Abstract

Background: Although complete excision is the standard treatment for pyriform sinus fistula (PSF), it has recently been suggested that chemocauterization via the internal orifice of the fistula could be an effective non-invasive treatment for the condition. The present report describes the details of our experience with and the efficacy of endoscopic chemocauterization for pediatric PSF. Method: Between January 2010 and June 2015, four patients were diagnosed with PSF and scheduled to undergo endoscopic chemocauterization. Under general anesthesia, trichloroacetic acid (TCA) solution was endoscopically injected through the opening of the fistula using a fine plastic tube. Esophagogram was obtained at 3 weeks after the procedure to search for recurrence. Complete closure of the fistula was confirmed on endoscopy at 2–3 months after chemocauterization. Results: Two of the four patients were treated once, and the remaining patients required further chemocauterization procedures. No recurrence developed in any patient after it had been confirmed that the fistula's internal orifice had been obliterated. Some transient complications, such as sore throat, nausea or temporary vocal fold paresis, occurred. Conclusion: Chemocauterization with TCA seems to be a useful first-choice treatment for PSF.
