How the test is performed
You will be given a sedative and an
In most cases, an intravenous line will be inserted into your arm to administer medications during the procedure.
You will be instructed to lie on your left side.
After the sedatives have taken effect:
- The endoscope is advanced through the esophagus (food pipe) to the stomach and
duodenum. Air is introduced through the endoscope to enhance viewing.
- The lining of the esophagus, stomach, and upper duodenum is examined, and
biopsiescan be taken through the endoscope. Biopsies are tissue samples that are reviewed under the microscope.
- Different treatments may be performed, such as stretching or widening a narrowed area of the esophagus.
After the test is completed, food and liquids will be restricted until your gag reflex returns (so you don't choke).
