摘　　要：目的探讨3D打印技术在肝脏切除术中的临床应用价值。方法我院2015年3~5月期间对6例肝细胞癌、3例肝血管瘤和3例肝内外胆管结石患者术前常规CT检查后行肝脏3D重建,并存为STL文件,按肝脏实际大小50%~70%、采用聚乳酸材料打印出肝脏模型,然后进行后期处理后分析肝脏解剖、手术规划和模拟手术,选择最优手术路径和方案,在3D打印肝脏模型指导下行肝脏切除。结果肝脏切除方式与术前肝脏模型上手术规划一致,术中平均出血量340 m L,无手术并发症。结论 3D打印肝脏切除术使肝脏切除更加精准、安全。Objective To explore clinical value of 3D printing technology in hepatic resection.Methods From March to May 2015,multidetector-row computed tomography images of 12 patients,including hepatic carcinoma in 6,hepatic hemangioma in 3,intra- and extra-hepatic bile duct stones in 3,were used for 3D hepatic reconstruction,the final segmentation data were converted to stereolithography files for 3D printing,50%- 70%scale of the full-sized liver model was fabricated by polylactic acid to be used to analyze its anatomical structure,design surgical planning,select the optimal operative route and simulate hepatic resection.Hepatic resection was performed by referring to the 3D printing model.Results The hepatic resections were successful without complications by referring to the preoperative 3D printing models,the average blood loss was 340（100- 1 000） ml.Conclusion Hepatic resection is more accurate and safe by 3D printing technology.
