A study on the correlation between hepatic volume and liver functional reserve / 中国普通外科杂志

ABSTRACT

Objective To establish standard liver volume formula of healthy Chinese and to explore if there is a correlation between changes of hepatic volume and hepatic functional reserve.Methods Two hundred and eighty healthy volunteers and 85 cirrhotics undergone serial abdominal H-CT scanning. The relation between normal liver volume measured by CT and body surface area(BSA) was studied by linear regression and correlation method, the standard liver volume formula was deduced. For cirrhotic patients, the change rate of liver volume was calculated and was compared with their Child class and postoperative complications.Results The mean normal hepatic volume for Chinese adults was (1?250?141)?cm 3. There is a positive correlation between estimated liver volume in vivo and body surface area[r=0.96, LV(cm 3)=613?BSA(cm 3)+162.8]. The mean liver volume (SD) for Child class A cirrhotics was (1?092?276)?cm 3, (868?163)?cm 3 for class B, and (652?76)?cm 3 for class C. Differences were observed among the three classes (P
