New developments for endoscopic management of Barrett's esophagus with high grade dysplasia / 浙江大学学报·医学版

ABSTRACT

Barrett's esophagus is now clearly recognized as a preneoplasic condition. Progression of metaplasia through dysplasia to adenocarcinoma is a widely accepted theory for esophageal carcinogenesis. That high grade dysplasia is frequently found in association with esophageal adenocarcinoma. Long-term endoscopic surveillance of high grade dysplasia in Barrett's esophagus facilitates detection and treatment of esophageal cancers in the early stage.
