Abstract
This article reviews the current evidence and knowledge of progressive liver fibrosis after pediatric liver transplantation. This often-silent histologic finding is common in long-term survivors and may lead to allograft dysfunction in advanced stages. Surveillance through protocolized liver allograft biopsy remains the gold standard for diagnosis, and recent evidence suggests that chronic inflammation precedes fibrosis.
Core tip: Progressive liver allograft fibrosis is a common finding after liver transplantation in children and may lead to allograft failure in the long-term. Recent data from centers performing sequential protocol biopsies after pediatric liver transplantation demonstrate that chronic inflammation precedes fibrosis. In this review, we provide an update on pathogenesis, diagnosis and management of progressive liver fibrosis in pediatric liver transplant recipients.
