Abstract
ObjectiveTo explore the role of computer-assisted quantitative analysis in assessing the safety of hepatic resection before surgery and determining the surgical approach.
MethodsThe data of 30 patients undergoing hepatocellular carcinoma resection in our hospital were analyzed. By preoperative CT enhanced scan, combined with the United States EDDA company IQQA (R)-Liver system for three-dimensional reconstruction of liver CT images, total liver volume (TLV), tumor volume (TV), functional liver volume (FLV), excised functional liver volume (EFLV), excised liver volume (ELV), future liver remnant (FLR), actual excised liver volume (AELV), and standard liver volume (SLV) were calculated. Data about operation time, intraoperative blood loss, postoperative complications and mortality were collected. At-test was performed on ELV and AELV, and the correlation between TV and EFLV or FLR was analyzed.
ResultsThe difference between ELV (686±488) and AELV (687±485) was not statistically significant (t=-0.370, P=0.773). The surgical plan for preoperative simulated liver cancer resection was consistent with the actual surgical plan. Spearman correlation test was performed on TV and EFLV and FLR. TV was positively correlated with EFLV (r=0.392, P=0.010) and negatively with FRL (r=-0.476, P=0.003). There were no patients with liver failure and deaths after surgery.
ConclusionThe use of computer-assisted 3D-assisted quantitative analysis for preoperative simulated surgery could fully evaluate the preoperative safety of hepatic resection. FLR could be used to determine different surgical methods. FLR would be used to determine different surgical methods. FLR/SLV is an ideal index to evaluate the scope of surgical resection.
