目的：探讨不同时机宫腔镜检查对反复胚胎移植未孕患者后续体外受精-胚胎移植（IVF-ET）临床妊娠结局的影响。方法：回顾性分析2025年1月至2025年10月于东莞康华医院生殖医学科就诊的206例行IVF-ET助孕研究对象的临床资料。根据宫腔镜检查时机分为三组：A组（胚胎移植前检查，n=82）、B组（胚胎移植1次失败后检查，n=70）、C组（胚胎移植2次失败后检查，n=54）。比较三组研究对象后续IVF-ET周期的临床妊娠率。结果：三组研究对象基线年龄、不孕年限、BMI、AMH等指标差异无统计学意义（P>0.05）。总人群临床妊娠率为53.59%（97/206），其中A组妊娠率为72.0%（59/82），B组为35.7%（25/70），C组为24.1%（13/54），组间差异有统计学意义（P<0.001）。免疫双染阳性研究对象占86.27%（176/206），其在组间分布均衡，未改变主要结论。结论：对于IVF-ET助孕研究对象，胚胎移植前进行宫腔镜检查并处理异常，可能与后续临床妊娠率升高相关；延迟至1次或2次胚胎移植失败后再检查，妊娠获益可能大幅降低。提示胚胎移植前常规行宫腔镜评估的必要性。

Objective: To investigate the impact of different timing of hysteroscopy on the subsequent clinical pregnancy outcomes of patients with recurrent embryo transfer failure undergoing in vitro fertilization - embryo transfer (IVF-ET). Methods: The clinical data of 206 patients who underwent IVF-ET assisted pregnancy treatment at the Reproductive Medicine Department of Dongguan Kanghua Hospital from January 2025 to October 2025 were retrospectively analyzed. The patients were divided into three groups based on the timing of hysteroscopy: Group A (examined before embryo transfer, n = 82), Group B (examined after one failed embryo transfer, n = 70), and Group C (examined after two failed embryo transfers, n = 54). The clinical pregnancy rates of the subsequent IVF-ET cycles of the three groups were compared. Results: There were no statistically significant differences in baseline age, duration of infertility, BMI, AMH, etc. among the three groups (P > 0.05). The overall clinical pregnancy rate of the population was 53.59% (97/206), with the pregnancy rates in Group A being 72.0% (59/82), in Group B 35.7% (25/70), and in Group C 24.1% (13/54). The differences among the groups were statistically significant (P < 0.001). Immunobright staining positive study subjects accounted for 86.27% (176/206), and their distribution among the groups was balanced, without changing the main conclusion. Conclusion: For patients undergoing IVF-ET assisted pregnancy treatment, performing hysteroscopy and treating abnormalities before embryo transfer may be associated with an increased subsequent clinical pregnancy rate; delaying the examination until one or two failed embryo transfers may significantly reduce the pregnancy benefit. It suggests the necessity of routine hysteroscopy assessment before embryo transfer.

Objective To explore the clinical efficacy and safety of hysteroscopy combined with contraceptives in the treatment of endometrial polyps. Methods From February 2016 to December 2017, 160 patients with endometrial polyps were randomly selected and divided into control group (80 cases treated by hysteroscopy) and observation group (80 cases treated by hysteroscopy combined with drospirenone and ethinyl estradiol tablets). The differences of clinical efficacy and adverse reactions between the two groups were compared. Results Compared with the control group, the observation group had better menstruation improvement effect and lower recurrence rate. The difference was statistically significant (P<0.05). In the comparison of adverse reactions, there was no significant difference between the observation group and the control group (P>0.05). Conclusion Hysteroscopy combined with contraceptives has achieved certain clinical efficacy in the treatment of endometrial polyps, and the adverse reactions are not significant, which can be popularized and applied.

Objective To explore the clinical significance of B-ultrasound, MRI and hysteroscopy in the diagnosis of uterine space occupying lesions. Methods 108 patients with suspected uterine space occupying lesions admitted to our hospital from January 1 to December 31 2017 were selected as the study objects. All patients were examined by vaginal color Doppler ultrasound, MRI and hysteroscopy before uterine operation. Compared with the results of pathological examination, the sensitivity and specificity were analyzed. Results Among the 108 patients, 27 had no pathological changes in uterine cavity, 39 had endometrial polyps, 27 had endometrial hyperplasia, 10 had submucous myoma, and 5 had endometrial cancer. The sensitivity of B-ultrasound, MRI and hysteroscopy were 72.84%, 71.60% and 75.31% respectively, and the specificity were 62.96%, 85.19% and 66.67% respectively. The sensitivity of B-ultrasound+MRI in the diagnosis of submucous myoma and endometrial carcinoma was 100% and the specificity was 87.76% and 99.03%, respectively. The sensitivity of B-ultrasound+MRI+hysteroscopy in the diagnosis of endometrial hyperplasia, submucous myoma and endometrial carcinoma was 100%. Conclusion Most of the uterine space occupying lesions are benign. B-ultrasound combined with hysteroscopy and MRI may improve the diagnosis rate. The high-risk group of endometrial cancer should be examined by B-ultrasound and MRI, and hysteroscopic biopsy would be performed only when necessary.

目的 研究宫腔镜治疗子宫粘连性所致不孕症的临床疗效,为临床相关治疗提供参考。方法 选取我院于2016年11月—2017年11月收治的180例子宫粘连性所致不孕症患者作为观察对象,按照随机数表法平均分成两组。其中观察组90例采用宫腔镜治疗,对照组90例采用传统输卵管通液治疗。对比两组患者治疗前后性激素水平、临床指标及妊娠结局变化。结果 两组间相比,治疗前后 LH、FSH、E2、P等性激素水平无变化,且治疗后观察组与对照组相比,差异均无统计学意义(P>0. 05);两组间相比,治疗后观察组患者的术中出血量、手术时间、住院天数均少于对照组,差异有统计学意义(P<0. 05);两组间相比,治疗后观察组患者的足月分娩率高于对照组,早产率低于对照组,差异有统计学意义(P<0. 05)。结论 宫腔镜治疗子宫粘连性所致不孕症,与传统输卵管通液治疗相比,对性激素水平无影响,但可显著降低患者住院时间及术中出血量,有效提高足月分娩率,值得在临床上推广。
