Upper Gastrointestinal Endoscopy
An upper gastrointestinal (UGI)
endoscopy is a procedure that allows your doctor to look at the interior lining
of your esophagus, your stomach, and the first part of your small intestine
(duodenum) through a thin, flexible viewing instrument
called an endoscope.
Your doctor may be able to talk to you about
some of the findings with you immediately after your upper gastrointestinal
endoscopy. But the medicines given to help relax you may impair your
memory, so your doctor may wait until they wear off completely. Other
results are usually available in 2 to 4 days. Tests for certain infections may
take several weeks.
Upper gastrointestinal endoscopy
The esophagus, stomach, and upper small
intestine (duodenum) look normal.
Inflammation or irritation is found in the
esophagus (esophagitis), stomach (gastritis), or small intestine.
Bleeding, an ulcer, a tumor, a tear, or
dilated veins (esophageal varices) are found in the esophagus, stomach, or
hiatal hernia is found.
A too-narrow (stricture) section is found in
A foreign object is found in
the esophagus, stomach, or duodenum.
A biopsy sample may be taken to:
- Find out if tumors or ulcers contain cancer
- Identify a type of bacteria called
Helicobacter pylori (H. pylori).
Many conditions can change the results of an upper
gastrointestinal endoscopy. Your doctor will talk with you about any abnormal
results that may be related to your symptoms and past health.
What Affects the Test
Reasons you may not be able to
have the test or why the results may not be helpful include the
- 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 an upper gastrointestinal
(GI) series so your doctor can see your stomach and small

What To Think About
- An upper gastrointestinal 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 Helicobacter pylori infection, which is believed to be the main cause of stomach or
duodenal ulcers. For more information, see the topic
Helicobacter Pylori Tests.
- Cancer can be identified or ruled out using endoscopy.
- Endoscopy may be done after an upper gastrointestinal series test
identifies a problem. For more information, see the topic
Upper Gastrointestinal Series.
can be safely performed on small children.
- Endoscopic retrograde
cholangiopancreatogram (ERCP) is a test of the ducts that drain the liver,
pancreas. It can be done to find the cause of
jaundice if your doctor thinks you may have blockage
of the bile or pancreatic ducts and when other tests (such as
ultrasound, liver scan, and X-ray studies) are not
clear. For more information, see the topic
Endoscopic Retrograde Cholangiopancreatogram (ERCP).
