Studies on Formation of Bile Duct Stones Due to Congenital Malformation of the Biliary Tract

Part II Choledocholithiasis Related to Congenital Cystic Dilatation of the Common Bile Duct

Abstract

Sixty-seven patients with the adult type of congenital cystic dilatation of the common bile duct (Alonso-Lej's Type I) were studied. Fifty-seven of them had gallstones, which were found in about half of patients below 30 years old and in most of those over 30. Gallstones were found almost in common bile duct and/or intrahepatic bile duct. We knew that congenital cystic dilatation of the common bile duct was closely related to the formation of primary choledochus stone.
On the surgical treatment of choledocholithiasis due to this disease, cholecystectomy, choledocholithotomy and choledochocysto jejunostomy with Roux-en-Y anastomosis or choledochocystoduodenostomy were most effective for this malady in our studies.
