Definition / general
  • Most common congenital anomaly of the pancreas (3 - 10% of population); most patients are asymptomatic
  • Incomplete fusion of dorsal and ventral pancreatic buds / ducts causes separation of ventral and dorsal pancreas as a double pancreas
  • Two ductal systems drain separately to two duodenal papillae; may cause isolated dorsal or ventral pancreatitis (25%)
  • Not a risk factor for acute pancreatitis (Curr Gastroenterol Rep 2011;13:150) but may be risk factor for recurrent acute pancreatitis
  • Duct of Santorini provides main drainage
  • Diagnose by imaging studies such as ERCP
