Video-based microlearning improves vascular surgery resident proficiency in end-to-side anastomosis.

Objective: Effective and comprehensive surgical training poses a challenge for residency programs. Considering patient safety and limited work hours, training must be a time-efficient and effective use of simulation before practicing in the operating room. Therefore, we have integrated video-based microlearning for our surgical residents, focusing on end-to-side anastomosis techniques. By having three senior surgeons evaluate resident performance and give feedback to trainees, we aimed to validate the effectiveness of this educational approach. Methods: Surgical residents were initially instructed to perform end-to-side anastomosis using a Penrose (simulating an artery) and 6-0 Prolene with minimal input. Subsequently, they were asked to review an 11-step procedure document and 10 video-based microlearning modules for end-to-side anastomosis techniques before performing their next anastomosis. Three senior vascular surgeons assessed the residents' practical skills. They provided feedback and assigned scores out of 17 based on the 8-item procedural checklist, including bite spacing, eversion, heel-toe evaluation, total time, back-walling, posterior wall cut, and several possible leaks. Results: Trainee samples (n = 18 pairs) were continually graded and recorded. Feedback received from the participants highlighted the effectiveness of video-based microlearning. Paired Conclusions: Our study aimed to highlight the feasibility of video-based microlearning as a valuable adjunct to traditional vascular surgery residency training. As surgical training continues to evolve, such innovative learning approaches promise to optimize surgical education and ultimately improve patient outcomes in vascular surgery. Further research is warranted to explore the long-term impacts and scalability across residency programs.
