The usefulness of immunohistochemical staining of bile tracts in biliary atresia.

Aim Of The Study: To assess ductular proliferation (DP) and ductal plate malformation (DPM) in biliary atresia (BA) by means of immunohistochemical staining using cytokeratins CK7 and CK19 and neural cell adhesion molecule (NCAM) antibody CD56.

Material And Methods: In 10 cases of BA, liver surgical biopsies obtained at the time of hepatoportoenterostomy were stained with H&E, PAS, Gomori and Azan methods. Immunohistochemical technique was used to outline bile ducts, ductular reaction, reactive bile duct/ductules and DPM by CK7, CK19 and NCAM antibody CD56.

Liver transplantation in children with biliary atresia and polysplenia syndrome.

Background: Children with biliary atresia and polysplenia syndrome (BA-PS) have always been considered as high risk liver transplant recipients due to technical problems during transplant surgery. We report single-center experience with liver transplantation in children with this syndrome.

Material/methods: Between 2000 and 2010, 401 liver transplantations were performed in 358 children, including 6 patients with BA-PS, who underwent living (5 patients) or deceased (1 patient) donor liver transplantation.

Liver transplantation with ABO incompatible graft under immunoadsorption protocol--case report.

Background: ABO incompatible liver transplantation is still controversial, but accepted in selected cases. Recently several authors reported use of the new technology aimed at elimination anti-donor ABO specific hemagglutinins to assist immunosuppression in preventing acute rejection after transplantation.

Case Report: We report two cases of liver transplantation in children with ABO incompatible graft under immunoadsorption protocol.

Hemodynamic failure as an indication to urgent liver transplantation in infants with giant hepatic hemangiomas or vascular malformations--report of four cases.

The aim of this study was to present acute hemodynamic failure as a rare indication for liver transplantation in neonates and infants with liver hemangiomatosis. We report four patients aged one to six months with giant liver hemangiomas, with huge arterio-venous shunting within these malformations. In three, many skin hemangiomas were found.
