Background This study aimed to evaluate the use of 3D image processing and reconstruction (3D-IPR) combined with virtual reality (VR) technology and printed models (PM) as teaching tools in oncological colorectal surgery. Methods We designed two courses, one for general surgery trainees and another for young colorectal surgeons, structured around stations of pre-test, anatomical lessons, real-case presentations, 3D-IPR models, VR experiences, and life-size abdominal PM with surgical approach explanations and a final post-test. Results Fourteen course participants were evaluated. Pre-test scores averaged 5.15, with a median of 5.5, while post-test scores increased to an average of 7.75, with a median score of 8. Course satisfaction surveys indicated high ratings for expectations, duration, relevance, presenter knowledge, teaching materials, communication, and overall course segments, with an average rating exceeding 4.8 out of 5. Results highlight the potential of 3D-IPR, VR, and PM as tools for improving teaching for surgery residents and colorectal surgeons. These technologies offer immersive, risk-free experiences for learners, potentially enhancing skill acquisition and anatomical understanding. Conclusion This study demonstrates the effectiveness of 3D-IPR, VR, and PM courses in improving understanding of colorectal surgery. As these technologies continue to advance, they offer enhanced immersion and accessibility, transforming surgical education and medical training.
