Purpose:
To explore the safety and efficacy of Ruiyun procedure for hemorrhoids (RPH) or RPH with the simplified Milligan-Morgan hemorrhoidectomy (sMMH) in the treatment of mixed hemorrhoids.
Methods:
This is a randomized, controlled, balanced, multicenter study of 3000 patients with mixed hemorrhoids. The outcomes and postoperative complications were compared between 5 types of surgeries.
Results:
The efficacy rate was the highest in patients who received RPH+sMMH and decreased in the following order: patients who received RPH alone, MMH alone, procedure for prolapse and hemorrhoids (PPH) alone, and PPH+sMMH ( P < .05). The operation time was the shortest in patients who received RPH alone and increased in the following order: patients who received RPH+sMMH, PPH alone, MMH alone, and PPH+sMMH ( P < .01). The duration of postoperative hospitalization stay was the shortest in patients who received RPH alone and increased in the following order: PPH alone, RPH+sMMH, PPH+sMMH, and MMH alone ( P < .01). The incidence of postoperative hemorrhage, uroschesis, anal fissure, crissum hematoma or thrombosis, and anorectal stenosis was significantly lower in patients who received RPH+sMMH than in patients who received the other 4 types of surgical treatments ( P < .05, P < .01). No significant differences in postoperative rectovaginal fistula and anal incontinence were observed between the 5 groups of patients.
Conclusions:
RPH with or without simplified MMH can reduce the incidence of postoperative complications and improve the curative efficacy in the treatment of patients with mixed hemorrhoids.
