阴道B超和宫腔镜对子宫内膜息肉的临床评估

目的探讨阴道B超和宫腔镜对子宫内膜息肉诊断的准确率。方法回顾性分析178例经临床拟诊子宫内膜息肉患者的临床资料，所有患者行阴道B超检查、宫腔镜检查和（或）镜下活检，以病理检查结果作为最后诊断的依据。将病理结果与B超诊断和宫腔镜诊断进行对比分析。结果B超诊断的敏感度、特异度、假阴性率、假阳性率及与病理诊断符合率分别为42．10％、97．14％、57．89％、2．86％及75．00％；宫腔镜诊断的敏感度、特异度、假阴性率、假阳性率及病理诊断的符合率分别为100．00％、97．14％、0、2．86％及90．48％。结论B超因其无创、简便、快捷可作为子宫内膜息肉的筛查手段，但漏诊率相对较高。宫腔镜诊断的符合率较高，可作为诊断子宫内膜息肉的最佳标准。

Clinical assessment of transvaginal B-ultrasonography and hysteroscopy in diagnosis of endometrial polyp

Objective To explore the accuracy rate of transvaginal B-ultrasonography and hysteroscopy in diagnosis of endometrial polyp. Methods The clinical data of 178 cases of suspected endometrial polyp was analyzed retrospectively. All of the cases were evaluated by transvaginal B-ultrasonography, hysteroscopy and （or） biopsy during hysteroscopy. The pathological examination results were taken as final diagnosis evidence. The diagnosis of transvaginal B-uhrasonography and hysteroscopy was compared with pathological examination. Results The sensitivity, specificity, false negative rate, false positive rate and coincidence rate of transvaginal B-uhrasonography with pathological examination in diagnosing endometrial polyp was 42.10%, 97.14% , 57.89%, 2.86% and 75.00%, respectively, while the sensitivity, specificity, false negative rate, false positive rate and coincidence rate of hysteroscopy with pathological examination was 100. 00%, 97.14%, 0, 2.86% and 90.48%, respectively. Conehtsion Being non-invasive, economic and simple, transvaginal B-uhrasonography can be taken as a screening method of endometrial polyp, but the missed diagnosis rate is relatively high. The hysteroscopy can be used as the best method in diagnosing endometrial polyp because of its higher coincidence rate.
