Experience report on teaching surgical technique without animal use

PURPOSE: To report the experience of the school in implementing the 3 Rs replace, reduce and refine; showing time and assembling cost of the experimental models used in the teaching of Surgical Technique and Experimental Surgery.METHODS: Assembly time and costs of models: grafts and flaps performed in pork belly, model of intestinal anastomosis and jejunostomy done in Bahiana box and black box model for training videosurgery.RESULTS: Average time and cost estimate: ten minutes-pork belly, cost $ 6.00 per kilogram; two minutes-Bahiana box, cost $ 27.2; Black box-3.6 hours for manufacturing, cost $ 100.00. The repetition of each practice the cost is $ 3.20 for Bahiana box and at no cost to the black box.CONCLUSION:The experimental models presented are easily reproducible and of low cost.(AU)

New experimental model for training in videosurgery / Novo modelo experimental para treinamento em videocirurgia

PURPOSE: To develop a new experimental model of lower cost for training in videosurgery. METHODS: This project was performed at the Nucleus of Experimental Surgery of the Bahiana School of Medicine and Public Health, based on previous models described in the literature and under the supervision of the full professor of Operative Technique and Experimental Surgery II. It was made a model cube-shaped, made of wood, with holes distributed in various locations, rubber stoppers for the holes and lined externally with carpet, and internally with laminate. RESULTS: The new experimental model is of low cost and reproduces quite faithfully several videosurgical procedures. CONCLUSION: Medical schools interested in the subject may adopt the new model for training in videosurgery without the need of high costs for making and using these models.(AU)

OBJETIVO: Desenvolver um novo modelo experimental de baixo custo para treinamento em videocirurgia MÉTODOS: Este projeto foi conduzido no Núcleo de Cirurgia Experimental da Escola Bahiana de Medicina e Saúde Pública, baseado em modelos prévios descritos na literatura e sob a supervisão do professor titular de Técnica Operatória e Cirurgia Experimental II. Foi feito um modelo em formato de cubo, de madeira, com furos distribuídos em vários locais, tampas de borracha para os orifícios e forrado externamente com carpete e internamente com laminado. RESULTADOS: O novo modelo experimental desenvolvido é de baixo custo e reproduz de forma bastante fiel diversos procedimentos videocirúrgicos. CONCLUSÃO: Faculdades médicas interessadas no tema poderão adotar o novo modelo para o treinamento em videocirurgia sem que sejam necessários gastos elevados para a confecção e o uso desses modelos.(AU)
