title: Submucosal Abscess of the Esophagus Caused by Piriform Sinus Fistula Treated with Transoral Video Laryngoscopic Surgery.
abstract: Piriform sinus fistula (PSF) is a rare branchial anomaly that causes repetitive acute suppurative thyroiditis or deep neck abscess. The definitive treatment of PSF is open neck surgery. However, such surgery has a cosmetic problem and a high risk of recurrence. Furthermore, identifying the fistula is difficult due to previous repetitive infections. We report a case of esophageal submucosal abscess caused by PSF treated with endoscopic mucosal incision. The patient underwent transoral video laryngoscopic surgery (TOVS), and endoscopy as well as fluoroscopy revealed complete closure of PSF without any complication. TOVS is a novel surgical technique for the definitive treatment of PSF with esophageal submucosal abscess.
