[Efficacy of the procedure for prolapse and hemorrhoids combined with external hemorrhoids excision in the treatment of III or IV mixed hemorrhoids].
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.


CONCLUSIONS
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.
