Saline-Air Hysterosalpingo–Contrast Sonography Is Equivalent to the Modified Hysterosalpingogram Following Hysteroscopic Sterilization

Abstract

Purpose To estimate the diagnostic efficacy of saline-air hysterosalpingo–contrast sonography (SA-HyCoSy) compared with the modified hysterosalpingogram (mHSG) for confirmation of both coil location and tubal occlusion following hysteroscopic sterilization. Methods This study included 19 women who underwent both SA-HyCoSy and mHSG where 1 test was followed by the other. Sensitivity, specificity, and positive and negative predictive values for tubal occlusion against the mHSG were calculated for each fallopian tube by 2 independent interpreters. Interrater reliability was assessed using Cohen κ statistic. Procedure time and pain level by 11-point numeric rating scale of SA-HyCoSy and mHSG were also compared. Results Thirty-eight fallopian tubes were evaluated. Tubal occlusion was noted in 97.3% of tubes for both interpreters with the mHSG compared with 92.1% and 94.7% with SA-HyCoSy. The positive and negative predictive values for tubal occlusion were 100%/100% and 50%/33%, respectively, with an overall agreement of 97.4% and 95.7%, κ = 0.48, P < 0.01. Saline-air HyCoSy changed interpretation of coil insert location in 50% and 44.7% for each interpreter, being downgraded from optimal to satisfactory in 42.9% (9/21) and 36% (9/25) and upgraded to optimal in 58.8% (10/17) and 61.5% (8/13), respectively. There were no statistically significant differences in procedural time (7.5 vs 9.4 minutes, P > 0.05) or maximum pain scores (2.3 vs 3.1, P > 0.05) for the mHSG compared with SA-HyCoSy. Conclusions Our findings revealed a high degree of diagnostic accuracy with SA-HyCoSy for tubal occlusion, although coil location changed in nearly half of cases. Avoidance of radiation and patient convenience/compliance with SA-HyCoSy may outweigh the drawbacks.

Comparison of Effectiveness as well as Advantages and Disadvantages of Different Dimensions of Hysterosalpingo-Contrast Sonography for Diagnosis of Lesions Associated with Female Infertility

“…Thus, the correct and accurate assessment of tubal blockage is of great importance for the diagnosis and treatment of infertility. And for tubal obstruction assessment, both 3D-HyCoSy and 4D-HyCoSy also revealed superior results [ 15 , 16 ]. However, few studies have been conducted to compare the effectiveness of 3D-HyCoSy with 4D-HyCoSy.…”
