Abstract
BackgroundVideo surgery requires acquisition of psychomotor skills that are different from those required for open surgery. The aim of this study was to assess the EndoSuture Trainer Box Simulator (ESTBS), a new bariatric laparoscopic skills simulator, as a tool for surgical education, comparing it with a standard laparoscopic trainer (SLT).MethodsA randomized prospective crossover study was designed to compare ESTBS versus SLT as a tool for training bariatric laparoscopic skills. Participants were assigned to perform a task simulating Nissen fundoplication operation. All subjects evaluated the simulators concerning to their performance on simulating laparoscopic procedures by the use of a questionnaire comparing: triangulation, resistance and resilience, spatial perception (stereotaxy), ergonomics and positioning, inverted movements, visibility, design, technical and technological resources for training and education. The overall score was defined as the median value obtained. A total of 37 participants were enrolled in the study, including 29 experienced surgeons (78.37%) and 08 surgical residents (21.63%).ResultsA superior performance was observed with ESTBS as compared to SLT upon 7 of the 10 items evaluated in the questionnaire. Additionally, the overall score of ESTBS (median of 4, very good) was significantly higher (P < 0.0001) than that of SLT (median of 3, good). For the items, triangulation, resistance and resilience, ergonomics, design, training, technology and teaching, the evaluation for the ESTBS was very good and excellent, which was significantly higher than obtained by SLT. Also, ESTBS was cheaper.ConclusionsThe ESTBS was shown to present excellent technical and technological performances and appears to constitute a useful cost-effective promising instrument for teaching and training bariatric surgical laparoscopic skills.

EndoSuture trainer box simulator The EndoSuture Trainer Box Simulator (ESTBS) consists of a fiberglass console, similar to human stem, a hollow ring suitable for surgical anteroposterior movements with the space created corresponding to a pneumoperitoneal ambient with access to an appropriate suture tray matrix to carry on procedures and sutures, at a similar depth to that found to reach abdominal structures by operative tactic maneuvers
A total of 37 participants with different levels of laparoscopic expertise were recruited for this study, aged
Summary
Video surgery requires acquisition of psychomotor skills that are different from those required for open surgery. The aim of this study was to assess the EndoSuture Trainer Box Simulator (ESTBS), a new bariatric laparoscopic skills simulator, as a tool for surgical education, comparing it with a standard laparoscopic trainer (SLT). Moura Jr. et al [3] have developed a simulator for laparoscopic surgery upon the abdominal cavity – the EndoSuture Trainer Box Simulator (ESTBS), to apply it as an instrument of video training at a surgical teaching platform aiming to evolve and to promote technological innovation. A patent application has been deposited at the Brazilian Institute of Industrial Property under the number 1301198280 This was possible due to the experience and clinical observation gained through the handling of several other models of simulators, demonstrations of ESTBS prototypes at surgical congresses and as well as a result of the implementation of extensive continuing education training laparoscopic courses. Progressive stations simulations utilized were based upon extensive training using a SSL model with the objective of stepping up its methodology as proposed in this study
