[Cystic dilatation of common bile duct. Observation of a case (author's transl)]

Radiographic demonstration of a common bile duct cyst in a twenty-seven--year-old woman, treated by short-circuit to a loop of jejunum arranged to form a "Y" with an anti-reflux anastomosis at the foot of the loop. Evaluation of iconography during surgery would support an aetiopathogenetic theory according to which pancreatic reflux into the bile ducts would result from the ectopic implantation of the choledochus in Wirsung's duct.
