摘要:

目的:探讨宫腔镜子宫内膜息肉切除术后首次冻融胚胎移植(frozen-thawed embryo transfer,FET)周期中,2种不同内膜准备方案对助孕活产结局的影响。方法:回顾性分析2021年1月—2023年7月接受宫腔镜子宫内膜息肉切除术后首次FET治疗符合入组条件的526例患者的临床资料。根据内膜准备方案将患者分为人工周期组(A组,277例)和降调节人工周期组(B组,249例),比较2组患者的一般资料、FET周期情况和妊娠结局,并分析活产结局的影响因素。结果:B组的基础黄体生成素、基础雌二醇、抗米勒管激素、FET周期转化日子宫内膜厚度、移植囊胚比例均高于A组,差异有统计学意义(均P<0.05)。B组的种植率高于A组(P=0.014),但2组的临床妊娠率、流产率、持续妊娠率和活产率比较,差异无统计学意义(均P>0.05)。在控制混杂因素后,二元Logistic回归分析显示,2种内膜准备方案不是活产结局的影响因素(P>0.05)。结论:宫腔镜子宫内膜息肉切除术后首次FET周期中,人工周期与降调节人工周期内膜准备方案的活产结局相似,鉴于降调节人工周期方案治疗费用高、治疗时间长,可优先选择人工周期方案。

Abstract:

Objective: To investigate the effects of two endometrial preparation protocols on the outcomes of the first frozen-thawed embryo transfer (FET) cycle after hysteroscopic endometrial polypectomy. Methods: A retrospective analysis was conducted on the clinical data of 526 patients who underwent the first FET treatment after hysteroscopic endometrial polypectomy, from January 2021 to July 2023. Patients were divided into two groups based on the endometrial preparation protocol, the hormone replacement therapy (HRT) group (Group A, 277 cases) and the gonadotropin releasing hormone agonist (GnRH-a)-HRT group (Group B, 249 cases). The general characteristics, FET cycle parameters, and pregnancy outcomes of the two groups were compared. And the influencing factors of live birth outcome were analyzed. Results: Basal luteinizing hormone, basal estradiol, anti-Müllerian hormone, endometrial thickness on the transformation day of the FET cycle, and the proportion of transferred blastocyst in Group B were all significantly higher than those in Group A (all P<0.05). The implantation rate in Group B was significantly higher than that in Group A (P=0.014). There were no significant differences in clinical pregnancy rate, miscarriage rate, ongoing pregnancy rate, and live birth rate between the two groups (all P>0.05). After controlling the confounding factors, binary Logistic regression analysis showed that the endometrial preparation protocol was not the impact factor of live birth outcome (P>0.05). Conclusions: In the first FET cycle following hysteroscopic endometrial polypectomy, both HRT protocol and GnRH-a-HRT protocol can achieve similar live birth outcome. Considering that the GnRH-a-HRT regimen involves higher treatment costs and longer treatment duration, the conventional HRT protocol may be preferred as the first choice.
