OBJECTIVE: To investigate the efficacy of the procedure for prolapse and hemorrhoids (PPH) combined with external hemorrhoids excision in the treatment of III or IV mixed hemorrhoids.

METHODS: One hundred and twelve patients with III or IV mixed hemorrhoids admitted for surgical treatment were randomly divided into three groups: PPH 1 group (34 cases), PPH2 group (36 cases), and Milligan-Morgan group (42 cases). PPH1 group received the standard PPH operation, PPH2 received PPH and external hemorrhoids excision, and Milligan-Morgan group received Milligan-Morgan hemorrhoidectomy. Postoperative 24 h-pain index, pain index when defecating, bleeding, anal discomfort feeling , wound edema, the ability of controlling feces, operating time, hospitalization time and charges were recorded. The change of anal dynamics was detected by anorectal manometry. All the patients were followed-up for 0.5-1 year.

RESULTS: There were no significant differences among the three groups in bleeding, anal discomfort feeling, the ability of controlling feces (P>0.05). The postoperative 24 h-pain index of PPH1 group was lower than those of the other two groups (P<0.05). PPH1 group and PPH2 group were better than Milligan-Morgan group in pain index when defecating, wound edema, operating time, and hospitalization time (P<0.05). Milligan-Morgan group was better than the other two groups in postoperative urinary retention and hospital charges (P<0.05). The change of anal duct pressure of Milligan-Morgan group was less than those of the other two groups (P<0.05). Within 0.5-1.0 year follow-up, 3 patients got thrombosed external hemorrhoid in PPH1 group, 2 patients recurred and 1 patient got thrombosed external hemorrhoid in Milligan-Morgan group, no recurred patients in PPH2 group.

CONCLUSION: PPH combined with external hemorrhoid excision is a safe and effective treatment for mixed hemorrhoids, which is suitable for mixed hemorrhoids with severe external hemorrhoids.
