RESUMO
OBJECTIVES: This study analyses the prognosis of biliary atresia (BA) in France since 1986, when both Kasai operation (KOp) and liver transplantation (LT) became widely available. METHODS: The charts of all patients diagnosed with BA born between 1986 and 2015 and living in France were reviewed. RESULTS: A total of 1428 patients were included; 1340 (94%) underwent KOp. Total clearance of jaundice (total bilirubin ≤20âµmol/L) was documented in 516 patients (39%). Age at KOp (median 59 days, range 6-199) was stable over time. Survival with native liver after KOp was 41%, 35%, 26%, and 22% at 5, 10, 20, and 30 years, stable in the 4 cohorts. 25-year survival with native liver was 38%, 27%, 22%, and 19% in patients operated in the first, second, third month of life or later, respectively (Pâ=â0.0001). Center caseloads had a significant impact on results in the 1986 to 1996 cohort only. 16%, 7%, 7%, and 8% of patients died without LT in the 4 cohorts (Pâ=â0.0001). A total of 753 patients (55%) underwent LT. Patient survival after LT was 79% at 28 years. Five-year patient survival after LT was 76%, 91%, 88%, and 92% in cohorts 1 to 4, respectively (Pâ<â0.0001). Actual BA patient survival (from diagnosis) was 81%. Five-year BA patient survival was 72%, 88%, 87%, and 87% in cohorts 1986 to 1996, 1997 to 2002, 2003 to 2009, and 2010 to 2015, respectively (Pâ<â0.0001). CONCLUSIONS: In France, 87% of patients with BA survive nowadays and 22% reach the age of 30 years without transplantation. Improvement of BA prognosis is mainly due to reduced mortality before LT and better outcomes after LT.

This study analyzes the preoperative risk factors for intra-operative bleeding in our recent series of pediatric LTs. Between November 2009 and November 2014, 84 consecutive isolated pediatric LTs were performed in 81 children. Potential preoperative predictive factors for bleeding, amount of intra-operative transfusions, postoperative course, and outcome were recorded. Cutoff point for intra-operative HBL was defined as intra-operative RBC transfusions ≥1 TBV. Twenty-six patients (31%) had intra-operative HBL. One-year patient survival after LT was 66.7% (CI 95%=[50.2-88.5]) in HBL patients and 83.8% (CI 95%=[74.6-94.1]) in the others (P=.054). Among 13 potential preoperative risk factors, three of them were identified as independent predictors of high intra-operative bleeding: abdominal surgical procedure(s) prior to LT, factor V level ≤30% before transplantation, and ex situ parenchymal transsection of the liver graft. Based on these findings, we propose a simple score to predict the individual hemorrhagic risk related to each patient and graft association. This score may help to better anticipate intra-operative bleeding and improve patient's management.
