目的 探讨三维可视化技术在肝细胞癌(hepatocellular carcinoma,HCC)术前评估中的应用价值.方法 回顾性分析2015年1月至2016年12月在徐州医科大学附属淮安医院肝胆外科24例HCC患者临床资料.患者术前经320排增强CT获取薄层扫描数据,以医学数字成像和通信(digital imaging and communications in medicine,DICOM)格式存储,应用三维可视化技术进行三维重建和手术方案模拟,并进行相关性分析.结果 全部患者均进行肝脏三维重建,并规划手术方案,24例手术患者术前预切除肝脏体积(565±296) ml,实际切除肝脏体积(523±252) ml,两者比较差异无统计学意义(t=1.734,P >0.05),呈正相关(r=0.920,P<0.05).术前测量肿瘤距切缘的最近距离为(1.2±0.6)cm,术后测量实际距离为(1.0±0.5)cm,两者比较差异无统计学意义(t=1.853,P>0.05),呈正相关(r=0.956,P<0.05).结论 三维可视化技术能够对HCC患者术前进行精准评估,具有一定的临床指导意义.
Objective To explore the value of medical three-dimensional visualization technology in preoperative precise assessment for hepatocellular carcinoma (HCC).Methods The clinical data of 24 HCC patients were analyzed retrospectively from Jan 2015 to Dec 2016 in our department.Thin-layer 320-slice CT scaning was performed and data stored in the form of DICOM.Three dimensional reconstruction and simulated hepatectomy were conducted,and correlation test analysis was performed.Results The volume of simulated resected liver was (565 ± 296)ml,while the actual liver resection volume was(523 ± 252)ml.There was no significant difference between the predicted and the actual values (t =1.734,P > 0.05).The actual liver resection volume was positively correlated with the predicted liver resection volume (r =0.920,P < 0.05).The stimulated resection margin was (1.2 ± 0.6)cm,while the actual resected tumor margin was (1.0 ± 0.5) cm.There was no significant difference between the predicted and the actual values (t =1.853,P >0.05).The actual margin was positively correlated with the predicted one (r =0.956,P < 0.05).Conclusion The three-dimensional visualization technology has a certain degree of clinical value in the preoperative evaluation of HCC.
