title: High prevalence of hyperplastic colonic polyps in acromegalic subjects.
abstract: We evaluated the prevalence and features of colonic polyps in a population of acromegalic subjects, compared to a control group of patients with irritable bowel syndrome (IBS). Colonic polyps were found in 30 acromegalic subjects (40%) and in 10 controls (13%) (P < 0.0001). Among the acromegalic patients, polyps were of the hyperplastic type in 27 subjects (90%) and adenomatous in 3 (10%). In the control group, polyps were hyperplastic in nine subjects (90%) and adenomatous in one (10%). We also observed a significant association (P < 0.0001) between the presence of hyperplastic polyps and the older age in both the acromegalic and the control groups. There were no differences between the two groups regarding sex, site, size, or macroscopic and histological types of polyps. Acromegalic patients have a higher prevalence of colonic hyperplastic polyps than IBS subjects, while the prevalence of adenomatous polyps is similar in the two groups.
