Abstract
ObjectiveDiverticulosis is extremely common in western society. A recent study has shown that outpatient, nonantibiotic management of acute uncomplicated diverticulitis may be a feasible and safe option. However, the ability to identify these patients is still difficult. This study explores the ability of white cell count, C-reactive protein, and bilirubin in differentiating patients with complicated and uncomplicated diverticulitis, as well as progression to surgical intervention.MethodsThis is a retrospective study of patients admitted with acute diverticulitis over a 5-year period (2009–2014) at a single institution in Australia. Patients were classified into 3 groups; uncomplicated diverticulitis, complicated diverticulitis without surgery, and complicated diverticulitis with surgery. Analysis of variance (ANOVA) and Bonferroni's post hoc analyses were used to compare markers across the groups.ResultsA total of 541 patients met the inclusion criteria for this study. One-way ANOVA showed a significant difference in white cell count (P < 0.0001), C-reactive protein (P < 0.0001), and bilirubin (P = 0.0006) between all 3 groups. Post hoc analyses showed a significant difference in white cell count, C-reactive protein, and bilirubin when comparing uncomplicated diverticulitis against complicated diverticulitis without surgery (P < 0.05) and complicated diverticulitis with surgery (P < 0.05). White cell count also showed a significant difference when comparing complicated diverticulitis without surgery and complicated diverticulitis with surgery (P < 0.05).ConclusionsWhite cell count, C-reactive protein, and bilirubin can distinguish between uncomplicated and complicated diverticulitis.
