Risk factors associated with Barrett's epithelial dysplasia.

Aim: To elucidate risk factors associated with dysplasia of short-segment Barrett's esophagus (BE).

Methods: A total of 151 BE patients who underwent endoscopic examination from 2004 to 2008 in Aoyama Hospital, Tokyo Women's Medical University, Japan and whose diagnosis was confirmed from biopsy specimens were enrolled in the study. BE was diagnosed based on endoscopic findings of gastric-appearing mucosa or apparent columnar-lined esophagus proximal to the esophagogastric junction.
