Ultrasound endoscopy is much more strenuous than regular gastroscopy, and it is still up to the patient to decide whether anesthesia is needed. It also depends on whether the hospital has enough anesthesiologists in reserve. Because some hospitals have a very shortage of anesthesiologists, they cannot send enough anesthesiologists to meet the anesthesia arrangement for each patient in the clinic. If it goes well, ultrasound gastroscopy can be completed in 5 or 10 minutes. It is more strenuous than regular gastroscopy, but most patients can tolerate it. Special preparation is actually required prior to performing ultrasound gastroscopy. Patients must have a general gastroscopy, a transabdominal ultrasound, and a CT exam before deciding to have an ultrasound gastroscopy. This is because the main indication for ultrasound gastroscopy is gastrointestinal augmentation lesions. The stomach wall can be divided into five layers, and different layers have different sources of disease. It is important to distinguish the levels where the gastrointestinal augmentation lesions originate, which is crucial for the diagnosis and treatment of patients. Ultrasound gastroscopy is a relatively rigid ultrasound probe added to the front of the gastroscope, and with the probe in place, the view of the mirror is not an anterior view mirror, but often an oblique or lateral view mirror. If the ultrasound gastroscope is used to do a general gastroscopy screening there will be limitations and some lesions will be missed. Therefore, the general procedure is to do a general gastroscopy to find lesions first and then apply for an ultrasound gastroscopy. The doctor doing the ultrasound gastroscopy has to take the report image of the general gastroscopy and do the ultrasound directly to the location of the lesion when doing the ultrasound, which can effectively reduce the time of the examination and the pain of the patient.
