2. The removal of a portion of the lower esophagus and proximal stomach for treatment of neoplasms or strictures of those organs; especially, lesions at or near the cardioesophageal (the cardia or stomach immediately adjacent to and surrounding the cardiac or primary opening of the esophagus of the stomach and the esophagus) junction.

The objective of using an esophagogastroduodenoscope is to identify ulcers, gastritis, esophagitis, varices, duodenitis, Barrett's esophagus, hiatal hernias, and tumors.
A esophagogastroduodenoscope procedure is performed on patients with a variety of symptoms; that include: nausea, vomiting, abdominal bloating, abdominal pain, heartburn, reflux, family history of cancer, jaundice, weight loss, anemia, and gastrointestinal bleeding.
For endoscopy, a flexible opitical instrument (the endoscope) is inserted through the mouth and advanced into the esophagus, the stomach, and the duodenum (the first part of the small intestine).
Pathologicl changes (diseases, if any) are also evaluated by inflating air into the digestive tract.
An esophagogram can also be explained as being a radiographic record of contrast by esophagography or by a barium swallow, which is an oral administration of barium sulfate suspension for radiographic investigation of the esophagus.
2. The technique of obtaining an esophagogram: In her class at medical school, Peggy learned that esophagography used the method of diagnostic imaging of the esophagus.
