PURPOSE: Colonic diverticular bleeding is a major cause of lower gastrointestinal bleeding. However, a limited number of studies have been reported on the risk factors for diverticular bleeding. Our aim was to identify risk factors for diverticular bleeding.
METHODS: Our study design is a case (diverticular bleeding)-control (diverticulosis) study. We prospectively collected information of habits, comorbidities, history of medications and symptoms by a questionnaire, and diagnosed diverticular bleeding and diverticulosis by colonoscopy. Logistic regression models were used to estimate odds ratio (OR) and 95% confidence interval (CI).
RESULTS: A total of 254 patients (diverticular bleeding, 45; diverculosis, 209) were selected for analysis. Cluster (≥10 diverticula) type (OR, 4.0; 95% CI, 1.8-8.9), hypertension (OR, 2.2; 95% CI, 1.0-4.6), ischemic heart disease (OR, 2.4; 95% CI, 1.1-5.4), and chronic renal failure (OR, 6.4; 95% CI, 1.3-32) were independent risk factors for diverticular bleeding.
CONCLUSIONS: Large number of diverticula, hypertension, and concomitant arteriosclerotic diseases including ischemic heart disease and chronic renal failure are risk factors for diverticular bleeding. This study identifies new information on the risk factors for diverticular bleeding.
