“…According to literature, the vast majority of fundic gland polyps occur in patients who are not infected with H. pylori [19,20] . In addition, long-term duodenal re ux can cause chronic in ammation, gastric pit cell hyperplasia, atypical hyperplasia, polyps, and other lesions [21,22] . Large amounts of gastric re ux can cause in ammatory changes in the mucosa [23] ; also, it can alter the acid-base balance in the stomach, leading to excessive secretion of gastrin, which, to a certain extent, promotes cell proliferation and thus triggers the forming of hyperplastic polyps [24,25] .…”

Background:According to the study population, incidence of gastric polyps (GPs) varies from 0.33% to 6.7% in various studies. Most GPs consist of hyperplastic polyps (HPs), fundic gland polyps (FGPs), and adenomatous polyps (APs). Despite the high malignant APs potential, sporadic FGPs has no malignant potential. On the contrary, HPs has a lower risk of potential harm. It is not sufficient to perform biopsies to determine the presence of polyp types and displacements, therefore, some polyps may require extensive biopsy or complete resection. MethodsThis retrospective study included GPs patients or polyphenic lesions with polyps or malignant histology found in polyps or gastroscopy at the Department of Gastroenterology, Shaanxi Hospital of Traditional Chinese Medicine from 2017 to 2019.ResultsIn a series of 10.000 upper gastrointestinal endoscopy, 384 patients (3.84%) were found to have GPs. Of these patients, 98 (25.5) were male and 286(74.5) were female. The average age of the patients was 62.8±10.4 (36-75) years. HPs, APs and FGPs frequencies were 88.5%, 5.2% and 2.1%, respectively. The polyp size of 274 (71.3%) patients was ≤ 1 cm. Polyp was identified in 262 (68.2%) patients. The most common polyps are the antrum and the corpus. Endoscopic mucosal resection was performed on 128 patients. Bleeding events have been observed and endoscopic treatment is required after ESP.Conclusion: In current study, GPs frequency was low (3.84%), and HP frequency may be high due to high frequency of Helicobacter pylori (HPy) infection in China. Due to the high frequency of HPy infection and the short-term use of proton pump use, FGP frequency may be low.

“…Histopathological examiniation of common mucosa showed that 29.7% of patients had polyps by EGD. A total of 153 patients (0.59%) were reported in 26 000 endoscopic procedures [22,23] . Among these patients, 41.2% were female and the average age was 64 years.…”

BACKGROUNDAccording to the study population, incidence of gastric polyps (GP) varies from 0.33% to 6.7% in various studies. Most GPs consist of proliferative polyps (HP), gastric fundus polyps (FGP) and adenomatous polyps (APs). Despite the high malignant AP potential, sporadic FGP has no malignant potential.

“…It is suggested to resect HP if they are symptomatic, if they present atypical characteristics, or if they are greater than 1 cm, since they have a greater potential for malignant transformation [ 13 ]. When HPs measure less than 1 cm, biopsy and follow-up should be performed [ 12 , 15 ]. It is also important to perform biopsies of the surrounding mucosa, to rule out the presence of gastritis associated with H .…”

Hyperplastic polyps are the most frequent benign epithelial gastric polyps. Although they are considered nonneoplastic, some cases have been reported with focal adenocarcinoma. We present the case of a 59-year-old woman with a sessile lesion of 15 mm on the distal gastric body associated with an extensive atrophic gastritis. Magnifying endoscopy with Fuji Intelligent Color Enhancement (FICE) revealed an irregular microsurface pattern at the apex, suggesting malignancy. A mucosectomy was performed. The histopathology revealed that the base corresponded to a hyperplastic polyp, where a tubular adenoma with high-grade dysplasia was established, with focal well-differentiated intramucosal tubular adenocarcinoma.
