经阴道彩色多普勒超声诊断原发性输卵管癌的临床价值

目的探讨分析经阴道彩色多普勒超声检查对原发性输卵管癌的诊断价值。方法对31例临床可疑为输卵管癌的病例,均经腹部超声检查与经阴道超声检查,分析比较两种方法的灵敏度、声像图及血流特征。结果经手术病理检查确诊17例中,经腹部超声诊断输卵管癌7例,灵敏度为41.18%,经阴道超声检查诊断输卵管癌14例,灵敏度为82.35%。两种方法诊断输卵管癌灵敏度比较差异有统计学意义(P<0.05)。声像图表现为三种类型,混合性、偏实性、类囊性,经阴道彩色多普勒超声在肿物实质性成分中均探及低阻血流,其阻力指数(RI)在0.18⁰.50之间。结论经阴道彩色多普勒超声诊断原发性输卵管癌灵敏度高于经腹部超声。

The value of transvaginal Color Doppler ultrasonography in diagnosis of primary fallopian tube carcinoma

Objective To explore the value of transvaginal Color Doppler ultrasonography in diagnosis of primary fallopian tube carcinoma. Methods Thirty-one cases with suspected fallopian tube carcinoma re-ceived transabdominal ultrasonography and transvaginal Color Doppler ultrasonography.The comparison of di-agnostic sensitivity,sonographic and blood flow features between the two test methods were performed. Re-sults Of 17 cases pathologically confirmed fallopian tube carcinoma,7 cases were confirmed by transabdominal ultrasound with sensitivity of 41.18%;14 cases were confirmed by transvaginal Color Doppler ultrasonography with sensitivity of 82.35%.Comparison of sensitivity between the two test methods showed statistically signif-icant difference （P〈0.05）.The three sonogram types of fallopian tube carcinoma were mixed,hemi-solid and cystoid.Transvaginal Color Doppler ultrasonography could obtain low-resistance blood flow the resist-ance index （RI）：0.18 - 0.50]while detecting tumor substantive components. Conclusion Transvaginal Color Doppler Sonography has higher diagnostic sensitivity for primary fallopian tube carcinoma than the transabdominal ultrasound.
