    Upper Gastrointestinal Endoscopy

    Risks

    Complications are rare. There is a slight risk that your esophagus, stomach, or upper small intestine will get a small hole in it. If this happens, you may need to have surgery to fix it. There is also a slight chance of infection after an endoscopy.

    Bleeding may also occur from the test or if a tissue sample (biopsy) is taken. But the bleeding usually stops on its own without treatment. If you vomit during the exam and some of the vomit enters your lungs, aspiration pneumonia is a possible risk. If it happens, it can be treated with antibiotics.

    An irregular heartbeat may occur during the test. But it almost always goes away on its own without treatment.

    The risk of problems is higher in people who have serious heart disease, older adults, and those who are frail or physically weakened. Talk to your doctor about your specific risks.

    Results

    An upper gastrointestinal (UGI) endoscopy allows your doctor to look at the inside lining of your esophagus, your stomach, and the first part of your small intestine (duodenum). The doctor uses a thin, flexible viewing tool called an endoscope.

    Your doctor may be able to talk to you about some of the findings right after your endoscopy. But the medicines you get to help relax you may impair your memory, so your doctor may wait until they fully wear off. It may take 2 to 4 days for some results. Tests for certain infections may take several weeks.
