Evaluation of gastric polyps in patients with upper gastrointestinal endoscopy

Abstract

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.
