“…Four basic decision-making approaches for deciding whether a simulation model is valid have been described in recent literature: 22 ( We have used the first two methods for the purposes of our research: combined verification by the development team 24 There may be several reasons that affect skill acquisition such as 2D versus 3D visual fields, training time, training models, level of supervision, as well as possible innate ability of the surgical trainee. 24 Identifying factors that ease or impede skills acquisition is key to improving the learning curve. 24 Our study addresses one such factor, i.e.…”

Background: Fundamentals in Laparoscopic Surgery (FLS) is widely used in practice for skill acquisition and objective assessments. The peg transfer model enables trainees to acquire basic laparoscopic skills. We structured three different three-dimensional (3D) peg transfer models with various heights and depths to replicate 3D laparoscopic anatomy. Before implementing any simulation model in a laparoscopy curriculum, it is important to determine its validity. Aim: To establish face and construct validity of novel 3D peg transfer models in two-dimensional (2D) and 3D visual systems for training and evaluation of laparoscopic skills in novices using the McGill inanimate system. Methods: Three peg transfer 3D models were designed with different peg heights and depths using wooden blocks from the popular game "Jenga". Ten novices, ten intermediates and ten experts were recruited. They performed three repetitions of peg transfer on each model using 3D and 2D visual modalities. Performance time, error and total score were measured. Multiple comparison (post hoc Bonferroni) tests were used to compare the data (mean value of total time, total errors and total score) for each group. All participants completed a six-question post-test questionnaire (face validity) for 2D and 3D viewing modalities. Results: When novices were compared with intermediates and experts using 2D and 3D visual systems, there were statistically significant differences (P50.001) in the total score and performance time for all models with the exception of model 2 in 2D. We were unable to show any significant difference in total score and performance time when intermediates were compared with experts with any of the three models, in either the 2D or the 3D visual modality. All models were highly rated in both visual modalities. Conclusion: Three models were developed for improving laparoscopic surgical skills. Face validity and construct validity were demonstrated by measuring significant differences in improvement of performance time and lower total score when novices were compared with intermediates and experts in both 2D and 3D visual modalities. We recommend using models 1 and 3 for simulation training in both visual modalities, and this could replace the current relatively "flat" 2D models of the FLS training course to shorten the learning curve for acquiring surgical skills.

“…The training aims to improve and transfer the skills acquired from the training lab to the operating room 8 . The programme consists of laparoscopic training modules in simulators covering pre, intra and postoperative knowledge and basic (object transfer, cut patterns, loop ligatures, knots and extracorporeal sutures) and advanced laparoscopic procedures (intracorporeal knots and sutures), with the measurement of cognitive and technical skills.…”

Abdominal cavity simulator for skill progression in videolaparoscopic sutures in Brazil

Purpose: To develop and test a model of teaching by means of an abdominal cavity simulator. Methods: This study had two stages: development of a teaching model and an experimental prospective study that aimed to evaluate the residents' competence. The participants were divided into 3 groups: first-year resident, second-year resident, and senior surgeon. The two groups of resident physicians received training in the simulator, under instructor supervision for skill acquisition, according to the model proposed in first stage. The surgeons did not receive this intervention. The correlations and associations were verified through simple and multiple linear regressions. The learning curves were analysed using Cox regression models. The impact of the epidemiological characteristics was tested. Results: All residents reached the maximum score at the end of 16 steps and were comparable to the experimental (p<0.001). Conclusion:Residents who underwent training using the methodology of the proposed teaching model, which is based on realistic simulation, acquired proficiency in the accomplishment of endosutures in up to 16 hours of training in the laboratory.

Background: Three-dimensional videosurgery is already a reality worldwide. The trainee program for this procedure should be done initially and preferably in simulators. Aim: Assemble low-cost simulator for three-dimensional videosurgery training. Methods: The simulator presented here was mounted in two parts, base and glasses. After, several stations can be inserted into the simulator for skills training in videosurgery. Results: It was possible to set up three dimensional (3D) video simulations with low cost. It has proved to be easy to assemble and allows the training surgeon of various video surgical skills. Conclusion: This equipment may be used in undergraduate programs and advanced courses for residents and surgeons. The acrylic box allows the visualization of the task executed by the tutor and even by other experienced students.
