Abstract: | A retrospective review of the abdominal CT scans of 26 children with extrahepatic biliary atresia was performed, and the results
were correlated with available surgical and pathologic data. Associated congenital anomalies or acquired abnormalities were
identified in these patients. Congenital anomalies included polysplenia, venous anomalies and bowel stenosis. Acquired abnormalities
developed secondary to cirrhosis, portal hypertension, intrahepatic biliary duct dilatation, and hepatic ischemia. Despite
frequent episodes of ascending cholangitis in these children, no hepatic abscesses were identified by CT or by pathologic
examination. In conclusion, abdominal CT scanning of children with extrahepatic biliary atresia can define congenital and
acquired abnormalities and provide important anatomic data for the surgeons before liver transplantation. |
