EUS — in a short abbreviation, the encrypted words endoscopic ultrasonography. This is a high-tech method of examining organs of the gastrointestinal tract. Its uniqueness is that it includes two types of diagnostics at once — endoscopy and ultrasound examination.
Patients are examined using a special device called an echo-endoscope. The peculiarity of the device is the combination of a traditional endoscope with an ultrasonic sensor located on its end. Know that, in addition to the term "endoscopic ultrasonography (EUS)", you can also find synonyms: endosonography, echoendoscopy, endoscopic ultrasound, Endo-UZD.
It is important to understand that EUS — not a screening method. Such a study is carried out after computer tomography or PET-CT, or gastroscopy, if these methods still did not give the doctors an exact answer about the spread of the tumor. And then it is the result of endoscopic ultrasonography that will allow doctors to perform a preoperative assessment of the tumor, which will finally determine how to properly conduct the treatment, that is, it will allow to develop optimal treatment tactics.
And this means that in some cases — depending on how far the tumor has spread throughout the body, whether the adjacent lymph nodes have been touched or not — the patient can avoid surgery.
Just like in the world's leading clinics, we use endosonography to determine the stage of malignant diseases of the digestive tract, assess submucosal formations of the stomach and esophagus, and diagnose thickened gastric folds.
EUS makes it possible to obtain a detailed image of pathological changes, any deviations from the norm, thanks to the location of the ultrasound sensor close to the organs — stomach, duodenum, esophagus.
More about the indications for EUS
Endoscopic ultrasonography is performed for:
- detection of local spread of tumors of the gastrointestinal tract and metastases in the lymph nodes;
- diagnosis of non-epithelial formations, i.e. there are. determining from which layer education originates, — depending on the size, treatment or dynamic supervision is carried out;
- clarification of the causes of the formation of thickened gastric folds: lymphoproliferative diseases, infectious diseases, Menetriere's disease, malignant tumors, metastatic lesions.
However, there are limitations to the implementation of EUS. They include:
- diseases of the esophagus and proximal parts of the stomach, the stenosis of which does not allow the introduction of an echo-endoscope into the stomach or duodenum;
- gross cicatricial-ulcerative and postoperative deformations of the bulb of the duodenum, which do not allow the correct placement of the ultrasound probe to evaluate the structures of the liver and biliary tract;
- state after gastric resection or gastrectomy (stomach removal).
Regarding the preparation for the examination, it does not differ from the preparation for a regular gastroscopy. That is, the procedure is performed on an empty stomach: you cannot eat food for 6-8 hours before the study, and liquid — 4 hours before the study. You will get additional information from your doctor.
And know — it doesn't hurt! You will simply sleep during the research.
The examination is performed only in a state of medicated sleep, and the entire procedure is accompanied by an experienced anesthesiologist.
