Barrett’s oesophagus
a change in cell type: from esophageal squamous to specialized intestinal metaplasia
Aetiology: Caused by chronic GE reflux
Epidemiology:
- 10-20% of men scoped for chronic reflux have Barret Oesophagus
- 2% of women have it
- Most common in Caucasian men > 50yrs with long standing (>10yrs) indigestion
Surveillance screening – not supported
Risk factors
- Inc ing age >40yrs
- male sex
- history of frequent GORD
- Abdominal central obesity
- Smoking
Other: Fhx of oesophageal adenocarcinoma &/or Barrett’s oesophagus
Associations
Adenocarcinoma (30x risk)
- risk related to length of Barret oesophagus, presence of hiatal hernia, degree of dysplasia & concurrent smoking
- risk is 0.4%/yr
- Anti reflux medication & surgery will NOT reverse the epithelial changes of barretts or eliminate risk of cancer
Treatment
High grade dysplasia
- endoscopic eradication with radiofrequency ablation (RFA) or endoscopic mucosal resection (EMR). Photodynamic therapy is occasionally used.
- Esophagectomy is an alternative for high grade dysplasia but has higher morbiditiy
Follow up endoscopic surveillance (with biopsy)
As per 2011 ACG guideline:
- No dysplasia 3-5yrs
- Low grade dysplasia 6-12 months
- High grade dysplasia in absence of eradication therapy 3 months
