Biliary atresia is a category of disease caused by biliary cirrhosis due to progressive fibro-inflammatory obstruction of extrahepatic and intrahepatic bile ducts, and eventually progresses into liver failure. It is a common indication for liver transplantation in children. In this article, the pathogenesis, diagnosis of biliary atresia, timing, procedures and postoperative complications of liver transplantation were illustrated. Meantime, current status and development of pediatric liver transplantation were discussed.

Objective:To explore the dynamic changes of thrombosbondin-1(TSP-1)and transforming growth factor beta(TGF-β)in patients who underwent hepatectomy and their clinical value in predicting post-hepatectomy liver failure(PHLF).Methods:Clinical data of 113 patients who received hepatectomy in the First Affiliated Hospital of Xinjiang Medical University from Janu-ary 2016 to March 2019 were retrospectively analyzed.The cohort comprised 59 males and 54 fe-males,with an average age of(41.00±13.98)years.According to the standard of the International Study Group of Liver Surgery(ISGLS),TSP-1 was divided into the PHLF group(n=40)and the non-PHLF group(n=73).The dynamic changes of plasma TSP-1 and TGF-β plasma levels during peri-operative period were observed.The definition and diagnostic criteria suggested by ISGLS was used to evaluate PHLF.The value of plasma TSP-1 and TGF-β level in predicting PHLF were ana-lyzed by calculating areas under the receiver operating characteristic curves(AUCs).Patients were divided into TSP-1 high group and TSP-1 low groups based upon the ROC cutoff values and their correlation with PHLF was analyzed.T test and Mann-Whitney rank sum test were performed to compare the TSP-1 and TGF-β levels between the two groups.The rate comparison was carried out by Chi-square test or Fisher's exact test.Results:In this study,40 patients experienced vary-ing degrees of PHLF.The plasma levels of TSP-1 on postoperative day I(POD1)and day 7(POD 7)in the PHLF group were significantly higher than those in the non-PHLF group(P＜0.05,P＜0.01,re-spectively).The area under the ROC curve of plasma TSP-1 level on postoperative 1 d in the diag-nosis of PHLF was 0.725,with sensitivity of 0.864 and specificity of 0.647.The area under the ROC curve of plasma TSP-1 level on postoperative 7 d in the diagnosis of PHLF was 0.81,with sensitiv-ity of 0.818 and specificity of 0.765.Conclusion:The incidence of PHLF is related to the extent of liver resection,Child-Pugh grade and TSP-1 levels on postoperative day 1.The concentration level of TSP-1 on POD land 7 might be utilized as an effective marker for predicting PHLF.
