Classification of gastric polyps (The British Society of Gast-roenterology, 2009) Non-mucosal Intramural Epithelial Polyps Polyps Fundic gland polyp Gastrointestinal stromal tumor Hyperplastic polyp Leiomyoma Adenomatous polyp Inflamatoryfibroid polyp Hamartomatous polyp Fibromaand fibromyoma * Juvenile polyp Lipoma * Peutz-Jeghers' syndrome Ectopic pancreas * Cowden's syndrome Neurogenic and vascular Polyposis syndromes tumours (non-hamartomatous) Neuroendocrine tumours * Juvenile polyposis (carcinoids) * Familial adenomatous polyposis Table 2.
The first group is epithelial polyps, such as fundic gland polyps (FGP), hyperplastic polyps (HP), adenomatous polyps (AP), hamartomatous polyps and non-hamartomatous-polyposis syndromes.
Dysplasia development is lower than 1% in sporadic fundic gland polyps and there is no relationship between atrophic gastritis and H.

Since the early 2000s, reports especially from Western countries have been revealing sharp increase in the occurrence of fundic gland polyps [4, 7].
All visible polyps were either biopsied or removed and thus identified and studied them histologically by the pathologist and classified them as adenomatous polyps, hyper-plastic polyps, fundic gland polyps, and other polyps.
Fundic gland polyps, which were previously believed to be hamartomatous, accounted for 59.4% of all polyps in this study, which is similar to reports from other countries: 77% in a 2007-2008 nationwide US population-based study , 66.1% in a 2010 Chinese study , and 47% in a 1994 German study .
This cross-sectional study of asymptomatic individuals revealed a gastric polyp prevalence of 29.8% in Taiwan, with fundic gland polyps accounting for the largest proportion.
