The Application Of 3D Printout Models On Pancreatic Cancer Surgery

Objective:To explore the application about the 3D Printout Models on Pancreatic Cancer Surgery.Methods:A total of 20 cases about Pancreatic Cancer Surgery which using 3D Printout Models during Jan.2014 to Dec.2015. We collect the CT imaging data and to produce the 3D printout models. Then a total of 30 surgical residents were randomly divided into 2 groups. Residents in the experiment group (n= 15) reviewed 3D-printed models, whereas in the control group, residents (n= 15) reviewed 3D computer models. Both groups subsequently completed an examination to assess the appropriateness of their preoperative plan and provide a numerical score of the quality of the surgical plan. Collect relevant data and analysis the application about the 3D Printout Models on Pancreatic Cancer Surgery.Results:Residents in the experiment group showed significantly higher quality of the surgical plan scores compared with residents in the control group (76.4 ± 10.5 vs.66.5± 11.2, p<0.05). This difference was due in large part to a significant difference in QSP-b scores (22.1 ± 2.9 vs.17.4 ± 4.2, p<0.05) between each group. A total 20 cases, ratio of radical surgery is 75%; To eliminate the palliative surgery cases, remaining 15 cases, time of operation is 247±71 min, mean bleeding volume is 296±189 ml, ratio of ICU stay is 20%, time of catheter removing is 4.67±2.47 days, time of stomach tube removing is 5.00±1.77 days, time of start enteral nutrition is 6.07±1.67 days, hospital stays after operation is 16.0±4.5 days; The ratio of postoperative complications is 13%.Conclusion:3D Printout Models can better evaluate and plan the pancreatic cancer, and may improve the safety of the pancreatic cancer in clinical practice.
