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.
住院医师工作时间规定以及微创外科技术的发展需要更有效和高效的外科技能教学模式。我们使用在腹壁成形术或腹部组织乳房重建术中获取的冻融人体组织残余物，以开展中型小组工作坊项目，模拟真实的手术环境以及视觉/触觉反馈。
全层腹部组织（皮肤和皮下脂肪）取自接受自体乳房重建且同意将其组织用于综合研究和医学教育目的的患者。匿名组织经冷冻保存，然后在手术技能工作坊当天解冻。共有53名住院医师在该工作坊项目的四场课程中以3至5人小组模块的形式完成了50分钟的实践培训。
解冻后的组织恢复了几乎正常的质地和稠度。组织学上也证实了结构完整性。所有参与者总体上对该项目感到满意，尤其是对所提供的缝合材料。
腹壁成形术或自体乳房重建术中的冻融组织残余物可以保存下来，并在保证匿名且获得适当同意的情况下，用作面向外科住院医师或医学生的中型小组工作坊中的缝合教育材料。这种方法提供了一个出色的模式，以最低成本维持相对真实的解剖结构和稠度。
