摘要
目的分析肝外胆管梗阻诊断中MRCP(磁共振胆胰管造影)的临床应用价值。方法 2016年7月-2018年9月,于该院诊治的肝外胆管梗阻患者中选取107例,对其MRCP检查临床资料进行回顾性分析,对比良性与恶性肝外胆管梗阻的MRCP表现差异。结果良性肝外胆管梗阻诊断中,MRCP的定位准确率为100.00%,定性准确率为98.67%;恶性肝外胆管梗阻诊断中,MRCP的定位准确率为100.00%,定性准确率为90.63%;良性肝外胆管梗阻患者管腔主要呈现为均匀扩张现象,管壁则均匀增厚,有"鸟嘴样"改变出现在断端;恶性肝外胆管梗阻患者管腔主要呈现为不均匀的对称扩张现象,突然之间截断或者狭窄,管壁则不均匀增厚,有"双管截断征"出现。结论肝外胆管梗阻诊断中MRCP具有良好的定位准确性与定性准确性,应用价值显著。
Objective To analyze the clinical value of MRCP(magnetic resonance cholangiopancreatography) in the diagnosis of extrahepatic biliary obstruction. Methods A total of 107 patients with extrahepatic bile duct obstruction admitted to our hospital from July 2016 to September 2018 were selected. The clinical data of MRCP examination were retrospectively analyzed, and the MRCP manifestations of benign and malignant extrahepatic bile duct obstruction were compared. Results In the diagnosis of benign extrahepatic bile duct obstruction, the positioning accuracy of MRCP was100.00% and the qualitative accuracy was 98.67%. In the diagnosis of malignant extrahepatic bile duct obstruction, the positioning accuracy of MRCP was 100.00% and the qualitative accuracy was 90.63%. In patients with benign extrahepatic bile duct obstruction, the lumen mainly appears as a uniform expansion phenomenon, the wall of the tube is evenly thickened, and a "bird’s beak" change occurs at the broken end. In patients with malignant extrahepatic bile duct obstruction, the lumen appears mainly as a non-uniform symmetrical expansion phenomenon. Suddenly, it is cut off or narrowed, and the wall of the tube is unevenly thickened. There is a "double tube truncation sign". Conclusion MRCP has good positioning accuracy and qualitative accuracy in the diagnosis of extrahepatic bile duct obstruction,which is worthy application.
