Summary
A large population-based study has shown diabetes to be an independent risk factor for colon
cancer compared to the general population. Thus, the completion of an adequately prepped
colonoscopy is requisite in providing diabetics with adequate colon cancer screening.
Recent data has shown that diabetic patients have poorer response to bowel cleansing compared
to non-diabetics (with a standard PEG prep, only 62% of diabetic patients had their
colonoscopy preps rated as good or better vs. 97% of normal patients, p<0.001). This may be
due to the fact that a majority of diabetic patients report constipation as a common
gastrointestinal complaint.
We postulate that lubiprostone (Amitiza), in combination with PEG, will have additional
efficacy over standard PEG preparation, and provide optimal safe and effective colonic
cleansing for diabetics.
