Doctors have long and successfully learned to recognize and treat conditions of the digestive system, but today more and more advanced technologies are being used. One of the most effective methods for diagnosing diseases of the gastrointestinal tract is endoscopic ultrasound.
What is endoscopic ultrasound?
Now for the study of the abdominal cavity and pelvic organs, one of the traditional methods of diagnosis is most often used: transabdominal ultrasound, which is carried out through the anterior abdominal wall. Endoscopic ultrasound is a hybrid technology - the connection between ultrasound and endoscopy. If in routine ultrasound, recognition is performed through the skin, endoscopy is accomplished by inserting into the esophagus a particular ultrasound endoscope directed to the organ to be examined.
In what cases is endosurgery used
Ultrasound-endoscopes are of two types: radial and linear (convective). Redial allows you to obtain a detailed image of the walls of hollow organs and adjacent structures and using a direct echoendoscope you can perform a fine needle aspiration (sucking) biopsy. The primary indication for the use of endoscopic ultrasound is the staging of tumorous diseases of the organs of the upper digestive tract (esophagus, stomach, and duodenum). During the study, the depth of tumor invasion into the organ wall is determined, the regional lymph nodes and distant metastases are assessed.
The use of echo endoscopes also makes it possible to perform diagnostics of submucosal formations of the upper digestive tract, to determine the benign or malignant structure, to reveal the layer from which it originates. All this is fundamentally important for determining the further tactics of treatment. Even small pancreatic cysts can be successfully drained under the control of endoscopy, which allows choosing the most successful point for puncture, where there are no significant vessels, and there is the most intimate contact of the wall of the cyst with the wall of the organ.
Also, endoscopy helps diagnose diseases of the pancreatobiliary zone, detect tumor lesions of the pancreas, sizeable duodenal papilla, and bile ducts. With the help of an echoendoscope, it is possible not only to determine the nature of cystic and other pancreatic neoplasias but also to perform a fine needle aspiration biopsy for morphological examination and confirmation of the diagnosis.
Preparation for endoscopic ultrasound
As with the preparation for the regular endoscopic examination of the upper gastrointestinal tract, it is necessary to observe the fasting regime: you cannot eat or drink for 12 hours. But unlike ordinary gastroscopy, the vast majority of endoscopy is performed under general anesthesia. Firstly, the study is quite long: depending on the indications it takes from 20 minutes to 1 hour.
Secondly, the echoendoscope is more rigid and of larger diameter, which causes unpleasant sensations to the patient. Diagnostic endoscopic ultrasound test cost in Noida and other cities is performed in outpatient settings, and fine needle aspiration biopsy and therapeutic interventions are performed in a hospital. The patient regains consciousness right after the end of the procedure, and full recovery is needed from half an hour to an hour.
