ABSTRACT
Peritoneal adhesion (PA) is a high morbidity complication after surgical procedures, with serious clinical consequences and requiring substantial medical expenditure. The pathogenesis of PA is complex and is still not very clear. Clinically, it is mainly treated by optimizing surgical protocols, using anti-adhesion drugs and biomaterial barriers. Although these methods have shown certain preventive effects, the effectiveness needs to be further improved. Elucidating the mechanism of PA formation is the basis and premise for preventing its occurrence. In the process of PA formation, a variety of inflammatory cells, inflammatory factors play important roles. In this paper, the mechanism of inflammation and immunoregulatory responses in the formation of adhesions in the peritoneal cavity was reviewed, in order to provide a reference for the improvement of PA prevention strategies.
