Abstract
Hepatocellular injury including multinuclear changes are common histological features in biliary atresia (BA), as well as in neonatal hepatitis. To date, however, no reports have examined how those findings correlate with the prognosis of BA. We clarified the clinical implications of hepatitis-related changes in BA on histological analysis. We retrospectively reviewed 34 cases of BA treated over the past 30 years at Ibaraki Children's Hospital. Liver biopsy specimens during Kasai procedures were evaluated for hepatocyte multinuclear change, ballooning, and acidophilic body, hereby defined as hepatitis-like findings (HLF). Each finding was semi-quantitatively scored as 0-2, and their sum was defined as the HLF score, ranging from 0 to 6. We examined the correlation between HLF score and total bilirubin (T-Bil), direct bilirubin (D-Bil), and other liver function test results at the Kasai procedure, as well as 1 week, and 1, 3, and 6 months after the Kasai procedure. Subsequently, HLF score was compared between native liver survivors (NLS; n = 16) and non-NLS (n = 18) for long-term analyses. Hepatitis-like findings score except for aspartate aminotransferase (AST), had no correlation with the preoperative data. HLF score was posit...Continue Reading
