Complications of peritonitis include tertiary peritonitis, infection or dehiscence of the surgical site, enterocutaneous fistula, abdominal compartment syndrome, and enteric insufficiency. Enterocutaneous fistulae can lead to ongoing (potentially large) volume, protein, and electrolyte losses; inability to use the gut for nutritional support; and associated long-term complications of intravenous alimentation. Abdominal compartment syndrome is a well-recognized disease entity related to acutely increased abdominal pressure (ie, intra-abdominal hypertension) and is associated with the development of multiple organ dysfunction. Extensive initial (gastrointestinal) disease, chronic recurrent infections, and associated reoperations may lead to enteric insufficiency because of short gut, pancreatic insufficiency, or hepatic dysfunction.
