In brief
This validation study demonstrates that low-cost simulation models for laparoscopic repair of congenital diaphragmatic hernia and esophageal atresia are effective training tools. Sixty pediatric surgeons evaluated the models during conferences, rating both face and content validity significantly above neutral, confirming their utility for preclinical skill development in complex neonatal procedures.
Written by the GCMD Library team from the article.
Background: Minimal invasive surgery (MIS) is increasingly used for the correction of congenital diaphragmatic hernia (CDH) and esophageal atresia (EA). It is important to master these complex procedures, preferably preclinically, to avoid complications. The aim of this study was to validate recently developed models to train these MIS procedures preclinically.
Methods: Two low cost, reproducible models (one for CDH and one for EA) were validated during several pediatric surgical conferences and training sessions (January 2017-December 2018), used in either the LaparoscopyBoxx or EoSim simulator. Participants used one or both models and completed a questionnaire regarding their opinion on realism (face validity) and didactic value (content validity), rated on a five-point-Likert scale.
Results: Of all 60 participants enrolled, 44 evaluated the EA model. All items were evaluated as significantly better than neutral, with means ranging from 3.7 to 4.1 (p < 0.001). The CDH model was evaluated by 48 participants. All items scored significantly better than neutral (means 3.5-3.9, p < 0.001), with exception of the haptics of the simulated diaphragm (mean 3.3, p = 0.054). Both models were considered a potent training tool (means 3.9).
Conclusion: These readily available and low budget models are considered a valid and potent training tool by both experts and target group participants.
