Elderly patients with acute peritonitis may NOT present with typical symptoms of acute abdominal pain, fever, or leukocytosis due to an impaired immune response.

In elderly patients with acute appendicitis or acute cholecystitis, one-third lack symptoms of abdominal pain, one-third are afebrile, and one-third have a normal white blood cell count. Therefore an "unimpressive" abdominal examination is irrelevant in the evaluation of the elderly patient whose tolerance for food has suddenly changed.
