An esophagogastroduodenoscopy or EGD test is also called the upper endoscopy that helps doctors examine the upper part of the gastrointestinal tract to treat symptoms and conditions affecting the esophagus, stomach, and upper intestine or duodenum.

EGD test or Endoscopy is a painless process. Your doctor will insert the endoscope, a long, thin, flexible pipe fitted with a tiny camera and light at its leading tip, into your mouth and push it gently through your throat. You may be asked to swallow as the scope passes down your throat.

As the endoscope is forwarded down your esophagus, the images from the camera will be shown on a monitor. Your doctor will observe the image minutely to find out if there is any abnormality in your upper digestive tract. Gentle air pressure may be used to inflate your digestive tract. This allows the endoscope to move freely inside the tract.

If any polyps are found they are removed by the doctor using a special surgical tool passed through the endoscope, and then sent for malignancy test.

Once the doctor has finished the test, the endoscope is carefully retracted through your mouth. The entire process typically takes around 30 minutes, depending on your situation. The endoscope doesn't interfere with your breathing.
