BACKGROUND: There is no good prognostic indicator for biliary atresia (BA). We reviewed liver biopsies taken during the initial procedure to find a prognostic marker. METHODS: Thirty-two BA cases underwent Kasai operation from 1976 to 2009. We compared two groups at 1, 3, and 9 years. Group A required liver transplantation or died. Group B survived with their native liver. Biopsies were analyzed for liver fibrosis, portal-central vein bridging (P-C bridging), ductal plate malformation (DPM) and the number of the bile ducts in portal canal/measured surface area of the portal canal (BDP ratio). Statistical comparisons of the multiple data were evaluated by Mann-Whitney U test, Student's t test and Pearson's Chi-square test. Regression analysis with P < 0.05 was considered significant. RESULTS: BDP ratios (/mm(2)) were 2.4 ± 1.5 in Group A1 (n = 9) vs 4.6 ± 2.4 in Group B1 (n = 23) (P = 0.01); 2.6 ± 1.4 in Group A3 (n = 14) vs 5.1 ± 2.5 in Group B3 (n = 18) (P < 0.01), 3.0 ± 2.2 in Group A9 (n = 15) vs 4.9 ± 2.5 in Group B9 (n = 15) (P < 0.05). There was no significant difference in any other finding. CONCLUSION: The BDP ratio is a sound prognostic indicator in BA.
