ABSTRACT
Abdominal and pelvic adhesions are a frequent occurrence and are responsible for significant
morbidity resulting in abdominal and pelvic pain, infertility, and small bowel obstruction.
The process of adhesion development begins when damage to peritoneal surfaces from
any source (operative trauma, infection, foreign bodies, desiccation, irradiation,
allergic reaction, or chemical injury) induces a series of biochemical/molecular biologic
cascades involving different elements. These elements include peritoneal fluid, neutrophils,
leukocytes, macrophages, cytokines, mesothelial cells, and tissue and coagulation
factors, which teleologically have the intention of peritoneal repair; however, these
processes also result in adhesion development. Major pathways that play significant
roles in the healing process of peritoneal damage leading to adhesion development
are the fibrinolytic system, extracellular matrix deposition, growth factor and cytokines,
cell adhesion molecules, angiogenesis, apoptosis and proliferation, and remesothelialization.
Greater understanding of the regulation and interaction of these processes provides
the potential for reduction of postoperative adhesion development.
