Congenital Choledochal Malformation - Current Concepts and Classification

Congenital choledochal malformations (a.k.a. choledochal cysts) are uncommon but must be considered in the differential diagnosis of conjugated jaundice in both infant and child. They are also an important cause of recurrent abdominal pain due to the presence of a common pancreatic biliary channel and predisposition to pancreatitis. We present an updated Kings College Hospital classification based on morphology derived from previous versions in the literature and review possible aetiological factors, current diagnostic and surgical strategies.
