Application Value Of Three-dimensional Visualization Combined With Indocyanine Green Fluorescence Technique In Laparoscopic Hepatectomy For Primary Liver Cancer

Objective:To compare the difference between 3-D visualization combined with indocyanine green fluorescence imaging technology in laparoscopic hepatectomy of primary liver cancer and conventional laparoscopic hepatectomy of primary liver cancer,and to explore the effect of three-dimensional visualization combined with indocyanine green fluorescence imaging technology in primary liver cancer.The application value of laparoscopic hepatectomy of liver cancer.Methods:A retrospective case-control study was used to collect the clinical data of 105 patients with primary liver cancer who were admitted to Shandong Qianfoshan Hospital affiliated to Shandong University from January 2019 to January 2021.Among them,3-D visualization combined with indocyanine green fluorescence imaging was performed.51 casesof primary liver cancer underwent laparoscopic hepatectomy(observation group),and 54 cases of primary liver cancer underwent laparoscopic hepatectomy(control group).The preoperative data,intraoperative data,postoperative data and follow-up data of the observation group and the control group were collected,and the differences between the two groups of preoperative data,intraoperative data,postoperative data and follow-up data were compared.Results:The preoperative indicators of the two groups were statistically compared and there was no obvious difference(P>0.05).The operation time[225(135.0)min vs 282.5(118.0)min,Z=-2.687,P=0.007]and intraoperative hepatic portal occlusion time(35.9±8.5 min vs 40.77±6.8 min t=3.183,P=0.002)in the observation group were shorter than those in the control group.The amount of intraoperative blood loss[300.0(200.0)ml 363.0(141.0)ml,Z=-2.62,P=0.009]in the observation group was lower than that in the control group.The postoperative complications[5(4.8%)vs 14(13.3%),χ2=4.600,P=0.032]were lower than those in the control group.Postoperative drainage tube removal time[7.0(5.0)d vs 8.5(4.0)d,Z=-2.313,P=0.021]were shorter than those in the control group and glutamic pyruvic transaminase(ALT)in the observation group were lower than those in the control group on the 1st.3rd and 5th day after operation[332.1(131.7)U/L vs 386.2(100.0)U/L,Z=-2.379,P=0.017;227.1±76.1 U/L vs 274.8±74.0 U/L,t=-3.257,P=0.002;114.4±51.7 U/L vs 151.1±61.0 U/L,t=-3.254,P=0.001].Conclusion:1.Compared with traditional laparoscopic hepatectomy of primary liver cancer,3-D visualization combined with indocyanine green fluorescence imaging technology in laparoscopic hepatectomy of primary liver cancer can effectively shorten the operation time,shorten the time of intraoperative hepatic portal block and reduce Intraoperative blood loss.2.Compared with traditional laparoscopic hepatectomy of primary liver cancer,3-D visualization combined with indocyanine green fluorescence imaging technology in laparoscopic hepatectomy of primary liver cancer can significantly shorten the postoperative catheterization time and reduce the occurrence of postoperative complications.,reduce the degree of postoperative liver damage.3.The application value of 3-D visualization combined with indocyanine green fluorescence imaging technology in laparoscopic hepatectomy of primary liver cancer is not inferior to traditional laparoscopic hepatectomy of primary liver cancer.
