Summary
A new pediatric laparoscopic surgery (PLS) simulator was developed and validated. This tool effectively differentiates between novice, intermediate, and expert surgical skills, enhancing pediatric surgical training.
Area of Science:
- Surgical Simulation
- Pediatric Surgery
- Medical Education
Background:
- Lack of a validated simulator for pediatric laparoscopy contrasts with existing adult simulators.
- Development of a pediatric laparoscopic surgery (PLS) simulator is crucial for training.
Purpose of the Study:
- To develop and validate a novel pediatric laparoscopic surgery (PLS) simulator.
- To assess the simulator's ability to differentiate surgical skill levels.
Main Methods:
- A PLS simulator was created and tested.
- Participants were grouped by expertise (novice, intermediate, expert).
- Testing involved the Fundamentals of Laparoscopic Surgery (FLS) and PLS simulators.
Main Results:
- PLS intracorporeal suturing scores were lower than adult benchmarks (P = .02).
- PLS pattern-cutting scores exceeded FLS simulator scores (P < .001).
- Total PLS scores differentiated between skill levels in 3 of 5 tasks.
Conclusions:
- The PLS simulator demonstrates construct validity by distinguishing skill levels.
- Further refinement of 2 tasks or scoring metrics is needed for full validation.
