title: The changing aspects of cholelithiasis in children through a sonographic study.
abstract: Ultrasonography has made the study of the biliary tract easier. This may account for an apparent increase in the incidence of cholelithiasis in children. Twenty-nine cases of biliary stones, mostly gallstones, were seen in a 3 year period. More than half of the cases were secondary to a definite cause, among which the interruption of the enterohepatic circulation of bile salts should be emphasized. The etiological factors of biliary stones and biliary sludge appeared identical in our material.
