Objective:
to evaluate the effectiveness of an collagen-based adhesive associated with fibrinogen and thrombin in experimental liver injuries in rats.
Methods:
we randomly divided 30 Wistar rats into three groups: A, B and C. All underwent a standard liver traumatic injury. In group A, the lesion was treated with the adhesive; in group B, with conventional, absorbable suture; group C received no treatment. We analyzed the time of hemostasis, mortality, occurrence of adhesions and any histological changes.
Results:
there was no statistical difference in relation to mortality (p=0.5820). The adhesive treated group showed the lowest hemostasis times (p=0.0573, odds ratio 13.5) and lower incidence of adhesions (p=0.0119). The histological alterations of the Groups A and B were similar, with foreign body granuloma formation separating the adhesive material and the hepatic stroma suture.
Conclusion:
the collagen adhesive associated with fibrinogen and thrombin was effective in treating experimental hepatic injury, providing a lower incidence of adhesions between the liver and surrounding structures.
Objetivo:
avaliar a eficácia de um adesivo a base de colágeno associado ao fibrinogênio e trombina, no trauma hepático experimental em ratos.
MéTodos:
toram incluídos no estudo 30 ratos Wistar, igualmente divididos aleatoriamente em três grupos: A, B e C. Todos foram submetidos à lesão traumática hepática padronizada. No grupo A, a lesão foi tratada com o adesivo, no grupo B, com sutura convencional com fio absorvível, e no grupo C, não houve tratamento da lesão. Foram analisados o tempo de hemostasia, mortalidade, ocorrência de aderências e eventuais alterações histológicas.
Resultados:
os resultados mostraram que não houve diferença estatística em relação à mortalidade (p=0,5820). O grupo tratado com adesivo apresentou os menores tempos de hemostasia (p=0,0573 e odds ratio 13,5) e menor ocorrência de aderências (p=0,0119). Microscopicamente as alterações histológicas dos grupos A e B foram semelhantes, com a formação de granuloma de corpo estranho separando o material do adesivo e do fio de sutura do estroma hepático.
ConclusãO:
o adesivo de colágeno associado ao fibrinogênio e trombina foi eficaz no tratamento do trauma hepático experimental, proporcionado menor ocorrência de aderências entre o fígado e as estruturas vizinhas.
