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. ⋯ Although early recurrence can occur, topical GTN ointment is effective in healing chronic anal fissures in children.
