Abstract
BACKGROUND: Considerable resources have been invested in low- and high-fidelity simulators in surgical training. To our knowledge, no investigation has compared the 2 head to head for operative assessment purposes. The purpose of this study was to assess the Fundamentals of Laparoscopic Surgery (FLS) low-fidelity video trainer and LapVR (high-fidelity virtual-reality simulator) for (1) construct and (2) predictive validity using a human cholecystectomy model. METHODS: Twenty-six participants performed tasks from the FLS program and the LapVR simulator as well as a human laparoscopic cholecystectomy. Performance was evaluated using FLS and LapVR metrics and the Objective Structured Assessment of Technical Skills previously validated rating scale. RESULTS: Construct and predictive validity were strongly demonstrated for FLS tasks but only incompletely for LapVR. CONCLUSIONS: Efforts should be focused on using the well-validated lower-cost FLS video trainer for assessment of laparoscopic skills. The high-cost LapVR remains experimental in resource-constrained training programs.
