Collagen, fibrinogen and thrombin biological addesive is effective in treating experimental liver injuriesObjective : 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.
