ObjectiveTo investigate the clinical effect and the incidence of postoperative complications of Milligan-Morgan hemorrhoids combined with reducing tension of alary incision in the treatment of annular mixed hemorrhoids.MethodsProspectively collected 120 patients with annular mixed hemorrhoids who received treatment from the Department of Colorectal Surgery of Bazhong Hospital of Traditional Chinese Medicinel during the April, 2016 to October, 2018. All of the 120 patients with annular mixed hemorrhoids were randomly divided into the experimental group and the control group, with 60 patients in each one group. Patients in the experimental group was treated with Milligan-Morgan hemorrhoids combined with reducing tension of alary incision, while patients in the control group with conventional Milligan-Morgan hemorrhoid.ResultsIn the experimental group, 49 cases were cured, 11 cases showed obvious effect; in the control group, 39 cases were cured, 20 cases showed obvious effect, and 1 case was effective. The curative effect in experimental groups was better than that of the control group (Z=–2.090, P=0.037), and the effective rates of these two group were both 100% in total. The mean healing time was (19±3) d (14–21 d) in the experimental group and (21±3) d (14–24 d) in the control group, respectively, which was better in the experimental group (Z=–13.636, P<0.001). Experimental group with lower score of wound pain, hemafecia, and anal margin edema, which were much better than control group on 1 d and 3 d after operation (P<0.05). There was no statistically significant differences on incidence of uroschesis and recurrence rate between the two groups (P>0.05).ConclusionsMilligan-Morgan hemorrhoids combined with reducing tension of alary incision in the treatment of annular mixed hemorrhoids has good clinical effect and deserves clinical application.
