Analysis of endoscopic and histopathological features of gastric polyps

Objective: Gastric polyps are sessile or pedunculated lesions that originate from the gastric epithelium or submucosa and protrude towards the lumen, with a rate of 2-6%. There is a risk of malignant transformation in gastric polyps. In our study, we aimed to evaluate the characteristics of gastric polyps in our region. Materials and methods: The study was carried out with the retrospective evaluation of esophagogastroduodenoscopy performed in the Gastroenterology clinic of our hospital between July 2020 and June 2022. Results: Esophagogastroduodenoscopy was performed in a total of 2669 patients, and 182 polyps detected in 96 patients were examined. Thirty-six (37.5%) of the patients were male, 60 (62.5%) were female, and the median age was 59 (22-88). Sixty-two (34%) of the polyps were in the antrum, 109 (59.9%) were in the corpus, and 11 (6.1%) were in the fundus. Histopathologically, 151 (83%) polyps were hyperplastic polyps, 4 (2.2%) adenomas, 24 (13.2%) fundic gland polyps, and 3(1.6%) neuroendocrine tumors. There was no statistical relationship between gender and intestinal metaplasia, atrophy and hp positivity. There was also no statistical relationship between hp positivity and intestinal metaplasia. Conclusions: The frequency, anatomical locations and histopathological types of gastric polyps may vary according to the geographical region where the study is performed. In our study, polyps were most common in the corpus and most of them were hyperplastic. Unlike colorectal hyperplastic polyps, gastric hyperplastic polyps have the potential to become malignant. it would be appropriate to remove all gastric polyps and examine them histopathologically.
