Methods A total of 68 patients with ectopic pregnancy admitted to Puyang Maternity and Child Care Centers from May 2019 to April 2021 were selected as the study group, and 68 cases with normal pregnancy in the same period were selected as the control group with a ratio of 1∶1. Vaginal ultrasound, β-HCG and progesterone testings were performed in both groups. The levels of β-HCG and progesterone in the two groups were compared. And the diagnostic results, diagnostic efficacy and predictive value of β-HCG, progesterone, transvaginal ultrasound and combination of the them for ectopic pregnancy were counted. Results The levels of β-HCG and progesterone in the study group were lower than those in the control group ( P<0.05). Among the 68 women with ectopic pregnancies and 68 cases of normal pregnancy, β-HCG testing identified 55 cases of ectopic pregnancy and 51 cases of normal pregnancy progesterone testing identified 54 cases of ectopic pregnancy and 52 cases of normal pregnancy transvaginal ultrasound confirmed 48 cases of ectopic pregnancy and 50 cases of normal pregnancy and the combination of the three examinations identified 63 cases of ectopic pregnancy and 64 cases of normal pregnancy. The sensitivity of β-HCG (80.88%, 55/68), progesterone (79.41%, 54/68) and transvaginal ultrasound (70.59%, 48/68) were lower than that of the combination of the three (92.65%, 63/68) in the diagnosis of ectopic pregnancy (P<0.05). The specificity of β-HCG (75.00%, 51/68), progesterone (76.47%, 52/68) and transvaginal ultrasound (73.53%, 50/68) were lower than that of the combination of the three (94.12%, 64/68),P<0.05. The accuracy of β-HCG (77.94%, 106/136), progesterone (77.94%, 106/136) and transvaginal ultrasound (72.06%, 98/136) were lower than that of the combination of the three (93.38%, 127/136),P<0.05. The missed diagnosis rate of β-HCG (19.12%, 13/68), progesterone (20.59%, 14/68) and transvaginal ultrasound (29.42%, 20/68) were higher than that of the combination of the three (7.35%, 5/68),P<0.05. The misdiagnosis rate of β-HCG (25.00%, 17/68), progesterone (23.53%, 16/68) and transvaginal ultrasound (26.47%, 18/68) were higher than that of the combination of the three (5.88%, 4/68),P<0.05. The positive predictive values (76.39%, 55/72 77.14%, 54/70 72.73%, 48/66) and negative predictive values (79.69%, 51/64 76.47%, 52/68 71.43%, 50/70) of β-HCG, progesterone and transvaginal ultrasound were lower than those of the combination of the three (94.03%, 63/67 92.75%, 64/ 69),P<0.05. Conclusions Transvaginal ultrasound combined with β-HCG and progesterone in the diagnosis of ectopic pregnancy can improve the sensitivity, specificity and accuracy of diagnosis, and reduce the occurrence of missed diagnosis and misdiagnosis, with good predictive value.
