Gastroesophageal reflux disease
Diagnosis in short

Micrograph showing histology compatible with gastroesophageal reflux disease. H&E stain.

LM basal cell hyperplasia (> 3 cells thick or >15% of epithelial thickness), papillae elongated (papillae reach into the top 1/3 of the epithelial layer), inflammation, esp. eosinophils, lymphocytes with convoluted nuclei ("squiggle cells"), +/-intraepithelial edema, +/-apoptotic cells, +/-glycogenation
LM DDx intestinal metaplasia (Barrett's esophagus), eosinophilic esophagitis, acute esophagitis
Site esophagus

Associated Dx obesity, Barrett's esophagus
Prevalence common
Endoscopy erythema, erosions, +/-ulceration.
Prognosis benign
Clin. DDx eosinophilic esophagitis, acute esophagitis
Treatment proton pump inhibitors

Gastroesophageal reflux disease, abbreviated GERD, is a common pathology of the esophagus. It is occasionally abbreviated GORD (gastro-oesophageal reflux disease).

Reflux esophagitis redirects here. It technically isn't a synonym.[1][2]

General

Clinical:

  • Usually chest pain
  • +/-Abdominal pain.
  • +/-Vomiting.
  • +/-Blood loss.

Treatment:

DDx (clinical):

Gross

  • Erythema.
  • Erosions.
  • +/-Ulceration.

Note:

  • Many be graded using Savary-Miller classification or Los Angeles classification.[3]

Los Angeles classification for GERD

Features:[4]

Classification Description
A mucosal break <=5 mm, not beyond the tops of two (adjacent) mucosal folds
B mucosal break >5 mm, not beyond the tops of two (adjacent) mucosal folds
C mucosa break beyond the tops of two mucosal folds but <75% of the esophageal circumference
D mucosal break >=75% of the esophageal circumference

Note:

  • Correlation with histology is poor; mucosal breaks are seen rarely.[3]

Microscopic

Features:

  1. Basal cell hyperplasia;[5] > 3 cells thick or >15% of epithelial thickness.
  2. Papillae elongated; papillae reach into the top 1/3 of the epithelial layer.[6]
  3. Inflammation, esp. eosinophils, lymphocytes with convoluted nuclei ("squiggle cells").
  4. +/-Intraepithelial edema.
  5. +/-Apoptotic cells.[7]
  6. +/-Glycogen - cytoplasm cleared (white).[8]

Notes:

  • Intraepithelial cells with irregular nuclear contours, "squiggle cells" (T lymphocytes[9]), may mimic neutrophils.
  • Changes may be focal.
  • PPI effect may be seen in a concurrent gastric biopsy.
  • Perinuclear clearing may be seen.[10]

  INTRAEPITHELIAL EOSINOPHILS AND EVIDENCE OF ULCERATION -- COMPATIBLE WITH
  GASTROESOPHAGEAL REFLUX.
- COLUMNAR EPITHELIUM WITH MODERATE CHRONIC INACTIVE INFLAMMATION.
- NEGATIVE FOR INTESTINAL METAPLASIA.
- NEGATIVE FOR DYSPLASIA AND NEGATIVE FOR MALIGNANCY.

COMMENT:
PAS-D staining is negative for microorganisms.

BE and GERD present

ESOPHAGUS (DISTAL), BIOPSY:
- COLUMNAR EPITHELIUM WITH INTESTINAL METAPLASIA AND MODERATE CHRONIC INFLAMMATION,
  SEE COMMENT.
- SQUAMOUS MUCOSA WITH BASAL CELL HYPERPLASIA, INTRAEPITHELIAL EDEMA AND RARE
  INTRAEPITHELIAL EOSINOPHILS -- COMPATIBLE WITH GASTROESOPHAGEAL REFLUX.
- NEGATIVE FOR DYSPLASIA AND NEGATIVE FOR MALIGNANCY.

COMMENT:
The findings are consistent with Barrett's esophagus in the appropriate endoscopic setting.
