Differences in the Clinical Course of Acute Appendicitis in Geriatric Patient Groups

Objective: To compare the differences in the clinical course of acute appendicitis between early elderly (60-79 years) and late elderly patients (≥80 years). Method: The sample consisted of 177 patients aged over 60 that underwent surgery at the emergency service with the diagnosis of acute appendicitis between January 2010 and May 2018. Patients’ data were retrospectively obtained from electronic records. Patients that had undergone appendectomy or negative appendectomy or had an appendix tumor were excluded from the study. The patients were divided into two groups by age; early elderly (60-79 years) and late elderly (≥80 years). Results: Of the 177 patients included in the study, 162(91%) were 60-79 years old and 15 (9%) were over 80. A statistically significant difference was found between the early and late elderly groups in terms of perforation, requirement for intensive care (p =0.001), red cell distribution width (p =0.025), the Clavien-Dindo classification (p =0.020), and the Charlson comorbidity index (p =0.005). The mean hospital stay was four and 11 days for early and late elderly groups, respectively. Multivariate analysis revealed that age alone was an independent factor with a statistically significant effect on mortality (OR=Odds Ratio: 53, 95% CI: 16.91-166.08; (p <0.001)). Conclusion: In particular, in the elderly patients over 80 years old, the clinical manifestation of acute appendicitis at hospital admission is in the form of perforation. Therefore, in this age group, a careful, precise and prompt diagnosis is crucial.
