Choledocholithiasis in a 4-month-old infant.

Cholelithiasis is increasingly being diagnosed in newborns and infants because of the more frequent use of abdominal ultrasound. However, common bile duct stones causing obstruction or symptoms in infancy are exceedingly rare and are not often reported in the literature. We report the successful treatment of symptomatic choledocholithiasis in a 4-month-old patient with endoscopic retrograde cholangiopancreatography and endoscopic sphincterotomy.
