Summary
A new laparoscopic fundoplication simulator effectively differentiates surgeon skills. Pediatric surgery experts demonstrated superior suturing accuracy and bimanual coordination compared to trainees, validating the simulator for surgical skill assessment.
Area of Science:
- Surgical simulation
- Medical education technology
- Laparoscopic surgery training
Background:
- Laparoscopic fundoplication requires specialized skills.
- Objective assessment tools are crucial for surgical training.
Purpose of the Study:
- To develop and validate a laparoscopic fundoplication simulator.
- To assess and differentiate surgical skills using an objective evaluation system.
Main Methods:
- A pediatric laparoscopic fundoplication simulator was created using infant CT data.
- Pediatric surgery experts (PSE), pediatric surgery trainees (PSN), and general surgeons (GS) performed simulated Nissen wraps.
- Surgical performance was evaluated based on time, suture symmetry, suture interval uniformity, and bimanual coordination (forceps path length and velocity).
Main Results:
- Pediatric surgery experts (PSE) showed significantly better performance than trainees (PSN) in total time and path length (p < 0.01).
- General surgeons (GS) exhibited faster forceps usage, while trainees (PSN) showed faster right than left forceps use (p < 0.05).
- PSE demonstrated superior suture symmetry and shorter total path length compared to general surgeons (GS) (p < 0.01).
Conclusions:
- The developed simulator effectively validates skill differences between general surgeons and pediatric surgeons.
- Both pediatric surgery experts and general surgeons exhibit excellent bimanual coordination, surpassing trainees.
- Pediatric surgery experts performed highly accurate and precise maneuvers in a simulated confined operative space.
