Abstract
OBJECTIVE
In the areas where intestinal metaplasia of the stomach is highly
prevalent, diagnosing Barrett's esophagus solely by the presence of specialized
columnar epithelium in the distal esophagus may lead to many false positive
diagnoses. The aim of this study was to test validity of the specialized
columnar epithelium as a diagnostic criterion of the short segment Barrett's
esophagus in Korea. METHODS: During routine gastroscopy, the length of
columnar-lined esophagus was measured and biopsy samples were taken from the
mucosa immediately distal to the squamocolumnar junction. Under light
microscopy, alcian blue-positive cells were identified. RESULTS: Prevalence of
the specialized columnar epithelium in cases without the columnar-lined
esophagus and with the short segment columnar-lined esophagus were 57.1% and
31.2%, respectively (P = 0.0281). The specialized columnar epithelium is
frequently seen around the cardia in Koreans with or without the columnar-lined
esophagus. CONCLUSION: Simple presence of the specialized columnar epithelium is
not a valid criterion for a diagnosis of Barrett's esophagus. We propose that
both the short segment Barrett's esophagus and the goblet cell metaplasia of the
cardia might be grouped together under a title of "the specialized columnar
epithelium around the gastroesophageal junction" as a potential preceding
condition of adenocarcinoma around the cardia.
