目的:探讨不孕患者子宫内膜息肉(EP)发生的相关因素及宫腔镜下EP清除术对助孕效果的影响。方法:接受宫腔镜检查的不孕患者855例,其中EP患者202例(EP组),宫腔正常者653例(对照组)。分析年龄、体质量指数、不孕年限、不孕类型及合并症等与EP发生的相关性;采用宫腔镜术联合药物(三联疗法)治疗,分析术后助孕效果。结果:EP发病率为23.6%,原发不孕、不孕年限>5年者EP发病率增高,EP患者合并子宫内膜异位症、子宫肌瘤、月经稀发几率明显增高(P<0.05);患者接受“三联疗法”治疗后,经助孕后临床妊娠率与对照组比无差异(P>0.05)。结论:宫腔镜手术有助于提高EP检出率,联合药物治疗的“三联疗法”是治疗EP的有效方法。 Objective: To investigate the factors related to the occurrence of endometrial polyps (EP) in infertile patients and the effect of hysteroscopic EP resection on the effect of pregnancy. Methods: A total of 855 infertile women undergoing hysteroscopy were enrolled, including 202 patients with EP (EP group) and 653 women with normal uterine cavity (control group). Analysis of age, body mass index, duration of infertility, type of infertility and complications associated with the occurrence of EP; the use of hysteroscopy combined with drugs (triple therapy) treatment, analysis of postoperative pregnancy benefit. Results: The incidence of EP was 23.6%. The incidence of EP was higher in patients with primary infertility and infertility> 5 years. The incidence of endometriosis, uterine fibroids and menstruation was significantly higher in patients with EP (P <0.05 ). After receiving “triple therapy”, the clinical pregnancy rate after the pregnancy was no significant difference compared with the control group (P> 0.05). Conclusion: Hysteroscopy can help improve the detection rate of EP. Combination therapy with “triple therapy” is an effective way to treat EP.
