DEN Open, Volume 6, Issue 1, April 2026.ABSTRACT We report a gastric foveolar‐type hyperplastic polyp of the duodenum harboring mutations in the GNAS and KRAS genes. The lesion was incidentally detected during a routine upper gastrointestinal endoscopy in a man in his 50s. It appeared as a 10‐mm elevated lesion located at the superior duodenal angle.

DEN Open, Volume 6, Issue 1, April 2026.ABSTRACT Objectives Approximately 10%–30% patients with familial adenomatous polyposis (FAP) develop gastric neoplasms (GNs). Although recent reports have suggested the effectiveness of gel‐immersion endoscopic mucosal resection (GI‐EMR) for FAP‐associated GNs, given its simplicity and safety, treatment outcomes for such lesions have not been evaluated.

DEN Open, Volume 6, Issue 1, April 2026.We analyzed 9,940,870 endoscopic procedures from the Japanese Endoscopy Database (2015–2023), identifying 9,669 eosinophilic gastrointestinal disease (EGID) cases. The prevalence of eosinophilic esophagitis, gastritis, and duodenitis increased significantly (p < 0.001), while enteritis and colitis remained unchanged (p = 0.136). EoE rose from 36 cases (

DEN Open, Volume 6, Issue 1, April 2026.ABSTRACT Herein, we report a rare case of gastroduodenitis associated with ulcerative colitis (UC). A 42‐year‐old man was diagnosed with UC 1 year prior to admission to our hospital. The patient underwent a 3‐stage total colectomy and ileal pouch‐anal anastomosis for severe UC.

Helicobacter, 2011
AbstractThe last year has seen an interesting and important collection of evidence presented in the field of the “other” than Helicobacter pylori Helicobacters. Associations with adult ulcerative colitis and biliary/hepatic disease have been described. New insights into the immune response and subsequent pathogenesis associated with infection have also

Current Opinion in Internal Medicine, 2003
Helicobacter pylori is an important human pathogen, responsible for most peptic ulcer disease, gastritis and gastric malignancies. H. pylori has several unique features: it is highly adapted for gastric colonization, yet it produces clinical consequences in a small minority, its genome is known, and it is the only bacterium strongly associated with ...

Comparison of isolates of Helicobacter pylori and Helicobacter mustelae [PDF]
Journal of Clinical Microbiology, 1991 On the basis of analysis of protein profiles, isolates of Helicobacter pylori and Helicobacter mustelae were less than 40% similar. Cytotoxin produced by H. pylori was not detected in isolates of H. mustelae. Both bacterial species agglutinated human erythrocytes. These results substantiate a taxonomic difference between H. pylori and H. mustelae.

Helicobacter pylori is associated with various gastroduodenal diseases such as peptic ulcer, functional dyspepsia, MALT lymphoma and distal gastric cancer. Diagnosis of H. pylori can be established by non-invasive ((13C)urea breath test, stool antigen test, serology) and invasive (histology, rapid urease test, culture) tests.

Helicobacter pylori is an important cause of chronic active gastritis and is strongly associated with peptic ulcer disease and gastric cancer. H. pylori colonizes the surface of the gastric epithelium with production of a number of factors, resulting in inflammation and an altered mucosa. H.

Helicobacters and Extragastric Diseases
Helicobacter, 2009AbstractFor two decades, Helicobacter pylori has been considered as the culprit in many extragastric manifestations. However, for several of these supposed associations the hypothesis of an etiological role has not yet been fully investigated. This may be due to a series of factors linked to the epidemiological features of the studies and to the ...
