Congenital cystic malformation of the bile ducts: report of a case and review of related literature.
A 20-year-old woman had a cyst of the proximal part of the common bile duct and a cyst of the left hepatic duct; these lesions were diagnosed preoperatively by intravenous cholangiography and successfully operated upon. At the time of writing, she has been followed up for one year.Congenital defects in the biliary system are rare and, in a review of the literature, only two cases were found similar to this one. It is generally accepted that these lesions are congenital, but the exact pathogenesis is unknown.Alonso-Lej, Rever and Pessagno(2) reviewed the literature in 1959 and found 403 authentic congenital cysts of the hepatic ducts. The most common congenital defect is a single choledochal cyst of the lower end of the common bile duct. Pain, jaundice and tumour are the main symptoms.Until the advent of intravenous cholangiography, these lesions were seldom recognized preoperatively. Means of operative repair as well as complications and prognosis are reviewed.
