• Resumo:

  PURPOSE: To evaluate if latex coated polypropylene mesh leads to less adhesions formation. METHODS: 90 rats were distributed in three groups. Group I (control) was submitted to median laparotomy and posterior synthesis; Group II (polypropylene) was submitted to a segment resection of the abdominal wall, and the defect was corrected with a polypropylene mesh; Group III using the new material (latex coated polypropylene). After 45 days the euthanasia procedure was done and the adhesions were evaluated in 2 ways: 1) classification in a grading system; 2) evaluation of the adhesion area, which was calculated by resection of the adhesions after dying with Indian blue ink. RESULTS: The classification in a grading system showed that Group III animals had less adhesions formation (P<0.05), but the evaluation of the adhesion area did not show any difference (P>0.05). The severe complications (fistula, evisceration and obstruction), which were lethal, were not reduced by the latex coated material. CONCLUSION: Latex coated polypropylene causes fewer adhesion formations than polypropylene alone, although it does not diminish the severe early complications.
