Common GERD symptoms: heartburn, regurgitation
Atypical symptoms include chest pain, odynophagia, chronic cough, water brash, globus sensation, laryngiti...
The goal of medical therapy is to control GERD and reduce esophagitis.

Figure 21-8. A: Low-power picture of an invasive cancer at the cardioesophageal junction (open arrow). It is bordered by a metaplastic Barrett's mucosa (closed arrow) arranged in villus folds. B: Detail of intestinal-type epithelium with many goblet cells on the surface of these folds. The core of one fold is invaded by the carcinoma (arrow).

<bold><italic>Figure 15-9</bold> Barrett esophagus.</bold> Normal esophagus is lined by layers of flat, squamous epithelium. Normal stomach is lined by tall, columnar cells. Chronic reflux of gastric acid evokes change (metaplasia) of normal esophageal squamous epithelium into gastric epithelium (Barrett metaplasia). Esophageal ulcers and adenocarcinoma may arise in areas of Barrett metaplasia.
