Adhesion barrier
An adhesion barrier is a medical implant that can be used to reduce abnormal internal scarring (adhesions) following surgery by separating the internal tissues and organs while they heal.
Surgeons have realized that proper surgical technique is crucial to reduce adhesion formation. In addition, for more than a century, adjuvants including drugs and materials such as animal membranes, gold foil, mineral oil, sheets made of rubber and Teflon, have been used to reduce the risk of adhesion formation. Nevertheless, adhesions do occur and appear to be, to some degree, an almost unavoidable consequence of abdominal and pelvic surgery. Adhesions can lead to significant post-surgical morbidity, bowel obstruction, infertility, and chronic pelvic pain or chronic abdominal pain.
Surgeons and healthcare professionals developed several methods for minimizing tissue injury in order to minimize the formation of adhesions. However, even an experienced surgeon despite using advanced techniques may not be able to fully prevent the formation of adhesions following surgery, without the aid of an adhesion barrier. Consequently, many surgeons apply adhesion barriers while performing abdominal and pelvic surgery.
==Description==
Adhesion barriers are physical films, fabrics, gels or other materials that are applied between layers of tissues at the end of a surgery before the incision site is closed. While in place, the adhesion barrier acts as a physical barrier to separate traumatized tissue surfaces so that they do not adhere to one another while the tissue surfaces heal. Once the tissue surfaces heal, which is usually between 3 and 7 days, the barrier dissolves and is absorbed by the body.
