Treating anal fistula with the anal fistula plug: case series report of 12 patients.

INTRODUCTION

Recurrent and complex high fistulas remain a surgical challenge. This paper reports our experience with the anal fistula plug in patients with complex fistulas.

METHODS

Data were collected prospectively and analyzed from consecutive patients undergoing insertion of a fistula plug from January 2011 through April 2014 at Hazrat-e-Rasoul Hospital in Tehran. We ensured that sepsis had been eradicated in all patients prior to placement of the plug. During surgery, a conical shaped collagen plug was pulled through the fistula tract.

RESULTS

Twelve patients were included in this case study. All patients had previously undergone failed surgical therapy to cure their fistula and had previously-placed Setons. There were eight males and four females with an average age of 44 who were treated for complex fistulas. At a median time of follow-up of 22.7 months, 10 of the 12 patients had healed (83.3%). One patient developed an abscess that was noted on the sixth postoperative day, and there was one recurrence during follow-up.

CONCLUSIONS

Fistula plugs are effective for the long-term closure of complex anal fistulas. Success of treatment with the fistula plug depends on the eradication of sepsis prior to plug placement.
