Abstract

aim: Approximately one in five patients with acute diverticulitis (AD) will experience a recurrence. This study aimed to investigate the factors at AD admission that correlate with recurrence and test the proposed risk of recurrence-score according to Sallinen et al. method: This retrospective study followed patients for five years who were admitted with operatively or computed tomography (CT)verified AD at Auckland City Hospital from January 2012–June 2013. Demographic, laboratory, radiological and patient-related factors at initial admission were analysed in relation to readmission with recurrent AD and to test a risk score presented by Sallinen et al. results: In the adjusted analyses, previous diagnosis of AD (OR, 7.3; 95% CI, 3.1–16.9), Māori ethnicity (OR, 5.7; 95% CI, 1.4–22.7) and complicated AD at index admission (OR, 2.5; 95% CI, 1.0–6.2), were all independent factors associated with readmission with recurrence. High-risk versus low-risk groups, according to the risk score, showed 71.4% and 18.6% recurrence rates, respectively. conclusion: History of diverticulitis and complicated AD are risk factors for recurrence. The finding of higher recurrence rate in Māori requires further investigation utilising appropriate research methodologies. The risk score presented by Sallinen et al. may be a useful predictor of recurrent AD.
