Repair of fistulae in-ano in children using image guided Histoacryl injection after failure of conservative treatment.

PURPOSE: Our aim is to determine the feasibility and safety of N Butyl Cyanoacrylate (HISTOACRYL), adhesive material in the treatment of fistula in-ano in infants and children.

PATIENTS AND

METHODS

30 patients who presented with a perianal fistula (25 males and 5 females) were studied. Their ages ranged from 9 months to 15 years. All patients received medical (conservative) treatment. Six patients improved, 7 patients were subjected to surgical intervention, and the remaining 17 patients were managed by injection of adhesive material through the fistula under fluoroscopic guidance and general anesthesia after failure of medical management.

RESULTS

Of the 17 children who underwent injection therapy to the fistula in-ano after failed medical management, 14 patients were males. The procedure time was 10 to 15 min. The mean follow up was 18 months. Two patients had a recurrence after one to two months. They were subjected to reinjection, and one of them had a second recurrence. Overall, 16 (94%) of 17 patients have had successful closure of their fistula, and one of them healed from a second injection.

CONCLUSION

Our method of tissue adhesive Cyanoacrylate injection is safe, feasible, and can be used repeatedly in treatment of fistula in-ano in infants and children.
