Adhesions are fibrous bands of scarlike tissue that form between two surfaces inside the body.

Alternative Names

Pelvic adhesion; Intraperitoneal adhesion; Intrauterine adhesion

Causes, incidence, and risk factors

Inflammation, surgery, or trauma can cause tissues to bond to other tissue or organs (much like the process of forming scar tissue). Sometimes, fibrous bands (adhesions) can be formed between the two surfaces. Abdominal surgery, congenital bands, or attacks of appendicitis or pelvic inflammatory disease can also cause intraperitoneal adhesions. Depending on the tissues involved, adhesions can cause various disorders. In the eye, adhesion of the iris to the lens can lead to glaucoma . In the intestines, adhesions can cause partial or complete bowel obstruction . Intrauterine adhesions occur often enough that they have a name of their own -- Asherman syndrome. Pelvic adhesions can lead to infertility and reproductive problems.

Signs and tests

Physical examination varies depending on the location of the adhesion. Various tests, such as a laparoscopy for suspected pelvic adhesions, hysteroscopy, or hysterosalpingography, may be recommended.


Surgery may be performed to separate the adhesions. This is often sufficient to allow normal movement of the organ and to reduce the symptoms caused by the adhesion. However, the risk for more adhesion increases as the number of surgery increases.

Expectations (prognosis)

The outcome is usually favorable.


Glaucoma , infertility , and bowel obstruction are possible complications of adhesions.
