Residents' duty-hour regulations and the evolution of minimally invasive surgical techniques require more effective and efficient surgical skill teaching models. We used frozen-thawed human tissue remnants harvested during abdominoplasty or abdominal tissue-based breast reconstruction to allow for a medium-sized group workshop program, simulating a realistic surgical environment and visual/haptic feedback.


Full-thickness abdominal tissue (skin and subcutaneous fat) were donated from patients who underwent autologous breast reconstruction and gave consent to use their tissue for comprehensive research and medical educational purposes. Anonymized tissue was frozen-preserved and then thawed the day of the surgical skills workshop. A total of 53 residents completed 50-minute hands-on training in 3-to-5 person modules in four sessions of the workshop program.


Thawed tissue regained almost normal texture and consistency. Structural integrity was also histologically confirmed. All participants were generally satisfied with the program, especially regarding the suture material provided.


Frozen-thawed tissue remnants from abdominoplasty or autologous breast reconstruction could be preserved and used as a suture education material in medium-group workshops for surgery residents or medical students given anonymity and with proper consent guaranteed. This approach provided an excellent model maintaining relatively real anatomic structure and consistency with minimal cost.
