磁共振胰胆管成像评价成人胰胆管类型与胰腺炎发生率的关系

The Clinical Value of MRCP in Evaluating the Relationship of the Types of Pancreaticobiliary Ductal System and Pancreatitis in Adults

目的探讨磁共振胰胆管成像(MRCP)评价成人胰管的各种类型和胰胆管开口类型与胰腺炎发生率的关系。资料与方法搜集520例非胆管及胰腺肿瘤且胆管和胰管均被完整清晰显示的患者的常规MRCP资料,分析胰管的各种类型及胰胆管开口类型与胰腺炎发生率的关系。结果胰管有A、B、C、D 4个类型:A型最多见。C型和D型发生胰腺炎的概率高于A型和B型;胰胆管开口按其形状分为V、Y、U3种类型,"V"型和"Y"型最多见,且发生胰腺炎的概率高于"U"型。结论胰管的类型和胰胆管开口的类型与胰腺炎的发生率有密切的关系,常规MRCP重组图像结合原始图像对其评价具有很高的应用价值。

Objective To evaluate the relationship of the various types of the pancreatic ducts and pancreaticobiliary ducts with pancreatitis in adults using MRCP. Materials and Methods The conventional MRCP data of bile ducts and pancreatic ducts in 520 patients without turnouts were collected. The relationship of the types of pancreatic ducts and pan- creaticobiliary ducts with pancreatitis was analyzed. Results There were 4 types of pancreatic duct system in 520 patients and the A type was the most common type. Pancreatitis were more prevalent in type C and D ductal system than in type A and B and there was a statistically significant difference between them. There were 3 types of pancreaticobilialy duct system and the most common type were type ＂V＂ and ＂Y＂. Pancreatitis were more prevalent in type ＂V＂ and ＂Y＂ than in type ＂U＂ and there was a statistically significant difference between them. Conclusion The reconstructed images combined with original images of conventional MRCP is a powerful imaging method in analyzing the types of the pancreatic ducts and pancreaticobiliary ductal union in adults. Because of the close relationship between the types and pancreatitis, it could be a routine examination before ERCP to guide clinical diagnosis and therapy.
