Postoperative pain at 12 hours after surgery and on postoperative days (PODs) 1, 2, 7, 14 and 28 was evaluated by Visual Analog Scale (VAS). Pain on defecation on PODs 1, 2, 7, 14 and 28 was also recorded using the VAS. The consumption of analgesics was also analyzed.Results: No significant difference was found in baseline characteristics between the two groups. Postoperative pain score of the XZD group was significantly lower on POD 2 (6.04±1.11 vs 6.33±1.14, P=0.0229), POD 7 (3.35±0.75 vs 4.22±0.87, P=0.0000) and POD 14 (2.87±0.64 vs 3.64±0.77, P=0.0000) than that of the control group. Similarly, patients in the XZD group experienced significantly less pain on defecation on POD 2 (5.02±1.34 vs 5.43±1.56, P=0.0130), POD 7 (3.08±1.17 vs 3.52±1.29, P=0.0017) and POD 14 (2.31±0.85 vs 2.68±0.99, P=0.0004). Patients in the XZD group consumed significantly less analgesic medication on POD 2 (P=0.0136), POD 7 (P=0.0074) and POD 14 (P=0.0046) than the control group. Conclusion: XZD could effectively relieve postoperative pain and reduce analgesic medication consumption after hemorrhoidectomy.
