目的 :探讨CT诊断胰胆管合流异常的可能性。方法 :结合正常胆管、胰管汇合部解剖 ,复习 3例胰胆管合流异常病人的CT表现。结果 :正常情况下 ,胆总管与主胰管在十二指肠壁内汇合。胰胆管合流异常时 ,可见两者在十二指肠壁外直接汇合 ,此为直接征象 ;或是胆总管与主胰管先呈“双管征”样排列 ,在其后的断层图像上则成为一个管道 ,虽未看到直接汇合 ,但实际上已经汇合 ,此为间接征象。结论 :CT同样可以诊断胰胆管合流异常
Objective: To explore the possibility of CT diagnosis of pancreaticobiliary duct anomalies. Methods: CT findings of 3 cases of pancreaticobiliary duct anomalies were reviewed according to anatomy of normal bile duct and pancreatic duct junction. Results: Under normal circumstances, the common bile duct and the main pancreatic duct confluence in the duodenal wall. Pancreatic duct anomalies, we can see both direct confluence outside the duodenum, this is a direct indication; or the common bile duct and the main pancreatic duct was “double-tube sign” -like arrangement in the subsequent tomographic To become a pipeline, although we have not seen the direct convergence, have actually converged, which is an indirect symptom. Conclusion: CT can also diagnose pancreaticobiliary duct anomalies
