Abstract

Objectives: The study aim was to evaluate the diagnostic performance of the uterine sliding sign in predicting deeply infiltrating endometriosis in the setting of non-physician sonographers performing but not interpreting the maneuver. The impact of uterine sliding sign has not been previously demonstrated in this practice setting. Methods: Physicians' remote interpretations of transvaginal ultrasound examinations in 2016, before uterine sliding sign, were compared to examinations in 2019 after addition of uterine sliding sign to determine the diagnostic rates. Surgical and histopathological results were reviewed to determine sensitivity and specificity of the respective exam techniques. Results: Two hundred eighty-five transvaginal ultrasounds were performed in 2016 and 390 sliding sign ultrasounds in 2019. The number of deeply infiltrating endometriosis cases identified increased significantly from 2% to 6% during the study period (chi-square, Fisher's exact test p =.012). The sensitivity and specificity of routine pelvic sonography for detecting deeply infiltrating endometriosis improved from 36%/94% to 68%/98%. Conclusions: Uterine sliding sign videos should be included in the standard sonographic protocol for patients presenting with chronic pelvic pain, endometriosis history, or sonographic evidence of endometriosis in the setting of physicians interpreting sonographic images obtained by non-physicians.
