title: [Estimation formula of standard liver volume for Chinese adults].
abstract: 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.
  
  
  RESULTS
  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.
