Schatzki’s Rings – mucosa and submucosa connective tissue ring obstructs esophageal lumen. Mostly located at the esophageal junction. Esophageal Webs – thin, fibrous membranes transversing the upper esophageal lumen. Plummer-Vinson syndrome is associated with esophageal webs but also has iron-deficient anemia, glossitis, and splenomegaly.

The macroscopic EGJ often does not correspond to the junction of esophageal squamous mucosa and columnar mucosa because of the common finding in esophageal resection specimens of glandular mucosa involving the distal esophagus. Because anatomic divisions of the esophagus are defined by anatomic boundaries and relationships to other structures,1 ...

15% of adults report symptoms consistent with this; in this disease, the (usually closed) LES fails to remain closed or remain closed completely; this allows the very high concentration of gastric acid to “go backward” and reflux into the distal esophagus; this causes indigestion or heartburn; in fact, indigestion can be thought of simplistically as a chemical burn of the more delicate ...

Glandular metaplasia of squamous epithelium (Barrett’s esophagus) carries increased risk of esophageal cancer. MUCOSAL TEARS. Retching and vomiting lacerates mucosa, which may bleed profusely. CARCINOMA OF ESOPHAGUS. Squamous cell carcinoma gradually narrows lumen. May invade trachea and cause fistula. FOOD IMPACTION

The causes of bleeding in patients hospitalized for upper GI bleeding are a) peptic ulcer disease (31-67%), b) esophageal varices (in cirrhosis) (6-39%); c) Mallory-Weiss tears of the gastro-esophageal junction (2-8%); d) gastric and/or duodenal erosions (small ulcers) (2-18%); e) esophagitis severe enough to cause erosions of the mucosa, also called erosive esophagitis (1-13%); f) esophageal ...
Esophagus
Extension of the inflammatory process into the muscularis propria causes a progressive loss in the length and pressure of the distal esophageal high-pressure zone associated with an increased esophageal exposure to gastric juice and the symptoms of heartburn and regurgitation.
