Efficacy of Ruiyun procedure for hemorrhoids combined simplified Milligan–Morgan hemorrhoidectomy with dentate line-sparing in treating grade III/IV hemorrhoids: a retrospective study

Abstract

Abstract Background Hemorrhoids are common. Hemorrhoidectomy should typically be offered to patients whose symptoms result from external hemorrhoids or combined internal and external hemorrhoids with prolapse (grades III/IV). However, none of the currently used surgical methods could be considered an ideal surgical option that is effective, safe, and painless. We hypothesized that a combination of Ruiyun procedure for hemorrhoids (RPH) and simplified Milligan–Morgan hemorrhoidectomy (sMMH) will increase the safety and effectiveness of surgical treatment hemorrhoids. This study aimed to evaluate the efficacy of Ruiyun procedure for hemorrhoids combined simplified Milligan–Morgan hemorrhoidectomy with dentate line-sparing (RPH + sMMH) to treat grade III/IV hemorrhoid. Methods Total 452 patients with hemorrhoids of grade III/IV were retrospectively reviewed in China-Japan Friendship Hospital, 244 cases were assigned to RPH + sMMH group, and 208 cases in MMH group. The primary efficacy outcome was rate of curative at 3 month after operation, and the recurrence rate within 12 months post operation. Secondary efficacy outcomes included wound healing time, time required to resume normal work, constipation symptom, quality of life, and pain post operation was also evaluated. The safety outcome included postoperative complications. Results There were no differences between the two groups in demographic characteristics. There was no statistically significant difference between the two groups in the curative rate. The recurrence rate after 12 months post operation in the RPH + sMMH (3.0%) was significantly lower than the sMMH group (7.8%) (P = 0.032). The wound healing time was significantly shorter in RPH + sMMH group than that in MMH group (P < 0.001). The time required to resume normal work in the RPH + sMMH group was significantly shorter than MMH group (P < 0.001). Compared with the MMH group, the RPH + sMMH therapy preserve better life quality and lower constipation symptom (all P < 0.05). Patients who underwent RPH + sMMH had significantly less postoperative pain than MMH therapy. The total rate of patients with postoperative complications in the RPH + sMMH group (8.6%) was significant lower than the MMH group (16.3%) (P = 0.012). Conclusion RPH + sMMH may more effective in treating patients with III/IV hemorrhoids, which indicated lower recurrence rate, lower postoperative complications and pain, shorter recovery and return to normal life.
