摘　　要：目的比较经阴道超声与经腹部超声诊断宫外孕的准确性及预测价值。方法选择疑似宫外孕患者215例,均接受经阴道超声检查及经腹部超声检查。对比两种检查的诊断效能。结果经阴道超声检查的诊断准确性、敏感性、特异性、阳性预测值与阴性预测值分别为96.74%(208/215)、96.97%(192/198)、94.12%(16/17)、99.48%(192/193)、72.73%(16/22),均高于经腹部超声检查的82.12%(183/215)、86.87%(172/198)、64.71%(11/17)、96.63%(172/178)、29.73%(11/37)(P<0.05)。经阴道超声检查对附件包块检出率、胚芽胎心检出率、卵黄囊检出率、盆腔积液检出率分别为87.44%、47.44%、53.02%、68.37%,均高于经腹部超声的63.72%、16.74%、36.74%、54.88%(P<0.05)。结论经阴道超声检查对宫外孕的诊断效能高于经腹部超声检查,且对于典型超声特征的检出率更佳,值得临床推广使用。Objective To compare the accuracy and predictive value of transvaginal ultrasound and transabdominal ultrasound in diagnosing ectopic pregnancy.Methods 215 patients with suspected ectopic pregnancy were examined by transvaginal ultrasonography and transabdominal ultrasonography.The diagnostic efficiency of the two tests was compared.Results The diagnostic accuracy,sensitivity,specificity,positive predictive value and negative predictive value of the transvaginal ultrasound were 96.74%(208/215),96.97%(192/198),94.12%(16/17),99.48%(192/193),72.73%(16/22),respectively,which were higher than 82.12%(183/215),86.87%(172/198),64.71%(11/17),96.63%(172/178),29.73%(11/37)of the abdominal ultrasonography(P<0.05).The detection rates of adnexal mass,embryo fetal heart,yolk sac and pelvic effusion of the transvaginal ultrasound were 87.44%、47.44%、53.02%、68.37%,respectively,which were higher than 63.72%、16.74%、36.74%、54.88% of the transabdominal ultrasound(P<0.05).Conclusion The transvaginal ultrasonography is more effective than transabdominal ultrasonography in the diagnosis of ectopic pregnancy,and the detection rates of typical ultrasonic features are better,which is worthy of clinical popularization.
