What are adenorumenal polyps?

The stomach is a particularly important organ in the human body. Both eating and digestion pass through the stomach, so everyone should have a healthy stomach. However, the stomach is also relatively fragile. If you do not pay attention to care in your daily life, it is easy to induce some stomach diseases, such as gastric polyps, which are particularly common. Today I would like to introduce to you what adenomatous gastric polyps are. What are the symptoms of adenomatous gastric polyps?

1. Hyperplastic polyps

This type of polyp accounts for about 75% to 90% of gastric polyps. It is a polyp-like substance formed by inflammatory mucosal hyperplasia and is not a true tumor. The polyps are small, generally less than 1.5 cm in diameter, round or olive-shaped, with or without pedicles, smooth surface, and may be accompanied by erosion. Histologically, hyperplasia of gastric foveolar epithelium and hyperplasia of lamina propria glands can be seen. The epithelium is well differentiated, nuclear division figures are rare, inflammatory cell infiltration is seen in the lamina propria, and some polyps are accompanied by intestinal metaplasia. A small number of hyperplastic polyps may undergo dysplasia or adenomatous transformation and become malignant, but the canceration rate generally does not exceed 1% to 2%.

2. Adenomatous polyps

It is a benign gastric tumor originating from the gastric mucosal epithelium, accounting for about 10% to 25% of gastric polyps. They are generally large in size, spherical or hemispherical in shape, most are sessile, with a smooth surface, and a few are flat, strip-shaped or lobed. Histologically, it is mainly composed of surface epithelium, foveal epithelium and glandular hyperplasia. The epithelial differentiation is immature, and nuclear division is common. It can be divided into tubular, villous and mixed adenomas, often accompanied by obvious intestinal metaplasia and dysplasia. The polyp stroma is loose connective tissue with a small amount of lymphocyte infiltration. There was no obvious proliferation of the muscularis mucosa and no dispersion of muscle fibers. The canceration rate of this type of polyp is high, reaching 30% to 58.3%, especially those with a tumor diameter greater than 2 cm, villous adenoma, and grade III dysplasia.

It can be seen that there are many causes of rumen polyps, most of which are benign, but if they are not treated in time in the early stages of the disease, the condition will worsen. What is adenomatous gastric polyp? I hope the above introduction can attract your attention. Everyone must pay attention to the care of stomach health, develop regular eating and living habits, and avoid overeating.
