Choledocholithiasis in a premature neonate.

Choledocholithiasis in neonates and infants has been reported only rarely. Infants with complications of prematurity are more predisposed to development of biliary calculi. With the current widespread use of diagnostic ultrasonography, more neonates may be found to have gallstones and common bile duct stones. We describe a case of choledocholithiasis and cholelithiasis in a premature neonate successfully treated by surgical placement of a cholecystotomy tube and irrigation of the biliary system.
