Síntese da parede abdominal: avaliação de dois tipos de sutura contínua em ratos
PURPOSE: To establish morphologic relationship between the continuous simple mass suture and the continuous far-near, near-far mass suture of longitudinal midline abdominal incision. METHODS: A total of 48 male Wistar rats underwent longitudinal standard laparotomy with equal distribution to one of...

| Sumario: | PURPOSE: To establish morphologic relationship between the continuous simple mass suture and the continuous far-near, near-far mass suture of longitudinal midline abdominal incision. METHODS: A total of 48 male Wistar rats underwent longitudinal standard laparotomy with equal distribution to one of two groups: GI- continuous simple mass suture, GII-continuous far-near, near-far suture, both with polypropylene. On postoperative day 7th or14th, 12 animals of each group were submitted to euthanasia and anterior abdominal wall was removed (without skin) for histologic and immune- histochemistry analysis. The samples of the abdominal wall were stained by hematoxylin-eosin in order to performed a qualitative healing tissue reaction. Others samples were stained by Picrosirius red F3BA in order to performed a quantitative analysis of macrophages and collagen. Statistical analysis was done by use the chi-square test, Fisher exact test and Mann-Whitney variance test ( p< 0,05). RESULTS: The findings of the macrophages cells and the collagen evaluation were statistical significantly on day 7th. CONCLUSION:The continuous far-near, near-far technique improved the abdominal wall healing on day 7th. On day 14th the findings were the same. |
