The Feasibility of Practical Training in Minimally Invasive Surgery at Medical School-A Prospective Study on the Pelvitrainer.

Background and Objectives: The acquisition of practical skills at medical school is an important part of the multidimensional education program of future physicians. However, medical schools throughout the world have been slow in incorporating practical skills in their curriculum. Therefore, the aims of the present prospective study were (a) to demonstrate the feasibility of such surgical training, (b) to objectify its benefit in medical education, and (c) to investigate the impact of such training on subsequent career choices. Material and Methods: We introduced a two-day laparoscopy course on the pelvitrainer as part of the curriculum of the gynecological internship of fifth year medical students from 2019 to 2020. The results of the students' training were matched to those of surgeons who completed the same curriculum in a professional postgraduate laparoscopy course from 2017 to 2020 in a comparative study design. Additionally, we performed a questionnaire-based evaluation of the impact of the course on medical education and subsequent career choices directly before and after completing the course. Results: A total of 261 medical students and 206 physicians completed the training program. At baseline, the students performed significantly more poorly than physicians in a median of three of four exercises (p < 0.001). However, this evened out in the final runs, during which students performed more poorly than physicians only in one exercise and even better than physicians in one. The general integration of surgical training in medical school curricula was rated very low (12.4% on the VAS, IQR 3-16%) despite the high demand for such training. In the survey, the course was deemed very beneficial for medical education (median VAS 80.7%, IQR 73-98%), but did not appear to influence the students' subsequent career preferences. Conclusions: The acquisition of practical surgical skills during medical school is significantly under-represented in many medical faculties. The benefits of such training, as demonstrated in our study, would improve the education of future physicians.

Factors influencing surgical performance and learning progress in minimally invasive surgery - results of an interdisciplinary multicenter study.

BACKGROUND: Advancing surgical techniques require a high level of adaptation and learning skills on the part of surgeons. The authors need selection procedures and decision support systems for the recruitment of medical students and young surgeons. The authors aimed to investigate factors influencing the surgical performance and learning abilities of surgeons and medical students. MATERIALS AND METHODS: The training scores of persons attending 16 standardized training courses (at three training centers) of the German Working Group for Gynecological Endoscopy (AGE e.V.) from 2017 to 2020, individual characteristics, and the results of psychomotor tests of three-dimensional imagination and hand-eye coordination were correlated. Similar analyses were performed for medical students in their final clinical year from 2019 to 2020. The training concept was evaluated in a prospective, multicenter, interdisciplinary, multinational setting. RESULTS: In all, 180 of 206 physicians (response rate 87.4%) and 261 medical students (response rate 100%) completed the multistage training concept successfully. Of personal characteristics, the strongest correlation was noted for good surgical performance and learning success, and the absolute number of performed laparoscopic surgeries ( r =0.28-0.45, P <0.001/ r =0.1-0.28, P <0.05). A high score on the spatial visualization ability test was also correlated with good surgical performance ( r =0.18-0.27, P <0.01). Among medical students with no surgical experience, however, age was negatively correlated with surgical performance, that is the higher the age, the lower the surgical performance ( r =0.13/ r =0.22, P <0.05/ P <0.001). CONCLUSION: Individual factors (e.g. surgical experience, self-assessment, spatial visualization ability, eye-hand coordination, age) influence surgical performance and learning. Further research will be needed to create better decision support systems and selection procedures for prospective physicians. The possibilities of surgical training should be improved, promoted, and made accessible to a maximum number of surgical trainees because individual learning curves can be overcome even by less talented surgeons. Training options should be institutionalized for those attending medical school.

The pelvitrainer for training in laparoscopic surgery - A prospective, multicenter, interdisciplinary study: Experimental research.

BACKGROUND: Minimally invasive surgical procedures have a flat learning curve, especially in the initial period of a surgeon's training. Pelvitrainers enable the prospective surgeon to drill the surgical technique, including camera navigation, instrument manipulation, and the individual steps of the operation, on a model rather than a patient. Integrating the pelvitrainer into standardized surgical training programs is challenging, but would be essential to achieve optimum effects of long duration in surgical education. MATERIAL AND METHODS: The pelvitrainer Realsimulator 2.0 (Endodevelop) was evaluated in 16 standardized training courses (at three training centers) of the German Working Group for Gynecological Endoscopy (AGE e.V.) from 2017 to 2020, The training concept was implemented and evaluated in a prospective, multicenter, interdisciplinary, multinational setting. RESULTS: One hundred and eighty of 206 physicians (response rate 87.4%) completed the multi-stage training concept successfully. A significant (p < 0.001) objective improvement (positive learning curve) was observed for all exercises on the pelvitrainer. The trainer's subjective evaluation revealed positive ratings for design (median 82%, IQR 71-91%), camera navigation (87%, IQR 76-95%), and instrument manipulation (median 87%, IQR 77-94%). A follow-up survey performed six months after the course confirmed its sustainable and high benefits in clinical routine (median 82%, IQR 70-97%). CONCLUSION: The present investigation proved the high educational value of pelvitrainers, which can be enhanced by using a structured training concept. The benefit of training courses for health care justifies their incorporation into a standardized training curriculum. The completion of such training courses should be regarded as a prerequisite for a doctor to qualify as an independent surgeon.
