BARIUM STUDIES

The gastrointestinal tract (or the GI tract) is not visible well by x-rays, and so it becomes necessary to introduce some special media within the GI tract so that, the esophagus, stomach and small intestines are clearly visible while diagnosis. For this, barium sulphate is mixed with water (flavoring agent addition is optional) and is swallowed. It may be also introduced as an enema through a tube inserted in the rectum. The mixture passes quickly in the digestive tract and, its pathway is then followed with the aid of x-rays.

A barium swallow can help to diagnose swallowing or reflux problems. A barium enema is used to diagnose problems affecting your large bowel. Barium study is especially helpful in the following cases:

1. The abnormal shape of the digestive tract can be detected.
2. Narrowing of the walls of the small intestine can be diagnosed.
3. Ulceration of GI tract can be seen.
4. Physical or radiation damage to the digestive tract lining can be found out.

The element barium is an inert substance which coats the internal wall of the GI tract and thus, fills up its lumen. Since it is radio-opaque, it can be very well seen by x-rays. The services which are offered are as follows:

1. Barium swallow service : No special preparations are required for this.
2. Barium meal service : A minimum of 6 hours of fasting is required.
3. Barium meal follows service : Overnight fasting is required, coupled with laxative tablets for clearing bowel.
4. The small bowel and barium enema service : Prior to the test, a liquid diet is served to the patient, who has been fasting the night before. Strict cleaning of the bowel is also rendered by administering laxatives the night before and also in the morning.

You can go home after the test is finished, and you can eat normally right after the test.
