PURPOSES: Factors other than antithrombotic drugs associated with diverticular bleeding remain unknown. Visceral adiposity contributes to atherosclerosis and may affect arteriolar change at the diverticulum. We investigated whether visceral adipose tissue (VAT) measured by computed tomography (CT) is a risk factor for diverticular bleeding.
METHODS: A cohort of 283 patients (184 with asymptomatic diverticulosis and 99 with diverticular bleeding) undergoing colonoscopy and CT was analyzed. Associations between body mass index (BMI), VAT, subcutaneous adipose tissue (SAT), and diverticular bleeding were assessed by logistic regression models adjusted for age, gender, alcohol, smoking, diabetes mellitus, hypertension, dyslipidemia, chronic kidney disease, and antithrombotic drugs (nonsteroidal anti-inflammatory drugs (NSAIDs), low-dose aspirin, and other antiplatelet drugs).
RESULTS: In univariate analysis, hypertension, dyslipidemia, chronic kidney disease, and NSAIDs use, low-dose aspirin, non-aspirin antiplatelets, increasing BMI, and increasing VAT area were associated with diverticular bleeding. In multivariate analysis adjusted for confounding factors, VAT area (p = 0.021), but not BMI (p = 0.551) or SAT area (p = 0.635), was positively associated with diverticular bleeding. When BMI was considered simultaneously, VAT area remained positively associated with diverticular bleeding (p = 0.018). However, none of obesity indices including VAT area were associated with recurrence of diverticular bleeding or prolonged hospitalization.
CONCLUSIONS: This study presents new information on risk factors for diverticular bleeding. A large volume of visceral adipose tissue, but not BMI or SAT, appears to entail a risk for diverticular bleeding, after age, gender, metabolic factors, and antithrombotic drugs use adjustments.
