多普勒超声相较二维超声在肝外胆管癌诊断中的优势分析

目的：分析多普勒超声相较于二维超声在肝外胆管癌定性、定位诊断中的优势。方法收集2013年1月－2015年5月经病理证实的60例肝外胆管癌患者的二维超声和彩色多普勒超声检查结果，比较两者对肝外胆管癌检出率、误诊率、漏诊率及定位诊断上的差异。结果彩色多普勒和二维超声超声的肝外胆管癌检出率、误诊率及漏诊率分别为76．3％、7．0％、16．7％和73．3％、10．0％、16．7％，前者相较于后者可显著降低肝外胆管癌的误诊率，两者在检出率、漏诊率及定位诊断上无显著差异。结论彩色多普勒超声对肝外胆管癌的定性诊断效能显著高于二维超声，但在定位诊断上相较于后者无明显优势。

The advantages of color doppler ultrasound compared to two-dimensional ultrasound in the diagnosis of ex-trahepatic cholangiocarcinoma

Objective To analyze the advantages of color doppler ultrasound compared to conventional two?dimensional ultra?sound in the qualitative and localization diagnosis in extrahepatic cholangiocarcinoma. Methods Collected the results of two?dimen?sional ultrasound and color doppler ultrasound of 60 patients who had been confirmed by pathologically with extrahepatic cholangiocarci?noma from January 2013 to May 2015 in our hospital, and to compare the difference of the two inspection methods at the detection rate, misdiagnosis rate and missed diagnosis rate and localization diagnosis in extrahepatic cholangiocarcinoma. Results The detection rate, misdiagnosis rate and missed diagnosis rate of color doppler ultrasound and two?dimensional ultrasound respectively were 76.3%,7.0%, 16.7% and 73.3%,10.0%,16.7%. Color doppler ultrasound could significantly reduce the misdiagnosis rate of extrahepatic cholangio?carcinoma. There were no difference of detection rate, missed diagnosis rate and localization diagnosis between two methods. Conclusion The performance of color doppler ultrasound in the qualitative diagnosis of extrahepatic cholangio carcinoma was signifi?cantly higher than two?dimensional ultrasound, but there was no significant difference in the localization diagnosis.
