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

Bleeding, an ulcer, a tumor, a tear, or

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. To learn more, 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. To learn more, 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. To learn more, see the topic Endoscopic Retrograde Cholangiopancreatogram (ERCP).
