Effectiveness of an Eight-Week Simulation-Based Laparoscopic Training Program for Coloproctology Residents: A Prospective Pretest–Posttest Study
This prospective pretest–posttest study demonstrates that an eight-week structured Fundamentals of Laparoscopic Surgery (FLS) simulation-based training program significantly improves laparoscopic technical skills among coloproctology residents in Mexico, supporting the integration of standardized simulation curricula into Latin American surgical residency programs.

Surgery has long been a craft learned by watching and doing, but the tools of the trade have changed dramatically. For decades, surgeons made large incisions to reach inside the body, relying on direct vision and their own hands to manipulate tissues. Today, many procedures are performed through tiny keyholes using long, thin instruments and a camera. This approach, known as laparoscopic surgery, offers patients faster recovery times, shorter hospital stays, and less inflammation. However, learning to operate through these small openings is far more difficult than traditional surgery. The surgeon must move their hands while watching a two-dimensional screen, a task that feels unnatural and requires a unique set of hand-eye coordination skills that cannot be easily picked up just by watching a master surgeon. Because practicing these complex movements on real patients carries risks, medical educators have turned to simulation. These are training boxes that mimic the operating room environment, allowing trainees to repeat specific movements until their muscles learn the correct patterns without ever touching a patient.
In Mexico, a team of researchers at the Hospital Civil de Guadalajara set out to test whether a structured, eight-week training program could successfully teach these difficult skills to residents specializing in coloproctology, the branch of medicine dealing with the colon and rectum. They focused on a specific, internationally recognized curriculum called the Fundamentals of Laparoscopic Surgery. This program breaks down the complex act of laparoscopic surgery into five basic exercises: moving small pegs from one place to another, cutting a shape with extreme precision, tying a loop of string, and sewing inside and outside the body. The researchers wanted to see if dedicating two months to practicing these specific tasks would actually make the residents better surgeons. They also investigated two common questions that often come up in surgical training: does having played video games as a hobby help a surgeon learn these skills faster, and does having already spent time in the operating room before the training give a student a head start?
The study involved fourteen residents, split evenly between first-year and second-year trainees. Before the training began, the researchers measured their baseline skills by having them perform the five exercises on a simulator. They recorded how long each task took and counted any mistakes, such as dropping a peg or cutting outside the marked line. The residents then spent eight weeks practicing these tasks on the simulators. At the end of the program, they took the same test again. The results were striking. Every single resident showed significant improvement. The time it took to move the pegs dropped from an average of 336 seconds down to 146 seconds. The number of times they dropped the objects fell to almost zero. In the precision cutting task, where no one had managed to cut within the marked lines before the training, every single participant succeeded after the eight weeks. The same pattern held true for the more difficult tasks of tying loops and sewing; the time required to complete them decreased dramatically, and the accuracy of the knots and stitches improved so that nearly all residents could now tie a secure knot, a feat only 28% of them could manage before the training.
The researchers also looked at the personal habits of the trainees to see if they influenced the results. They asked the residents how often they played video games. While it is a popular idea that video gamers might have better hand-eye coordination, the data showed no difference in performance between those who played video games frequently and those who did not. Whether a resident played video games three times a week or never touched a controller, their improvement in the simulator was the same. However, a different factor did matter. The residents who reported having prior experience in the operating room, specifically participating in laparoscopic procedures at least three times a week, started the training with higher skill levels than those who had not. They completed tasks faster and made fewer errors right from the beginning. This suggests that while the training program was effective for everyone, actual time spent in the operating room provides a tangible advantage that simulation alone cannot instantly replicate.
The study concludes that a structured, eight-week simulation program is a highly effective way to teach the fundamental skills of laparoscopic surgery to coloproctology residents. The training successfully transformed novices into competent practitioners of these basic tasks, proving that deliberate, repetitive practice in a safe environment works. The findings support the idea that medical schools and residency programs should include these standardized simulation curricula early in training to ensure patient safety. While video game habits did not predict success, the value of real-world exposure remained clear, indicating that the best preparation combines both simulated practice and supervised time in the operating room. This research provides a clear path forward for surgical education in Latin America and beyond, showing that with the right training tools, the difficult art of laparoscopic surgery can be mastered systematically.
