Long-term results of topical glyceryl trinitrate ointment in children with anal fissure

Abstract

Background/Aim: Although topical glyceryl trinitrate ointment (GTN) has become a popular treatment for anal fissure in adults, its use in children is still limited. We aimed to determine the effectiveness and safety of topical GTN in the long-term management of anal fissure in children, which has not yet been reported. Methods: Thirty-one children with anal fissure who received topical 0.2% GTN treatment between 1997 and 1998 were evaluated in 2004. Results: Ten patients had one or more relapses after initial treatment with 0.2% GTN, all within 1 year of first onset of anal fissure. No further recurrences were diagnosed during the 4-year follow-up period. Conclusion: Although early recurrence can occur, topical GTN ointment is effective in healing chronic anal fissures in children. © 2005 The Liverpool School of Tropical Medicine.
