A population-based study of incidence, risk factors, clinical spectrum, and outcomes of ischemic colitis.

ABSTRACT:

Background & aims

Little is known about progression of ischemic colitis (IC) among unselected patients. We aimed to estimate the incidence, risk factors, and natural history of IC in a population-based cohort in Olmsted County, Minnesota.

Methods

We performed a retrospective population-based cohort and nested case-control study of IC. Each IC case was matched to 2 controls from the same population on the basis of sex, age, and closest registration number. Conditional logistic regression, the Kaplan-Meier method, and proportional hazards regression were used to assess comorbidities, estimate survival, and identify characteristics associated with survival, respectively.

Results

Four hundred forty-five county residents (median age, 71.6 years; 67% female) were diagnosed
