Training in laparoscopic surgery: face validity of a low cost virtual simulator

Aim of this study is to investigate the importance of acquiring basic and advanced laparoscopic skills using a virtual reality low cost simulator in laparoscopic surgery in a defined theathre, a Medical Simulation Centre. The study shows and describes the Medical Simulation Centre in terms of utilization and activities. The article describes also the technical features of the system and its validation process about the basic skills using a primary method: the face validity. It consents to evaluate the structural simulator characteristics through a specific questionnaire, used after the system testing (we have chosen a basic skill training). A sample of 40 participants was selected: 20 post graduate students, 20 expert surgeons. The groups were divided into two homogeneous subgroups according to the level of confidence with the use of video games, consolles, smartphones (a questionnaire has been used before the practical phase of training). We analyzed the results of the face validity obtained by comparing the two groups reported impressions. The simulator appears ergonomically satisfactory and its structural features are adapted to the laparoscopic training.
