摘要:

目的:探讨影响反复种植失败(repeated implantation failure, RIF)患者宫腔镜内膜活检术后第1次胚胎移植临床妊娠结局的相关因素,为改善RIF患者临床妊娠率提供依据。方法:选取2015年9月—2017年9月于我院生殖医学中心行宫腔镜内膜活检术的RIF患者共136例,根据术后第1次胚胎移植后是否临床妊娠分为妊娠组及非妊娠组。记录2组患者的年龄、身高、体质量、不孕年限、不孕类型、宫腔镜治疗时期(子宫内膜增殖期/分泌期)、移植失败次数、移植前子宫内膜厚度、移植周期、移植距宫腔镜时间、移植胚胎类型(卵裂期胚胎=1、囊胚=2)及移植胚胎数量,对上述可能与临床妊娠相关的因素依次进行单因素分析及多因素Logistic回归分析,筛选出宫腔镜内膜活检术后RIF患者再次种植结局的影响因素并进行分析。结果:136例患者中共有70例术后第1次胚胎移植获得临床妊娠,妊娠率为51.5%。单因素分析结果显示,2组患者的平均年龄及移植胚胎类型比较差异有统计学意义(P<0.05)。多因素Logistic回归分析显示,患者年龄(OR=1.160,95%CI:1.041~1.292)及移植胚胎类型(OR=0.307,95%CI:0.108~0.873)是宫腔镜术后RIF患者再次妊娠的影响因素。结论:年轻和囊胚移植的RIF患者宫腔镜内膜活检术后胚胎移植更容易获得临床妊娠,而宫腔镜内膜活检术在月经周期中的治疗时机,不是影响术后第1次胚胎移植临床妊娠的相关因素。

Abstract:

Objective: To investigate the factors affecting the clinical outcomes of patients with repeated implantation failure (RIF) following hysteroscopy and endometrial biopsy, and to provide references for improving the clinical pregnancy rate of RIF patients.Methods: From September 2015 to September 2017, a total of 136 patients undergoing hysteroscopy and endometrial biopsy in our hospital were eligible for this study. All patients were diagnosed with RIF. Patients were divided into two groups (pregnancy group and non-pregnancy group) according to the presence of clinical pregnancy after the first embryo transplantation. Data of age, height, weight, infertility years, infertility types, hysteroscopy period (endometrial proliferation/secretion), transplant failure times, endometrial thickness, transfer cycle, time between transplantation and hysteroscopy, embryo type and number of embryos were collected by respectively reviewing patients′ medical records. Univariate analysis and multivariate logistic analysis were used to explore the influencing factors of clinical pregnancy following hysteroscopy and endometrial biopsy.Results: The incidence of clinical pregnancy following hysteroscopy and endometrial biopsy was 51.5% (70 of 136 cases). Univariate analysis showed the statistical differences in age and the type of embryo between the two groups (P<0.05). Multivariate Logistic regression analysis confirmed that the age (OR=1.160, 95%CI: 1.041-1.292) and type of embryo transplanted (OR=0.307, 95%CI: 0.108-0.873) were the influencing factors for the second pregnancy of patients with RIF after hysteroscopy.Conclusions: It is relatively easy for younger patients and those patients accepting blastocyst transplantation to obtain clinical pregnancy following the hysteroscopy and endometrial biopsy. The treatment timing of hysteroscopy and endometrial biopsy in the menstrual cycle is not a factor affecting the clinical pregnancy after the first postoperative embryo transfer.
