Impact of type 2 diabetes on adenoma detection in screening colonoscopies performed in disparate populations.

Background: The Black/African Ancestry (AA) population has a higher prevalence of type 2 diabetes mellitus (T2DM) and a higher incidence and mortality rate for colorectal cancer (CRC) than all other races in the United States. T2DM has been shown to increase adenoma risk in predominantly white/European ancestry (EA) populations, but the effect of T2DM on adenoma risk in Black/AA individuals is less clear. We hypothesize that T2DM has a significant effect on adenoma risk in a predominantly Black/AA population.

Type 2 diabetes impacts colorectal adenoma detection in screening colonoscopy.

Background: Diabetes is associated with an increased risk of colorectal cancer (CRC). We conducted a retrospective analysis of adenoma detection rates (ADR) in initial screening colonoscopies to further investigate the role of diabetes in adenoma detection.

Methods: A chart review was performed on initial average risk screening colonoscopies (ages 45-75) during 2012-2015.
