RESUMO
Presentation of 55 patients aged more than 65 years, appendectomized with the diagnosis of acute appendicitis. After histological study, we saw 6 normal cecal appendixes (10.9%), so the real number of acute appendicitis operated was 49 out of 435 (11.2%) interventions. The clinical history was typical in most of the patients and, nevertheless, we noticed a diagnostic delay greater than 24 hours in 31 (63.2%), and greater than 48 hours in 17 patients (34.6%). We verified the existence of a high percentage of perforated appendicitis (36.7%) closely related to a long evolution time, not being able to show, in the group studied, an increase of early appendix perforations in comparison with the rest. These results suggest that the high morbidity of acute appendicitis in old patients is due, to a great extent, to a delay in the performance of the appendectomy.
