目的 探讨B超与MRI、宫腔镜联合诊断对宫腔占位性病变的临床意义。方法 选择2017年1月1日— 12月31日我院收治的108例疑似宫腔占位性病变患者为研究对象。所有患者均于宫腔操作前行阴道彩色多普勒超声(以下简称B超)检查、MRI检查及宫腔镜检查。与病理检查结果对比,分别分析其灵敏度、特异度。结果 108例患者中宫腔无病理变化者27例,子宫内膜息肉39例,子宫内膜增生27例,子宫黏膜下肌瘤10例,子宫内膜癌5例。B超、MRI、宫腔镜诊断灵敏度分别为72.84%、71.60%、75.31%,特异度分别为62.96%、85.19%、66.67%。B超+MRI诊断子宫黏膜下肌瘤和子宫内膜癌灵敏度100%,特异度分别为87.76%和99.03%。B超+MRI+宫腔镜诊断子宫内膜增生、子宫黏膜下肌瘤、子宫内膜癌灵敏度均为100%。结论 宫腔占位病变以良性病变居多,B超联合宫腔镜和MRI检查可提高诊断率。对子宫内膜癌高危人群应进行B超与MRI联合检查,宫腔镜定位活检仅在必要时实施。

Objective To explore the clinical significance of B-ultrasound, MRI and hysteroscopy in the diagnosis of uterine space occupying lesions. Methods 108 patients with suspected uterine space occupying lesions admitted to our hospital from January 1 to December 31 2017 were selected as the study objects. All patients were examined by vaginal color Doppler ultrasound, MRI and hysteroscopy before uterine operation. Compared with the results of pathological examination, the sensitivity and specificity were analyzed. Results Among the 108 patients, 27 had no pathological changes in uterine cavity, 39 had endometrial polyps, 27 had endometrial hyperplasia, 10 had submucous myoma, and 5 had endometrial cancer. The sensitivity of B-ultrasound, MRI and hysteroscopy were 72.84%, 71.60% and 75.31% respectively, and the specificity were 62.96%, 85.19% and 66.67% respectively. The sensitivity of B-ultrasound+MRI in the diagnosis of submucous myoma and endometrial carcinoma was 100% and the specificity was 87.76% and 99.03%, respectively. The sensitivity of B-ultrasound+MRI+hysteroscopy in the diagnosis of endometrial hyperplasia, submucous myoma and endometrial carcinoma was 100%. Conclusion Most of the uterine space occupying lesions are benign. B-ultrasound combined with hysteroscopy and MRI may improve the diagnosis rate. The high-risk group of endometrial cancer should be examined by B-ultrasound and MRI, and hysteroscopic biopsy would be performed only when necessary.
