[Histologic factors as elements of prognostic value in biliary atresia].
Biliary atresia (BA) is one of the biliary tree anomaly more frequent. Occurs in about 0.8 to 1/10.000 live births. BA is defined as a progressive biliary tree. The prognosis depends on the age of the diagnosis and precocity surgery. We present the results of a retrospective analysis of 71 RA carried out at the Garrahan Hospital from 1987 to 1993. 47 were female and 24 were male. Age ranged from 45 to 120 days of life. This study involved a consecutive series of 58 patients with histopathologic study of Porta-hepatis (PH) and liver biopsy obtained during the Kasai. The purpose of this study was to determine the value of histological factors as type of PH and hepatocytic giant cell transformation (GCT). 82.8% had favorable type of PH and the CCT was mild in 84.5%. 72.4% had bad outcome and was independent of the type of PH. Neither of them were statistically significant with survive and evolution. In our service neither PH non CGT were predictors of a bad outcome. There were good outcome in 27.5%, died 37.9% and 10.3% undergo liver transplantation. The precocity in a diagnosis and surgical procedure before two months of age are the most important factors in correlation with survival. Others immunomorphologic factors must be studied in BA that explained the etiopathogenic process. Orthotopic liver transplantation is the successful therapy in children with BA.
