Abstract
To determine the efficacy of endoscopic electrocauterization for pyriform sinus fistula (PSF) using a flexible Bugbee cautery electrode. From 2009 to 2016, a total of eight patients with acute suppurative thyroiditis or cervical abscess secondary to PSF were retrospectively registered in our study (three males, five females; median age 6.5 years). All patients underwent endoscopic electrocauterization as treatment for PSF. Six of eight patients had no recurrence after the initial endoscopic electrocauterization of PSF. One patient with recurrence developed symptoms 9 days after cauterization and another experienced recurrence after 2 years. Mean follow-up for the eight patients was 50 months (range 5-96 months). No post-operative complication was reported. Endoscopic electrocauterization appears to be a less-invasive, safe, and effective method for the treatment of PSF.
