Training minimally invasive surgery's basic skills: is expensive always better?

Results of a Novel Long-Term Method for Laparoscopic Skills Online Training

Introduction: Ensuring patient safety in minimally invasive surgery (MIS) within the field of pediatric surgery requires systematic and extensive practice. Many groups have proposed mastery learning programs encompassing a range of training methods. However, short courses often have a narrow focus on specific objectives, limiting opportunities for sustained training. Our aim was to analyze our results with an online long-term competency-based and supervised training. Methods: This is a retrospective cohort study with prospective data collection of scores and performance of trainees during online courses from October 2020 to April 2023. Results: All participants (n = 76) were able to set up their personal training gym and complete the intensive stage of the course. The total score evolved from 2.60 ± 0.56 at the first meeting to 3.67 ± 0.61 at the fourth meeting, exhibiting a significant difference (P < .013). A considerable drop out was observed in the follow-up stage, with only 53.8% of the participants completing the course. When compared with the first meeting, they also showed a significant improvement with a mean general score of 3.85 ± 0.25 (P < .013) Conclusion: We have presented a novel online training program, based on continuous training that demonstrated that the unlimited access to a personal training gym allows surgeons to improve and maintain MIS skills.

Development and validation of a low-cost laparoscopic simulation box

INTRODUCTION

The acquisition of laparoscopic technique skills in an operating room is conditioned by the expertise of the tutor and the number of training interventions by the trainee. For students and surgeons to use a laparoscopic simulator to train their skills, it must be validated beforehand.

METHODS

A laparoscopic simulator box was designed, along with 6 interchangeable training games. The simulator was validated by a group of 19 experts, physicians with an experience from at least 100 laparoscopic surgeries, and 20 students of 4^th to 6^th grades of medical school (non-experts). To evaluate its construct validity, time-to-completion and the number of successfully completed games were assessed. We used 11 and 9-item questionnaires to gather information on content and face validity respectively. In both questionnaires, answers were collected through Likert-type scales, scored from 1 to 5.

RESULTS

The group of experts required less time and successfully completed more games than the group of non-experts (p < 0.01). The group of non-experts gave a score ≥ 4 points on each of the questions regarding the content validity of the tool, however, the experts rated with a significant lower mean score the need for the simulator to learn the surgical technique (3.68 points; p < 0.01). Regarding the face validity, all items were graded with a score ≥ 4 points except for the question relating to the spatial realism (3.82 points).

CONCLUSION

The laparoscopy simulation box and the games were valid means for training surgeons and medical students to develop the skills required for the laparoscopic technique.

Distance Education for Basic Surgical Skills Using Homemade Tools—DIY Methods for Emergency Situations

The aim of our research was to establish a reproducible curriculum that offers the possibility to gain basic surgical skills (knot tying, suturing, laparoscopy basics) through distance education in emergency situations by using tools available in the household. Forty-six volunteering third- and fourth-year medical students were involved in the study. The distance education system was set up using homemade or easily obtainable tools (an empty can, shoe box, sponge, etc.) to teach surgical knotting, suturing, and basic laparoscopic skills. The reachable learning objectives were contrasted with the original course plan. Feedback from the students has been collected. The students’ results were compared to the regular course of the previous years. Seventy-nine percent of the original learning objectives could be reached completely, and 15% partially. The necessary tools were available for 82% of the students. The students evaluated the course for 4.26 in general and 4.86 considering the circumstances (on a 5-level-scale). The homemade trainers were assessed over four as an acceptable substitution. Students’ exam results decreased only by 7% compared to the previous two years. Basic surgical skills can be educated with acceptable efficiency and student satisfaction using distance teaching and homemade tools. This is the first study where not only the simulators but the surgical instruments were replaced with household tools and evaluated by a reproducible curriculum.
