Editing Abdominal cavity (section)

===Inflammation===
Another disorder is called [[peritonitis]] which usually accompanies inflammatory processes elsewhere. It can be caused by damage to an organ, or from a contusion to the abdominal wall from the outside or by surgery. It may be brought in by the bloodstream or the [[lymphatic]] system. The most common origin is the [[gastrointestinal tract]]. Peritonitis can be [[acute (medicine)|acute]] or [[chronic (medicine)|chronic]], generalized or localized, and may have one origin or multiple origins. The [[omentum (disambiguation)|omenta]] can help control the spread of infection; however without treatment, the infection will spread throughout the cavity. An [[abscess]] may also form as a secondary reaction to an infection. [[Antibiotic]]s have become an important tool in fighting abscesses; however, external drainage is usually required also.<ref name=EB/>
