The determination of how large a gastric polyp needs to be removed should be made based on the pathologic type of the polyp.
The pathologic types of gastric polyps include fundic glandular polyps, hyperplastic polyps, and adenomas.
1. Fundus glandular polyp: it occurs in the fundus of the stomach, mostly 1-5mm, which does not increase the risk of gastric cancer, and ≥1cm is recommended to be removed.
2. Hyperplastic polyp: it occurs in the gastric antrum, mostly <2cm, generally non-cancerous, but the risk of gastric cancer in other parts of the stomach is increased, >0.5cm is recommended to be resected.
3. Adenoma: it can be seen in all parts of the stomach, more common in the gastric sinus, often combined with chronic atrophic gastritis, gastric mucosal intestinal metaplasia and other pre-cancerous states, there is a risk of cancer, regardless of the size of the polyp, it is recommended to excise, and biopsy the surrounding mucosa, and it is recommended to review gastroscopy 1 year after excision.
If gastric polyps are diagnosed, early standardized treatment is recommended to reduce the adverse effects of the disease.
