To evaluate the analgesic efficacy, duration, and safety of CT-guided inferior rectal nerve block (IRNB) for postoperative pain control following hemorrhoidectomy.
Retrospective analysis of 69 patients with grade III or IV mixed hemorrhoids who underwent hemorrhoidectomy between April 2024 and March 2026.
Patients received either bilateral CT-guided IRNB on postoperative day 1 using triamcinolone acetonide, 0.5% bupivacaine, saline, and epinephrine (Group 1, n = 38) or standard analgesia (Group 2, n = 31).
Pain was assessed using the Numerical Rating Scale (NRS) at baseline, days 1–10, 14, and 28 alongside complications and analgesic consumption.
CT-guided IRNB provided significantly improved pain control over the first 2 postoperative weeks compared to standard analgesia (p < 0.05).
A secondary pain rebound occurred in the intervention group on postoperative day 4 (median NRS 4 [IQR 2–5]), before both groups achieved near-complete pain resolution by day 28.
Complication rates did not differ significantly between the nerve block group and the standard analgesia group.
