目的研究对初次IVF-ET(体外受精-胚胎移植术)未成功并再次接受IVF-ET的不孕症患者实施宫腔镜仪器检查的应用及效果。方法抽选本院2013年3月~2014年9月接收的70例初次IVF-ET未成功并再次接受IVF-ET的不孕症患者，按照入院时间顺序抽取先进治疗周期的35例患者并归纳为对照组，而后进治疗周期的患者则列入实验组。在实施IVF-ET之前，对照组仅接受IVF-ET常规术前检查，未行宫腔镜检查，而实验组除常规术前检查外还接受宫腔镜仪器的诊查。结果实验组妇女妊娠成功概率为45.71%，而对照组妊娠成功概率为31.43%，妊娠成功的概率呈现明显区别<0.05。结论由于通过宫腔镜仪器为初次IVF-ET未成功并再次接受IVF-ET的妇女进行宫腔镜检查可提升妊娠成功的概率，所以建议应该积极的将宫腔镜检查列为IVF-ET术前常规例行检查。“,”Objective To study on the initial IVF-ET (IVF-ET) without success and again to accept the implementation of application and ef ect of hysteroscopic inspection instrument of IVF-ET in infertile patients. Methods In our hospital from 2013 March to 2014 selected in September eceived 70 cases of first IVF-ET were not successful y and accept IVF-ET infertility patientsagain, according to 35 cases patients of advanced treatment cycle time sequential extractionand summarized as control group, and then into the cycle of treatment were included in theexperimental group. Before implementing the IVF-ET, the control group only received routineinspection before IVF-ET surgery, not for hysteroscopy, while the experimental group in addition to conventional preoperative examination also received hysteroscopic diagnosis instrument.Results The experimental group women pregnancy success probability is 45.71%, while the control group, the pregnancy success probability is 31.43%, the probability of successful pregnancy showed significant dif erence between ( < 0.05). Conclusion Because for the first timeby hysteroscopy instrument IVF-ET is not successful and accept IVF-ET women againhysteroscopy can enhance the probability of successful pregnancy, so proposal should be actively the hysteroscopy is listed as IVF-ET preoperative routine examination.
