经阴道三维超声诊断子宫内膜癌的探讨

Study of three-dimensional transvaginal sonography in diagnosis of uterus endometrial carcinoma and the depth of myometrial invasion

目的探讨经阴道三维超声(3-DTVS)诊断子宫内膜癌及肌层浸润的价值。方法收集2003年4月～2005年4月在我院经手术治疗的子宫内膜癌患者72例。其中,术前64例(3-DTVS组)应用3-DTV多平面和血管成像技术以及体积测量功能诊断子宫内膜癌及肌层浸润深度进行评估;25例(MRI组)经核磁共振(MRI)检查为对照组,以手术后病理结果判断符合率,对比两组诊断子宫内膜癌及其肌层浸润情况。结果经3-DTVS诊断子宫内膜癌的符合率为89.1%,判断肌层浸润的符合率为77.1%。应用3-DTVS与MRI诊断子宫内膜癌及肌层浸润准确率两组间无显著性差异(P>0.05)。结论3-DTVS在诊断子宫内膜癌及肌层浸润深度有诊断价值。

Objective To evaluate three - dimensional transvaginal sonography （3 - DTVS） in diagnosis of uterus endometrial carcinoma and depth of myometrial invasion. Methods Seventy - two patients with endometrial carcinoma confirmed by postoperative pathology were admitted in our hospital. Uterus endometrial carcinoma and depth of myometrial invasion were diagnosed by multiplanar mode, glass body mode and volume measurement base on 3 -DTVS in 64 patients. The patients who underwent MRI before operation served as control group （n= 25）. The preoperative measurements of 3 - DTVS and MRI were compared with the postoperative histopathological finding. Results Diagnosis of uterus endometrial carcinoma was made by 3 - DTVS in 89.1% of the testing group, and accuracy of the depth of myometrial invasion was 77.1%. No differences were found between the 3 - DTVS and MRI group. Conclusion 3 - DTVS is valuable in diagnosis of endometrial carcinoma and detection of the depth of myometrial invasion.
