经阴道、经腹彩色多普勒超声诊断早期异位妊娠的诊断价值分析

Analysis of the Application Value of Transvaginal and Transabdominal Color Doppler Ultrasound in Diagnosing Early Ectopic Pregnancy

目的:分析和评估经阴道和经腹彩色多普勒超声在早期异位妊娠诊断中的效能。方法:采用前瞻性研究设计,对2022年6月1日至2024年3月1日期间的120例疑似早期异位妊娠患者进行两种超声检查,然后将检查结果分为两组,经阴道超声结果归为观察组,经腹超声结果归为对照组,并比较其诊断准确率和典型征象的检出率。结果:经阴道彩色多普勒超声检查的诊断准确率达到98.33%,显著高于经腹彩色多普勒超声的83.33%(P<0.05)。在检出早期异位妊娠的典型征象方面,经阴道超声在假孕囊(56.67%vs.31.67%)、原始心管搏动(55%vs.0.35%)、附件区包块(73.33%vs.53.33%)、盆腔积液(66.67%vs.31.67%)和外孕囊胚芽(51.67%vs.28.33%)的检出率均显著优于经腹超声(所有比较P<0.05)。结论:尽管两种方法均对早期异位妊娠的诊断具有参考价值,但经阴道彩色多普勒超声在准确性和典型征象检出方面表现更佳,建议在临床中优先采用。

Objective:To analyze and evaluate the efficacy of transvaginal and transabdominal color Doppler ultrasound in the diagnosis of early ectopic pregnancy.Methods:A prospective study design of 120 patients with suspected early ectopic pregnancy from June 1,2022 to March 1,2024.The patients underwent both transvaginal and transabdominal ultrasound examinations,and the results were subsequently categorized into two groups:the transvaginal ultrasound group(observation group)and the transabdominal ultrasound group(control group),and the diagnostic accuracy and detection rate of typical symbol were compared.Results:The diagnostic accuracy of transvaginal color Doppler ultrasound reached 98.33%,which was significantly higher than the 83.33%of transabdominal color Doppler ultrasound(P<0.05).For early ectopic pregnancy,transvaginal ultrasound was significantly better in pseudosac(56.67%vs.31.67%),primitive beats(55%vs.0.35%),accessory areas(73.33%vs.53.33%),pelvic effusion(66.67%vs.31.67%)and external cysts(51.67%vs.28.33%)(P<0.05 for all comparisons).Conclusion:Although both methods have reference value for the diagnosis of early ectopic pregnancy,transvaginal color Doppler ultrasound performs better in accuracy and typical symbolic detection,and it is recommended to be preferred in clinical practice.The limitation of this study is the small sample size,which may affect the generalizability of the results.
