摘要
目的 研究胰胆管扩张对胰腺癌与慢性胰腺炎的诊断意义。材料与方法 回顾性分析 49例胰腺癌和 3 6例慢性胰腺炎的CT资料。结果 胰腺癌组主要特征包括 :( 1)胰管扩张多呈平滑状 ,并多在胰头肿块处截断 ( 16例 ,占 80 % ) ;( 2 )扩张的胆总管多呈突然截断 ( 2 7例 ,占 87.1% ) ,部分可见肝内、外胆管扩张 ( 19例 ,占 3 8.8% ) ;( 3 )双管征 ( 19例 ,占 3 8.8% )。慢性胰腺炎组的主要特征为 :( 1)胰管扩张多呈不规则型并贯通病变区 ( 7例 ,占 77.8% ) ,部分可见沿胰管分布的钙化或结石 ( 5例 ,占 13 .9% ) ;( 2 )扩张的胆总管由上至下逐渐变细 ( 7例 ,占 10 0 % )。
Objective To study the diagnostic value of pancreaticobiliary duct dilation in pancreatic carcinoma and chronic pancreatitis.Materials and Methods CT findings of pancreatic carcinoma in 49 cases and chronic pancreatitis in 36 cases were retrospectively analyzed.Results In 49 patients with pancreatic carcinoma the following features were observed: (1) dilated pancreatic duct, with smooth and regular caliber (n=16, 80%); (2) dilated common biliary duct, ruptured suddenly in most cases (n=27, 87.1%), with intra and extra hepatic cholangiectasis (n=19, 38.8%); (3) double duct sign (n=19, 38.8%). In 36 patients with chronic pancreatitis the following signs were seen: (1) irregularly dilated pancreatic duct, running through the lesion (n=7, 77.8%) with calcifications and calculus along the pancreatic duct (n=5, 13.9%); (2) dilated common biliary duct, tapering from above downward (n=7, 100%).Conclusion CT characteristics of pancreaticobiliary duct dilation are very helpful in diagnosing pancreatic carcinoma and in differentiating cancer with chronic pancreatitis.
