Abstract:
Objective To explore the value of three-dimensional reconstruction technology in the preoperative assessment of hepatocellular carcinoma (HCC) patients treated with extensive hepatectomy. Methods The clinical data of 45 HCC patients undergoing extensive hepatectomy (≥4 segments) in Jiangsu Taizhou Peoples Hospital between January 2016 and June 2018 were analyzed retrospectively. All the patients underwent thin-slice CT examination before operation, and three-dimensional reconstruction system (IQQA-Liver) was used for preoperative assessment. The relationship between tumor and hepatic blood vessels was fully displayed in preoperative assessment and then the operation procedure was simulated for calculating liver volume, removed liver volume, residual liver volume and surgical margin. The simulated liver volume and surgical margin were then compared with the actual surgical results. Results The liver tissues, hepatic vessels, tumor, and the adjacent relationship of tumor and hepatic vessels of 45 patients were clearly displayed after three-dimensional reconstruction. There was no significant difference between the removed liver volume in simulation and the actually removed liver volume[(845.2+285.5) mL vs (826.3± 268.1) mL t=0.425, P>0.05], between simulated surgical margin and actual margin[(11.2±3.4) mm vs (10.6±2.8) mm t=0.471, P>0.05)]. Both the two above-mentioned indexes in simulation were positively correlated with the actual operation (r=0.95, P<0.01 r=0.83, P<0.01). Conclusion Three-dimensional reconstruction technology can clearly show the relationship between hepatic tumor and hepatic vessels, accurately evaluate the hepatic volume and surgical margin of liver resection, with certain clinical value in extensive hepatectomy.
