Clinical Analysis of Appendicitis in the Elderly Over 60 Years of Age

ABSTRACT

PURPOSE: As average life expectancies are prolonged, the elderly population is steadily increasing. The increasing number of elderly persons has been accompanied by cases of acute appendicitis in the elderly. In order to understand the clinical significance and to improve the treatment of elderly patients with appendicitis. we analyzed patients over 60 years of age with appendicitis. METHODS: We retrospectively reviewed the medical records of 268 patients over 60 years of age who were pathologically diagnosed with appendicitis. We analyzed the patients' clinicopathologic factors and outcomes, dividing them into 3 age groups 60~69, 70~79, 80 and over. RESULTS: Of the 268 patients, there were 109 male and 159 female. The sex ratio was 11.46. The numbers of patients in each group were 169 (63.1%) in the 60-69 group, 73 (27.2%) in the 70~79 group, and 26 (9.7%) in the over 80 group. There was no difference in the leukocyte count and the time delay in surgical treatment between the groups. In the older groups, compared to the younger groups, there were more frequent paramedian and median incisions in the operation (P=0.02), a longer duration of postoperative admission (P=0.001) and starvation after the operation (P<0.001). In the pathologic findings, the gangrenous and abscess stages of appendicitis were more frequent in the older groups than in the younger groups (P<0.001). CONCLUSIONS: Early aggressive diagnostic intervention, such as ultrasound and CT, is essential in managing appendicitis in elderly patients who complain of vague abdominal pain.
