AI Article Synopsis
- The Diagnostic Criteria for Pancreaticobiliary Maljunction were published by the Japanese Study Group in 2014, establishing standards for diagnosing conditions related to the bile duct.
- The criteria define congenital biliary dilatation as a malformation involving the dilation of the extrahepatic bile duct and its association with pancreaticobiliary maljunction, with specific imaging requirements for diagnosis.
- A thorough distinction must be made between congenital conditions and acquired issues like obstructions from gallstones, emphasizing the first comprehensive diagnostic guidelines established in Japan in 2015.
Article Abstract
Background: The Diagnostic Criteria for Pancreaticobiliary Maljunction 2013 were published by the Japanese Study Group on Pancreaticobiliary Maljunction (JSGPM) in 2014. The committee of JSGPM for diagnostic criteria for pancreaticobiliary maljunction has established the standard diameter of the bile duct, and a definition of dilatation of the bile duct was proposed in 2014.
Methods: The committee of JSGPM prepared the diagnostic criteria for congenital biliary dilatation in 2014, and a final revised version was approved in 2015.
Results: Congenital biliary dilatation is defined as a congenital malformation involving both local dilatation of the extrahepatic bile duct, including the common bile duct, and pancreaticobiliary maljunction. However, cases associated with intrahepatic bile duct dilatation can also be included. Various kinds of pathological conditions can occur on hepatobiliary systems and pancreas by bile duct dilatation and pancreaticobiliary maljunction. For a diagnosis of congenital biliary dilatation, both abnormal dilatation of the bile duct and pancreaticobiliary maljunction must be evident by either imaging test or anatomical examination. Acquired or secondary dilatation of the bile duct by obstruction due to biliary stones or malignancy should be strictly excluded.
Conclusion: Diagnostic criteria for congenital biliary dilatation 2015 were established from Japan representing a world first.
