BACKGROUND
A number of recent studies indicate that anal fissure may be treated by applying glyceryl trinitrate (GTN) ointment. The present study aims to determine the effectiveness and patient acceptability of GTN treatment for patients referred to a consultant surgeon.
METHODS
A prospective study of 65 consecutive patients referred to one surgeon (ALP) over a 12-month period was undertaken. All patients were offered 0.2% GTN ointment to be applied intra-anally four times daily for 4 weeks. Informed consent was obtained and review planned for 4 weeks.
RESULTS
Fourteen patients declined treatment and nine of the 14 (64%) subsequently underwent lateral sphincterotomy. Twelve of the 51 patients (18.5%) who accepted treatment could not complete it due to headache or persisting severe anal pain. Thirty-nine of the 51 patients (77%) were able to complete 4 weeks of treatment. Twenty-two of the 39 reported an improvement in symptoms. A total of 22 patients (43%) who started GTN treatment subsequently underwent lateral sphincterotomy.
CONCLUSIONS
Evidence from the present study suggests that GTN ointment has a place in the management of referred patients with severe and/or chronic anal fissure, but sphincterotomy remains an important treatment option for the majority.
