Abstract: To clarify the relationship between resected (RSV) or remnant hepatic volume (RMV) in major hepatectomy, and standard liver volume (SLV) and its clinical significance, the RSV/SLV, RMV/SLV and the volume of regeneration (RGV)/RMV were examined in 41 patients including 19 with chronic hepatitis and 5 with obstructive jaundice who underwent lobectomy or extended lobectomy. The hepatic function was maintained in all patients. SLV was calculated by the body-surface area using Urata's formula. RGV was calculated by subtracting the RMV from the remnant liver volume at day 28 after hemi-hepatectomy. Measurement of the hepatic volume was performed by computed tomography. The means of RSV, RMV, RGV and SLV were 591 ツア 173, 459 ツア 119, 667 ツア 129 and 1128 ツア 129cm3, respectively. The means of RSV/SLV, RMV/SLV and RGV/RMV were 0.52 ツア 0.14, 0.41 ツア 0.12 and 1.54 ツア 0.47, respectively. RGV was inversely correlated with RMV/SLV (p<0.001) but not with the other parameters. RSV/SLV and RMV/SLV were not associated with long-term ascites and hepatic failure. The tendency of these results was similar in each patient with a normal liver, obstructive jaundice and chronic viral hepatitis. If the hepatic functional reserve is maintained, a liver with lower hepatic volume has potentially sufficient regeneration even in patients with an injured liver.
