目的探讨彩色多普勒超声在肝外胆管癌诊断中的价值。方法利用彩色多普勒超声对35例诊断为肝外胆管癌图像特征进行分析,并与病理结果进行比较。结果在彩色多普勒超声术前诊断的35例肝外胆管癌中,术后病理诊断肝外胆管癌31例,诊断符合率为88.6%。术后病理诊断肝外胆管泥沙样结石3例,占8.7%。术后病理诊断肝外胆管炎1例,占2.9%。结论彩色多普勒超声是诊断肝外胆管癌的一种有效方法。
Objective To investigate the value of color Doppler ultrasonography in the diagnosis of extrahepatic cholangiocarcinoma. Methods The color characteristics of 35 cases diagnosed as extrahepatic cholangiocarcinoma were analyzed by color Doppler ultrasound and compared with the pathological results. Results Among 35 cases of extrahepatic cholangiocarcinoma preoperatively diagnosed by color Doppler sonography, 31 cases were diagnosed as extrahepatic cholangiocarcinoma by pathology, the coincidence rate was 88.6%. Postoperative pathological diagnosis of extrahepatic bile duct sediment-like stones in 3 cases, accounting for 8.7%. Postoperative pathological diagnosis of extrahepatic cholangitis in 1 case, accounting for 2.9%. Conclusion Color Doppler ultrasound is an effective method for the diagnosis of extrahepatic cholangiocarcinoma.
