Abstract
Purpose
We sought to create and validate a high fidelity, anatomically correct real tissue
simulation model for thoracoscopic esophageal atresia/tracheoesophageal fistula (EA/TEF)
repair.
Methods
A scale reproduction of a neonatal rib cage was created. Surgically modified (EA/TEF)
fetal bovine tissue completed the simulator. Nine pediatric surgery fellows and two
attending pediatric surgeons (n = 11) performed the simulated thoracoscopic EA/TEF repair. Participants completed a
self-report rating scale, ranging from 1 (Don’t know) to 5 (Highly realistic). Construct
validity relevant to test content was evaluated by examining the ratings using the
many-Facet Rasch model.
Results
Analyses indicated no differences when comparing faculty (Observed Average (OA) = 4.5/5.0) to fellow (OA = 3.3) ratings, p = .71. In descending order, observed averages of the domains were 4.7 (Relevance), 4.5
(Physical attributes), 4.5 (Realism of materials), 4.4 (Ability to perform task),
and 4.2 (Value). The observed Global opinion rating indicated the simulator can be
considered for teaching thoracoscopic EA/TEF repair but could be improved slightly.
Conclusions
Fellow and faculty ratings indicated the simulator was valuable as a learning tool
with minor modifications. Comments were consistent with high physical attribute ratings.
