Biliary Tract Complications

Biliary Tract Complications: Biliary tract complications are a common source of histopathological changes in the liver allograft and are identical to those seen in non-allograft livers. Complications recognizable on light microscopy include biliary stricturing and/or obstruction, ascending cholangitis, hemobilia, biliary-vascular fistulas and viral infections. It should be stressed however, that incomplete biliary tract obstruction can produce changes that mimic both acute rejection and viral hepatitis, particularly when the patient has survived for more than one year after transplantation. Therefore, close clinical correlation, including the results of recent cholangiographic studies and liver injury tests is needed.
