title: Experience report on teaching surgical technique without animal use.
abstract: OBJECTIVE
  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.
  
  
  CONCLUSIONS
  The experimental models presented are easily reproducible and of low cost.
