Abstract:
Objective To investigate the clinical effect of improved right hemihepatectomy（MRH）in the treatment of hepatocellular carcinoma（HCC）under the guidance of indocyanine green（ICG）tracer and 3D visualization technology.
Methods Clinical data of 92 patients with HCC who received MRH from January 2018 to December 2020 were retrospectively analyzed，and the patients were divided into traditional group（n=50）and combined group（n=42）according to whether they were guided by ICG tracer combined with 3D visualization technology. Conventional imaging was used to evaluate MRH in the traditional group，and ICG tracer combined with 3D visualization was used to guide MRH in the combined group. The data were processed by SPSS 22.0 software，and measurement data such as perioperative indicators and liver function indicators were represented by（
±
s）.
Repeated measurement analysis of variance was performed for liver function indicators，and independent sample
t test was performed for other indicators. The statistical data of postoperative complications were
chi-
square test. Survival analysis was performed by
Kaplan-
Meier method and
Log-
Rank test.
P<0.05 was considered statistically significant.
Results Operation time，hilar occlusion time and intraoperative blood loss in combination group were significantly lower than those in traditional group（P<0.05）. There was no interaction between time and method at albumin（ALB），total bilirubin（TBil）and alanine aminotransferase（ALT）levels（P>0.05），but the main effect of time and method was significant at ALB，TBil and ALT levels（P<0.05）. The total incidence of postoperative complications in the combination group was significantly lower than that in the traditional group（11.9% vs. 30.0%，P<0.05）. During the follow-up period，the cumulative overall survival rate and disease-free survival rate of the combination group were significantly higher than those of the traditional group（P<0.05）.
Conclusion The treatment of HCC with MRH under the guidance of ICG tracer and 3D visualization technology can not only effectively shorten the operation time and reduce intraoperative injury，but also benefit the postoperative liver function recovery of patients，reduce the occurrence of postoperative complications and improve the prognosis of patients.
