Abstract

Objective To explore the age and gender differences in CT signs of acute appendicitis at different disease courses. Methods 235 patients with acute appendicitis treated in our hospital from June 1, 2021 to June 30, 2024 were included as study objects, which were divided into simple group （acute simple appendicitis, n=32）, suppurative group （acute suppurative appendicitis, n=185） and gangrene group （acute gangrenous appendicitis, n=18）, respectively. The imaging findings of patients at different disease courses of different age and gender were compared by multi-slice spiral CT plain scan. Results The age and the time from onset to treatment in pyogenic group and gangrene group were higher than that in simple group （P<0.05）. The incidence of appendiceal thickening and peri appendiceal exudation in pyogenic group was higher than that in simple group （P<0.05）, and the proportion of alcohol consumption in gangrene group was higher than that in simple group （P<0.05）. Among the disease courses <24 h and 24~48 h, the incidence of endovascular gas in the ≥65 years old group were lower than that in the 45~64 years old group （P<0.05）, while there were no statistically significant differences in the other comparisons （P>0.05）. There was no statistically significant difference in CT signs among patients with different disease courses and genders （P>0.05）. Gender was a predictor of appendiceal thickening, and disease course was a predictor of peri appendiceal exudation, extraluminal free gas （P<0.05）. Conclusion Age was closely related to the severity of acute appendicitis and the signs of endovascular gas, while gender had a predictive effect on the appendiceal thickening, and the disease course had a predictive effect on peri appendiceal exudation, extraluminal free gas.
