Association between colonic polyps and diverticular disease.
OBJECTIVE
To evaluate the association between colonic polyps and diverticular disease in Japan.


METHODS
We retrospectively reviewed the medical records of 672 consecutive patients who underwent total colonoscopy between August 2006 and April 2007 at Nishinjo Hospital, Okinawa, Japan. Patients with a history of any of the following were excluded from the study: previous polypectomy, colonic resection, and inflammatory bowel diseases. The association between colonic polyps and diverticular disease was analyzed by logistic regression analysis, adjusted for age and sex.


RESULTS
Prevalence of colonic polyps in all patients with diverticular disease was significantly higher than that in those without diverticular disease (adjusted odds ratio 1.7).


CONCLUSIONS
Our data showed that patients with diverticular disease have a higher risk of colonic polyps compared to those without.
