Endoscopy result normal ,findings : long history of reflux, jagged z line noted suggestive of gord (no active imflammation seen) relavance of z line?

Line of demarcation: The Z line is the area where the lining cells of the esophagus stop and the lining cells of the stomach start. People with an irregular or "jagged" z line have a slightly increased risk of developing pre-cancerous changes along the z line. The fact that yours showed no inflammation is very reassuring. Hope this was helpful. Dr R
