Which Imaging Modality Is Superior for Prediction of Response to Neoadjuvant Chemotherapy in Patients With Triple Negative Breast Cancer? J. Atkins, A. Cyr, C. M. Appleton, C. S. Fisher, J. A. Margenthaler; Washington University School of Medicine, St. Louis, MO 48.5. Does A Concomitant Ventral Hernia Repair Increase the Morbidity of A Panniculectomy? A. Y. Zemlyak, P. D. Colavita, S. El Djouzi, A. L. Walters, L. Hammond, B. Hammond, V. Tsirline, S. Getz, B. T. Heniford; Carolinas Medical Center, Charlotte, NC VR-based camera navigation curriculum is currently available. We developed and implemented a novel curriculum on the LapSimÔ VR simulator platform for our residents and students. We hypothesize that our curriculum will demonstrate construct and face validity in our trainee population, distinguishing levels of laparoscopic experience as part of a realistic training experience. Methods: Overall, 41 participants with various levels of laparoscopic training completed the curriculum. Participants included medical students, surgical residents (PGY 1-5), fellows and attendings. Subjects were stratified into three groups (novice, intermediate, or advanced) based on previous laparoscopic experience. Face validity was assessed with questionnaires. the proficiency-based curriculum consists of three modules, which include camera navigation, coordination, and target visualization using 0 and 30 degree laparoscopes. Metrics include time, target misses, drift, path length, and tissue contact. Data were analyzed using ANOVA and student’s t-test. Results: Significant differences were noted in repetitions required to complete the curriculum; 41.8 for novices, 21.2 for intermediates and 11.7 for experts (p<0.05) (Figure). in the individual modules, coordination required 13.3 attempts for novices, 4.2 for intermediates and 1.7 for experts (p<0.05). Target visualization required 19.3 for novices, 13.2 for intermediates and 8.2 for experts (p<0.05). Participants believe the training improves camera handling skills (95%), is relevant to surgery (95%), and is a valid training tool (93%). Graphics (98%) and realism (93%) were highly regarded. Conclusions: The VR-based camera navigation curriculum demonstrates construct and face validity for our training population. Camera navigation simulation should be integrated into training protocols for residents and medical students.
