Resected 27 cases of the minute liver cancer with less than 5cm in diameter were analysed. The liver cirrhosis was combined in 24 cases, Periodic image diagnosis is recommended in cirrhotic patients even with low level of AFP.<BR>The pseudocapsule fbrmation was observed in 93% of cases, intracapsular invasion in 15% and extracapsular in 30%. The vascular invasion was detected in 74%, however, the correlation between the size of the tumor and presence or absence of vascular invasion was not observed. Because high incidence of vascular invasion and frequent liver cirrhosis is the most important problem in surgery, the new method of resection, selective removal of the limited tumor bearing area which is defined by the vascular structure, designated "systematic sub-segmentectomy" was originated and employed using operative ultrasonography. The result of operation was improved by this procedure and by prophylactic use of large dose of Aprotinin.
