Gastric polyps are important as some have malignant potential. If such polyps are left untreated, gastric cancer may result. The malignant potential depends on the histological type of the polyp. The literature base is relatively weak and any recommendations made must be viewed in light of this.
Gastric polyps are sessile or pedunculated lesions that originate in the gastric epithelium or submucosa and protrude into the stomach lumen.
Depending on histological type, some gastric polyps (adenomas and hyperplastic polyps) have malignant potential and are precursors of early gastric cancer. They may also indicate an increased risk of intestinal or extra-intestinal malignancy.
胃息肉很重要，因为有些胃息肉有恶性潜能。如果这些息肉得不到治疗，可能会导致胃癌。恶性潜能取决于息肉的组织学类型。文献基础相对较弱，因此必须根据这一点来看待任何建议。
胃息肉是指起源于胃上皮或黏膜下层并向胃腔突出的无蒂或有蒂病变。
根据组织学类型，一些胃息肉（腺瘤和增生性息肉）具有恶性潜能，是早期胃癌的前体。它们也可能表明肠道或肠道外恶性肿瘤的风险增加。
