Atrophic gastritis without biopsy usually can not be fully judged, the accuracy will be higher after biopsy. Atrophic gastritis in gastroscopy if you can see the color of the gastric mucosa becomes pale, submucosal blood vessels see through, the surface is rough and uneven, atrophic mucosal brittleness increases, easy to bleed, and there can be erosion foci, etc., can be roughly judged to be atrophic gastritis, and its accuracy is not absolute, at this time in order to further clarify the diagnosis, usually take the lesion part of the biopsy, to consolidate the results of the diagnosis. For the diagnostic criteria of atrophic gastritis only according to the symptoms, signs can not be used as the basis for the final diagnosis, the symptoms and signs are not specific, the diagnosis mainly depends on gastroscopy and gastric mucosal biopsy to confirm the diagnosis of the histopathological biopsy as the gold index. Histopathological biopsy combined with endoscopy is the main method of examining chronic gastritis, which can be assessed as non-atrophic gastritis and atrophic gastritis, and at the same time can assess the degree of atrophy, intestinal metaplasia, and the presence or absence of intraepithelial neoplasia and its degree. Therefore, when stomach pain, nausea and vomiting occur, it is recommended to go to the hospital in time, and diagnose the disease after the doctor prescribes the corresponding auxiliary examination results back.
