Why do post-operative intra-abdominal adhesions form so commonly? what is the mechanism?

Peritoneal loss: Post-operative intestinal adhesions are due to the loss of the protective peritoneal membrane which envelops the small and large intestines.

Healing Process: Adhesions are fibrous bands of scar tissue that form after abdominal, pelvic, or thoracic surgery. They are part of the healing process and develop when the body’s repair mechanisms respond to any tissue disturbance.
