Studies on atrophic liver cirrhosis on the basis of classification.

There are a large variety of cause of liver cirrhosis and numerous classifications , as related to the present disease, have been adopted in foreign countries , and among them a purely morphological, an etiological and a functional classification of liver cirrhosis are to be mentioned. In the Pan American Congress cf Gastroenterology held at Havana in 1956, the morphological classification concerned was finally established as follows : 1) portal cirrhosis, 2) postnecrotic cirrhosis, and 3) biliary cirrhosis . On the other hand, since Nagayo (1914) designated the most frequent pattern of liver cirrhosis of unknown etiology as atrophic liver cirrhosis and divided it into 2 types, type A and type B. This system of classification was modified later by Mitamura and Ishikawa (1940), and by Miyake (1960) and has been commonly used in this country, while it is still uncommon in others countries . In recent years the formentioned Havana classification is also being employed in our country. The author has attempted to make a comparative study on the Nagayo and Miyake's classification and the Havana classification using autopsy, as well as biopsy materials, in addition reference is to his own classification.
