摘　　要：目的评价3D重建及打印技术在肝脏外科术前精准评估的作用和意义。方法回顾性分析2016年1月至2019年1月间接受肝切除术患者80例。根据术前评估的方式不同,将患者分为术前3D重建及打印技术组(3D组,n=40)和未进行术前3D重建及打印技术(非3D组,n=40)两组。采用SPSS20.0统计软件分析,两组围术期各项指标以(x^-±s)表示,独立t检验;并发症及术后死亡率比较采用χ^2分析;预测的切除肝体积与实际切除体积进行相关性分析;P<0.05差异有统计学意义。结果3D组的中位手术时间比非3D组短36 min(P=0.048)。两组其他结果无显著性差异。亚组分析显示,重复肝切除和节段切除的手术时间3D组明显短于非3D组(P=0.03)。预测的肝脏体积与实际切除肝脏重量呈显著正相关(r=0.80,P<0.001)。结论术前3D重建及打印技术可以缩短手术时间,特别是重复肝切除和节段切除术。Objective To evaluate the role and significance of 3D reconstruction and printing technology in accurate preoperative evaluation of liver surgery.Methods Clinical data of 80 patients underwent hepatectomy,from January 2016 to January 2019,were analyzed retrospectively.According to the different preoperative evaluation,patients were divided into preoperative 3D reconstruction and printing technology group(3D group,n=40)and non-preoperative 3D reconstruction and printing technology group(non-3D group,n=40).Statistical analysis were performed by using SPSS20.0 software.Measurement data such as perioperative indicators were expressed as mean±standard deviation and were examined by independent t test.Count data such as complication rate and mortality were described by(n,%)and were examined by chi square test.The correlation between predicted resected liver volume and actual resected liver volume were also analyzed.A P value of<0.05 was considered as statistically significant.Results The median operation time of 36 min in the 3D group was shorter than that in non-3D group(P=0.048).There were no significant differences in other outcomes between two groups.Subgroup analysis showed that the operation time in 3D group was significantly shorter than that in non-3D group(P=0.03).There was a significant positive correlation between the predicted liver volume and the actual liver weight(r=0.80,P<0.001).Conclusion 3D reconstruction and printing technology could shorten the operation time,especially repeated hepatectomy and segmental resection.
