What Is a Barium Meal?
Barium meal angiography, or barium angiography of the digestive tract, refers to the use of barium sulfate as a contrast agent to show the presence or absence of lesions in the digestive tract under X-ray irradiation. Unlike barium enema, barium meal angiography is to take contrast agent by oral route, which can make a clearer radiological examination of the entire digestive tract, especially the upper digestive tract. The barium meal used for gastrointestinal examination is medicinal barium sulfate (a suspension of barium sulfate), because it is insoluble in water and lipids, it will not be absorbed by the gastrointestinal tract mucosa, so it is basically non-toxic to humans.

Barium meal for digestive tract examination is medicinal
- Insoluble in water and insoluble in acid. The solubility in water is only 0.0024g / 100g water. Soluble in heat
- Used as white pigment, paper and rubber, etc.
- During X-ray examination, due to the density and thickness of various organs and tissues of the human body, a natural contrast of black and white is displayed. However, in some parts of the human body, especially the abdomen, because the density of several internal organs and tissues is generally similar, it is necessary to introduce a contrast agent that is not harmful to the human body. For elements such as barium and iodine, the atomic coefficient is large, which interacts with xray. The photoelectric effect will radiate characteristic X-rays that can pass through human tissues and reach the film to form a fog, and artificially increase the display contrast to achieve the ideal inspection effect. This test method is clinically called X-ray barium meal
- X-ray angiography is more commonly used for barium meal and barium enema. The test is safe, non-invasive, and has no side effects, but some patients, such as patients with acute respiratory infections, patients with severe heart, liver, and kidney dysfunction, and iodine tests
- 1. Observe esophagus, stomach, duodenum congenital malformation, chronic inflammation, foreign body, tumor and understand its functional status.
- 2. To understanding
- 1. Perforated esophagus, gastrointestinal tract, or
- Barium swallowing or barium enema examination can only see the outline of the digestive tract, and barium-filled gastrointestinal angiography often covers tiny lesions. Therefore, oral foaming agents or gas injection into the intestine are often used to make the gastrointestinal tract high. Density barium agents, and low density air shadows, form air-barium contrast contrast, which is easy to obtain positive results.
- According to the needs of clinical diagnosis and treatment, gastrointestinal barium meal can be divided into upper gastrointestinal barium meal, total gastrointestinal barium meal,
- In medicine, if a soluble barium salt such as barium chloride is used as barium sulfate, a soluble sulfate such as magnesium sulfate is usually used for detoxification. Barium ions are heavy metal ions and are very harmful to the human body. Introduce
- 1. Drugs containing metals (such as calcium tablets) are banned from the day before the test.
- 2. The general examination takes several hours. Please be patient and don't eat anything without leaving the doctor. A few patients had to be re-examined that afternoon.
- 3. It is best to wear underwear without buttons when checking.
- 4. Barium sulfate angiography is strictly prohibited when clinically suspected or diagnosed with intestinal obstruction.
- 5. The day before the inspection, the diet should be mainly semi-liquid, and it is not advisable to eat after 10 pm.
- 6. White feces may be discharged after inspection, which is normal. After inspection, drink plenty of water so that barium meal can be discharged as soon as possible.
- Patients are generally free of pain and other complications during barium meal examinations and are easy to accept. The patient first took a single injection (20ml of bupropion scopolamine injection), and then took 3-5 grams of gas-producing powder orally (dry throat) to fully expand the stomach. Standing on the examination table, according to the doctor's requirements, make corresponding physical movements and swallow a large mouth of medical pure barium sulfate suspension, the total amount is about one paper cup. When the X-rays pass through the human body, the shape, size, position, and peristalsis of the stomach filled with barium are indirectly observed by the display, and the camera is used to make a comprehensive judgment based on clinical manifestations. For some patients with atypical clinical symptoms and X-ray signs, other tests must be combined.
- 1. Abnormal results: The focus of X-ray barium meal examination is to find abnormalities and confirm the lesions. X-ray diagnosis of gastric cancer must be based on the X-ray manifestation of the tumor itself and its surrounding changes, synthesize all X-ray signs, and combine clinical data and other examinations to reach the correct conclusion.
- 2. The double contrast method of the stomach can clearly show the microstructure of the gastric mucosa surface, such as the gastric area, and is very valuable for the diagnosis of early gastric cancer and microlesions.
- 3. The double contrast angiography method can show the subtle changes of the mucosal surface, which is of great value in the diagnosis of early gastric cancer. The lesions above 2cm are easy to find, and the fine X-ray examination mainly based on the double contrast angiography method can detect less than 1cm. Small gastric cancer, even tiny gastric cancer within 5mm.
- 4. People who need to be checked: those who have frequent pain in the stomach and intestines. [1]
- The cost of treatment is about 450 yuan to 800 yuan, depending on the medication and equipment used, this is just a reference fee. Some even said that it only cost tens of yuan.
