经阴道超声与宫腔镜对子宫内膜病变患者的诊断价值比较研究.

Objective: To investigate the clinical value of transvaginal ultrasonography and hysteroscopy in the diagnosis of en­dometrial lesions, to provide a theoretical basis for the clinical diagnosis of endometrial lesions. Methods: A total of 158 cases of suspected endometrial lesions, who were treated in Beijing First Flospital of Integrated Chinese and Western Medicine from March 2011 to March 2014, were selected and were detected by transvaginal sonography and hysteroscopy respectively. The diagnostic value of the two meth­ods was compared with the results of pathological diagnosis as the gold standard. Results: In the results of pathological examination, 143 patients were diagnosed as endometrial lesions, including 23 cases of endometrial hyperplasia (16.08%), 31 cases of endometrial polyps (21.68%), 24 cases of uterine submucosal myoma(16.78%), 19 cases of endometrial carcinoma(13.29%), 46 cases of chronic nonspecific endometritis(32.17%). The accuracy rate(94.41%) of hysteroscopy in the diagnosis of endometrial lesions was higher than that(81.12%) of transvaginal ultrasound, and the difference was significant (P<0.05); there were no statistical differences in the accuracy rate of the di­agnosis of submucosal myoma of uterus and endometrial carcinoma between transvaginal ultrasonography and hysteroscopy(P>0.05), and the accuracy rate of transvaginal ultrasound in endometrial hyperplasia, endometrial polyps and chronic nonspecific endometritis was lower than that of hysteroscopy, and the difference was statistically significant (P<0.05). The specificity of transvaginal ultrasonography in the diagnosis of endometrial lesions was lower than that of hysteroscopy (P<0.05), but there were no significant differences in sensitivity and AUC between the two methods (P>0.05). Conclusion: Transvaginal ultrasonography is a simple and effective method in diagnosis of endometrial diseases, and Flysteroscopy has higher accuracy and higher specificity in diagnosis of endometrial diseases.
