"with biliary dilatation (~ 80%): 50% diagnosed in children, often associated with stricture of the hilar duct and tend to have a higher incidence of symptoms"
"type A (stenotic type): dilatation of the common bile duct upstream of a stenotic segment of the distal common bile duct, which joins the common channel"
"type B (non‐stenotic type): nonstenotic distal common bile duct smoothly joins the common channel; no localised dilatation of the common channel"
"type C (dilated channel type): narrow distal common bile duct joins dilated common channel"
"type D (complex type): complex maljunction associated with annular pancreas, pancreas divisum, or other complicated duct systems"
"The Japanese Study Group on Pancreaticobiliary Maljunction (JSPBM) proposed the following classification in 2015 5,9:"
"ERCP"
"An intrabiliary amylase level more than 8000 UI/L within the bile duct and gallbladder obtained endoscopically (ERCP) or percutaneously suggests reflux of pancreatic juice through an anomalous pancreaticobiliary junction and shows a positive predictive value and a specificity of more than 90 % 6."
"An intrabiliary amylase level more than 8000 UI/L within the bile duct and gallbladder obtained endoscopically (ERCP) or percutaneously suggests reflux of pancreatic juice through an anomalous pancreaticobiliary junction and shows a positive predictive value and a specificity of more than 90 % 6."
"In patients with a short common channel, direct cholangiography (e.g. ERCP) can be effective in the assessment of pancreaticobiliary junction incompetence."
"MRCP is the gold standard of diagnosis and is superior to ERCP in depicting biliary anatomy, including the intrahepatic bile duct."
"Drip-infusion cholangiography CT involves the injection of intravenous biliary contrast agent and can well-delineate biliary anatomy and is less invasive than ERCP."
