endoscopy, EGD (esophagogastroduodenoscopy): A flexible tube with a camera
on its end (endoscope) is inserted through the mouth. The endoscope allows
examination of the stomach and duodenum (small intestine).
pH monitoring: A probe that monitors acidity (pH) is introduced into the
esophagus. Monitoring pH can help identify GERD and follow the response to
swallow: A person swallows a barium solution, then X-ray films are taken of
the esophagus and stomach. Most often, a barium swallow is used to seek the
cause of difficulty swallowing.
H2 blockers: Histamine stimulates acid release in the stomach. Certain
antihistamines called H2 blockers can reduce acid, improving GERD and
Proton pump inhibitors: These medicines turn off many of the acid-producing
pumps in the stomach wall. Reduced stomach acid can reduce GERD symptoms, and
help ulcers or esophagitis to heal.
Esophagectomy: Surgical removal of the esophagus, usually for esophageal
Esophageal dilation: A balloon is passed down the esophagus and inflated to
dilate a stricture, web, or ring that interferes with swallowing.
Esophageal variceal banding: During endoscopy, rubber band-like devices can
be wrapped around esophageal varices. Banding causes varices to clot, reducing
their chance of bleeding.
Often done through an endoscope, a small piece of the esophagus is taken to be
evaluated under a microscope.
