ABSTRACT
Objective To compare the clinical effects of RPH combined with Milligan and PPH in the treatment of severe mixed hemorrhoids. Methods 168 patients with severe mixed hemorrhoids were assigned to a study group or a control group,84 patients for each group. The control group received PPH therapy,while the study group received RPH combined with Milligan procedure. Results The procedures were completed successfully in all the patients. The postoperative hospital stay and surgical duration were shorter and the amount of bleeding was smaller in the study group than in the control group(P<0.05). Three months after surgery,the rate of compli-cations including urinary retention,anal incontinence,anorectal stenosis,and secondary anal fissure was lower in the study group than in the control group(P < 0.05). The total effective rate was 97.6% in the study group and 85.7% in the control group,with a higher rate in the study group(P<0.05). Anal PSV and EDV values were lower in both groups three months after the procedures as compared with one day before the procedures(P<0.05),and the values were smaller in the study group than in the control group(P<0.05). Conclusions Milligan combined with RPH in the treatment of severe mixed hemorrhoids can reduce hemorrhoids blood flow. This procedure is mini-mally invasive and it can reduce the development of postoperative complications and improve efficacy.
