Examined by ultrasound, which is indications and contraindications to this procedure, which can be learned from the ultrasound of the abdominal cavity.
Ultrasound (ultrasound) of the abdominal cavity is a non-invasive study conducted with ultrasound waves. Currently, this diagnostic method is widely used not only in therapy, but also in surgery, urology, oncology, etc.
Ultrasonography of the abdominal cavity: the advantages of the method
- High informative;
- Ease of research;
- Harmless to the patient's health;
- Does not require special patient training;
The essence of the method
The basis of the ultrasound of the abdominal cavity is the principle of passing ultrasound waves, produced by the ultrasound transducer, through the organs and tissues of man.
At the same time, depending on the density and features of the structure of these tissues, the absorption or reflection of ultrasound occurs, which is captured by a special receiver (also located in the ultrasound sensor).
After that, in real time, the decoding of the received signal occurs with the formation of scanned bodies on the screen of the monitor. If necessary, you can get a snapshot of this or that body.
Surveying ultrasound of the abdominal cavity
The most widely used ultrasound is to determine the state of the liver and gall bladder, pancreas, large vessels and spleen.
Also, in the presence of special testimony, the lymph nodes, the large intestines, the stomach and duodenum available for ultrasound, the presence of free fluid in the abdominal cavity, etc. are studied.
What information can be obtained from the ultrasound of the abdominal cavity
When conducting an ultrasound physician examines the shape, size, position and structure of the abdominal cavity, as well as some of their functionality. For example, to clarify the condition of the contractile function of the gallbladder, conduct research, pre-stimulating the work of the bubble with a choleraic breakfast.
In addition, in the presence of indications, the doctor:
- Conducts studies of blood flow in large organs and their structures (in the liver, spleen, etc.);
- Determines the presence (or absence) of abnormalities in the development of organs and tissues, postoperative changes (if performed operations), traumatic injuries, extraneous bodies, etc.;
- Detects changes that are characteristic of various diseases, benign and malignant tumors.
Also, ultrasound of the abdominal cavity is sent:
- In the period of preparation for planned surgical interventions;
- For control after operations;
- For evaluation and necessary correction of treatment;
- Women planning pregnancy;
- Persons engaged in extreme sports;
- For the assessment of the health status of persons engaged in harmful production (working at chemical plants, etc.);
- Arranged to work with increased requirements for health (work in law enforcement agencies, MOE, etc.).
For ultrasound examination of the abdominal cavity there are no absolute contraindications. But it is still believed that it is necessary to limit the number of surveys conducted and their duration with:
- Retinal detachment (or threat of this condition);
- Normally pregnancy occurs (it is recommended to do it only at certain times).
Ultrasonography of the abdominal cavity is usually performed on an empty stomach. The patient is recommended to eat at least 7-10 hours prior to the study. When ultrasound is allowed in the afternoon, a light morning breakfast is allowed (especially important for diabetics).
It is advisable to consult your doctor or ultrasound doctor about taking regular medicines and the expediency of their cancellation on the day of the study.
With pronounced propensity to flatulence (gas formation, abdominal distension) 2-3 days before ultrasound is not recommended to eat beans, fresh vegetable food, dairy products and black bread. When eating it is advisable to take enzymes (mesim, festal, etc.), and between meals 3-4 times a day - 2-3 tablets of activated charcoal.
