Budzynska K, et al. - In this retrospective cohort study, researchers investigated whether increased risk of colorectal adenomatous polyps is linked with diabetes mellitus (DM), its treatment, or hemoglobin A1c (HbA1c) level. They examined the details of colonoscopy and pathology findings and confirmed the diagnosis of DM by performing chart review for 1,800 randomly selected patients who had at least one colonoscopy. The known increased risk of adenomatous polyps with advancing age, male gender, Hispanic race/ethnicity and higher body mass index was corroborated by the findings. A link between DM and adenomatous polyps was suggested, but after controlling for other potential confounders, no statistically significant association was observed.
