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.
