Abstract:
Objective To study three-dimensional reconstruction system (IQQA-Liver) in evaluation of resection volume and margin of hepatocellular carcinoma.Method Data of 51 hepatocellular carcinoma patients undergoing hepatectomy from March 2014 to October 2015 were analyzed retrospectively.All patients received preoperative ultrasound and CT/MIR evaluation.Three-dimensional reconstruction system (IQQA-Liver) was used to reconstruct tumor shape and location,the relationship between tumor and adjacent vessels or bile ducts.Then liver volume,liver resection volume,residual liver volume and surgical margin were calculated and compared with the actual resection liver values and actual margin.Results Images of three-dimensional reconstruction system (IQQA-Liver) were accurate,clear and directly perceived.In terms of the resection liver volume and resection margin,there was no significant difference between the predicted results and actual results [resection liver volume:(412.93 ± 471.26)cm3 vs.(487.02±529.01)cm3,t=0.75,P=0.46,resection margin:(13.72 ± 4.58) mm vs.(13.92 ±4.21)mm,t =0.23,P =0.82].The predicted resection liver volume was significantly correlated with the actual resection volume (r =0.91,P ＜ 0.01),the predicted resection margin was also correlated with the actual resection margin (r =0.89,P ＜ 0.01).Conclusion Three-dimensional reconstruction system (IQQALivcr) could accurately assess the resection volumc and margin of hepatocellular carcinoma.
