| Endoscopic feature | Description |
|---|---|
| Linear furrowing | • Vertical esophageal lines or ridges in the esophageal wall |
| Concentric rings | • Multiple rings that may be fine, web-like or thickened (also termed the “corrugated” or “ringed” esophagus) |
| White speckled exudates |
• Patches of whitish papules (1–2 mm in diameter) • Resembles esophageal candidiasis |
| Schatzki ring | • Narrow ring of tissue located just above the junction of the esophagus and stomach |
| Small-calibre esophagus |
• Narrowed esophagus, with fixed internal diameter • Featureless, unchanging column • Poor expansion on air insufflation • Proximal and/or distal stenosis |
| Linear superficial mucosal tears | • Mucosal abrasions or shearing that occur upon minimal contact (e.g., after simple passage of a routine endoscope) |
