Acquiring the technical skills required for thoracoscopic repair of esophageal atresia with tracheo-esophageal fistula (EA/TEF) is challenging. A high-fidelity 3D-printed pediatric thoracoscopic EA/TEF simulator has been developed to address this issue. This study explored motion-tracking as an assessment tool to distinguish between surgeons of different expertise using the simulator.
Participants performed a single intracorporeal suture between the esophageal ends in EA with TEF. Total relative path lengths of the right and left surgical instruments were recorded during the task. Each video-recorded attempt was assessed by a blinded pediatric surgeon using a modified Objective Structured Assessment of Technical Skills (OSATS) score. Data recorded as median (range) and statistical significance as p
