Study on the diagnostic value of transvaginal ultrasound in the diagnosis of endometrial polypoid lesions

Abstract

Objective To explore the diagnostic value of transvaginal ultrasound in endometrial polypoid lesions. Methods Three hundred and forty-four cases with endometrial polypoid lesions diagnosed in Hankou Hospital of Wuhan from April 2012 to December 2016 were selected as the research objects.All patients underwent color Doppler ultrasonography before surgery.The image features were analyzed, and the specificity, sensitivity and accuracy of ultrasound diagnosis of endometrial lesions were analyzed and pathological results served as the gold standard. Results According to the postoperative pathological diagnosis, 142 cases were with endometrial polyps, Including 136 cases with simple endometrial polyps and 6 cases with endometrial polyps combined with endometrial carcinoma; 160 cases were diagnosed with endometrial polyps via transvaginal ultrasound, 38 cases were misdiagnosed (11.05%, 38/344), 20 cases were missed diagnosis(5.81%, 20/344), using the postoperative pathological results as the gold standard, the sensitivity of transvaginal ultrasonography in the diagnosis of endometrial lesions was 85.92% (122/142), the specificity was 81.19% (164/202), the accuracy was 73.14% (286/344), and the diagnostic accuracy of ultrasonography was consistent with the pathological diagnosis (Kappa>0.75). Conclusion The value of transvaginal ultrasound is to observe the presence of uterine lesions, the identification of benign and malignant lesions still need hysteroscopy examination.
