  1. The prevalence of colonic neoplasia in patients with Barrett's esophagus : Prospective assessment in patients 50-80 years old.

    Article - En anglais


    An association between Barrett's esophagus and colorectal neoplasia has been suggested ; however, several studies addressing this issue have reported conflicting results.

    The purpose of this study, therefore, was to determine the prevalence of colorectal neoplasia in a large group of patients (50-80 yr old ; mean, 65 yr) with Barrett's esophagus and compare it with that of a similar group of asymptomatic, average-risk controls.


    Seventy-nine subjects (71 men, eight women) with well-documented Barrett's esophagus underwent complete colonoscopy (cecum reached), which was performed as part of an initial screening evaluation for enrollment in a prospective study of Barrett's esophagus.

    The control population (N=930) is represented by the cumulative results of four recent studies in which screening colonoscopy was performed in asymptomatic subjects of average risk.

    The age of the two groups were similar.


    A total of 38 adenomatous polyps were found in 26 patients in the study group.

    Three patients (4%) had polyps>1 cm in size or with villous change, which was similar to the prevalence among asymptomatic controls (5%). The overall prevalence of colon adenomas was 32%, and the prevalence of colorectal cancer was 1% in the Barrett's group.

    In the control group, 30% had adenomas and 0.5% had cancer. (...)
