MRCP观察胰胆管合流解剖及意义
The study of pancreaticobiliary anatomy through magnetic resonance cholangiopancreatography
目的 通过MRCP观察胰胆管合流的解剖，探讨胰胆管合流异常(Pancreaticobiliary maljunction, PBM)的诊断。 方法 搜集MRCP 954例，观察胰胆管汇合情况及其与十二指肠壁的关系。 结果 胆总管和胰管均显影的841例，无法观察胰胆管汇合的113例。显影良好的841例中，胰胆管的汇合存在U、V、Y和合流异常4种胰胆管合流方式；其中Y型356例（42.33%，），V型242（28.78%），U型165（19.62%），疑似PBM 78（9.27%）。 结论 MRCP可观察胰胆管解剖，确诊PBM还需要其他辅助检查。
Objective To investigate the pancreaticobiliary anatomy through magnetic resonance cholangiopancreatography. Methods 954 patients who had underwent the examination of magnetic resonance cholangiopancreatography were studied to investigate the pancreaticobiliary anatomy. Results The bile common duct and canals of wirsung were detected clearly in 841 patients and were not detected in 113 patients. In 841 patients, The types of pancreaticobiliary ductal union were classified into four types , known as "Y" in 356 specimens(42.33%), "V" in 242 specimens（28.78%,"U" in 165 specimens（19.62%） and pancreaticobiliary maljunction type in 78 specimens（9.27%）. Conclusions The pancreaticobiliary anatomy can be observed by magnetic resonance cholangiopancreatography, however, it cannot make a definite diagnosis to pancreaticobiliary maljunction.
