[Congenital cholelithiasis].

The author screened 6000 newborns with ultrasound and two gallstones have found (in age 1 and 2 days). He found numerous floating echogenic spots in the gallbladder of three other newborns. The spots and one of two gallstones disappeared, the other gallstone did not changed during the first 6 months of life. The author thinks, the maternal predisposing factors have importance in the formation of intrauterine gallstones. These factors disappear after delivery and the connatal gallstones often disappear spontaneously. If they don't, the author thinks it worthy to try to resolve them with ursodeoxycholate.
