Analysis of the effect of combined vaginal and abdominal ultrasound in the diagnosis of ectopic pregnancy

This study investigates the role of vaginal ultrasound and abdominal ultrasound in the diagnosis of ectopic pregnancy. A total of 240 patients with suspected ectopic pregnancy admitted to Longquanyi District People's Hospital from January 2020 to December 2024 were enrolled, and all patients underwent vaginal ultrasound and abdominal ultrasound. The diagnostic effect, the detection rate of sonographic features, and the detection rate of different disease types were compared with the surgical pathological results (gestational villous tissue in the blood clot and visible villous matter) as the gold standard. In this study, 240 patients with suspected ectopic pregnancy were analyzed, and the results showed that the sensitivity, specificity, and accuracy of abdominal ultrasound, vaginal ultrasound, and combined examination were 89.04%, 93.15%, and 95.89%, respectively, and 42.86%, 57.14%, and 71.43%, respectively, and 85.00%, 90.00%, and 93.75%, respectively. There was no significant difference between the groups (P > .05). The detection rate of combined examination in embryo, yolk sac, original heart tube beat, pelvic effusion, adnexal mass, intrauterine pseudogestational sac, and extrauterine gestational sac was significantly higher than that of abdominal ultrasound or vaginal ultrasound alone (P < .05). There was no significant difference in the detection rate of fallopian tube pregnancy, ovarian pregnancy, abdominal pregnancy, and cervical pregnancy among the 3 examination methods (P > .05). The combined examination of vaginal ultrasound and abdominal ultrasound has high diagnostic efficacy in the diagnosis of ectopic pregnancy, which can effectively reduce missed diagnosis and misdiagnosis, clearly display relevant sonographic features, and help to determine the location of ectopic pregnancy.
