Abstract: | ObjectiveTo evaluate the influence of age on the evolution and severity of peritonitis.DesignA chart review.SettingAn adult university hospital.PatientsOne hundred and twenty-two patients with acute appendicitis and 100 patients with acute colonic diverticulitis requiring operation or percutaneous drainage.Main Outcome MeasuresPatient age and sex, presence of perforation or gangrene (appendicitis), extent of peritonitis (diverticulitis); duration of symptoms prior to admission; admission leukocyte count; duration of hospitalization before surgery; length of hospital stay; and death rate.ResultsPatients with acute appendicitis who were aged 65 years or older were three times more likely than younger patients to have a gangrenous or perforated appendix (odds ratio 3.1, 95% confidence interval 1.1 to 8.4, p < 0.05); older patients with perforated diverticulitis were three times more likely than younger patients to have generalized peritonitis than localized (pericolic or pelvic) peritonitis (odds ratio 2.9, 95% confidence interval 1.2 to 7.5, p < 0.05).ConclusionThese findings are consistent with the hypothesis that the biologic features of peritonitis differ in the elderly, who are more likely to present with an advanced or severe process than young patients. |
