Abstract
Objective：Discussing the assessment value of liver reserve function for reservation liver volume rate before hapetectomy for hepatoma.
Methods：59 cases of operative liver cancer patients were studied. All patients were checked by two-phase CT scanning. The reservation liver volumes were measured with CT before operation and the reservation liver volumes rate {the ratio of reservation liver volume to estimated liver volume，the estimated liver volume=121.745+16.490×body weight(kg)} were calculated. The reservation liver volumes were compared with the postoperative survival rate to carry out the difference analysis of intergroup.
Results：The difference of survival rate between the retain liver volume rate ≤ 50％ group and > 50％ group was of valuable significance in statistics (V 2＝4.9881，p < 0.05 ); Otherwise, the difference of survival rate between the resected liver volume rate ≤ 50％ group and > 50％ group was not of valuable significance in statistics (V 2 ＝ 0.0154，p > 0.05 ) .
Conclusion：Reservation liver volume rate can be one of important index of liver reserve function for the clinical skill of liver cancer.
