What do the results of an upper GI endoscopy mean?

  • AHealthwise answered

    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 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 duodenum. 


    • A hiatal hernia is found. 
    • A too-narrow (stricture) section is found in the esophagus.
    • 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 cells.
    • 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.
