Results: The results from 191 patients who fulfilled the inclusion criteria, perforated appendicitis was found in 67 patients (35.1%). The factors associated with perforated appendicitis in elderly patients with statistical significance were BMI >25 kg/m2 (adjusted OR = 3.3, 95% CI; 1.4-7.8, p-value = 0.008), elevated temperature (adjusted OR = 5.6, 95% CI; 2.2-14.1, p-value = 0.003) and the duration from onset to admission increase every 1 hour (adjusted OR = 1.1, 95% CI; 1.1-1.1, p-value = 0.000).
