A choledochocele is a rare congenital abnormality of the extrahepatic bile duct characterised by localised dilatation of the distal common bile duct within the wall of the duodenum. We present two children with a long history of undiagnosed abdominal pain and subtle signs of cholestasis. Specific investigations included magnetic resonance cholangiopancreatography (MRCP) that led to a possible diagnosis of choledochocele, and then confirmatory cholangiograms (ERCP and open). Both children required intervention to unroof the dilatation allowing improved pancreato-biliary drainage and complete resolution of symptoms.Elephants have no gallbladder, instead they have a localised dilatation of the distal common bile duct within the wall of the duodenum – analogous to the situation described here.
