q2 i? The Pediatric Laparoscopic Surgery (PLS) simulator was the most commonly used model, appearing in 7 of 20 studies, with construct validity established for its pattern-cutting task through modified scoring metrics. → Zahradníková Petra 2025

q2 · i? · review · r2

Systematic review synthesis of 20 studies describing 9 neonatal/infant simulation models. The review reports the PLS simulator "was by far the most commonly used, appearing in 7 studies" and that construct validity was established for its pattern-cutting task.

"The Pediatric Laparoscopic Surgery Simulators (PLS) were by far the most commonly used, appearing in 7 studies, while 3D-printed synthetic models were used in 5 studies. Preliminary data from Nasr et al. [8], Azzie et al. [14] and Retrosi et al. [15] suggest that PLS simulator remains the only validated tool for pediatric MIS, with construct validity established for its pattern-cutting task through modified scoring metrics that improved differentiation among skill levels."
