Association Between Diverticulosis and Colonic Neoplasia: A Meta-Analysis
To the Editor: We were interested in the article written by Peery et al (1). The authors performed a study in patients who underwent screening colonoscopy to assess the association between colonic diverticula and colonic adenomas. They found that diverticula were not associated with an increased risk of either adenomas or advanced adenomas. Several studies assessing these associations reported conflicting results. Thus, we conducted a meta-analysis to determine the strength of association between colonic diverticula and colonic neoplasms.
