Gastric polyps (GPs) are found in 1-6.4% of upper endoscopies. The epidemiology of GPs is linked to the prevalence of Helicobacter pylori (HP), as its presence may be a risk or protective factor for certain types of polyps. Most of the time, GPs are asymptomatic and randomly found. However, they can sometimes cause chronic anemia, acute digestive bleeding, abdominal pain, or upper digestive obstruction. As it is difficult to distinguish between the different types of GPs, it is important to examine them in white light and virtual chromoendoscopy. It is also essential to examine the surrounding gastric mucosa with the above-mentioned technique to assess the presence of gastric atrophy or intestinal metaplasia. Epithelial polyps are the most common and include fundic gland polyps (77% of GPs, sporadic or in familial adenomatous polyposis), hyperplastic polyps (17%), adenomas, neuroendocrine tumors, and ectopic pancreas. Hamartomatous polyps are mucosal polyps that can derive from the three embryonic layers. They have the same endoscopic characteristics as hyperplastic polyps. They are found in Peutz-Jeghers syndrome, juvenile polyposis, and Cowden syndrome. In this article, the different types of GPs will be described, with their epidemiology, risk factors, endoscopic characteristics, therapeutic management, and recommended surveillance.
