Choledocholithiasis in infancy.

Three cases of choledocholithiasis presenting with obstructive jaundice in infancy are reported. Ultrasonography demonstrated a grossly dilated common bile duct in all three cases. It failed, however, to demonstrate the calculi that were situated at the distal end of the common duct. Percutaneous transhepatic cholangiography was valuable in one patient in outlining the biliary tract and in identifying the cause of the obstruction. Endoscopic retrograde cholangiopancreatography (ERCP) was employed in a child, aged three years, in whom it was possible to proceed to endoscopic sphincterotomy with clearance of the common duct. In small infants, transduodenal sphincteroplasty would appear to be the procedure of choice.
