title: [Clinical characteristics and imaging diagnosis of early cancer in the hepatobiliary and pancreatic region].
abstract: For the present, we don't have any reliable definition of the early cancer in hepato-biliary and pancreatic region. In this paper three examples of comparatively early cancer were taken up; (1) among hepatocellular carcinoma, so called, small liver cancer; (2) among gallbladder carcinoma and bile duct carcinoma, those whose extent of infiltration within pm and fm respectively; (3) among pancreatic carcinoma, those whose maximum diameter are 2 cm. And the system of imaging diagnosis was discussed as well as the discussion of their clinical characteristics, imaging diagnosis and the differential diagnosis.
