Upper Gastrointestinal Endoscopy
How It Is Done continued...
test, you may get a pain medicine and a
sedative through an intravenous (IV) line in your arm
or hand. These medicines reduce pain and will make you feel relaxed and
drowsy during the test. You may not remember much about the actual test.
You will be asked to lie on your left side with your head bent
slightly forward. A mouth guard may be placed in your mouth to protect your
teeth from the endoscope (scope). Then the lubricated tip of the scope will be
guided into your mouth. Your doctor may gently press your tongue out of the
way. You may be asked to swallow to help move the tube along. The scope is no thicker than many foods you swallow. It will
not cause problems with breathing.
After the scope is in your
esophagus, your head will be tilted upright. This makes it easier for the scope
to slide down your esophagus. During the procedure, try not to swallow unless
you are asked to. Someone may remove the saliva from your mouth with a suction
device. Or you can allow the saliva to drain from the side of your mouth.
Your doctor will look through an eyepiece or watch a screen while he or she slowly moves the endoscope. The doctor will check the walls of your
esophagus, stomach, and duodenum. Air or water may be injected through the
scope to help clear a path for the scope or to clear its lens. Suction may
be applied to remove air or secretions.
A camera attached to the scope takes pictures. The doctor may also insert tiny tools such as forceps, clips, and
swabs through the scope to collect tissue samples (biopsy), remove
growths, or stop bleeding.
To make it easier
for your doctor to see different parts of your upper gastrointestinal (GI)
tract, someone may change your position or apply gentle pressure to your belly.
After the exam is done, the scope is slowly withdrawn.
After the test
The test usually takes 30 to 45
minutes. But it may take longer, depending upon what is found and what is done
during the test.
