Gastric polyps and polypoid lesions: Retrospective analysis of 36650 endoscopic procedures in 29940 patients

Abstract: Background/Aims: The frequency of gastric polyps increases with the widespread use of endoscopy for diagnosis and treatment. As gastric polyps can be malignant or premalignant, histopathological evaluation is needed. The aim of this study is to determine the prevalence and characteristics of gastric polyps in patients undergoing endoscopy. Materials and Methods: This study consisted of a retrospective analysis of 36650 consecutive endoscopy and associated pathology reports of 29940 patients between December 20… Show more

“…Recent epidemiologic evidence suggests that the incidence of g-NENs is between 0.3% to 1.8% of all gastric tumors [20,21]. Studies from national histopathology or endoscopy database have shown that the prevalence of g-NENs ranks in the top 5 among the gastric polypoid lesions, and about 3.3% of gastric polypoid lesions are neuroendocrine tumors (NETs) [22,23]. Therefore, it is important to enhance the understanding of g-NENs.…”

“…It has been found patients taking PPI for less than 1 year will not develop FGP [29] ; however, long-term PPI therapy increases the risk of polyps (in particular, it is associated with a 4-fold increased risk for FGP) [30] . This phenomenon is considered to be a cystic change caused by the chronic stimulation of gastric mucosa by a high level of gastrin [31] . Animal experiments have revealed that gastrin can promote the growth of parietal cells by increasing their height and size [32] .…”
