Abstract
BACKGROUND & AIM: Intestinal metaplasia in Barrett's epithelium has been shown to be associated with adenocarcinoma. It is, however, difficult to endoscopically detect intestinal metaplasia in Barrett's epithelium. The aim of this study was to evaluate the usefulness of methylene blue staining for detecting intestinal metaplasia in Barrett's epithelium. METHODS: We performed upper endoscopy with methylene blue-directed biopsy and obtained 83 biopsy specimens (57 stained and 26 unstained) from 24 Japanese patients with Barrett's epithelium, 1 cm or more in length. All specimens were examined histologically. RESULTS: The sensitivity and specificity of methylene blue staining for detecting intestinal metaplasia were 98.2% and 92.6%, respectively. Patients with short or limited length of Barrett's epithelium have a focal distribution of intestinal metaplasia. CONCLUSIONS: Methylene blue staining is a useful method for detecting intestinal metaplasia in Barrett's epithelium and may aid the endoscopist in selective biopsies from Barrett's epithelium.
