The liver in biliary obstruction due to chronic pancreatitis.
Biliary obstruction is an important complication of chronic calcifying pancreatitis. In this study, liver biopsies were examined to determine the nature and severity of hepatic complications in 23 such cases. The most striking changes were portal tract expansion due to oedema and fibrosis, with proliferation of bile ducts. Although common, these changes were not severe, and no patient had developed secondary biliary cirrhosis. Other features of note were intrahepatic cholestasis, iron overload (56.5%), copper-associated protein stained with the orcein technique (34.7%) and mild fatty change or perivenular sclerosis in 13%. It is concluded that no serious, irreversible pathological changes occurred in the liver despite clinically marked biliary obstruction.
