Objective: To observe the effect of Ruiyun procedure for hemorrhoids (RPH) combined with Milligan-Morgan hemorrhoidectomy with dentate line-sparing on postoperative recovery in patients with mixed hemorrhoids. Methods: Sixty patients with mixed hemorrhoids admitted to Nanfeng County People"s Hospital from July 2024 to October 2025 were selected. They were divided into the control group (30 cases treated with Milligan-Morgan hemorrhoidectomy) and the observation group (30 cases treated with RPH combined with Milligan-Morgan hemorrhoidectomy with dentate line-sparing) using random number table method. Perioperative indicators, anorectal dynamic indexes, and postoperative complications were compared between the two groups. Results: The intraoperative blood loss in the observation group was (18.53±3.81) mL, which was less than that in the control group (23.65±4.62) mL. Postoperative defecation, wound healing, and hospitalization durations were [(1.58±0.51) d (8.01±1.18) d (2.68±0.83) d], shorter than those in the control group [(2.91±0.95) d (10.27±2.55) d (5.42±1.20) d]. The Visual Analog Scale (VAS) score was lower than that in the control group (P<0.05). At 1 month postoperatively, the rectal resting pressure (RRP) and resting anal resting pressure (ARP) in the observation group were (2.16±0.64) kPa and (12.05±1.40) kPa, respectively, lower than those in the control group (2.87±0.97) kPa and (14.23±1.53) kPa. The maximum anal maximal squeeze pressure (AMCP) was (14.03±0.43) kPa, higher than that in the control group (13.85±0.47) kPa (P<0.05). The postoperative complication rate in the observation group (3.33%) was lower than that in the control group (20.00%) (P<0.05). Conclusion: RPH combined with Milligan-Morgan hemorrhoidectomy with dentate line-sparing is conducive to postoperative recovery and can protect anorectal function, with a lower risk of complications.
