Using the endoscope, your doctor examines your esophagus, looking for cancer or areas of irritation. During endoscopy, your doctor passes a flexible tube equipped with a video lens (videoendoscope) down your throat and into your esophagus. Using a scope to examine your esophagus (endoscopy).The barium coats the inside of your esophagus, which then shows any changes to the tissue on the X-ray. During this study, you swallow a liquid that includes barium and then undergo X-rays. Tests and procedures used to diagnose esophageal cancer include: A tiny camera on the end of the endoscope allows views of your esophagus, stomach and the beginning of your small intestine, called the duodenum. Typically you can get the results within a day or two.An endoscopy procedure involves inserting a long, flexible tube called an endoscope down your throat and into your esophagus. How long is it before the result of the test is known? Your stool may appear light in color for a couple of days.

Must I do anything special after the test is over?Īfter the test, you can eat normally and do your normal activities. You are exposed to a small amount of radiation during the test, but the amount of radiation is too small to be likely to cause any health problems. You are asked to hold your breath for each picture so that your breathing movement does not blur the image. The x-ray machine or the table is moved a few times so it can take pictures of all of the internal structures. Most often, the x-ray pictures are taken while you lie on your back on a table. The x-ray technician may ask you to stand or lie in different positions over the next few minutes, to help spread around the liquid you have swallowed. You will get better pictures if you can keep yourself from burping. This might make you feel like burping, but try not to. You might also be asked to swallow some tablets that "fizz," causing air-bubbles to be released in your stomach. At the start of the test, you drink barium, a liquid that looks like a milk shake but does not taste nearly as good (most patients say it tastes like chalk). Usually it isn't a problem for you to take most of your regular pills, but you should check with your doctor. This is important because food in your stomach or intestine could prevent the doctors from seeing a clear outline of these structures on the x-rays.

This test is useful to help evaluate potential problems in the esophagus, stomach and first part of the intestine. The barium temporarily coats the lining of the esophagus, stomach, and intestine, making the outline of these organs visible on the x-ray pictures. Because these organs are normally not visible on x-rays, you need to swallow barium, a liquid that does show up on x-rays. A barium swallow, or upper GI series, is an x-ray test used to examine the upper digestive tract (the esophagus, stomach, and small intestine).
