[A proposition for a histopathologic examination protocol of liver biopsy in diagnosis of chronic hepatitis]

The authors present a proposition of a protocol of liver specimen examination including new criteria for describing a degree of inflammatory activity and advancement fibrosis. A suggested pattern of examination protocol is based on new criteria of chronic liver diseases diagnosing issued in 1994 by World Congress of Gastroenterology and International Association For the Study of the Liver (IASL). Introducing a unified protocol of liver specimen examination according to a suggested scheme will facilitate a clinical diagnosing of patients with a suspected chronic hepatitis. A histopathologist, having received full and very detailed data, will be able to issue a more precise interpretation of an observed histopathological image as well as in some cases to use some additional diagnostic methods. Applying a contemporary division of chronic hepatitis including either descriptive or scoring criteria of inflammatory activity and fibrosis range will decrease a risk of too subjective evaluation of a sample.
