Background: Duodenal gastric metaplasia (DGM) is commonly found in association with Helicobacter pylori (Hp)-associated gastritis in adults. DGM is also considered a risk factor for duodenal ulcer development. The prevalence of DGM in children and its association with gastritis, duodenitis, or the presence of Hp organisms is not clear. We investigated the prevalence of DGM in children and explore its association with several possible risk factors, including age, gender, gastritis, duodenitis, or Hp presence in the gastric antrum.
Methods: A retrospective analysis of 173 upper endoscopy procedures performed between 1993 and 1995 at Cabell Huntington Hospital, Huntington, WV, was done. Gastric and duodenal biopsies were stained with Giemsa for Hp detection, periodic acid-Schiff for DGM, and hematoxylin and eosin for histologic assessment. Gastric mucosal inflammation was graded according to Sydney criteria.
Results: Duodenal gastric metaplasia was identified in 23 of 173 (13%) patients. Duodenitis but not age, gender, gastritis, or the presence of Hp in the gastric antrum was associated with DGM development. In 4 of 23 DGM foci, Hp was identified.
Conclusions: In children, DGM is not the consequence of Hp infection.

Introduction: Gastrointestinal stromal tumors (GIST), which occur anywhere in the gastrointestinal (GI) tract, typically occur in the stomach and small intestine but rarely in the duodenum. We present a case report wherein a descending duodenal GIST was treated with a limited, minimally invasive surgery after endoscopic nasobiliary drainage (ENBD) insertion.
Presentation Of Case: A 67-year-old woman visited our hospital with an incidentally discovered duodenal tumor.

Introduction And Importance: Superior mesenteric artery (SMA) syndrome, or aorto-mesenteric clamp syndrome, is a rare condition where the third portion of the duodenum is compressed between the aorta and the superior mesenteric artery. This syndrome often affects adolescents and young adults, with predisposing factors including significant weight loss, anatomical variations, and spinal deformities. Early diagnosis and intervention are critical for managing symptoms and preventing complications.

Background: Although bariatric and metabolic surgical methods, including duodenal-jejunal bypass (DJB), were shown to improve metabolic dysfunction-associated steatotic liver disease (MASLD) in clinical trials and experimental rodent models, their underlying mechanisms remain unclear. The present study therefore evaluated the therapeutic effects and mechanisms of action of DJB in rats with MASLD.
Methods: Rats with MASLD were randomly assigned to undergo DJB or sham surgery.
