AIM: Spasm of the internal anal sphincter plays a role in haemorrhoidal disease and may be a source of anal pain after haemorrhoid surgery. In this study, we investigated the effect of topical diltiazem (DTZ) on postoperative pain following Milligan-Morgan haemorrhoidectomy. METHOD: After haemorrhoidectomy, 33 patients were randomly assigned to receive DTZ ointment (2%; n = 16) or a placebo ointment (n = 17). Ointments were applied to the perianal region three times daily for 7 days. A Visual Analogue Scale was used to assess postoperative pain. The primary end-point was reduction in postoperative pain. RESULTS: Patients using the DTZ cream had significantly less pain and greater benefit than those in the placebo group throughout the first postoperative week, and total and daily narcotic analgesic use was higher in the placebo group. There were no differences in morbidity between the two groups. CONCLUSION: Perianal application of DTZ cream after haemorrhoidectomy significantly reduces postoperative pain and is perceived as beneficial, with no increase in associated morbidity.
