Overview
Initial evaluation of GE junction via flexible fiberoptic esophagosocpy showed irregularity that was markedly enhanced with NBI (narrow band imaging) to improve evaluation and directed biopsy.
Pathology report (edited): Gastroesophageal junction, biopsy: Squamocolumnar junctional mucosa with changes consistent with reflux. No Barrett's metaplasia identified.
The Los Angeles (LA) classification system is in common use to grade reflux esophagitis (Nguyen 2019)
| LA Classification System (Lundell 1999) | |
| Grade | Description |
| A | Mucosal breaks (one or more) ≤ 5 mm length - not extending between the tops of 2 mucosal folds |
| B | Mucosals breaks >5 mm long - not extending between the tops of two mucosal folds |
| C | Mucosal breaks continuous between the tops of 2 or more mucosal folds, involving less than 75% of the circumference |
| D | Mucosal breaks involving 75% or more of the esophageal circumference |
