PURPOSE: To compare the healing properties of lateral internal sphincterotomy (LIS) and isosorbide dinitrate (ISDN) ointment for chronic anal fissure.
METHODS: Patients with a chronic anal fissure were randomly assigned to a group treated with ISDN ointment (n = 105) or a group treated with LIS (n = 102). The same investigators examined the patients in a blinded manner, 1, 2, 3, 6, and 12 months after the treatments.
RESULTS: The anal fissure had healed completely by 4 weeks in 64.7 versus 92.2 %, and by 6 months in 77.1 versus 97.1 % of the ISDN and LIS group patients, respectively. At 12 months, the recurrence rates were 4.8 versus 1 % for the ISDN and LIS groups, respectively, and the success rates of the treatments were 72.4 versus 96.1 %, respectively. Six patients in the LIS group experienced minor fecal incontinence, and seven (6.7 %) patients in the ISDN group experienced headaches that responded well to paracetamol.
CONCLUSION: ISDN ointment was reported by all patients to be easy to use. Although its success rate was lower than that of surgery, ISDN can be offered to selected patients with a chronic anal fissure, as it has a low recurrence rate and rare side effects are rare.
