Mortality rate of men vs women was similar in non-elderly group (1.9% vs 2%, respectively), whereas it significantly differed in elderly patients (4.5% vs 5.3%, respectively, P&lt;.0001). Time to operation was 1.15 (1.83) days in survived vs 1.55 (3.86)\u00a0days in deceased non-elderly patients ( P &lt; .001). Time to operation was .85 (1.73) days in survived vs 1.79 (7.28) days in deceased elderly patients ( P &lt; .001). In patients with operation, age, delayed operation, frailty, and presence of perforation were the main risk factors of mortality in both elderly and non-elderly patients. Invasive diagnostic procedure was shown as a protective factor in elderly patients. In the final model for patients with no operation, age, hospital length of stay, and frailty were the main risk factors of mortality in both elderly and non-elderly patients. Invasive diagnostic procedure was revealed as a protective factor in all patients as well.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n
