Objective: To evaluate the impact of 3-dimensional (3D) digital and printed models on minimally invasive gynecologic surgeons’ operative plan, outcomes, and experience.Methods: Using a prospective, cross-sectional, repeated measures design, we are recruiting Minimally Invasive Gynecology (MIG) surgeons (n=6) at The Ottawa Hospital (TOH) and their respective surgical candidates (n=50). Using our team’s 3D printing protocol, patient-specific 3D digital and printed models are produced from cross-sectional Magnetic Resonance (MR) images. Surgeons complete a pre-operative questionnaire before and after viewing the models. They are given the opportunity to consult the models intra-operatively, and finally complete a post-operative questionnaire. Chi-square test of independences, Mann-Whitney U, and dependent T-tests will be used to evaluate significant differences between variables related to surgical plan before and after viewing models, and descriptive statistics to evaluate surgeon experience. Results: Two cases have been completed to date. The first was a proof of concept to establish our 3D printing and study protocols. In this case, a 3D model of a multifibroid uterus was printed for myomectomy planning in a 42-year-old G0P0 with significant bulk symptoms. In the second case, a 3D model was printed to plan for myomectomy in a 45-year-old G5P1 with future fertility goals. Viewing the 3D digital and printed models affected the surgeons’: planned hemostatic techniques, perceived surgical complexity, allocated operative time, anticipated risk of complications, surgical confidence, and positively impacted their surgical experience. Conclusion: Patient-specific 3D models increase understanding of complex anatomy in gynecologic surgery, optimizing pre-operative planning, intra-operative performance, surgeon experience, and patient outcomes.
