Abstract: Objective: To investigate the effect of surgical therapy for mixed hemorrhoid and to find a way to decrease post-surgery complication.Methods: One hundrend and eighty patients with severe mixed hemorrhoids were randomly assigned to receive hemorrhoidectomy using divest and scissors excision-ligation technique or Milligan-Morgan hemorrhoidectomy.Post-surgery complications and duration of treatment were recorded.Results: The average treatment time was 16.68 days in group one,and 24.63 days in group two.The total score of the first day post-surgery complication was 2.78±1.46 in group one,and 6.5±1.62 in group two(P<0.01).The total score of the fifth day post-surgery complication was 1.28±1.11 in group one,and 5.32±1.22 in group two(P<0.01).Conclusions: Hemorrhoidectomy using divest and scissors excision-ligation technique is easy to operate,with the advantages of a shorter length of hospital stay and a lower complication rate.
