3D printing has been increasingly used to create accurate patient-specific 3D-printed models from medical imaging data. We aimed to evaluate the utility of 3D-printed models in localization and understanding of pancreatic cancer for surgeons before pancreatic surgery.

Materials and Methods:
Between March and September 2021, we prospectively enrolled 10 patients with suspected pancreatic cancer who were scheduled for surgery. We created an individualized 3D-printed model from preoperative CT images. Six surgeons (three staff and three residents) evaluated the CT images before and after presentation of the 3D-printed model using a 7-item questionnaire (understanding of anatomy and pancreatic cancer [Q1 – 4], preoperative planning [Q5], and education for trainees or patients [Q6 – 7]) on a 5-point scale. Survey scores on Q1 – 5 before and after the presentation of the 3D-printed model were compared. Q6 – 7 assessed the 3D-printed model’s effects on education compared to CT. Subgroup analysis was performed between staff and residents.

Results: After the 3D-printed model presentation, survey scores improved in all five questions (before 3.90 vs. after 4.56, p<0.001), with a mean improvement of 0.57?0.93. Staff and residents scores improved after 3D-printed model presentation (p<0.05), except for Q4 in the resident group. The mean difference was higher among the staff than among the residents (staff: 0.50?0.97 vs. residents: 0.27?0.90). The scores of the 3D-printed model for education were high (trainees: 4.47 vs. patients: 4.60) compared to CT.

The 3D-printed model of pancreatic cancer improved surgeons’ understanding of individual patients’ pancreatic cancer and surgical planning.
