经阴道彩超联合性激素检测在宫外孕早期诊断中的价值分析

Objective To compare the diagnostic value of transvaginal color ultrasound examination combined with sex hormone [β-subunit human chorionic gonadotropin(β-HCG), progesterone(P)] testing in the early diagnosis of ectopic pregnancy. Methods A total of 92 patients with suspected ectopic pregnancy admitted to Angels Maternity Hospital affiliated to Northwest University from February 2024 to February 2026 were selected. After admission, all patients underwent transvaginal color ultrasound examination and sex hormone(β-HCG, P) testing. The gold standard was laparoscopic pathological examination. The study explored the diagnostic value of transvaginal color ultrasound examination combined with sex hormone(β-HCG, P) testing in the early diagnosis of ectopic pregnancy. Results The results of the gold standard laparoscopic pathological examination showed that 52 cases were diagnosed with ectopic pregnancy and 40 cases were diagnosed with other diseases. The results of the sex hormone(β-HCG, P) test showed that 50 cases were diagnosed with ectopic pregnancy and 42 cases were diagnosed with other diseases. Transvaginal ultrasound examination showed that 46 cases were diagnosed with ectopic pregnancy and 46 cases were diagnosed with other diseases. Transvaginal ultrasound examination combined with sex hormone(β-HCG, P) test showed that 51 cases were diagnosed with ectopic pregnancy and 41 cases were diagnosed with other diseases. The sensitivity, accuracy, and specificity of the sex hormone(β-HCG, P) test were 76.92%, 76.09%, and 75.00%, respectively. The sensitivity, accuracy, and specificity of the transvaginal ultrasound examination were 78.85%, 82.61%, and 87.50%, respectively. The sensitivity, accuracy, and specificity of the combined transvaginal ultrasound examination and sex hormone(β-HCG, P) test were 96.15%, 96.74%, and 97.50%, respectively. The sensitivity, accuracy, and specificity of transvaginal ultrasound combined with sex hormone(β-HCG, P) testing were higher than those of single examination(P<0.05). Conclusion In the early diagnosis of ectopic pregnancy, transvaginal color ultrasound examination combined with sex hormone(β-HCG, P) testing can further improve the diagnostic value and guide subsequent treatment plans.
