Abstract

Background: Depending on the length of the segment of columnar epithelium in the distal oesophagus, Barrett's oesophagus can be divided into long-segment and short-segment Barrett's oesophagus. This article describes the pathophysiological characteristics of both forms of Barrett's oesophagus. Methods: Review of the literature. Results: Although there is some disagreement, ours and most other studies suggest that long-segment columnar-lined oesophagus is causally linked to chronic gastro-oesophageal reflux and that this from of Barrett's oesophagus is characterized by lower oesophageal sphincter tone, reduced oesophageal contractility and increased acid reflux. Short-segment Barrett's oesophagus is also associated with acid reflux, but the degree of oesophageal acid exposure and the level of other pathophysiological alterations seem to be lower. Conclusion: Pathophysiological abnormalities appear to be more prominent in long-segment Barrett's oesophagus than in short-segment Barrett's oesophagus.
