Validation of low-cost models for minimal invasive surgery training of congenital diaphragmatic hernia and esophageal atresia

BackgroundMinimal invasive surgery (MIS) is increasingly used for the correction of congenital diaphragmatic hernia (CDH) and esophageal atresia (EA). It important to master these complex procedures, preferably preclinically, avoid complications. The aim this study was validate recently developed models train MIS procedures preclinically.MethodsTwo low cost, reproducible (one CDH one EA) were validated during several pediatric surgical conferences training sessions (January 2017–December 2018), in either LaparoscopyBoxx or EoSim simulator. Participants both completed a questionnaire regarding their opinion on realism (face validity) didactic value (content validity), rated five-point-Likert scale.ResultsOf all 60 participants enrolled, 44 evaluated EA model. All items as significantly better than neutral, with means ranging from 3.7 4.1 (p < 0.001). model by 48 participants. scored neutral (means 3.5–3.9, p 0.001), exception haptics simulated diaphragm (mean 3.3, = 0.054).
