[Congenital cystic transformation of the common bile duct in children]. / Vrozhdennaia kistoznaia transformatsiia obshchego zhelchnogo protoka u detei.

By now the world literature counts 955 observations on congenital cystic enlargement of the common bile duct. The authors add 14 own observations of this rather rare pathology. Preoperative diagnosis is still difficult. The intravenous cholegraphy remains the best diagnostic procedure. The choledochocystoduodenostomy is justified by its usefulness and is the most frequently used. The late results of the treatment are good. An unfavourable prognosis is present only in cases with preoperative chronic hepatitis, cholangitis or pancreatitis, as these diseases are likely to aggravate later on.
