[Epidemiological investigation of colonic diverticulosis detected by computed tomography colonography].

Among 586 patients who underwent computed tomography colonography (CTC) from May 2012 to September 2017, 333 were diagnosed with colonic diverticulosis. The incidence of colonic diverticulosis increases with age. Despite a high frequency of ascending colonic diverticulosis, multiple diverticulosis (>10 in a colonic segment) were the most frequent in the sigmoid colon. In previous studies, the frequency of detection of colonic diverticulosis by CTC was higher than that by colonoscopy and barium enema. In addition, using CTC, the detection rate of colonic diverticulosis has been recently increasing, suggesting that CTC is the most sensitive procedure for detecting colonic diverticulosis.
