Evaluation of tissue healing and adhesion formation after an intraabdominal amniotic membrane graft in the rat.
The amniotic membrane was used as a graft intraabdominally in the rat to study the healing process and the graft's efficacy in preventing postoperative adhesions. We observed the gradual invasion of the graft with fibroblasts and plasma cells and increased vascularity. By the tenth postoperative day the graft had taken completely. There was no evidence of infection at the graft site or rejection of the graft. Application of the graft after lysis of adhesions was followed by adhesion formation at the graft site. The graft did not show evidence of necrosis but failed to prevent adhesion formation.
