Objective: To explore the application value of transvaginal ultrasound combined with abdominal ultrasonography in the diagnosis of ectopic pregnancy, and provides the basis for early diagnosis of ectopic pregnancy.

Methods: The clinical data of 106 cases of patients with ectopic pregnancy diagnosed by operation or conservative treatment admitted to our hospital from December 2011 to December 2013 were analysed retrospectively, all patients were examined by transvaginal ultrasound and abdominal ultrasonography in order to observe whether there were abnormality in the ovary or beside uterus of the patients, and the positive rate and missed diagnosis rate of ectopic pregnancy were compared among transvaginal ultrasonography group, transabdominal ultrasonography group, and two combined examinations group.

Results: The positive rate of yolk sac, fetal bud, heart beat and pelvic effusion through abdominal ultrasonography were all significantly lower than that of transvaginal ultrasonography (P<0.05); in 101 cases of patients with ectopic pregnancy diagnosed by the combination of vaginal ultrasound and abdominal ultrasound, the diagnostic accordance rate was 95.28%, and 5 cases were missed diagnosis, accounting for 4.72%; in 79 cases of patients with ectopic pregnancy diagnosed by simple abdominal ultrasound, the diagnostic accordance rate was 74.53%, and 27 cases were missed diagnosis, accounting for 25.47%; in 82 cases of patients with ectopic pregnancy diagnosed by simple transvaginal ultrasonography, the diagnostic accordance rate was 77.36%, and 24 cases were missed diagnosis, accounting for 22.64%. Compared with simple abdominal ultrasound and transvaginal ultrasound, the difference of diagnostic accordance rate by transvaginal ultrasound combined with abdominal ultrasound were statistically significant (P<0.05). However, the diagnostic accordance rate of transvaginal ultrasonography and abdominal ultrasonography were similar, and the difference was not statistically significant (P>0.05).

Conclusion: Transvaginal ultrasound combined with abdominal ultrasound can significantly improve the diagnostic accordance rate of ectopic pregnancy, provide a more convenient and quicker diagnostic method, and improve the accuracy of diagnosis. Thus, it is worthy of clinical application.
