Effectiveness of an Inexpensive Short-Term, Theoretical-Practical Course on Videosurgery for Training Surgeons

Abstract Introduction: The rapid development of video surgery and minimally invasive surgical techniques prompted many studies on the methods of teaching these techniques to young surgeons in training. However, the characteristics of a short-term course that is both easily accessible and efficient for this group of surgeons remain controversial. To investigate this issue, a short-term training method was proposed for first year surgery residents, using inexpensive handmade wooden simulation boxes with the students smartphones as cameras . Its effectiveness was evaluated, as well as possible factors that could influence student performance, such as gender and previous experience with video games. Methods: 36 first-year General Surgery residents, entering in 2019 and 2020, participated in the study: 21 were males and 15 were females with ages between 22 and 29 years old, (mean 25.47 years). All participants performed a pre-established exercise (placing two simple stitches using a laparoscopic simulator), which was timed and scored. They then participated in a short theoretical-practical course, consisting of an initial lecture followed by 4 exercises on handcrafted wooden laparoscopic video surgery simulators. Afterwards, they were asked to repeat the same exercise from the first step. Finally, they answered a questionnaire that included questions on previous videogame experience. The data were tabulated and submitted to statistical analysis.Results: In the pre-training exercise, 15 (41.66%) participants were able to perform the two simple stitches in the simulator box within the maximum time limit of 5 minutes. After the short course, 22 (61.11%) of participants were able to perform the complete exercise. Improvement in the time to complete the practical exercise was statistically significant (p=0.0296) after participating in the theoretical-practical course. A better pre- and post-training performance was demonstrated by the 17 participants with experience with video games (p=0.0116), and a better post-training performance was demonstrated by female participants (p=0.0405). Conclusion: This short-term inexpensive theoretical-practical course in laparoscopic training for surgeons in training was effective in reducing the execution time of a laparoscopic stitch in a simulation box. Previous experience with video games and/or female gender appear to be associated with improved performance.
