Division of Hepatobiliary Surgery and Liver Transplantation, Department of Surgery, Asan Medical Center, University of Ulsan College of Medicine, Seoul, Korea Backgrounds/Aims: Formula-derived standard liver volume (SLV) has been clinically used for living donor liver transplantation and hepatic resection. The majority of currently available SLV formulae are based on body surface are (BSA). However, they often show a wide range of error. Skeletal muscle index measured at the third lumbar vertebra level (L3SMI) appears to reflect lean body mass. The objective of this study was to compare the accuracy of L3SMI-based formula and BSA-based formula for calculating SLV. Methods: The study cohort was 500 hundred living liver donors who underwent surgery between January 2010 and December 2013. Computed tomography images were used for liver volumetry and skeletal muscle area measurement. Results: The study cohort included 250 male and 250 female donors. Their age, BSA, L3SMI, and body mass index were 26.8±8.7 years, 1.68±0.16 m², 45.6±9.0 cm²/m², and 21.7±2.5 kg/m², respectively. The BSA-based SLV formula was “SLV (ml)=−362.3+901.5×BSA (m²) (r=0.71, r²=0.50, p＜0.001)”. The L3SMI-based SLV formula was “SLV (ml)=471.9+14.9×L3SMI (cm²/m²) (r=0.65, r²=0.42, p＜0.001)”. Correlation coefficients were similar in subgroup analyses with 250 male donors and 250 female donors. There was a crude correlation between L3SMI and body mass index (r=0.51, r²=0.27, p＜0.001). Conclusions: The results of this study suggest that SLV calculation with L3SMI-based formula does not appear to be superior to the currently available BSA-based formulae.
