Barrett's oesophagus

Presentation of Barrett's oesophagus may be asymptomatic, but it typically occurs in middle-aged white men who have had chronic gastro-oesophageal reflux disease (GORD). Additional risk factors include tobacco use and obesity.

Cancer risk is determined by the degree of dysplasia.

Endoscopic screening and surveillance programmes have multiple shortcomings. Screening of the general population is not recommended, and surveillance intervals vary depending on histological findings.

Proton-pump inhibitors are commonly used to control GORD symptoms and may reduce the risk of neoplastic Barrett's oesophagus.

Endoscopic therapies play a central role in the management of dysplastic Barrett's oesophagus and early oesophageal adenocarcinoma.

Barrett's oesophagus is a change in the normal squamous epithelium of the oesophagus to specialised intestinal metaplasia.[1]Fitzgerald RC, di Pietro M, Ragunath K, et al.
