Transvaginal scan versus transabdominal scan for gestational sac detection in the early first trimester of pregnancy in sudanese ladies

Objective: This study was designed to compare the efficiency between transvaginal scan (TVS) over transabdominal scan (TAS) in the early detection for the presence of gestational sac in the first trimester of pregnancy. Methods: A total of 100 women with an age that ranged between 15 to 45 years old and showed a positive pregnancy test during first trimester of pregnancy, had transvaginal and transabdominal ultrasound in order to compare the value of these two techniques for the detection of gestational sac. Results: TVS found to be significant and superior when compared with TAS in detection for the presence of gestational sac, where Pearson Chi-Square value=32.727 and P value=.000; [Pearson Chi-Square=32.727 and P=.000]. Despite of this fact, knowledge of the finding on TAS made it easier to interpret the transvaginal findings. Although TVS have limitations such as locate lesions outside the pelvis and needs further counseling and education. Conclusion: TVS is more efficient in accessing the presence of gestational sac in early first trimester of pregnancy rather than the TAS.
