Abstract:
Objective To study the relevance of 1iver fibrosis at Kasai procedure with age, degree of pathological changes of liver tissue, header bile ductuler proliferation and pathological feature of portal fibrous tissue in biliary atresia patients. Methods From January 2013 to June 2016, 48 biliary atresia patients accepted Kasai procedure, and liver tissue biopsy and portal fibrous tissue excision was done. Level of liver fibrosis was evaluated under microscope using Masson trichrome staining and HE staining, and extent of ductular reaction was evaluated using CKl9 immunohistochemistry staining with image analysis technology. Based on classification of Okamoto severity degree of liver fibrosis, forty eight patients were divided into two groups:low-grade liver fibrosis group (23 patients)and severe liver fibrosis group (25 patients). The relevance of age at Kasai procedure, liver pathological changes, header bile ductuler proliferation, portal fibrous tissue in volume and bile ductuler proliferation, inflammation reaction with severity degree of liver fibrosis was analyzed with SPSSl6.0 software statistically. Results Age of severe 1iver fibrosis group at Kasai procedure were 38- 89 d, and the mean age was (62.64 ± 14.92) d. Age of low-grade 1iver fibrosis group were 18- 92 d, and the mean age was (53.13 ± 16.89) d. There was significant difference (t=2.071, P=0.044). Mean number of patients with header bile ductuler proliferation at Kasai procedure in severe 1iver fibrosis group and low-grade 1iver fibrosis group were (17.28 ± 4.31) cases and (11.39 ± 4.00) cases, and there was significant difference (t=4.900, P=0.000). There was significant difference in degree of hepatocellular pathological changes at Kasai procedure between groups (χ2 =4.691, P=0.030). There were no significant differences in the volume of portal fibrous tissue in volume (t=0.276, P=0.784), portal bile ducts proliferation (t=0.53, P=0.60) and inflammation reaction (χ2=3.074, P=0.080) between groups. Conclusions There is significant relevance between the degree of 1iver fibrosis in biliary atresia patients at Kasai procedure and age, level of hepatocellular pathological change and degree of header bile ductuler proliferation , The more older the age, the more sever the hepatocellular pathological change and the bile ductuler proliferation, the more sever the liver fibrous.
