Bleeding may also happen 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 test and some of the vomit enters your lungs, aspiration pneumonia is a possible risk.

Whatismicroscopein science

The doctor puts the tip of the scope in your mouth and gently moves it down your throat. The scope is a flexible video camera. The doctor looks at a monitor (like a TV set or a computer screen) as he or she moves the scope. A doctor may do this procedure to look for ulcers, tumours, infection, or bleeding. It also can be used to look for signs of acid backing up into your esophagus. This is called gastroesophageal reflux disease, or GERD. The doctor can use the scope to take a sample of tissue for study (a biopsy). The doctor also can use the scope to take out growths or stop bleeding.

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.

To make it easier for your doctor to see different parts of your upper GI tract, someone may change your position or apply gentle pressure to your belly. After the examination is done, the scope is slowly pulled out.

If you or someone in your care has chest pains, difficulty breathing, or severe bleeding, it could be a life-threatening emergency. Call 9-1-1 or the local emergency number immediately.

The suction machine that's used to remove secretions may be noisy, but it doesn't cause pain. The removal of biopsy samples is also painless.

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.

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.

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.

During the test, you may feel very drowsy and relaxed from the sedative and pain medicines. You may have some gagging, nausea, bloating, or mild cramping in your belly as the tube is moved. If you have pain, alert your doctor with an agreed-upon signal or a tap on the arm. Even though you won't be able to talk during the procedure, you can still communicate.

You will feel groggy after the test until the medicine wears off. This usually takes a few hours. Many people report that they remember very little of the test because of the sedative given before and during the 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 may notice a brief, sharp pain when the intravenous (IV) needle is placed in a vein in your arm. The local anesthetic sprayed into your throat usually tastes slightly bitter. It will make your tongue and throat feel numb and swollen. Some people report that they feel as if they can't breathe at times because of the tube in their throat. But this is a false sensation caused by the anesthetic. There is always plenty of breathing space around the tube in your mouth and throat. Remember to relax and take slow, deep breaths.

An upper gastrointestinal (or GI) endoscopy is a test that allows your doctor to look at the inside of your esophagus, stomach, and the first part of your small intestine, called the duodenum. The esophagus is the tube that carries food to your stomach. The doctor uses a thin, lighted tube that bends. It is called an endoscope, or scope.
