title: Review: Barrett's oesophagus in Taiwan.
abstract: Barrett's oesophagus is the eponym applied to the columnar epithelium-lined lower oesophagus which is acquired as a complication of chronic gastro-oesophageal reflux (GER). Various complications seen in the Barrett's oesophagus, such as peptic ulcer, stricture, adenocarcinoma are named as Barrett's ulcer, Barrett's stricture-and Barrett's carcinoma, respectively. It is now generally accepted that Barrett's oesophagus is an acquired condition resulting from chronic repetitive GER. The frequency of Barrett's oesophagus seems to be higher in Caucasian than in Oriental or Negro populations. There is a tendency towards increasing prevalence rates all over the world, including Taiwan, due to the Westernization of diet, rapid growth in the elderly population, obesity etc. Almost 6% of the patients who manifest heartburn in GI clinics in Taiwan now suffer from GER, which is almost similar to the 7% reported by Nabel, (USA) in 1976. During the last 30 years, the incidence of esophageal adenocarcinoma has increased rapidly. Patients with Barrett's oesophagus have an increased risk of developing oesophageal adenocarcinoma and should be kept under surveillance. Regular follow-up, at least twice a year or preferably, every 2-3 months, for those patients with SCE using endoscopic surveillance and biopsy for those with severe dysphasia (oesophageal columnar intraepithelial neoplasia) in the surrounding area to detect Barrett's oesophagus cancer, is very important.
