Abstract    Objective    To explore the application value of three dimensional visualization and 3D printing technology in the preoperative evaluation of retroperitoneal tumors. Methods    March 2011 to September 2015， the clinical data of 50 cases of retroperitoneal tumor patients in Xiamen University Affiliated successful hospital were retrospectively analyzed. Xiamen strong science and technology R & D human organ 3D modeling software will reconstruct 2D CT image visualization into a three-dimensional visualization image， and then it can print physical model with the company's XMQB-I human organ model 3D printing equipment and white thermoplastic. At last， preoperative evaluation and surgical plan can be made through the relationship between the tumor， organs in abdominal cavity， and abdominal vascular. During the surgery， make a comparison between the visualization results with the actual condition. Results    50 cases of patients were successfully completed the three-dimensional visualization， including 10 cases of patients completed. Three-dimensional visualization and 3D printing model can three-dimensionally， clearly show the adjacent relationship between the anatomical tumour location and surrounding organs and blood vessels， broadly in line with the actual surgery. 50 surgeries were successfully performed， no death during perioperative period. Conclusion    Three dimensional visualization and 3D printing technology can make an accurate preoperative evaluation of retroperitoneal tumors， which has a certain application value for guiding surgery.

摘要：

目的    探讨三维重建及3D打印技术在腹膜后肿瘤术前评估中的应用价值。 方法    回顾性分析2011年3月至2015年9月厦门大学附属成功医院收治的50例腹膜后肿瘤病人的临床资料，应用人体器官三维建模软件将病人的CT二维图像重建成三维可视化图像，使用人体器官模型3D打印设备，用两色热塑性塑料打印实物模型，通过观察肿瘤与腹腔器官、腹部大血管之间的关系进行术前评估并制定手术方案。实施手术，术中比较重建结果与实际的区别。 结果    50例病人均成功完成三维重建，其中10例病人完成3D打印，三维重建结果及3D打印模型能够立体、清晰和实物化的显示肿瘤解剖学位置及与周围器官、血管的毗邻关系，与术中实际情况大致相符。50例病人均顺利施行手术，术中无死亡。结论    三维重建及3D打印技术能够对腹膜后肿瘤术前进行精准评估，对指导手术具有一定的应用价值。
