Abstract

Background/Aims
Colonic diverticular diseases are increasing in Korea due to aging of the population and westernization of people's lifestyle. The aim of this study was to investigate the clinical predictors associated with the severity of colonic diverticulitis in Korea. Methods: We retrospectively reviewed the medical records of 107 patients who were hospitalized with diverticulitis and underwent abdominopelvic computerized tomography at Dankook University Hospital between March 2002 and August 2011. The severity of colonic diverticulitis was evaluated by using Modified Hinchey classification, stage 0 to stage Ia were classified as mild group and stage Ib to stage IV were classified as severe group. Patients' records were assessed for age, sex, underlying diseases, history of diverticulitis, associated symptoms, location of diverticulitis, white blood cells, and C-reactive protein (CRP). Results: Male to female ratio was 1.6:1 with the mean age of 43.1 years. Eighty-three patients (77.6%) were in the mild group and 24 patients (22.4%) were in the severe group. In multivariated analysis, the clinical predictors associated with the severity of colonic diverticulitis were left location (odds ratio [OR], 7.268; P=0.030), duration of symptoms (≥3 days; OR, 4.174; P=0.022), and elevated CRP (≥5 mg/dL; OR, 4.576; P=0.018). Conclusions: Left location, duration of symptom, and elevated CRP were the meaningful predictors for severity of colonic diverticulitis. When confronting with patients with these risk factors, we should keep in mind about the possibility of severe diverticulitis. (Intest Res 2013;11:23-27)
