- Abstract
- Background The objective of the study was to establish a right-lobe graft weight (GW) estimation formula for living donor liver transplantation (LDLT) from right-lobe graft volume without veins (GVw/o_veins), including portal vein and hepatic vein measured by computed tomographic (CT) volumetry, and to compare its estimation accuracy with those of existing formulas. Right-lobe GW estimation formulas established with the use of graft volume with veins (GVw_veins) sacrifice accuracy because GW measured intra-operatively excludes the weight of blood in the veins. Right-lobe GW estimation formulas have been established with the use of right-lobe GVw/o_veins, but a more accurate formula must be developed. Methods The present study developed right-lobe GW estimation formulas based on?GVw/o_veins as well as GVw_veins, using 40 cases of Korean donors: GW?= 29.1?+ 0.943?�� GVw/o_veins (adjusted R2?= 0.94) and GW?= 74.7?+ 0.773?�� GVw_veins (adjusted R2?= 0.87). The proposed GW estimation formulas were compared with existing GVw_veins- and GVw/o_veins-based models, using 43 cases additionally obtained from two medical centers for cross-validation. Results The GVw/o_veins-based formula developed in the present study was most preferred (absolute error?= 21.5 �� 16.5 g and percentage of absolute error?= 3.0 �� 2.3%). Conclusions The GVw/o_veins-based formula is preferred to the GVw_veins-based formula in GW estimation. Accurate CT volumetry and alignment between planned and actual surgical cutting lines are crucial in the establishment of a better GW estimation formula. ? 2016 Elsevier Inc.
