磁共振胰胆管成像在婴幼儿胆管疾患中的应用

Application of Magnetic Resonance Cholangiopancreatography in Children′s Biliary Pathology

目的探讨磁共振胰胆管成像（MRCP）在婴幼儿胆管疾患的诊断价值。方法搜集本院2004年4月-2005年9月行MRCP检查并经手术病理证实的47例婴幼儿胆管疾患的病例进行回顾性分析。结果胆管闭锁22例;胆汁黏稠综合征1例;先天性胆管扩张症24例,其中合并胰胆管合流、胆石症、胆泥沉积症各1例。MRCP能直接显示胆管树及胰管的形态,明确胆管闭锁、扩张、梗阻的部位、范围,定性诊断率达95.6%。结论MRCP不用对比剂,无损伤,在婴幼儿胆管疾患的诊断中敏感性及定性诊断率高,是首选诊断方法。

Objective：To discuss the application of magnetic resonance cholangiopancreatography （MRCP） in children＇s biliary pathology. Methods：47 cases who underwent MRCP examination in our hospital from April 2004 to September 2005 and were proved by operation to have biliary tract diseases were reviewed retrospectively. Results： There were 22 patients diagnosed with biliary atresia, 1 patient with choler dence disorder,and 24 patients with congenital biliary dilatation of which 1 patient complicated with pancreaticobiliary maljunction, 1 patient with cholelithiasis and 1 patient with biliary sludge. Conclusion： MRCP can show the bile duct tree and pancreas duct immediately and make sure of the position of bile duct atresia,dilatation or obstruction. MRCP doesn＇t need any contrast medium and causes no trauma. It is the method of first choice in diagnosing children＇s biliary pathology with high accuracy.
