Pathology with reference to the bile retention syndrome.

The pathological significance ofgiant cells, inspissitated bile plugs and hepatic fibrosis in the liver of infants is critically reviewed. Evidence is presented suggesting that a wide variety of pathological change in the paediatric liver results from the interaction of the effects of growth, metabolic maturity, genetic metabolic variability and infection. Understanding of the bile retention syndromes might increase if the diagnosis of 'Neonatal Hepatitis' and 'biliary atresia' as finite conditions, were to cease and their pathogenesis considered in such a multifactorial way.
