Most gastrointestinal diseases have a latent period in the early stage, which is not easily detected. Gastric polyps are a typical example. The common symptoms include abdominal distension or dull pain, and its harm is also very great. So, how to diagnose gastric polyps?
Gastric polyps usually have no obvious symptoms in clinical manifestations, and they only appear when complications occur, such as discomfort in the upper abdomen, nausea, vomiting, or upper gastrointestinal bleeding. Polyps with pedicles in the pyloric region may cause intermittent pyloric obstruction, and the symptoms can be relieved after changing body position. Gastric polyps are often accompanied by chronic gastritis, so there may be corresponding symptoms.
Experts introduce that the diagnosis of gastric polyps mainly depends on gastroscopy and upper gastrointestinal X-ray barium meal radiography examination. Radiography examination can detect larger polyps, which are manifested as protruding lesions in the stomach cavity. Under the gastroscope, polyps are mostly round or semi-spherical, and some are lobulated. The surface mucosa is smooth or has fine granular sensation, mostly orange-red, slightly darker than the surrounding mucosa; the changes at the top of long-pedicle polyps are more obvious, which may have white moss, erosion or bleeding.
If there is erosion necrosis on the surface of the polyp observed under the microscope, infiltrative lesions at the base, uneven granules on the surface, nodular polyps, etc., there may be the possibility of malignancy. Biopsy should be routinely performed for all polyps seen under endoscopy, and multiple samples should be taken from different places. However, endoscopic biopsy has great limitations and is prone to miss early malignancy. Therefore, it is advisable to perform continuous slicing and full tumor biopsy after removing the polyps under endoscopy.
