[Epidemiology of Barrett's esophagus--comparison of Japan and the West].
We compared the epidemiology of Barrett's esophagus in Japan and the West. Japan GERD Society Study Committee conducted the epidemiological survey in 2,595 patients who underwent endoscopy the first time, confirming that Barrett's mucosa was observed in 536 patients (20.8%) out of 2,577. ⋯ In Western, the incidence of Barrett's esophagus has increased markedly since the 1970s. It is estimated that Barrett's esophagus is found in approximately 6-12% of patients undergoing endoscopy for symptoms of GERD and in 1% or less of unselected patient populations undergoing endoscopy.
