Fibrin sealant in high-risk colonic anastomoses

Abstract

The use of fibrin sealant has been advocated to enhance the healing of high-risk intestinal anastomoses. Colonic anastomoses were performed in 162 rats randomly assigned to four groups: control animals with or without fibrin sealant applied to the anastomosis and steroid-treated animals with or without fibrin sealant. At five days postoperatively, the use of steroids alone significantly reduced the anastomotic bursting pressure (ABP) and enhanced abscess and adhesion formation. The addition of fibrin sealant to the anastomosis in steroid-treated animals did not improve ABP and, in fact, further increased abscess formation. In control animals, the use of fibrin sealant also reduced ABP and enhanced abscess and adhesion formation. By ten days, there was no difference in ABP among the groups, and the rate of abscess formation was reduced in all groups. These findings indicated that short-term treatment with steroids delayed colonic anastomotic healing. Fibrin sealant did not enhance the integrity of these high-risk anastomoses. The present data do not support the use of fibrin sealant in high-risk colonic anastomoses.
