Narrow band imaging of adenocarcinoma arising from ectopic gastric mucosa in the upper esophagus

Abstract

Adenocarcinomas arise rarely in the cervical and upper esophagus [1]. Among these, esophageal adenocarcinomas arising from ectopic gastric mucosa are extremely rare [2] [3] [4]. We report the first patient to undergo magnifying endoscopy with narrow band imaging (NBI) and endoscopic submucosal dissection (ESD) for an esophageal adenocarcinoma arising from ectopic gastric mucosa in the upper thoracic esophagus.
