Abstract

Gastric polyps are lesions projected above the mucosal surface, which are detected in approximately 1–6% of upper gastrointestinal endoscopies. Based to their shape, polyps are classified as pedunculate, semi-pedunculate, sessile and flat. Depending on the histopathological type, some of them have the potential to transform into adenocarcinoma. Polyps can be of epithelial and non-epithelial origin. The first group, which is discussed in greater detail in this paper, includes fundic gland polyps, hyperplastic, adenomatous and hamartomatous polyps. Non-epithelial polyps include stromal tumours, leiomyomas, fibrous inflammatory polyps, fibroids, fibromyomas, lipomas, ectopic pancreas, neuroendocrine tumours, neuromas, and some vascular lesions. Multiple polyps in patients under the age of 40 years require more extensive diagnosis for hereditary polyposis syndromes, which are associated with an increased risk of gastric cancer, as well as other gastrointestinal and extra-gastrointestinal malignancies. In recent years, there has been a clear decrease in the proportion of hyperplastic polyps and an increase in the proportion of fundic gland polyps among all gastric polyps, which is probably related to the increased use of proton pump inhibitors and a reduced incidence of Helicobacter pylori infections. About 90% of gastric polyps are detected accidentally and usually do not cause clinical symptoms, but large polyps may be responsible for anaemia, bloody stools, abdominal pain, and even pyloric obstruction, which may be manifested by vomiting, severe flatulence, lack of appetite or progressive weight loss.
