Abstract：Objective To investigate the application of indocyanine green retention rate at 15 min (ICGR15) combined with three-dimensional evaluation system in the precise liver resection.Methods Forty-three patients with hepatocarcinoma and cirrhosis undergoing surgery were selected.We imported their preoperative intensive CT results into three dimensional evaluation system, and combined with preoperative ICGR15 and routine examination to develop and assess the surgical plan.According to the compensatory liver function after hepatectomy, we divided them into the liver function recovery group and hypohepatia group. The corresponding indicators of the two groups were analyzed.Results There were no statistically significant differences in age, operation time, preoperative transaminase, bilirubin and liver resection rate between the two groups (P>0.05).Significant differences were found in the preoperative acetylcholinesterase, preoperative and intraoperative ICGR15, bleeding volume and standardized remnant liver volume ratio between the two groups (P<0.05).The ROC area under the curve analysis showed that the cutoff value of intraoperative ICGR15/preoperative ICGR15(R) in predicting postoperative hepatic insufficiency was 1.781, the sensitivity was 85.7%, and the specificity was 86.2%.No statistically significant difference was found in predicting liver re-section volume and actual liver resection volume by using three-dimensional evaluation system (t=0.918, P=0.362), and the two numerical values had good correlation (r=0.989, P<0.05).Conclusion ICGR15 combined with three-dimensional evalua-tion system can better predict the recovery of liver function after liver resection, for patients, their R ( intraoperative/preopera-tive) is greater than 1.781, the risk of postoperative hepatic insufficiency is high;three dimensional evaluation system can help to measure liver volume, and help to make the preoperative surgical plan.
