Evolution of Barrett’s Assessment in a Tertiary Referral Center Over Time

Aims Barrett’s oesophagus is associated with 24 fold increase in risk of Oesophageal cancer. Seattle biopsy protocol is gold standard in Barrett’s surveillance. Adherence to Seattle protocol increases dysplasia detection rate (DDR). In addition, the inclusion of chromoendoscopy with Narrow band imaging (NBI) and Acetic Acid spray (AA) is also associated with improved dysplasia detection rate. Our aim was to review how our assessment of Barrett’s oesophagus with regards to the use of chromoendoscopy, adherence to Seattle Protocol and documentation of Prague classification has evolved over time at our institute and if dysplasia detection rate improved concomitantly.
