The Usefulness of Liver Volume Measurement Using CT Image as Reference Data in Living Donor Liver Transplantation

It aimed at suggesting the concrete mensuration of liver volume calculation and checking the utility by comparing the difference between the volume data which we have measured at 3D-lab. by reducing the error bound of the measured data and the data which is substantially measured at the surgery room. It considered if there is the value of reference data of the volume data which is measured as manual method. The average weight of the graft which had been resected at the substantial surgery room was 680.53±137.35g, and the manual measurement volume average volume was 797.87±165.86㎤. Two data and correlation evaluation appeared to be(γ=0.83535 P<0.001). The gap between the volume data of manual method and the volume data which was substantially measured was 117.93±13.97%, and it shows significant gap in figure. The reason is plausible to be regarded as the reduction of volume(or mass) reduction due to the bleed at the time of operation resection. Meanwhile, what shows the considerably significant gap as 95% CI for the mean(114.72% to 121.14%, P=0.016 in the ratio of the gap) is judged to be valuable as the reference data before the surgery.
