagia (15 patients out of 17). All patients were clinically evaluated after the procedure.
  
  
  RESULTS
  The endoscopic incision was performed in one session per patient. Symptoms and dysphagia disappeared in all patients except one (dysphagia). Two complications (one cervical emphysema, one fistula) were managed clinically. Mortality was 0%. Mean follow-up was 17 months. There was no recurrence of dysphagia, all patients remained asymptomatic.
  
  
  CONCLUSIONS
  Rigid endoscopic treatment of symptomatic Zenker's diverticulum applied with laser CO2 is an efficient and safe method. It should be considered as an alternative therapy for Zenker's diverticulum, especially for patients at a high surgical risk.
