Background/aims: Duodenal gastric metaplasia seems to be linked to infection by Helicobacter pylori, to the extent of acid secretion and to bulbitis. An investigation was made of the relationship between bulbitis and duodenal gastric metaplasia, or whether bulbitis can arise along with duodenal gastric metaplasia after Helicobacter pylori eradication in an average of six years.
Methodology: We compared 22 patients with duodenal ulcers [male/female 16/6; (mean age+/-SD) 55+/-12 years] Helicobacter pylori-negative after eradication, with 23 Helicobacter pylori-positive patients free from active duodenal ulcers [male/female 17/6; (mean age+/-SD) 59+/-12 years].
Results: The bulbitis score was found to be lower in the Helicobacter pylori-negative than in the Helicobacter pylori-positive group (p=0.02). The duodenal gastric metaplasia score in the Helicobacter pylori-negative was higher than in the Helicobacter pylori-positive group (p=0.001). We failed to find any relationship between the presence of bulbitis and duodenal gastric metaplasia. We found a non-significant inverse correlation between the presence of duodenal gastric metaplasia and chronic body gastritis (p=0.07).
Conclusions: Bulbitis and duodenal gastric metaplasia may depend on different causal factors not related to Helicobacter pylori infection. The extension of duodenal gastric metaplasia with time following recovery from peptic ulcer disease may represent a mucosal protection factor against acid.

We report a rare case of eosinophilic gastrointestinal disorders in a 60-year-old woman, which extensively involved the digestive tract from the esophagus, gastric, duodenum to the small intestine, depicted well by 18F-FAPI-42 PET/CT, superior to 18F-FDG PET/CT. Under the guidance of 18F-FAPI-42 PET/CT, the biopsy was successfully performed, and the diagnosis was established. This case highlights that 18F-FAPI-42 PET/CT may serve as a novel noninvasive method for evaluating eosinophilic gastrointestinal disorders.

Background: Familial adenomatous polyposis (FAP) is an autosomal dominant colorectal tumour syndrome characterised by the formation of multiple adenomatous polyps throughout the colon. It is important to understand the extracolonic phenotype that characterizes FAP. Most previous case reports of patients with both FAP and intellectual disability (ID) have described deletions in all or part of chromosome 5q, including the APC locus.

Background: Simulated microgravity environment can lead to gastrointestinal motility disturbance. The pathogenesis of gastrointestinal motility disorders is closely related to the stem cell factor (SCF)/c-kit signaling pathway associated with intestinal flora and Cajal stromal cells. Moreover, intestinal flora can also affect the regulation of SCF/c-kit signaling pathway, thus affecting the expression of Cajal stromal cells.

Several extra-colonic manifestations, including duodenal polyposis and desmoid tumors, are well-described manifestations in familial adenomatous polyposis (FAP). More recently, an increase in gastric cancer diagnoses has been observed in FAP. This case series presents nine patients with FAP who were diagnosed with gastric cancer at our FAP expertise center, of whom eight were diagnosed between 2017 and 2023, while before 2017 the only diagnosis of gastric cancer was in 2001.
