[] What are adhesions and why are they a problem?

Adhesions are fibrous bands connecting structures that are normally separate. They develop as normal tissue responds to some form of injury. Adhesions can lead to a variety of complications, which include pelvic pain, infertility and bowel obstruction.

Why do adhesions form?

Some of the causes of adhesion formation are:

Trauma -- Trauma is frequently a major contributor to the formation of adhesions. It has been shown that adhesions that form after surgery are a result of the body’s normal healing process.

Ischemia -- During surgery, blood flow often must be disrupted by cutting, coagulation or tying of sutures. This disruption can result in ischemia, or lack of blood supply. This can also lead to inflammation and cause adhesions to form.

Foreign bodies -- Foreign bodies can also cause an inflammatory reaction in the body. A foreign body can be suture material, lint from sponges, or talc from surgical gloves. Local cells respond to the foreign body by releasing factors that incite an inflammatory reaction which may result in adhesions.

Hemorrhage -- Hemorrhage brings blood products into the operating field. The raw surfaces from the operation plus the blood from tissues can enhance the formation of adhesions.

Infection -- Infection from a variety of sources, endometriosis or pelvic inflammatory disease can cause inflammation, which can result in adhesion formation.

[] Where do adhesions form?

Adhesions are common and can form on any surface in the pelvis and abdomen after surgery. Some organs, though, are more likely than others to develop adhesions. The ovary, pelvic sidewall and fimbria are the most common sites for adhesion formation. A study found that adhesions formed 55% of the time following surgery to the ovary, 40% of the time following surgery to the pelvic sidewall, and 36% of the time following surgery to the fimbria.
