目的探讨彩超在胆管细胞癌诊断及鉴别诊断中的价值。方法对本院28例肝内胆管癌患者进行超声及手术病理诊断回顾性对比分析。结果发现21例患者肝内表现为沿胆管走行不规则条索状强回声,7例声像图表现为胆管不规则增厚,管腔狭窄。进行彩色多普勒检查,其中有8例,可检出少许点状血流信号。结论肝内胆管癌的声像图表现与其他肝内占位具有明显区别,综合分析超声征象并密切结合临床可以提高诊断准确率,彩超是诊断胆管癌首选的影像学方法。
Objective To investigate the value of color Doppler ultrasound in the diagnosis and differential diagnosis of cholangiocarcinoma. Methods A retrospective analysis of 28 cases of intrahepatic cholangiocarcinoma in our hospital by ultrasonography and pathological diagnosis. The results showed that 21 cases of liver showed irregular bar-like echo along the bile duct echoes, 7 cases showed irregular bile duct thickening, stenosis. Color Doppler examination, of which 8 cases, can detect a little punctate blood flow signal. Conclusion Ultrasonography of intrahepatic cholangiocarcinoma shows obvious difference from other intrahepatic space occupying lesions. Comprehensive analysis of ultrasound signs and close clinical combination can improve the accuracy of diagnosis. Color Doppler ultrasound is the imaging method of choice for diagnosis of cholangiocarcinoma.
