Summary
This study outlines a microsurgery training program using rat models, showing improved surgical times and outcomes with practice. Standardized microsurgical training is recommended for better results.
Area of Science:
- Veterinary Surgery
- Surgical Education
- Microsurgery Techniques
Background:
- Microsurgery requires specialized training for proficiency.
- Assessing learning curves is crucial for optimizing surgical education.
Purpose of the Study:
- To detail a basic microsurgery training program.
- To evaluate the learning curve through operating times and functional outcomes.
Main Methods:
- A training program incorporating basic, transitional, and experimental models was developed.
- Procedures included tail vein cannulation, intestinal resection and anastomosis, and major vessel anastomosis in Wistar rats.
- The study adhered to the 3R principles and received animal welfare committee approval.
Main Results:
- Surgical times for most procedures decreased after the third attempt.
- Functional validity rates for aortic and vena cava anastomoses were 88.9% and 66.7%, respectively.
- Vena cava anastomosis times did not show significant improvement over 9 procedures.
Conclusions:
- The developed microsurgical training model is suitable for improving surgical time and functional outcomes.
- Standardized microsurgical training programs are essential for optimizing surgical education and results.
