阴道超声联合腹部超声在异位妊娠的诊断价值分析

An Analysis of the Diagnostic Value of Transvaginal Ultrasound Combined with Abdominal Ultrasound in Ectopic Pregnancy

目的:探讨阴腹超声联合在异位妊娠(EP)的诊断价值。方法:选取拟诊为EP的115例患者作为研究对象,所有患者均阴、腹超声检查。评估阴道超声、腹部超声单独或联合检查诊断结果,计算诊断效能,对比联合检查和单独检查对各类型EP的诊断准确率,分析阴道超声、腹部超声的图像。结果:①阴道超声灵敏度、准确率均高于腹部超声(P<0.05),联合检查灵敏度、准确率均高于阴腹超声单独检查(P<0.05),各检查单独及联合阳性预测值比较差异无统计学意义(P>0.05),联合检查阴性预测值高于阴道超声和腹部超声单独检查(P<0.05);②与腹部超声相比,联合检查和阴道超声诊断输卵管妊娠准确率、总准确率更高(P<0.05),联合检查诊断输卵管妊娠准确率、总准确率均高于阴道超声(P<0.05);③联合检查和阴道超声诊断EP符合率均高于腹部超声(P<0.05)。结论:阴腹联合超声有利于提高EP诊断效能,具有一定的临床应用价值。

Objective:To explore the diagnostic value of vaginal ultrasound combined with abdominal ultrasound in the diagnosis of ectopic pregnancy(EP).Methods:A total of 115 patients who were diagnosed as possible EP were selected for the study.All patients underwent transvaginal ultrasound and abdominal ultrasound.The diagnostic results of transvaginal ultrasound,abdominal ultrasound and combined examination were evaluated,and the diagnostic efficacy was calculated,and the diagnostic accuracy rates of each type of EP by combined examination and single examination were compared,and the images of transvaginal ultrasound and abdominal ultrasound were analyzed.Results:The sensitivity and accuracy rate of transvaginal ultrasound were higher than those of abdominal ultrasound(P<0.05),and the sensitivity and accuracy rate of combined examination were higher than those of transvaginal ultrasound or abdominal ultrasound(P<0.05).There was no significant difference in the positive predictive value of each examination alone or in combination(P>0.05),and the negative predictive value of combined examination was higher than that of transvaginal ultrasound or abdominal ultrasound(P<0.05).The accuracy rate of tubal pregnancy and total accuracy rate of combined examination and transvaginal ultrasound were higher than those of abdominal ultrasound(P<0.05),and the accuracy rate of tubal pregnancy and total accuracy rate of combined examination were higher than those of transvaginal ultrasound(P<0.05).The coincidence rate of combined examination and transvaginal ultrasound in the diagnosis of EP was higher than that of abdominal ultrasound(P<0.05).Conclusion:The combination of transvaginal ultrasound and abdominal ultrasound promotes the diagnostic efficacy of EP and has certain clinical application value.
