Microsurgery Workout: A Novel Simulation Training Curriculum Based on Nonliving Models.

Area of Science:

• Microsurgery training
• Surgical education
• Animal models in surgery

Background:

• Current microsurgery training lacks programs solely based on nonliving models.
• Need for validated training to improve surgical skills.

Purpose of the Study:

• Develop and validate a microsurgery training program using nonliving models.
• Assess skill transfer from nonliving to live animal models.

Main Methods:

• Postgraduate residents underwent a 17-session training program using ex vivo chicken models for anastomosis.
• Objective structured assessment of technical skills (OSATS) and checklists were used for evaluation.
• Skill transfer assessed via live rat anastomosis, comparing results to experienced surgeons.

Main Results:

• Residents showed significant improvement in OSATS and checklist scores, indicating learning.
• Trainees were less efficient than experienced surgeons but achieved high patency rates in live rat models (100% artery, 50% vein).

Conclusions:

• A nonliving model-based microsurgery training program effectively imparts surgical skills.
• Acquired microsurgical skills are transferable to more complex live animal models.
