Adhesion (World Book Medical Encyclopedia).
"Adhesion is the growing together of body tissues that are normally separate. Adhesions (protective bands) form in some disorders, following injuries, or following surgery. The sticky healing fluid produced by the damaged internal tissue can solidify to form a band. This band then joins the injured tissue to any body structure or organ with which it comes in contact. Often this is a cavity wall, particularly in the abdomen. Usually this type of adhesion produces no problems. But if the structure so attached is normally free-moving, serious problems may result. The problem may require surgery. Abdominal adhesions of the bowel, for example, can produce pain and obstruction, which may demand surgical correction."
