Clinical value of transabdominal ultrasonography versus transvaginal ultrasonography in the early diagnosis of ectopic pregnancy / 中国基层医药

ABSTRACT

Objective:To investigate the clinical value of transabdominal ultrasonography versus transvaginal ultrasonography in the early diagnosis of ectopic pregnancy. Methods:A total of 100 patients with suspected early ectopic pregnancy who received treatment in Luanping Shengjian Hospital between April 2019 and April 2021 were included in this study. All of them underwent transabdominal and transvaginal ultrasonography. Surgical pathological results were used as the gold standard to analyze the diagnostic efficacy of the two examination methods. The detection rate of ectopic pregnancy by ultrasonography was compared between the two examination methods.Results:Early ectopic pregnancy was detected in 59 cases by transabdominal ultrasonography, among which seven cases were misdiagnosed and 10 cases were missed. Early ectopic pregnancy was detected in 60 cases by transvaginal ultrasonography, among which one case was misdiagnosed and three cases were missed. The sensitivity, specificity and accuracy of transvaginal ultrasonography in the early detection of ectopic pregnancy were 95.2%, 97.4% and 96.0%, respectively, which were significantly higher than those of transabdominal ultrasonography (83.9%, 81.6%, 83.0%, χ2 =4.21, 5.03, 8.99, P = 0.040, 0.025, 0.003). Transvaginal ultrasonography showed that detection rates of accessory mass, yolk sac, embryo, intrauterine pseudopregnancy sac, pelvic effusion and original vascular fluctuation were 88.7%, 50.0%, 24.2%, 22.6%, 12.9%, 87.1%, respectively, which were significantly higher than those of transabdominal ultrasonography (64.5%, 19.4%, 4.8%, 4.8%, 1.6%, 56.5%, χ2 = 10.13, 12.85, 9.36, 8.25, 5.87, 14.37, P = 0.001, < 0.001, = 0.002, = 0.004, = 0.015, < 0.001). Conclusion:Transvaginal ultrasonography is superior to transabdominal ultrasonography in the early detection of ectopic pregnancy and has a higher detection rate of sonographic manifestation than transabdominal ultrasonography.
