Summary
A novel, low-cost 3D-printed laparoscopic trainer (SCLT) demonstrated comparable learning speeds to standard trainers for pediatric surgical residents. This accessible tool can improve laparoscopic training, especially in resource-limited settings.
Area of Science:
- Medical Education
- Surgical Training
- 3D Printing Technology
Background:
- Laparoscopic surgery requires specialized training tools.
- Standard laparoscopic trainers can be expensive and inaccessible.
Purpose of the Study:
- To create and evaluate the face validity of a novel, low-cost, 3D-printed pediatric laparoscopic trainer (SCLT).
- To compare the SCLT's effectiveness against a standard laparoscopic trainer (LT) for surgical residents.
Main Methods:
- Developed the SCLT using fused deposition modeling (cost: €5, assembly: 10 min).
- Evaluated performance of surgeons and residents on SCLT and LT using Objective Structured Assessment of Technical Skill (OSATS) and time.
- Assessed learning speed via a non-inferiority test comparing SCLT to LT.
Main Results:
- The SCLT showed a similar learning speed compared to the standard LT (ratio: 1.10, p=0.09 for non-inferiority).
- Resident performance on the SCLT was comparable to the LT.
Conclusions:
- The SCLT is a viable, cost-effective alternative for pediatric laparoscopic training.
- Widespread adoption of the SCLT can enhance access to laparoscopic skills development, particularly in developing countries.
