Global prevalence of Barrett’s oesophagus and oesophageal cancer in individuals with gastro-oesophageal reflux: a systematic review and meta-analysis
There has been no definitive systematic review and meta-analysis of data to estimate global prevalence of Barrett's oesophagus. Prevalence of BO among individuals with gastro-oesophageal reflux varied according to different geographical regions. Dysplasia was present in 13.9% of cases of histologically confirmed BO, 80.7% of which was low-grade. The prevalence of BO was significantly higher in men than in women.
