3D-reconstruction printed models could enhance understanding of Crohn's disease complex perianal fistulas?

3D image processing and reconstruction (3D-IPR) is increasingly used in surgical applications for enhanced planning and intraoperative visualization. 3D-printed models, created from 3D-IPR, have the potential to improve understanding of anatomical structures and simulate surgical procedures. However, evidence supporting their educational benefits, particularly for complex perianal Crohn's disease (pCD) fistulas, remains limited.

This study assessed the role of 3D-printed models as teaching tools for general surgery and gastroenterology trainees/attendants. Two courses were developed, incorporating pre-tests, lessons, real case presentations with MRI scans, and discussions using 3D-printed models. Pre- and post-course test scores were analyzed to evaluate learning outcomes.

Participants demonstrated significant improvement in post-test scores compared to pre-test scores, highlighting the educational impact of 3D models. Course satisfaction surveys revealed high satisfaction, with most participants likely to recommend the course.

3D-IPR and 3D-printed models hold promise as effective tools for teaching complex pCD anatomy, enhancing surgical education, and improving understanding of 3D structures. These findings enhance the growing importance of integrating 3D technologies into modern surgical training.
