Endosonography of the stomach: indications, preparation, conduct and results
Endosonography is a modern diagnostic procedure that combines two methods of screening, such as ultrasound and endoscopy. This method of diagnostics allows to assess the condition of the gastrointestinal tract, including the esophagus, gallbladder and bile ducts, pancreas, etc. However, very often this method is used to detect diseases of the stomach. Endosonography is used after consultation with the attending physician if there are indications to its implementation.
The combination of ultrasound with endoscopy allows to achieve high results in detecting cancer and inflammatory diseases of the stomach.
Method of diagnosis that combines endoscopy and ultrasonography, can be used in the following situations:
- The identification of tumor formation in the stomach wall, the pancreas and biliary ducts.
- The possibility of differential diagnosis of non-epithelial neoplastic processes in the stomach.
- A biopsy revealed suspicious entities.
- Estimating the prevalence of inflammatory processes in the wall of the body.
- Identification of the cystic formations.
- Assessment of degree of disorders of blood flow in the blood stream of the organ and the detection of ischemia, etc.
Use the endosonography is necessary only after consulting your doctor.
In each case, the attending physician decides to use this procedure or to refuse it. A key factor in the purpose of this method is the absence of contraindications to its use. To last include:
- Cardiac arrhythmias and ischemic myocardial damage in the acute phase.
- Heart failure third degree.
- Suspected hemophilia or diagnosis.
- The presence of strictures or narrowing of the esophagus.
- Acute tonsillitis, pharyngitis and bronchitis.
- An increase in intraocular pressure.
- Epileptic and mental illness, however, it is possible to conduct research on the background of anesthesia.
Contraindications it is necessary to abandon such research or to select its analogs, allowed in such situations.
The preparations of endosonography, particularly
There are some simple guidelines that will help to prepare your body for the study and to provide the best results:
- 6-8 hours before the test you must refuse to accept food and liquids. This will help to empty the stomach and to improve the quality of the image.
- Should be familiar with the course of the procedure and discuss it with his doctor to reduce stress levels and understanding further medical procedures.
As a rule, use special methods of preparation (diet, cleansing enema formulation, etc.) in the study of the stomach is not required.
The conduct of endosonography, particularly
The study of the esophagus, stomach, pancreas, and other organs of the upper digestive system is done using a small endoscope with a source of ultrasound. The method resembles the routine fibroezofagogastroduodenoscopy. The patient without the use of anesthesia is administered through the mouth with a special endoscope into the esophagus and stomach. Sometimes your doctor may use a local anesthetic to reduce the gag reflex in some patients.
Endosonography may cause the development of a number of complications (bleeding, damage to the stomach wall), therefore you must carefully monitor the patient’s condition during and after the procedure.
Exploring the wall of the stomach, the doctor can identify tumors and inflammation of education in it, to detect cystic cavity. If necessary, possible biopsy for further diagnosis. Fine-needle aspirator when it is introduced through the endoscope.
The method has a good tolerance in patients and is associated with a low risk of side effects, that causes its widespread use for the diagnosis of diseases of the gastrointestinal tract, including bile ducts and pancreas.
After the procedure
Immediately after the examination the patient is placed in hospital for observation for several hours. Usually the only discomfort from the procedure associated with bloating and mild discomfort along the esophagus.
All patients should be encouraged:
- Provide yourself sufficient rest after you return home.
- 1-2 hours after the procedure you can eat and drink water.
- If procedures were used sedatives, it is necessary to abandon independent travel by car and also from the work associated with decision-making or fine motor skills.
- You must comply with all instructions of the attending physician.
Subject to these rules the risk of developing long-term complications of endosonography, particularly of the stomach is reduced to a minimum.
Possible complications of the procedure
Features of the patient or failure to observe study can lead to complications of the procedure:
- The most frequent complication is infection of the stomach or esophagus with the development of gastritis or esophagitis, respectively. You may also receive aspiration lesions of bronchopulmonary system.
- Broken technique the procedure can cause intraventricular hemorrhage or perforation of the organ.
- Possible reactive changes in the organs of the gastrointestinal tract (pancreas, liver, etc.) in the form of pancreatitis, hepatitis, etc.
- A number of patients with an undiagnosed contraindications may cause arrhythmias, myocardial infarction, high blood pressure, etc.
Observance of technology of endosonography, particularly and careful collection of patient history, external examination, reduce the risk of complications. This procedure has a high degree of safety and good tolerability in patients of different age groups.
Endosonography of the stomach is a modern and highly informative method of examination of the upper digestive system that can identify cancer and inflammatory diseases in the early stages of their development. Before the study, all patients are encouraged to pre-consult with your doctor or gastroenterologist.
