Long-term results of endoscopic stapling diverticulotomy for pharyngeal pouches.

Objective: The aim of the present study was to evaluate the long-term success of endoscopic stapling as a primary procedure for the treatment of pharyngeal pouches.

Methods: This study is a retrospective case review of 25 patients with pharyngeal pouches treated by endoscopic stapling (23 stapled, 2 abandoned) over a 4-year period (1994 to 1998) at a University teaching hospital in the United Kingdom. Outcome measures used were relief of symptoms over a long-term follow-up of 2 to 5 years.

Results: Of the 25 patients analyzed, 12 patients (48%) have remained asymptomatic after their initial stapling. Eight patients (32%) were relieved of their symptoms after revision stapling. The overall long-term success rate for endoscopic stapling was 80% (20 of 25 patients)

Conclusion: Reduced morbidity and few complications in the elderly make endoscopic stapling a favored primary technique of treating pharyngeal pouches. Open surgery is recommended only in healthy patients with very large pouches.
