![]() ![]() We, hereby, evaluated the value of mapping in determining the extent and severity of IM. *Ankara University School of Med., Turkeyīackground & objectives: Uneven distribution of gastric intestinal metaplasia (GIM) may require mapping biopsies rather than random biopsies which may fail to reflect the extent of the lesions. Road-mapping for gastric intestinal metaplasiaĮ.K. Intestinal-type adenomas occurred predominantly in the distal stomach (62.5%, p=0.031), were larger than 7mm in 9/16 cases (56.3%, p=0.03), and were more frequently associated with duodenal adenomas (87.5%, p7mm) and/or duodenal adenomas. Foveolar-type adenomas and pyloric gland adenomas were not identified in this series. Half of FAP patients (n=28, 50.0%) developed endoscopically visible gastric polyps, including FGPs in 12 patients (21.4%) and adenomas with or without FGPs in 16 patients (28.6%). ![]() Results: Our series encompassed 95 gastric polyps, including 53 (55.8%) fundic gland polyps (FGPs) without dysplasia (n=34) or with dysplasia (n=19) and 42 (44.2%) intestinal-type adenomas. IBM SPSS (Release 27.0) was used for statistical analysis. Clinico-pathological features, with particular emphasis on periodic upper endoscopic examinations, were studied. Thirty-two patients were males (57.1%), and the medium age was 52 (range: 26-87). ![]() Methods: Fifty-six FAP patients followed up at our hospital in High-Risk Consultation of Digestive Tumours, from 1992 to 2021 were retrospectively selected. As the prevalence of Helicobacter-pylori infection in Portugal is up to 90%, we aim to characterize gastric polyps in a series of Portuguese patients. * Pathology Department, Centro Hospitalar Universitário de São João (CHUSJ), Portugalīackground & objectives: Chronic atrophic gastritis may contribute to the phenotype of gastric polyps in familial adenomatous polyposis (FAP). ![]() Gastric polyps in familial adenomatous polyposis (FAP) Portuguese patients - the first Western cohort with Asian featuresĭ.
