Acute diverticulitis in younger patients: Any rationale for a different approach?

AIM: To compare the natural history and course of acute diverticulitis in a younger age group with an older population and to evaluate whether younger patients should be managed differently. METHODS: This study was a retrospective review of 157 patients treated with acute diverticulitis between January 1, 2004 and December 31, 2007. Diverticulitis was stratified according to the Hinchey classification. Patients were divided into 2 populations: group A <= 50 years (n = 31); group B > 50 years (n = 126). Mean patient follow-up was 15 mo. RESULTS: The median age was 60 years. A significantly higher proportion of patients in group B presented with complicated diverticulitis (36.5% vs 12.9%, P = 0.01). Recurrence was more frequent in group A (25.8% vs 11.1%, P = 0.03) and the mean time-to-recurrence was shorter (12 mo vs 28 mo, P = 0.26). The most severe recurrent episodes of acute diverticulitis were classified as Hinchey stage I and none of the patients required emergency surgery. In multivariate analysis, only age (P = 0.024) was identified as an independent prognostic factor for recurrence. CONCLUSION: Based on the results of this study, we recommend that diverticulitis management should be based on the severity of the disease and not on the age of the patient. (C) 2011 Baishideng.
