[Bile duct stricture in childhood. A diagnostic challenge (author's transl)].

5 cases of biliary stricture, 3 congenital, 1 malignant and 1 blunt traumatic are reported in 3 infants and 2 children. Jaundice is present in 4 patients only and is delayed in 2. Alkalin phosphatases are constantly elevated but ultrasound studies negative in 3 patients. Diagnosis was made by percutaneous cholangiography in 2 and per-operative cholangiogram in 3. Roux en Y hepaticojejunostomy is successfully performed in 4. Bile duct stricture is a rare cause of cholestatic jaundice in childhood and an even rarer sequela of blunt trauma. This series demonstrates the usefulness of percutaneous transhepatic cholangiography, more accurate than ultra-sonography in investigating cholestasis in childhood.
