BACKGROUND/AIMS: Endoscopic definitions and management of Barrett's esophagus vary widely among countries. To examine the current situation regarding diagnosis, epidemiology, management and treatment of Barrett's esophagus in East Asian countries using a questionnaire-based survey.
Representative members of the Committee of the International Gastrointestinal Consensus Symposium developed and sent a questionnaire to major institutions in China, South Korea, Japan, Thailand, Indonesia, and the Philippines.
A total of 56 institutions in the 6 countries participated in the survey. We found that the presence of specialized columnar metaplasia is considered to be important for diagnosing Barrett's esophagus in East Asian countries except for Japan. C&M criteria have not been well accepted in East Asia. The palisade vessels are mainly used as a landmark for the esophagogastric junction in Japan. The prevalence of long segment Barrett's esophagus is extremely low in East Asia, while the prevalence of short segment Barrett's esophagus is very high only in Japan, likely due to different diagnostic criteria.
Among East Asian countries, we found both similarities and differences regarding diagnosis and management of Barrett's esophagus. The findings in the present survey are helpful to understand the current situation of Barrett's esophagus in East Asian countries.
背景/目的：在不同国家之间，对 Barrett 食管的内镜定义和处理方法存在广泛差异。本研究旨在通过问卷调查，考察东亚国家 Barrett 食管的诊断、流行病学、管理和治疗现状。
国际胃肠共识研讨会委员会的代表性成员制定并向中国、韩国、日本、泰国、印度尼西亚和菲律宾的主要机构发送了一份调查问卷。
来自 6 个国家的 56 家机构参与了这项调查。我们发现，东亚国家（日本除外）认为存在特殊的柱状上皮化生对于 Barrett 食管的诊断非常重要。C&M 标准在东亚尚未得到广泛认可。在日本，栅状血管主要用作食管胃交界的标志。东亚长节段 Barrett 食管的患病率极低，而短节段 Barrett 食管的患病率在日本非常高，这可能是由于不同的诊断标准所致。
在东亚国家中，我们发现 Barrett 食管的诊断和管理既有相似之处，也存在差异。本研究中的调查结果有助于了解东亚国家 Barrett 食管的现状。
