Ex vivo ovine model for pediatric flexible endoscopy training

Medical students and residents in training have limited opportunities to develop pediatric endoscopy skills and would benefit from a realistic simulation model. We sought to develop such a model for flexible endoscopy using fresh head and neck tissue from young sheep. Tissue was collected from pre-pubescent sheep (n = 5; mean age: 4 months; mean mass: 28 kg) following humane euthanasia at the end of an in vivo protocol. No live animals were used...
