Upper Gastrointestinal Endoscopy

Upper Gastrointestinal Endoscopy

Test Overview

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 character of your small intestine, called the duodenum. The esophagus is the tube that carries food to your stomach. The doctor uses a sparse, lighted tube that bends. It is called an endoscope, or telescope .
The doctor puts the tip of the oscilloscope in your mouth and lightly moves it down your throat. The setting is a flexible television camera. The repair looks at a monitor ( like a television receiver set or a calculator screen ) as he or she moves the telescope. A doctor may do this routine to look for ulcers, tumors, infection, or bleeding. It besides can be used to look for signs of acid backing up into your esophagus. This is called gastroesophageal ebb disease, or GERD. The doctor can use the scope to take a sample of weave for study ( a biopsy ). The repair besides can use the oscilloscope to take out growths or stop bleeding .

Why It Is Done

An upper GI endoscopy may be done to :

  • Find what’s causing you to vomit blood.
  • Find the cause of symptoms, such as upper belly pain or bloating, trouble swallowing (dysphagia), vomiting, or unexplained weight loss.
  • Find the cause of an infection, such as helicobacter pylori (H. pylori).
  • Find problems in the upper gastrointestinal (GI) tract. These problems can include:
    • Inflammation of the esophagus ( esophagitis) or the stomach ( gastritis) or intestines (Crohn’s disease).
    • Gastroesophageal reflux disease ( GERD ).
    • Celiac disease.
    • A narrowing (stricture) of the esophagus.
    • Enlarged and swollen veins in the esophagus or stomach. (These veins are called varices.)
    • Barrett ‘s esophagus, a condition that increases the risk for esophageal cancer.
    • Hiatal hernia.
    • Ulcers.
    • Cancer.
  • Check the healing of stomach ulcers.
  • Look at the inside of the stomach and upper small intestine (duodenum) after surgery.
  • Look for a blockage in the opening between the stomach and duodenum.

endoscopy may besides be done to :

  • Check for an injury to the esophagus in an emergency. (For example, this may be done if the person has swallowed poison.)
  • Collect tissue samples ( biopsy) to be looked at in the lab.
  • Remove growths (polyps) from inside the esophagus, stomach, or small intestine.
  • Treat upper GI bleeding that may be causing anemia.
  • Remove foreign objects that have been swallowed or food that is stuck.
  • Treat a narrow area of the esophagus.
  • Treat Barrett’s esophagus.

How To Prepare

Procedures can be nerve-racking. This data will help you understand what you can expect. And it will help you safely prepare for your procedure .

Preparing for the procedure

  • Do not eat or drink anything for 6 to 8 hours before the test. An empty stomach helps your doctor see your stomach clearly during the test. It also reduces your chances of vomiting. If you vomit, there is a small risk that the vomit could enter your lungs. (This is called aspiration.) If the test is done in an emergency, a tube may be inserted through your nose or mouth to empty your stomach.
  • Do not take sucralfate (Carafate) or antacids on the day of the test. These medicines can make it hard for your doctor to see your upper GI tract.
  • If your doctor tells you to, stop taking iron supplements 7 to 14 days before the test.
  • Be sure you have someone to take you home. Anesthesia and pain medicine will make it unsafe for you to drive or get home on your own.
  • Understand exactly what procedure is planned, along with the risks, benefits, and other options.
  • Tell your doctor ALL the medicines, vitamins, supplements, and herbal remedies you take. Some may increase the risk of problems during your procedure. Your doctor will tell you if you should stop taking any of them before the procedure and how soon to do it.
  • If you take aspirin or some other blood thinner, ask your doctor if you should stop taking it before your procedure. Make sure that you understand exactly what your doctor wants you to do. These medicines increase the risk of bleeding.
  • Make sure your doctor and the hospital have a copy of your advance directive. If you don’t have one, you may want to prepare one. It lets others know your health care wishes. It’s a good thing to have before any type of surgery or procedure.

inflammation or annoyance is found in the esophagus, stomach, or little intestine .
Bleeding, an ulcer, a tumor, a tear, or dilated veins are found .

A too-narrow section ( stenosis ) is found in the esophagus .
A alien object is found in the esophagus, stomach, or little intestine .
A biopsy sample may be taken to :

  • Find the cause of inflammation.
  • Find out if tumors or ulcers contain cancer cells.
