EP16.04: Three‐dimensional (3D) hysterosalpingo‐contrast‐sonography (HyCoSy) with new contrast lignosal (mixture of lignocaine 2% jelly and normal saline) for the assessment of tubal patency

Abstract

To assess the accuracy of 3D HyCoSy using the new contrast lignosal (mixture of 2% lignocaine jelly and normal saline) for the evaluation of tubal patency in infertile women. It is a prospective observational single centre study. We have recruited 35 patients undergoing 3D HyCoSy with lignosal contrast before standard diagnostic laparoscopy with chrompertubation (lap and dye). Tubal patency was assessed by our new contrast lignosal using the GE Voluson expert with 5-9 3D TVS probe with automated coded contrast imaging software. Initially all patients underwent 2D real time HyCoSy with lignosal contrast and tubes visualised as echogenic and spill seen from fimbrial end as shower and simultaneously 3D volume acquisition of tubes done in all cases and findings were compared with the results of lap and dye. For detecting tubal patency among the 70 fallopian tubes assessed, 3D HyCoSy with lignosal had a sensitivity of 92%, specificity of 85%, positive and negative predictive values of 86% and 91% respectively, and diagnostic accuracy of 90%. The test positive rates of 3D HyCoSy with lignosal versus lap and dye were not significantly different. Further, 7 patients conceived after 2-3 months of procedure. Transvaginal HyCoSy with new contrast lignosal with 3D volume acquisition of entire tubes and uterus was found to be very accurate and safe and less expensive, non-invasive procedure for tubal patency evaluation.
