Upper Gastrointestinal Endoscopy

What Affects the Test

You may not be able to have the test, or the results may not be helpful, if you just had another test that uses barium contrast material. An upper gastrointestinal endoscopy should not be done less than 2 days after you have a type of X-ray test called an upper gastrointestinal (GI) series so your doctor can see your stomach and small intestine.

What To Think About

  • An upper gastrointestinal (GI)endoscopy is the best way to examine your esophagus, stomach, and upper small intestine (duodenum). Your doctor can take a tissue sample to test for H. pylori infection, which is believed to be the main cause of stomach or duodenal ulcers. To learn more, see the topic Helicobacter Pylori Tests.
  • Cancer can be found or ruled out using endoscopy.
  • Endoscopy may be done after an upper GI series test finds a problem. To learn more, see the topic Upper Gastrointestinal Series.
  • Small children can safely have endoscopy.
