Long-term analysis of peritoneal plasminogen activator activity and adhesion formation after surgical trauma in the rat model

Recent literature has shown that a common pathway in postsurgical adhesion formation is a transient reduction in local plasminogen activator activity, shortly after peritoneal trauma. This deficit in fibrinolysis permits deposited fibrin to become organized into fibrous, permanent adhesions. Althoug...

description Recent literature has shown that a common pathway in postsurgical adhesion formation is a transient reduction in local plasminogen activator activity, shortly after peritoneal trauma. This deficit in fibrinolysis permits deposited fibrin to become organized into fibrous, permanent adhesions. Although adhesion formation is a process that continues beyond the first postoperative days, long-term analysis of this theory has not been performed. A standardized peritoneal adhesion model in the rat. Long-term analysis of the peritoneal fibrinolytic activity (extraction technique) was related to the extent of postsurgical adhesion formation, up to 1year postoperatively. Total and tissue plasminogen activator activity were significantly increased at days 3 and 8, and 1month postoperatively. A mean adhesion percentage of 75% per peritoneal defect was found to persist throughout all evaluation times, which was directly related to the increase of fibrinolysis. In contrast to the classical concept that adhesion formation is related to a reduction in fibrinolysis, an impressive increase of the fibrinolysis was found to be associated with the persistence of adhesions.
