Summary
This study introduces a 3D-printed model training protocol to improve laparoscopic Nissen fundoplication (LNF) skills. The method significantly enhances surgical proficiency and reduces complications for trainees.
Area of Science:
- Surgical Education
- Medical Simulation
- 3D Printing in Medicine
Background:
- Laparoscopic Nissen fundoplication (LNF) demands extensive surgical training.
- Early-career surgeons face a steep learning curve with potential complications.
Purpose of the Study:
- To present a structured training protocol using a 3D-printed anatomical model.
- To accelerate the acquisition of advanced laparoscopic skills for LNF.
Main Methods:
- Development of anatomically accurate, silicone-based 3D-printed models.
- Implementation of a curriculum focused on critical LNF components like suturing and crural closure.
- Pilot testing and comparative study with a control group.
Main Results:
- Pilot participant showed improved performance scores (21 to 42) and reduced procedural time (95 to 34 min).
- The 3D-printed model group achieved significantly higher OSATS scores (26.25 vs. 17.50) and shorter operative times (76.25 vs. 110.13 min).
Conclusions:
- The 3D-printed model protocol effectively enhances surgical skills for LNF.
- This validated method offers a reproducible approach to surgical skill development and assessment.
