Cholelithiasis with common bile duct obstruction in a 20-week-old infant.

Formation of bile calculi in the common bile duct is a rare event in early infancy. The following article describes the case of a 20-week-old infant with anal atresia and a deep rectovaginal fistula who presented with recurrent jaundice due to a single calculus in the common bile duct that led to intermittent obstruction of the papilla Vateri. Diagnosis was proven by endoscopically performed retrograde cholangiography and the concretion was successfully removed after transduodenal papillotomy using a Dormia basket.
