Summary
Brief summary (as posted)
This study seeks to justify performing an incidental appendectomy according to the following hypotheses: 1. The frequency of neoplasms in pathohistological (PHD) findings of incidental appendectomy (IA) is significantly higher than in PHD findings in appendectomies for acute appendcitis (AA) 2. The number needed to treat (NNT) for appendiceal tumors in the elderly is less than 500. 3. The rate of complicated AA in the elderly population is significantly higher than in the younger age group 4. NNT IA for complicated appendicitis in the elderly is less than 300. 5. NNT IA for potential death due to AA in the elderly is less than 500.

Inclusion Criteria: Adult patients operated for colon tumors who have data on age, sex, data on a previously diagnosed colon tumor, data on incidental appendectomy, and a PHD finding for a removed appendix. Adult patients who have been diagnosed with acute appendicitis and have data on age, sex, data on the diagnosis of acute appendicitis and accompanying PHD findings, newly performed appendectomies. Exclusion Criteria: We will exclude from the analysis patients who had previous appendectomy, appendectomy has not been performed or we do not have an accompanying PHD finding of the appendix, and patients younger than 18 years.
