Development and assessment of a simulation-based curriculum in pediatric surgical education: Conventional wisdom and lessons learned from the national training program in France

Advances in Pediatric Surgery Simulation-Based Training

Pediatric surgery is the diagnostic, operative, and postoperative surgical care of children with congenital and acquired anomalies and diseases. The early history of the specialty followed the classic "see one, do one, teach one" philosophy of training but has since evolved to modern methods including simulation-based training (SBT). Current trainees in pediatric surgery face numerous challenges, such as the decreasing incidence of congenital disease and reduced work hours. SBT consists of several modalities that together assist in the acquisition of technical skills and improve performance in the operating room. SBT has evolved to incorporate simulator models and video gaming technology, in parallel with the development of simulation in other surgical and non-surgical pediatric fields. SBT has advanced to a level of sophistication that means that it can improve the skills of not only pediatric surgery trainees but also practicing attending surgeons. In this review, we will discuss the history of pediatric surgery, simulation in pediatric surgery training, and the potential direction of pediatric surgical simulation training in the future.

Development and Validation of a Laparoscopy Simulation Model of Pyeloplasty for Pediatric Patients

Introduction: Given the extensive training required for laparoscopic pyeloplasty and the difficulties achieving this training, there is a need to recreate the activity in a controlled environment, but high-fidelity models are unavailable or expensive. Our objective was to develop a model of pyeloureteral junction stenosis, resembling the anatomical details and consistency of natural tissue, for a replicable, cheaper, and realistic simulation model of laparoscopic pyeloplasty in children. Materials and Methods: A three-dimensional, printed synthetic model was created from magnetic resonance urography. The model comprises a plastic kidney as the reusable structure and a silicone renal pelvis and ureter as the interchangeable structure. We evaluated realism and performance with surgeons and residents at different levels of training, comparing operative time and complications of the procedure. Results: Twenty-four participants were recruited; 41.7% had previous experience in laparoscopic pyeloplasty, with 5.5 years of experience in laparoscopic surgery (interquartile range [IQR] 2-7.75). There were no cases of stenosis, but leaks accounted for 41.7%. The procedure lasted 72 minutes (IQR 55-90), with significant differences according to the level of training (85 minutes for residents, 68 minutes for pediatric surgeons and urologists, and 40 minutes for laparoscopic surgeons; P: .011) and years of previous experience in laparoscopic surgery (P: .003). Conclusions: A high-fidelity, replicable, and low-cost pyeloureteral stenosis model was developed to simulate laparoscopic pyeloplasty in pediatric patients.
