We investigated the overall situation of LT for BA in mainland China and analyzed their survival outcomes based on data from CLTR. Between January 1996 and December 2013, 509 liver transplants for BA were performed in mainland China and were included in this study. Patients' median age was 9.6 months (range: 4.8-175.2 months). KP was previously performed in 194 cases (38.1%). Grafts from living donors were used in 380 cases (74.7%). Era I (1996.1-2010.12) and era II (2011.1-2013.12) comprised 151 cases (29.7%) and 358 cases (70.3%), respectively. Twenty-five centers had performed at least one liver transplant for children with BA. Centers from Shanghai (197 cases), Tianjin (143 cases) and Beijing (81 cases) involved 82.7% of the 509 cases. One- and five-yr graft survival rates were 84.7% and 72.6%, respectively. Split grafts, center volume <20, GRWR ≥4.0%, and steroid-free immunosuppression regimen were independent risk factors for graft survival. In conclusion, the dramatic expansion of pediatric liver transplant programs in mainland China has enabled improved survival for those children affected by this devastating disease. However, screening of BA in neonates should be emphasized throughout the country to enhance early referrals for KP. [ABSTRACT FROM AUTHOR]

We aimed to assess the impact of size mismatching between grafts and recipients on outcomes of infants or small children after LDLT. Between October 2006 and December 2014, 129 LDLT recipients weighing no more than 8 kg were retrospectively analyzed. The entire cohort was categorized into three groups by GRWR: GRWR<3.0% (group A, n = 38), 3.0%≤GRWR<4.0% (group B, n = 61), and GRWR≥4.0% (group C, n = 30). Baseline characteristics were similar among groups A, B, and C. Compared with groups A and B, post-transplant alanine aminotransferase and aspartate aminotransferase within seven days were significantly higher in group C; however, differences between total bilirubin and albumin after transplantation were not prominent. Moreover, incidences of surgical complications, perioperative deaths, infections, and acute rejections were all comparable among the three groups. Five-yr patient survival rates for groups A, B, and C were 89.5%, 88.9%, and 81.6%, respectively (p = 0.872), and the graft survival rates were 89.5%, 86.6%, and 81.6%, respectively (p = 0.846). In conclusion, GRWR between 1.9% and 5.8% would not cause noticeable adverse events for infantile LDLT recipients ≤8 kg. However, there is still a role for considering reduction in the graft mass as an applicable strategy in selected cases. [ABSTRACT FROM AUTHOR]
