Abstract: The most common indication for pediatric LTx is biliary atresia with failed HPE, yet the effect of previous HPE on the outcome after LTx has not been well characterized. We retrospectively reviewed a single-center experience with 134 consecutive pediatric liver transplants for the treatment of biliary atresia from 1 May 1995 to 28 April 2008. Of 134 patients, 22 underwent LTx without prior HPE (NPE), while 112 patients underwent HPE first. HPE patients were grouped into EF, defined as need for LTx within the first year of life, and LF, defined as need for LTx beyond the first year of life. NPE and EF groups differed significantly from the LF group in age, weight, PELD, and ICU status (p < 0.05) with NPE having the highest PELD and ICU status. Patients who underwent salvage LTx after EF following HPE had a significantly higher incidence of post-operative bacteremia and septicemia (p < 0.05), and subsequently lower survival rates. One-year patient survival and graft survival were as follows: NPE 100%, EF 81%, and LF 96% (p < 0.05); and NPE 96%, EF 79%, and LF 96% (p < 0.05). Further investigation into the optimal treatment of biliary atresia should focus on identifying patients at high risk of EF who may benefit from proceeding directly to LTx given the increased risk of post-LTx bacteremia, sepsis, and death after failed HPE.

    ABSTRACT: It is encouraging that we are improving the technical aspects of treatment modalities for biliary atresia. However, it is clear that more needs to be done to best develop new treatment plans while applying the modalities we have (porto-enterostomy or liver transplantation or both) in a way that will afford the best survival and quality-of-life. This review article will discuss a number of points that are vital to improving care and illustrates the need to further scrutinize treatment decisions.

    ABSTRACT: Congenital biliary atresia is a rare condition characterized by idiopathic dysgenesis of the bile ducts. If untreated, congenital biliary atresia leads to liver cirrhosis, liver failure and premature death. The present study aimed to evaluate the outcomes of orthotopic liver transplantation in children with biliary atresia. We retrospectively analyzed 45 patients with biliary atresia who had undergone orthotopic liver transplantation from September 2006 to August 2012. The median age of the patients was 11.0 months (5-102). Of the 45 patients, 41 were younger than 3 years old. Their median weight was 9.0 kg (4.5-29.0), 34 of the 45 patients were less than 10 kg. Thirty-one patients had undergone Kasai portoenterostomy prior to orthotopic liver transplantation. We performed 30 living donor liver transplants and 15 split liver transplants. Six patients died during a follow-up. The median follow-up time of surviving patients was 11.4 months (1.4-73.7). The overall 1-, 2- and 3-year survival rates were 88.9%, 84.4% and 84.4%, respectively. With advances in surgical techniques and management, children with biliary atresia after liver transplantation can achieve satisfactory survival in China, although there remains a high risk of complications in the early postoperative period.

    ABSTRACT: Liver grafts can at times have two hepatic arterial stumps. This can result in a dilemma whether to reconstruct single or both the arteries. Hepatic artery (HA) thrombosis is the most dreaded complication in pediatric living donor liver transplantation (LDLT) as it can result in biliary complications and subsequent graft loss. We herein report the feasibility of reconstructing single hepatic artery in pediatric living donor liver transplantation having two arterial stumps in the liver graft. From 2008 to 2010, 87 pediatric patients undergoing LDLT were divided into three groups. Group 1 (n = 20): two HA stumps with two HA reconstruction, Group 2 (n = 22): two HA stumps with one HA reconstruction and Group 3 (n = 45): one HA stump with one HA reconstruction. The decision regarding the reconstruction of single or multiple HAs was made depending on the pre-operative radiological and intraoperative assessments. The incidence of HA thrombosis (p = 0.126) and biliary complications (p = 0.617), was similar in the three groups. Single HA reconstruction does not increase the risk of biliary strictures in pediatric LDLT recipients having dual hepatic arterial stumps in the liver graft.
