Acute diverticulitis: Demographic, clinical and laboratory features associated with computed tomography findings in 741 patients

Abstract

Background: Computed tomography (CT) demonstrates diverticulitis severity. Aim: To assess demographic, clinical and leucocyte features in association with severity. Methods We reviewed medical records of 741 emergency department cases and in-patients with diverticulitis. CT findings were: (i) nondiagnostic; (ii) moderate (peri-colic inflammation); and (iii) severe (abscess and/or extra-luminal gas and/or contrast). Results: Patients with severe vs. nondiagnostic/moderate findings had fewer females (42.4% vs. 58.2%, P = .004), less lower abdominal pain only (74.7% vs. 83.7%, P = .042) and more constipation (24.4% vs. 12.5%, P = .002), fever (52.2% vs. 27.0%, P < .0001), leucocytosis (81.5% vs. 55.2%, P < .0001), neutrophilia (86.2% vs. 59.0%, P < .0001), 'bandemia' (18.5% vs. 5.5%, P < .0001) and the triad of abdominal pain, fever and leucocytosis (46.7% vs. 19.9%, P
