Prevalence and Natural History of Segmental Colitis Associated With Diverticulosis

INTRODUCTION: We assessed the prevalence and clinical outcomes of segmental colitis associated with diverticulosis (SCAD) in patients with newly diagnosed diverticulosis.METHODS: A 3-year international, multicenter, prospective cohort study was conducted involving 2,215 patients.RESULTS: SCAD diagnosis was posed in 44 patients (30 male patients; median age: 64.5 years; prevalence of 1.99%, 95% confidence interval, 1.45%-2.66%). Patients with SCAD types D and B showed worse symptoms, higher fecal calprotectin values, needed more steroids, and reached less likely complete remission.DISCUSSION: Although SCAD generally had a benign outcome, types B and D were associated with more severe symptoms and worse clinical course.[GRAPHICS].
