Electronic ultrasound gastroscopy vs. ultrasound gastroscopy, are they the same? Answer

Electronic Ultrasound Gastroscopy (EUS for short) is an advanced medical device that combines ultrasound and endoscopy. It places a miniature high-frequency ultrasound probe at the front end of the endoscope, and when the endoscope enters the gastric lumen, real-time ultrasound scanning can be performed at the same time as the endoscope observes the morphology of the lumen directly in order to obtain the histological characteristics of the pipe wall at all levels and the ultrasound images of the surrounding neighboring organs.

The main advantages of EUS are to determine the nature of gastrointestinal submucosal lesions, to determine the depth and extent of invasion of malignant tumors in the digestive tract, and to diagnose diseases of the pancreatic system. Ultrasound endoscopy differs from ordinary gastroscopy in that ultrasound endoscopy has an additional ultrasound probe at the front end, and this small probe is sent with the gastroscope into the gastric lumen for ultrasound detection, which allows for visualization of lesions in the deeper layers of the esophagus and stomach. Therefore, ultrasound endoscopy has good diagnostic and therapeutic value for augmented lesions of the esophagus and stomach. In addition I do not know whether the ultrasound gastroscopy you are talking about is the Doppler gastrointestinal ultrasonography that has been popularized at present, which is a kind of b ultrasonography and has much poorer diagnostic value than the former.
