“…Playing music in the OR is a noninvasive intervention of negligible cost. [27][28][29][30] In the context of the international drive toward objective measurable competency-based training outcomes, motion analysis technology may increasingly prove to be an important tool for training as the nature of surgical residency and assessment continues to evolve. 8 We also demonstrated the broad applicability of motion analysis to better understand factors that may lead to enhancements in microsurgical training.…”

“…Before training, all motion metrics parameters in AR correlated highly with BLS score, further validating the motion metrics as valuable assessment tools. 29 Two of 3 AR metrics (time and economy of movement) were also able to detect improvements in performance after training. By contrast, none of the OSATS evaluation tools correlated with BLS score.…”

The simulated surgical procedure was divided into 7 steps: (1) positioning of the instrument; (2) identification of the anatomical structures including gallbladder fundus and neck, cystic duct and artery, and common bile duct.…”

“…6,9,22 Live animal or cadaver models are high fidelity and useful training and assessment tools, 13,28 but are sparsely available, very expensive, and the ethical concern of training in live animals remains an important aspect. A recent study showed the value of motion metrics in evaluation of laparoscopic skills in veterinary medicine, 29 yet the effect of low vs high fidelity models in training remains controversial.…”

Objective: To compare the effects of 2 training curricula on laparoscopic skills and performance of simulated surgery in veterinary students.Study design: Prospective study.Sample population: Veterinary students (n 5 33) with no prior hands-on experience in minimally invasive surgery.Methods: Basic laparoscopic skills (BLS) were assessed based on 5 modified McGill inanimate system for training and evaluation of laparoscopic skills. Motion metrics and an objective structured assessment of technical skills (OSATS) were used to evaluate surgical skills during a simulated laparoscopic cholecystectomy performed in an augmented reality simulator. Students were randomly assigned to either skill-based (group A) or procedural-based (group B) training curriculum. Both tests were performed prior to and after a 10-session training curriculum.Results: Post-training BLS results were improved in both training groups (P < .001). Seven participants completed both presimulated and postsimulated laparoscopic cholecystectomy, preventing paired analysis. Based on motion metrics analysis, participants completed tasks in a shorter time (P 5 .0187), and with better economy of movement (P 5 .0457) after training. No difference was detected in OSATS before and after training.Conclusion: Both training curricula improved BLS, but significant differences were not detected between the procedural-based training program and basic skills training alone in veterinary students. Motion metrics such as time, economy of movement, and instrument path were superior to an OSATS, when assessing surgical performance. Further studies are needed to compare the effects of different simulators on the training of veterinarians with diverse laparoscopic surgical experience. | I NT ROD UCTI ONMinimal invasive surgery (MIS) results in less pain and faster recovery for animal patients 1-5 but requires different surgical skills than traditional open surgery. 6,7 Surgeons need to overcome the fulcrum effect, adjust hand-eye coordination, altering the approaching angle of instruments, and adjust to a more restricted field of view. 8 The surgical mantra "see one, do one, teach one" is not suitable in laparoscopic surgery. 9 In the past 2 decades, interest in simulation training and assessment has grown, to surmount the training obstacle in MIS, in animals and man. [8][9][10][11][12][13][14] Simulation aims to replicate clinical situations, ranging from low fidelity simulated basic skills training, to very realistic surgical simulations in high fidelity models. Accordingly, health educators in human medicine have adopted simulation as a viable educational method to teach and practice a diverse range of clinical skills. Live animal or cadaver models are high fidelity and useful training and assessment tools, 13,28 but are sparsely available, very expensive, and the ethical concern of training in live animals remains an important aspect.
