Endoscopic ultrasonography is a relatively new endoscopic method of examination to determine the invasion of tumors of the gastrointestinal tract, detection and sizing of pancreatic tumors, diagnosis of chronic pancreatitis, pathology of the biliary tract. The method combines the possibilities of two studies: endoscopic and ultrasound. The study is performed using a video endoscope, at the end of which is a scanning ultrasound sensor. The advantages of endoscopic ultrasound over traditional ultrasound examination through the anterior abdominal wall are that the ultrasound sensor under visual control through the lumen of the digestive tract can be carried out directly to the investigated object. The use of very high frequencies of ultrasound provides high image quality with a resolution of less than 1 mm, inaccessible to other research methods (ultrasound, computer tomography and magnetic resonance imaging, endoscopic cholangiopancreatography).
