Successful Treatment of Piriform Sinus Fistula

Abstract

Repeated infection in the neck is frequently observed in patients with piriform sinus fistula. Two patients with recurrent piriform sinus fistula and a previous history of surgical treatment presented at our clinic.
Contrast esophagography showed a piriform sinus fistula in both cases. To visualize the fistula, a liquid dye was injected the day before surgery. The fistula was removed under general anesthesia via 2 approaches, each using an external incision and direct esophagoscopy. A 5-day fast was prescribed after surgery. Postoperative esophagography showed a complete closure of the fistula. No recurrences were noted after the surgery.
