title: Effect of dextran and hyaluronic acid on the development of postoperative peritoneal adhesions in experimental animals.
abstract: The development of postoperative peritoneal adhesions was studied in rats and rabbits, the frequency of adhesions in the experimental model used being very high. In the development of an adhesion, fibrin seems to be an important contributor to the bridge between different tissues. Dextran, which modifies the fibrin network and makes it more susceptible to lysis, was used as a possible prophylactic agent, but we found no difference between treated and control groups. It is concluded that the stimulus for fibrin formation in the peritoneal adhesions using this atraumatic model was too strong to be overcome by the normal fibrinolytic system. The anti-inflammatory reaction of hyaluronic acid did not diminish the frequency or degree of adhesions.
