Abstract

Introduction

Post-hemorrhoidectomy pain is significantly associated with a hypertonicity of the internal anal sphincter. We evaluated the effects of topical diltiazem, a calcium channel blocker, in reducing pain after hemorrhoidectomy. Purpose of our study was to determine difference in extent of pain control by application of topical calcium channel blocker (diltiazem 2%) versus placebo ointment.

Methods

This was a prospective randomized double-blind clinical study conducted at Sawai Man Singh Hospital, Jaipur, from May 2016 to May 2017. Sixty patients, who had undergone hemorrhoid, were randomly assigned to receive 2% diltiazem ointment (n = 30) or a placebo ointment (n = 30) postoperatively. Ointments were applied to the perianal region three times daily for 7 days. Pain scores were recorded using visual analog scale at 6, 24, and 48 h and seventh day postoperatively and number of analgesic doses consumed by patients in the first 3 days.

Results

Patients using the diltiazem ointment had significantly less pain and greater benefit than those in the placebo group throughout the first postoperative week (p < 0.001) except for reading at 6 h. Also, there was significantly less number of analgesic doses consumed in the diltiazem group compared to the placebo group.

Conclusion

Perianal application of 2% diltiazem ointment after hemorrhoidectomy significantly reduces postoperative pain and is perceived as beneficial.
