RESUMO
BACKGROUND: Training platforms such as the Fundamentals of Laparoscopic Surgery have become an integral part of postgraduate adult general surgical education. So far, however, there is no such universal tool for pediatric minimal-invasive surgery (MIS). We therefore designed and validated a novel 3D printable pediatric MIS simulation program. METHODS: The SuSiPed (Surgical Simulation in Pediatrics) curriculum consists of 6 MIS training modules: camera guidance, shell transfer, figure cutting, cyst resection, single interrupted suturing, and slipknot suturing. All modules can be 3D printed, and thus manufactured in a low-cost, sustainable and reproducible fashion. Instructional videos for the participants for each module were created. For validation, a group of medical students and surgical residents were compared to a group of pediatric surgical specialists with experience in MIS. All participants performed the entire SuSiPed curriculum 3 times, measuring time to task completion and technical mistakes. The results of the last attempt were compared using Welch's T-test. RESULTS: There were 25 participants in the novice group and 5 in expert group. Times to task completion were lower in the expert group for all modules except camera guidance. Errors were significantly more frequent during slipknot suturing in the novice group, while there were no difference in the other modules. CONCLUSION: Our novel training platform showed good construct validity for 5 out of 6 modules, while scores of camera navigation was not associated with prior experience. The SuSiPed platform is useful for pediatric minimal-invasive surgery training and evaluation, even in low-resource countries where expensive simulators are not affordable. LEVEL OF EVIDENCE: Level III, Validation Study.
