In brief
This study validates motion-tracking technology as an objective method to assess surgical skill acquisition using a high-fidelity 3D-printed simulator for neonatal thoracoscopic EA/TEF repair. Instrument path length metrics successfully differentiated surgeons by expertise level during simulated intracorporeal suturing tasks.

Introduction
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.
Methods
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
