False about Barrett’s oesophagus is:
Barrett’s ulcer is an ulcer in the columnar lined portion of a Barrett’s oesophagus.
These are distinct from the more usual erosions of reflux oesophagitis that always occur at or just above the squamocolumnar junction.
In short – segment Barrett’s there is less than 3 cm of columnar epithelium
Barrett’s ulcer occurs just above the squamocolumnar junction
If a peptic stricture occurs in Barrett’s oesophagus it always occurs at the new squamocolumnar junction
It is a premalignant condition
