Abstract

Background and Objectives: Acute diverticulitis (AD) is the leading and most burdensome complication of colonic diverticulosis. However, risk factors for its development and predictors of its course are still poorly defined. In this regard, the association of a young age with a complicated course and worse outcome are still controversial. Moreover, little research has addressed the effect of ethnicity on the course of AD. The current study aimed to evaluate the impact of these variables on AD’s course and outcome in the diverse and unique ethnic landscape of Israel. Materials and Methods: We performed a retrospective review of the charts of patients with a radiologically confirmed diagnosis of AD. Patients’ outcomes and disease course, including hospitalization duration, complications, and recurrent episodes, were documented and compared among different age and ethnic groups. Multivariate analysis was performed to identify predictors of complicated AD. Results: Overall, 637 patients with AD were included, the majority (95%) had distal colon AD, and almost one quarter of them were aged less than 50 years. The majority of patients in the young age (<50) group were males (69.7%). Nonetheless, the rate of recurrent episodes (35.3% vs. 37.3%, p = 0.19), hospitalization duration (5 ± 4.7 vs. 6 ± 3.2, p = 0.09) and complications rate (17.3% vs. 13.7%; p = 0.16) were similar for both age groups. In the ethnicity group analysis, Arab minority patients had a first episode of AD at a significantly younger age compared to their Jewish counterparts (51.8 vs. 59.4 years, p < 0.001). However, factors such as a complicated course (16% vs. 15%; p = 0.08) and relapsing episode rates (33% vs. 38%; p = 0.36) did not differ significantly between groups. None of the variables, including young age and ethnic group, were predictors of complicated AD course in the multivariate analysis. Conclusion: AD is increasingly encountered in young patients, especially in ethnic minority groups, but neither ethnicity nor young age was associated with worse outcomes.
