Purpose: The need for efficient and optimal training through a structured laparoscopic training program has become increasingly evident. Virtual reality simulation may provide a safe and efficient means of acquiring laparoscopic skills. The LAP MentorTM is a high-fidelity virtual reality simulator with haptic feedback that allows a trainee to practice 9 basic laparoscopic tasks including laparoscopic suturing. The purpose of this study was to evaluate the predictive validity of performance on the LAP Mentor before surgical simulators are incorporated into training programs.
Materials and Methods: Eleven participants (6 medical students and 5 residents) underwent laparoscopic skills training on the virtual reality simulator LAP Mentor. Each participant was tested on 5 sets of 4 LAP Mentor basic laparoscopic tasks (grasping, cutting, clipping, and suturing) in a 3-week period. Total time and accuracy were measured for each task.
Results: There was a significant difference between the initial session and the final session for total time and accuracy in both groups. Among the medical students, as they progressed through the training step by step, total time decreased for the grasping task, the cutting task, the clipping task, and the suturing task. At the same time, accuracy improved for the grasping task, the cutting task, the clipping task, and the suturing task, respectively. The residents group showed a similar progression.
Conclusions: Basic skills straining on a LAP Mentor virtual reality simulator improves learning of the basic skills for laparoscopy. Education with virtual reality simulators, therefore, may provide an effective teaching method and lead to improved operating performance.
