Core Tip
Core tip: Recent studies have suggested that fundic gland polyps (FGPs) are the dominant type of gastric polyps rather than hyperplasic polyps. In the Chinese population, data on the spectrum of gastric polyps are limited, and the dynamic change in polyp spectrum has never been evaluated on a large scale. Hence, we retrospectively reviewed 4043 cases with gastric polyps from 157902 patients who underwent esophagogastroduodenoscopy in a tertiary hospital over a 10-year period. We observed a dynamic change in the spectrum of gastric polyps, which presented as a shift in which FGPs rather than hyperplastic polyps were the most common type, and the age, location and sex distribution of gastric polyps were also altered.
