Application Value Of 3D Visualization Technique In Radical Resection Of Primary Liver Cancer

Objective To investigate the application value of 3D visualization technique in preoperative evaluation and intraoperative navigation during radical resection of primary liver cancer.Methods A retrospective analysis was performed on the medical records of 63 patients who underwent laparoscopic hepatectomy and were pathologically diagnosed as hepatocellular carcinoma in the People’s Hospital of Ningxia Hui Autonomous Region from March 2019 to March 2022.The patients were divided into 3D group(experimental group)and control group according to whether 3D visualization technology was used to guide the completion of surgery.There were 28 patients in the 3D group(experimental group)and 35 patients in the control group.To explore the advantages of 3D visualization technology in preoperative evaluation and intraoperative guidance during radical resection of primary liver cancer by comparison between groups.Results 1.There was no significant difference in preoperative baseline data between the two groups(P > 0.05),and the baseline data of the two groups were comparable and balanced.2.3 Preoperative simulated liver resection volume was highly correlated with actual liver resection volume in group D(r=0.987,P < 0.001).3.The operation time,intraoperative blood loss and hilar occlusion time of the 3D group and the control group were(4.96±1.64)h and(6.34±1.75)h,respectively.560(425,787.5)ml,800(600,1500)ml;(66.6±16.4)min,(77.4 ± 16.2)min,the differences were statistically significant(P < 0.05),suggesting that compared with the control group,the operation time in the 3D group was shorter,the intraoperative blood loss was less,and the hilar occlusion time was shorter.The indentation time of drainage tube and postoperative hospitalization days of 4.3D group and control group were(7.9±3.2)days and(9.1±1.3)days,respectively.(14.6±2.3)days,(12.7±2.1)days,the difference was statistically significant(P < 0.05).Compared with the control group,the length of drainage indwelling and postoperative hospitalization were shorter in the3 D group.5.In the 3D group,there were 1 case of liver failure,1 case of bile leakage,1 case of pulmonary infection and 2 cases of pleural effusion.In the control group,there were 2cases of liver failure,2 cases of bile leakage,1 case of abdominal hemorrhage,3 cases of pulmonary infection,4 cases of pleural effusion,and 1 case of abdominal infection.There was no significant difference between the two groups(P > 0.05).Conclusion 1.3D visualization technology can accurately identify vascular system variation in the liver.2.Before surgery,3D visualization technology can help clinicians make accurate evaluation in terms of determining resectable and designing excision scope,and guide the completion of surgery during the operation.It can significantly reduce the operation time,reduce the amount of blood loss,so as to make the postoperative recovery faster and reduce the postoperative hospitalization days of patients.
