Abstract: Background: Congenital pancreaticobiliary malformations are sometimes associated with acute or chronic pancreatitis and biliary carcinoma. Currently, MRCP is one of the first choices for investigating and diagnosing pancreaticobiliary diseases noninvasively. We compared the accuracy of conventional MRCP and ERCP in making the diagnosis of congenital pancreaticobiliary malformations.Methods: In patients with pancreas divisum (n = 17), pancreaticobiliary maljunction (n = 12), choledochocele (n = 2) and annular pancreas (n = 1) who underwent both ERCP and MRCP, the diagnostic accuracy and findings on MRCP were compared with those on ERCP.Results: Of the 32 patients with congenital pancreaticobiliary malformations diagnosed on ERCP, 23 (72%) patients could also be diagnosed on MRCP. Complete pancreas divisum was diagnosed in 73% on MRCP based on the finding of a dominant dorsal pancreatic duct crossing the lower bile duct and emptying into the duodenum without communicating with the ventral pancreatic duct. Pancreaticobiliary maljunction was diagnosed in 75% on MRCP based on the finding of an anomalous union between the common bile duct and the pancreatic duct, as well as the existence of a long common channel.Conclusions: Conventional MRCP is a useful, noninvasive tool for diagnosing congenital pancreaticobiliary malformations; and the diagnostic accuracy can be increased with 3D-MRCP or dynamic MRCP with secretin stimulation. |
