ABSTRACT

Objective: To compare transvaginal and transabdominal ultrasound in the diagnosis of ectopic pregnancy. Methods: This cross-sectional study was a prospective study on 35 pregnant patients, conducted for a duration of nine months, from March 2021 to November 2021. All women with suspicion of ectopic pregnancy were evaluated by both transabdominal and transvaginal sonography. Diagnosis made on transabdominal or transvaginal sonography ultrasound was later confirmed by histopathology. Results: Ultrasonographic findings of ectopic pregnancy were seen, including presence of extra uterine gestational sac or complex mass 94.2 %, absence of gestational sac in uterus 85.7%, fluid in the pouch of Douglas 65.7%, endometrial thickness > 10mm in 48.57% enlargement of uterus 28.57%. More than one finding was seen in several patients. Most common age group with pelvic masses was between 26-30 years. The study result revealed that sensitivity of transabdominal and transvaginal ultrasonography was 80.95% and 95.65% respectively. Specificity of transabdominal & transvaginal ultrasonography was 83.33% & 92.85%. Diagnostic accuracy of transabdominal ultrasonography was 91.43% and transvaginal ultrasonography was 85.71%. Conclusion: Transvaginal ultrasonography is superior to transabdominal ultrasonography for early detection of ectopic pregnancy.
