Background Nonalcoholic fatty liver disease (NAFLD) has now become a common cause of chronic liver disease in children; however, unlike adults liver transplantation is rarely required as treatment. It is important that in children presenting with NAFLD, secondary causes of fatty liver particularly inherited metabolic defects should be excluded.

Methods A pediatric working group comprised of 3 hepatologists and a liver transplant surgeon was tasked with a set of questions to address the current state of evidence and knowledge about NAFLD in children with particular focus on liver transplantation. A systematic review of the English literature regarding pediatric NAFLD (from birth to 18 years of age) published in the last 2 decades (2000-2018) was carried out. The evidence was evaluated by the subgroup members and further discussed with the wider workshop faculty leading to the recommendations for best practice.

Results Given the paucity of literature on the subject good quality of evidence was only available on risk factors for NAFLD and medical treatment where the group could make recommendation with high/moderate strength. The evidence on natural history and indications for liver transplantation was poor hence group could not make any recommendations.

Conclusions Based on the existing literature and subgroups, collective experience NAFLD unlike in adults is a very rare indication for liver transplantation in children. No definitive recommendations could be made about the natural history, indications, and outcome of liver transplantation for NAFLD in children.
