Abstract:Objective To review the endoscopic examination data of patients with diverticulum of colon, and analyze the characteristics and correlation with the concurrent diseases.Methods The endoscopic data of patients from June 2014 to May 2019 were collected retrospectively. The detection rate of patients with diverticulum of colon and the correlation between colonic diverticulum and the associated diseases was analyzed by SPSS 19.0.Results The detection rate of colonic diverticulum was 2.78%. The detection rate of colonic diverticulum increased significantly from 1.79% at the first year to 3.35% at the fifth year. The detection rate of colonic diverticulum was positively correlated with colonic polyps, colon cancer, colonic lipoma, colonic mucosal melanosis and history of intestinal surgery (P < 0.05), but not with ischemic colitis (P > 0.05).Conclusion The detection rate of colonic diverticulum after 5 years was significantly increased. The detection rate of colonic diverticulum was significantly correlated with colonic polyps, colon cancer, colonic lipoma, colonic mucosal melanosis and abdominal surgery.
