BACKGROUND/AIMS: Late efficacy of medical treatment of chronic anal fissure remains controversial due to high recurrence. This study aimed at analyzing safety and efficacy of topical diltiazem and bethanechol regarding healing and symptoms relief, safety, recurrence, and need for surgery.
METHODOLOGY: This was a single-center nonrandomized trial. Outcomes of 30 patients with chronic anal fissure treated with 2% diltiazem were compared to 30 patients treated with 0.1% bethanechol, both for eight weeks. Patients were assessed after seven days and eight weeks.
RESULTS: In diltiazem group, after seven days, 31% were symptomatic; after bethanechol, 71% (p = 0.06). After seven days, fissure healing occurred in 19% after diltiazem and in 11% after bethanechol. After eight weeks, in both groups, 64% were asymptomatic; after diltiazem, 53% healed; after bethanechol, 50% (p = 0.80). Success was the same for both groups: 63.3%. Groups were similar regarding complications. After diltiazem, 9 (30%) patients were operated on; and 11 (36.7%) after bethanechol (p = 0.60). Recurrence occurred in 4 (13.3%) patients in both groups. Median time to recurrence after diltiazem was 15 (10-24) months and 7.5 (2-15) after bethanechol - p = 0.15.
CONCLUSIONS: Both treatments are safe and effective. Diltiazem may be associated to earlier relief and more sustained response.
