Abstract
OBJECTIVE: Diltiazem is a calcium channel blocker that has shown potential to heal chronic anal fissures. We have prospectively evaluated the treatment of patients with anal fissure with diltiazem gel (SLA Pharma, UK). PATIENTS AND METHODS: All patients with chronic anal fissure from September 1999 to May 2000 were treated topically with 8 mg 2% diltiazem hydrochloride gel (equivalent to 2 cm of gel supplied by SLA Pharma) three times daily. The 23 patients (12 female), median age 45 (range 22-80) years had a 2-36 month (median 6 months) history of fissure. These were associated with a sentinel tag in 9 (39%) patients. RESULTS: The fissure healed in 11 (48%) of 23 patients, including 6 (75%) of 8 patients who previously failed to heal with GTN ointment. There were no recurrences at 3 months and no adverse effects. Of the 12 patients who did not respond to diltiazem, 4 have undergone sphincterotomy. CONCLUSION: Diltiazem gel has a healing rate similar to that observed with GTN ointment but there were no adverse effects, the recurrence rate was lower, and diltiazem was effective in 75% of patients previously treated unsuccessfully with GTN ointment.
