Esophagus: Normal Squamo-columnar Junction

Esophagitis (Inflammation and Reactive Epithelial
Changes of the Esophageal Mucosa) Has Many Causes
![Page 5: Esophagus: Normal Lower Esophageal and Squamo- columnar Junction Mucosae](https://reader030.vdocuments.site/reader030/viewer/2022032707/56649e0e5503460f94af8f07/html5/thumbnails/5.jpg)
Reflux Esophagitis is the Culmination of Gastro-
Esophageal Reflux-Induced Changes in Epithelial Cell
Turnover

Esophagus: G-E Reflux - Changes in Epithelium and
Vascular Papillae

Esophagus: G-E Reflux - Defenses Against Reflux-
induced Injury

Esophagus: G-E Reflux - Symptoms and Endoscopic Findings in Reflux are NOT
Predictive of Biopsy Findings

Esophagus: G-E Reflux - Heightened Epithelial
Turnover in G-E Reflux is Shown by Increased Epithelial Tritiated Thymidine Labeling

Esophagus: G-E Reflux - Reflux-induced Epithelial
Change Is a Consequence Of Increased Cell Turnover
