In general, ultrasound gastroscopy can take the stomach tissue sent to the Department of Pathology for gastric tissue biopsy, but ultrasound gastroscopy is not equal to gastric biopsy. Ultrasound gastroscopy is an advanced set of ultrasound and endoscopy as one of the medical equipment, micro high-frequency ultrasound probe is placed in the front of the endoscope, when the endoscope into the gastric cavity, the endoscope in the endoscopy direct observation of the morphology of the gastric cavity at the same time, but also real-time ultrasound scanning, in order to obtain the pipeline wall of the various layers of the histological characteristics and the surrounding ultrasound images of the neighboring organs. Gastric biopsy is mainly performed through gastroscopy, in which biopsy forceps are inserted into the stomach through the tube inside the gastroscope, and suspected diseased tissues inside the stomach are clamped out through the biopsy forceps and sliced into sections, which are sent to the Department of Pathology, where they are stained and other means are used to learn about the type of diseased tissues and their condition, and to determine diseases such as superficial gastritis, atrophic gastritis, and gastric cancer. Gastric biopsy can be carried out by ultrasonic gastroscopy, and the comparison between the results of ultrasonic endoscopy and the results of biopsy histopathologic examination can play an auxiliary role in clinical diagnosis and treatment. However, ultrasonic gastroscopy includes not only gastric biopsy, but also endoscopic observation, so it cannot be said that ultrasonic gastroscopy is gastric biopsy.
