经阴道超声检测在诊断宫角妊娠患者中的应用效果分析

Application of transvaginal ultrasound in diagnosis of cornual pregnancy

目的对经阴道超声诊断宫角妊娠的价值进行探究。方法选取2016年3月~2018年1月于我院接受治疗的疑似宫角妊娠患者共102例,根据不同检查方法,将其设为观察组、对照组两组,每组各51例。所有患者均经本人同意并签署知情书,通过本院医学伦理会批准。观察组患者经阴道超声彩色多普勒进行检查,对照组患者经腹超声彩色多普勒进行检查,比较两组检测结果的阴性预测值、阳性预测值、检测灵敏度、特异度及约登指数。结果两组检测阳性预测值、检测灵敏度比较不具统计学意义(P>0.05);观察组检测阴性预测值、检测特异度、约登指数高于对照组(P<0.05)。结论经阴道超声对宫角妊娠患者的诊断具有更高灵敏度,成像更直观,诊断更准确,值得临床推广。

Objective To explore the value of transvaginal ultrasonography in the diagnosis of uterine horn pregnancy.Methods A total of 102 patients with suspected angular pregnancy who received treatment in our hospital from March 2016 to January 2018 were selected.According to different examination methods,they were divided into observation group and control group,with 51 cases in each group.All patients were approved by the medical ethics committee of our hospital with my consent and signed the informed letter.Patients in the observation group underwent transvaginal ultrasonography,and patients in the control group underwent transabdominal ultrasonography.The negative predictive value,positive predictive value,detection sensitivity,specificity and Jordan index of the test results in the two groups were compared.Results There was no significant difference in positive predictive value and detection sensitivity between the two groups(P>0.05).The negative predictive value,specificity and Jordan index of the observation group were significantly higher than those of the control group(P<0.05).Conclusion Transvaginal ultrasonography has higher sensitivity,more intuitive imaging and more accurate diagnosis in the diagnosis of angular pregnancy,which is worthy of clinical promotion.
