Proficiency-based training has become essential in the training of surgeons such that on completion they can execute complex operations with novel surgical approaches including direct manual laparoscopic surgery (DMLS) and robotically assisted laparoscopic surgery (RALS). To this effect, several virtual reality (VR) simulators have been developed. The objective of the present study was to assess and establish proficiency gain curves for medical students on VR simulators for DMLS and RALS. Five medical students participated in training course consisting of didactic teaching and practical hands-on training with VR simulators for DMLS and RALS...

BACKGROUND: Residents find it hard to commit to structural laparoscopic skills training. Serious gaming has been proposed as a solution on the premise that it is effective and more motivating than traditional simulation. We establish construct validity for the laparoscopic serious game Underground by comparing laparoscopic simulator performance for a control group and an Underground training group. METHODS: A four-session laparoscopic basic skills course is part of the medical master students surgical internship at the Radboud University Medical Centre...

BACKGROUND: Surgical training is moving away from the operating room toward simulation-based skills training facilities. This has led to the development of proficiency-based training courses in which expert performance data are used for feedback and assessment. However, few expert value data sets have been published, and no standard method for generating expert values has been adopted by the field. METHODS: To investigate the effect of different proficiency value data sets on simulator training courses, we (1) compared 2 published expert performance data sets for the LapSim laparoscopic virtual-reality simulator (by van Dongen et al...
