Peritoneal regeneration and pathogenesis of postoperative peritoneal adhesions formation
Journal Title: Хірургія України - Year 2019, Vol 0, Issue 3
Abstract
Despite the long history of the peritoneal regeneration and the peritoneal adhesions formation pathogenesis studies, as well as a large number of clinical and experimental trials, so far, many questions about the pathophysiology of postoperative adhesions remain controversial. Postoperative formation of peritoneal adhesions is considered to be part of a pathological regeneration process that occurs after any peritoneum injury, especially in connection with surgery. Factors that lead to formation of adhesions are different (mechanical, physical, chemical, infectious, implantation). Inflammatory mediators, free radical oxidation processes, and oxidative stress also play an important role in the modulation of adhesions. A key role in the formation of adhesions belongs to pathological decrease in peritoneal fibrinolytic activity in response to inflammation and surgery. Studies on both animal models and humans have shown that two major factors lead to a decrease in fibrinolysis: a decrease in local tPA activity and an increase in PAI‑1 activity locally and systemically. It is the balance between the activity of tPA and PAI‑1 that plays a central role in the pathological adhesion formation, and the imbalance correlates with the severity of the adhesive process. Thus, pathological adhesion is a multifactorial condition, the development of which is due to a combination of various factors, many of which are genetically determined by local and systemic reactions of the body, and features of surgical treatment. To develop effective methods for prevention and treatment of adhesions, a more complete understanding of this process is needed at both the cellular and molecular genetic levels. The key to preventing post‑operative adhesion formation is likely to be the selective suppression of one or more critical factors that are necessary for its formation. There are practically no works in literature to study the features of adhesions pathogenesis in children.
