Different types of gastric polyps are treated differently: 1, hyperplastic polyps: this type of polyps account for about 75% to 90% of gastric polyps, which are polyps formed by inflammatory mucosal hyperplasia, not real tumors. The polyps are small, generally less than 1,5cm in diameter, round or olive-shaped, with or without a tip, smooth surface, and can be accompanied by erosion. The epithelium is well differentiated and nuclear schizophrenia is rare. Inflammatory cell infiltration is seen in the lamina propria, and some polyps are accompanied by intestinal metaplasia. A small number of hyperplastic polyps can undergo heterogeneous hyperplasia or adenomatous transformation and produce malignant changes, but their cancer rate is generally not more than 1% to 2%. 2, adenomatous polyps: benign gastric tumors derived from the epithelium of the gastric mucosa, accounting for about 10%-25% of gastric polyps. Generally large, spherical or hemispherical, mostly non-tip, smooth surface, a few flattened, striped or lobulated. Histologically, they are mainly formed by surface epithelium, small concave epithelium and glandular hyperplasia. The epithelial differentiation is immature and nuclear schizophrenia is common, which can be divided into tubular, villous and mixed adenomas, often accompanied by obvious intestinal hyperplasia and heterogeneous hyperplasia. The interstitium of the polyp was loose connective tissue with a small amount of lymphocytic infiltration. There was no obvious hyperplasia in the mucosal muscle layer and no dispersion of muscle fibers. The cancer rate of this type of polyp is high, up to 30%~58.3%, especially the malignant rate is higher for those with tumor diameter greater than 2cm, villous adenoma and heterogeneous hyperplasia degree III. Diagnosis: Gastric polyps often have no clinical symptoms and are difficult to diagnose, most of them are detected by X-ray barium gastric fluoroscopy and gastroscopy. When inflammation occurs in gastric polyps, there are gastritis-like symptoms, such as pain in the upper abdomen, fullness, nausea, belching, loss of appetite, heartburn and diarrhea. When the polyp occurs in the cardia, there is a feeling of swallowing obstruction. When it occurs in the pyloric duct, it is easy to have pyloric obstruction or incomplete obstruction, and the abdominal pain and bloating is aggravated with vomiting. Black stool and vomiting of blood may occur when the polyp is ulcerated or cancerous. Gastric polyps rarely have positive signs, but when combined with inflammation, there may be pressure pain in the epigastrium, and secondary anemia may appear if there is a lot of bleeding.
