PURPOSE: Thoracoscopic esophageal atresia/tracheoesophageal fistula (EA/TEF) repair in neonates is technically difficult because of the small working space and fragility of tissues. This study aimed to show the construct validity of the neonatal EA/TEF simulator by video-based assessment of endoscopic suturing skill.
MATERIALS AND METHODS: A rapid-prototyped neonatal chest model with an artificial esophagus model similar to the actual neonatal esophagus was developed. Forty pediatric surgeons performed an endoscopic intracorporeal suturing task and a knot-tying task using the model, and a questionnaire survey was administered. Each task was video recorded and assessed using two skill assessment methods (the 29-point checklist method and the error assessment sheet method). The task completion time and the number of manipulations were measured.
RESULTS: With regard to experience in performing thoracoscopic TEF repair, the experienced surgeons (ESs, ≥3 EA/TEF repair experiences, n = 6) were significantly superior to the inexperienced surgeons (ISs, <3 experiences, n = 34) in all metrics. Upon comparison by the pediatric Endoscopic Surgical Skill Qualification (ESSQ) status, there were no significant differences in all metrics between the ESSQ-qualified (n = 15) and nonqualified (n = 25) surgeons. The qualified ESs (n = 6) were significantly superior to the qualified ISs (n = 9) in all metrics.
CONCLUSION: Video-based endoscopic surgical skill assessment using the neonatal EA/TEF simulator could differentiate ESs from ISs. The construct validity of the simulator was demonstrated, and the simulator would be useful especially for practicing thoracoscopic EA/TEF procedures.
