Pork Belly: A Simulation Training Model for Intramuscular Perforator Dissection.

摘要: Background Free tissue transfer has evolved from muscle flaps to fasciocutaneous flaps. Dissection of the intramuscular course feeding vessels is technically challenging. Simulation-based microsurgery skills acquisition moving toward nonliving training models. Living porcine model or human cadavers are currently cost-ineffective methods for early learning curve in teaching dissection. The aim this study was validate an inexpensive ex vivo simulating harvest deep inferior epigastric artery perforator (DIEAP) flap, specifically including Methods An initial needs analysis and anatomical dissections (characteristics vascular anatomy) established necessity surgical design (step-by-step) DIEAP flap harvesting model. A pilot utilizing objective assessment methodology (time complete raising hand motion analysis) demonstrated surgeons' performance. detailed feedback questionnaire used assess participants' perception Results Fifty-seven participants completed analysis. Fifteen pork bellies were dissected characteristics presented. Eight surgeons performed step-by-step demonstrating construct validity All they recommend as first step Conclusions belly simulation a cheap, easy, ethically considerate, high-fidelity dissection free flap. This guides future validation trials explore if absence physiological blood flow affects curve. could be perforators before progressing
