Fluoroscopy of esophagus and stomach in the Trendelenburg position
X-ray examination in diseases of the gastrointestinal tract to diagnose the disease early — when treatment brings the maximum effect. X-rays of the esophagus and stomach is the most simple and informative manner to establish an accurate diagnosis. Using this method diagnosed functional disorders, diseases such as gastric ulcer, found neoplastic processes.
Despite the fact that the stomach is a hollow body, density of its walls identical to the density of other organs peritoneum cavity, at a standard x-ray, it will be virtually indistinguishable. Therefore, it is necessary a preliminary contrast – filling of the stomach radiopaque substance. Standard x-ray is a less accurate method as it involves only the static images.
Preparation for fluoroscopy
In order to do research correctly, you need little preparation of the patient. Fluoroscopy is performed on an empty stomach, so the last meal is allowed a minimum of seven hours prior to the procedure. Prohibits not only food, can’t drink, take drugs and smoke.
Important! At the stage of preparing for the procedure, the attending physician must notify the manifestations of Allergy, even if the reaction was noted long ago and was not intensity. Any jewelry from the body must be removed before the study.
All patients with severe disorders of digestion, and the elderly, for 2-3 days before x-rays requires a special diet, which completely excludes
- carbonated beverages;
- overly sweet foods;
- milk and dairy products.
These days diet should contain cereals porridge on the water, lean meat and allowed fish, eggs. You need to remember that failure to comply with rules of training can lead to the fact that the results are incorrect. Fluoroscopy is not x-ray, repeat the procedure is extremely undesirable because the radiation dose will be too high. A liquid with barium, the patient is already taking at a time when he is behind the screen x-ray machine. If necessary, research of the colon, contrast is injected through an enema.
After preparing the patient for the study, he drinks the barium, the amount of which the standard procedure is 250 ml. Gradually into the gastrointestinal tract, the contrast gives the radiologist the opportunity to explore the state of the mucous membranes, to identify the defects according to the degree of occupancy by contrast, to know the time required for the onset of phase absolute content.
Field that comes the phase of «hard» content. At this time, the doctor receives the following information:
- the size of the stomach;
- the location of all the digestive organs;
- the removability of the structure;
- extensibility and contractility.
Here you can determine the specific location of the ulcer or neoplasm. In that case, if there is suspicion of a tumor will require additional study, because radiographic methods do not allow to determine the type of tumor is benign or malignant. Standard x-rays may not reveal some pathology.
For more information can be assigned x-ray of the esophagus and stomach in the Trendelenburg position. The patient fixes the pelvis elevated at 45 degrees condition – this posture allows you to clearly diagnose the hernia hiatal. In addition, the doctor often asks the person to lie sideways, or take a different position, depending on the characteristics of the intended disease.
Immediately before the x-rays consultations with specialists:
- the gastroenterologist.
If necessary, in the preliminary survey involves and doctors of other specialties.
Double contrast in the study of the stomach and intestines
The gastrointestinal tract may suffer from a variety of pathologies, and standard fluoroscopy methods may not always give the full picture. In some cases, the doctor may see the need for fluoroscopy with double contrast. It is the same suspension of barium, but the patient should drink it through a special perforated tube that supplies the air into the stomach.
Massaging anterior abdominal wall contributes to a better distribution of barium in the stomach wall, and trapped air in it ensures the straightening of the folds. If it is necessary to study the colon, a contrast agent, it is administered by enema. Before the study requires special training. The purpose of the diet under fluoroscopy of the large intestine is also desirable, as in the investigation of other departments of the gastrointestinal tract.
Advantages over other types of diagnostics
The merits of this method of research, as x-rays a lot, and among them are the following:
- the speed of obtaining results, the doctor sees a picture of what is happening in real time, to confirm what he saw, other methods is almost not required;
- painless research that does not require the use of anesthesia is important for elderly patients;
- affordable cost and easy – equipment for fluoroscopy are installed in every municipal clinic;
- the minimum number of restrictions, excellent portability and easy preparation for the study, which is available to everyone, regardless of age and financial situation.
The effects of x-rays
Any kind of x-ray examination is quite safe and does not cause adverse effects, including those associated with ionizing radiation. This is due to strict accounting of all exposures, unless absolutely necessary person is not subjected to further study such methods. Contrast x-ray, for some patients, becomes a cause of dyspepsia:
- moderate pain in the epigastrium;
- nausea and heaviness in the stomach;
- violations of the chair – predominant constipation.
In that case, if the symptoms persists more than three days should seek medical assistance. Such symptoms are associated with barium – it often leads to constipation and light digestive disorders. To accelerate excretion of the substance after the procedure you can drink 1.5-2 liters of clean water, or take a mild laxative. Other events do not hold.
