The Clinical Significance Study Of Pancreaticobiliary Anatomy By Magnetic Retrograde Cholangiopancreatography

Objective:MRCP study of pancreaticobiliary junction anatomy and explore the classification and incidence of pancreaticobiliary anatomy,preliminary study on the feasibility of MRCP to diagnose the PBM.Methods:Statistical 297 patients who had underwent the examination of magneticresonance cholangiopancreatography for pancreaticobiliary diseases in our hospital,and analysis the length of common channel,the time go to the hospital,the relationship between the type of pancreaticobiliary and the disease.Results:The bile common duct and canals of wirsung were detected clearly in 228 patients and were not detected in 69 patients.In 228 patients,The types of pancreaticobiliary ductal union were classified into normal confluence and abnormal confluence,the mormal confluence inclode “Y”,“V”and “U”type.known as "Y" in 58 specimens(25.43%),"V" in 62 specimens(27.19%,"U" in 69specimens(30.26%)and pancreaticobiliary maljunction type in 39 specimens(17.11%).The length of the common channel of pancreaticobiliary maljunction type confluence is 13.63 plus or minus 4.55,and the length of the abnormal confluence common channel is 6.41 plus or minus 1.51.There are significant differences between the two,P < 0.05.There is a significant difference between normal union and abnormal union in the number of go to the hospital,P <0.05.Normal confluence and abnormal confluence of pancreatic cancer,pancreatitis,choledochocysts in the biliary pancreatic diseases accounted for a significant difference in the proportion,P<0.05.Conclusion: MRCP can preliminary diagnosis of PBM by observe the anatomical features of the pancreaticobiliary junction and measure the length of the common channel,however,other tests are needed to confirm the PBM.
