目的 探讨曼月乐宫内节育器对预防子宫内膜息肉复发的效果。方法 以本院2010年1月至2011年12月间收治的80例子宫内膜息肉手术切除后患者为研究对象，随机分为观察组与对照组，所有患者均进行宫腔镜下息肉电切术，观察组术后应用曼月乐宫内节育器，对照组术后不予放置。比较两组患者治疗前后的复发率、子宫内膜厚度、血红蛋白含量以及月经情况。结果 观察组患者的复发率、子宫内膜厚度皆明显小于对照组 (均P<0.05)；血红蛋白含量高于对照组，月经情况优于对照组 (均P<0.05)。结论 曼月乐宫内节育器可以有效预防子宫腔镜下息肉电切术后患者的复发，降低患者子宫内膜增生程度，改善月经情况和血红蛋白含量。

Objective To investigate the effect of intrauterine device in the relapse prevention among the patients after endometrial polyp curettage. Method 80 patients after endometrial polyp curettage were divided into objective group and the control group. The intrauterine device was used in the objective group. The difference of hemoglobin level, menstruation degree, the distribution of intrauterine hormone receptor, endometrial thickness and the recurrence rate between the two groups was compared. Results The hemoglobin level in objective group was higher than that of control group. There was a significant development in the menstruation degree in the objective group. The distribution of intrauterine hormone receptor, endometrial thickness and the recurrence rate in objective group were lower than that in the control group. Conclusions It would get a satisfactory effect to use intrauterine device in the relapse prevention among the patients after endometrial polyp curettage, with better clinical effect and less recurrence events.
