title: Surgical model pig ex vivo for venous dissection teaching in medical schools.
abstract: OBJECTIVE
  To investigate a method for development of surgical skills in medical students simulating venous dissection in surgical ex vivo pig model.
  
  
  METHODS
  Prospective, analytical, experimental, controlled study with four stages: selection, theoretical teaching, training and assessment. Sample of 312 students was divided into two groups: Group A - 2nd semester students; Group B - students of 8th semester. The groups were divided into five groups of 12 students, trained two hours per week in the semester. They set up four models to three students in each skill station assisted by a monitor. Teaching protocol emergency procedures training were applied to venous dissection, test goal-discursive and OSATS scale.
  
  
  RESULTS
  The pre-test confirmed that the methodology has not been previously applied to the students. The averages obtained in the theoretical evaluation reached satisfactory parameters in both groups. The results of applying OSATS scale showed the best performance in group A compared to group B, however, both groups had satisfactory medium.
  
  
  CONCLUSIONS
  The method was enough to raise a satisfactory level of skill both groups in venous dissection running on surgical swine ex vivo models.
