We retrospectively reviewed 115 cases of living donors for right lobes of liver transplants, not including the middle hepatic veins, in our hospital. The weights and volumes of the right lobe liver grafts were measured and recorded in the surgery. The actual total volume of liver was calculated from the right lobe graft volume divided by the proportion of the right lobe as indicated in the computed tomography. Simple linear regression analysis and stepwise multiple linear regression analysis were undertaken to develop a formula for calculating the total liver volume, which was compared with other existing formulae.
The liver donors had a mean age of (35.97 +/- 9.6) years old, and a female to male ratio of 60:55. The computed tomography detected a mean volume of (727.47 +/- 136.17) mL of right lobe, which occupied 55.59% +/- 6.70% of the entire livers. The right lobe grafts had an actual volume of (581.73 +/- 96.137) mL and the donors had an actual total liver volume of (1053.08 +/- 167.56) mL. A formula was developed for calculating the standard liver volume: SLV(mL) = 11.508 x Body Weight + 334.024. The HongKong formula underestimated, whereas all of the other formulae overestimated the actual liver volume of the donors. Conclusion The standard liver volume of Chinese adults can be calculated as: SLV = 11.508 x Body Weight + 334.024.
我们回顾性分析了我院115例活体右半肝移植供体（不包括肝中静脉）。术中测量并记录右半肝移植物的重量和体积。根据计算机断层扫描所示右半肝的比例，由右半肝移植物体积计算肝脏实际总体积。采用简单线性回归分析和逐步多元线性回归分析来推导计算肝脏总体积的公式，并与其他现有公式进行比较。
肝脏供体的平均年龄为（35.97±9.6）岁，男女比例为60:55。计算机断层扫描显示右半肝平均体积为（727.47±136.17）mL，占全肝的55.59%±6.70%。右半肝移植物实际体积为（581.73±96.137）mL，供体肝脏实际总体积为（1053.08±167.56）mL。推导得出计算标准肝脏体积的公式：SLV（mL）=11.508×体重+334.024。香港公式低估了供体的实际肝脏体积，而其他所有公式均高估了供体的实际肝脏体积。结论中国成年人的标准肝脏体积可按以下公式计算：SLV = 11.508×体重+334.024。
