To evaluate the effect of procedure for prolapse and hemorrhoids (PPH) for mixed hemorrhoids, by comparison short- and long-term complications of Milligan Morgan (M-M) and PPH.

Between January 2008 and February 2012, one hundred and ninety-eight cases with mixed hemorrhoids were collected from the 101st Hospital of PLA. According to the mode of operation, 87 cases were divided into Group PPH, and 111 cases in Group M-M. The surgical index, short- and long-term effect, and follow-up between the two groups were compared.

All the 198 patients were cured and discharged. Compared with Group M-M, the VAS pain score in Group PPH had obvious advantage (t=2.292, P=0.035); however, urine retention was more likely to occur (Z=-2.219, P=0.026), with higher cost (t=7.490, P=0.000). The follow-up rate was 100.0%, and the follow-up time was 50-90 (74±19.1) months. The recurrence rate of Group PPH was 32.2% (28/87), which was significantly higher than that in Group M-M (27.0%, 30/111) (χ²=0.626, P=0.037). There were no significant differences in the total complication (28.7% vs 31.5%), reoperation rate (11.5% vs 7.2%) and total satisfaction between Group PPH and Group M-M.

The long-term recurrence rate of PPH is high. As supplement to the traditional method for mixed hemorrhoid operation, it should be strictly grasped and chosen carefully.
