title: [Clinical research X. Usefulness of an organic mesh in the repair of abdominal defects].
abstract: OBJECTIVE
  to measure the compliance, security and usefulness of organic mesh (bovine pericardium) in the repair of abdominal defect in an animal model.
  
  
  METHODS
  Wistar rats (weight 300 to 500 g), were anesthetized and an abdominal defect of 1 cm in each animal was performed. Animals were divided according to the repair material used: bovine pericardium mesh (n = 6) and polipropilene mesh (n = 6). Animals were sacrificed on day 28 after the surgery. Presence of infection, necrosis and adherences (macroscopic and microscopic) were compared. Tensile force was also measured in both groups.
  
  
  RESULTS
  inflammation, necrosis and adherences were similar in both groups. The prolene mesh (mean rupture force 66.5 joules) was stronger than bovine pericardium (mean rupture force 47.4 joules) p = 0.002, however, had also more adherences.
  
  
  CONCLUSIONS
  there is no difference between inflammation, necrosis and adherences. But the polipropilene mesh was stronger than the bovine pericardium mesh. This finding could have relevance in the clinical practice (hernia recurrence).
