Development of a structured virtual reality curriculum for laparoscopic appendicectomy - 09/04/20
Abstract |
Background |
Laparoscopic appendicectomy (LA) is a common surgical emergency procedure mainly performed by trainees. The aim was to develop a step-wise structured virtual reality (VR) curriculum for LA to allow junior surgeons to hone their skills in a safe and controlled environment.
Methods |
A prospective randomized study was designed using a high-fidelity VR simulator. Thirty-five novices and 25 experts participated in the assessment and their performances were compared to assess construct validity. Learning curve analysis was performed.
Results |
Five of the psychomotor tasks and all appendicectomy tasks showed construct validity. Learning was demonstrated in the majority of construct-valid tasks. A novel goal-directed VR curriculum for LA was constructed.
Conclusions |
A step-wise structured VR curriculum for LA is proposed with a framework which includes computer generated metrics and supports deliberate practice, spacing intervals, human instruction/feedback and assessment. Future study should test the feasibility of its implementation and transferability of acquired skill.
