Objective:
: to evaluate the effectiveness of a collagen-based adhesive associated with fibrinogen and thrombin in experimental liver injury in rats.
Methods:
: the study included 30 Wistar rats randomly divided into three groups: A, B and C. All underwent standard liver traumatic injury. In group A the lesion was treated with the adhesive; in group B, with conventional absorbable suture; and in group C, there was 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 group treated with the adhesive showed the lowest hemostasis times (p = 0.0573, odds ratio 13.5) and lower incidence of adhesions (p = 0.0119). Microscopic histological alterations of Groups A and B were similar, with foreign body granuloma formation separating the adhesive material or the suture from the hepatic stroma.
Conclusion:
: the adhesive of collagen associated with fibrinogen and thrombin was effective in the treatment of experimental hepatic injury, providing a lower incidence of adhesions between the liver and surrounding structures.
Objetivo:
avaliar a eficácia de um adesivo à base de colágeno associado a fibrinogênio e trombina, no trauma hepático experimental em ratos.
MéTodos:
foram 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 estudo concluiu que o adesivo de colágeno associado a fibrinogênio e trombina foi eficaz no tratamento do trauma hepático experimental, proporcionado menor ocorrência de aderências entre o fígado e as estruturas vizinhas.
