Abstract
Pancreatoblastoma is a malignant exocrine pancreatic tumor that is usually present in childhood. We herein present one case of pediatric living donor liver transplantation (LDLT) combined with spleen-preserving regional total pancreatectomy and portal vein homograft interposition in a 4-year-old boy with advanced pancreatoblastoma invading the portal and superior mesenteric veins. The size of the pancreatoblastoma was gradually reduced along systemic chemotherapy, thus we decided to perform surgery to remove it completely. A cold-stored fresh iliac vein homograft was prepared. Initially, a spleen-preserving distal pancreatectomy was performed. Thereafter, a completion regional total pancreatectomy was performed under superior mesenteric vein-vena cava bypass. A left liver graft from his mother was implanted according to the standardized procedures with portal vein interposition. This patient recovered uneventfully and is currently undergoing scheduled adjuvant chemotherapy. To our knowledge, this is the world-second case of pediatric LDLT for advanced pancreatoblastoma. Availability of fresh vein homografts is helpful to expand the indication of pediatric LDLT.
