  • Abstract
  • Look Inside

 Evaluation of esophagitis with gastro-esophageal reflux was made by endoscopic ultrasonography (EUS). In patients with reflux esophagitis, there are variable findings observed by EUS on the third and fourth layers of the esophageal wall. Particularly, severe stenosis of the esophagus due to esophagitis is observed. The third and fourth layers of the esophageal wall were visualized on the EUS as thick, smooth, and homogenous echo levels. Histological study in resected cases revealed fibrosis of the submucosal and muscle layers. It was suggested that on the EUS observation the fibrotic changes of the esophageal wall made the echo levels of the third and fourth layers similar to each other. The reflux esophagitis was classified into three types by EUS.
