Gastric-type epithelium and islands of oxyntic mucosa in duodenal biopsies are considered by some to be part of a spectrum of metaplastic change related to peptic disorders. This study was designed to assess prevalence and associations of metaplastic-heterotopic gastric mucosa in the duodenum. Demographic, clinical, and histopathologic data from patients who had duodenal biopsy specimens for a 12-month period were collected from a national database. The duodenal findings of patients with duodenitis, gastric metaplasia, and gastric heterotopia were correlated with gastric pathology, Helicobacter pylori status, and clinical information. Of 28 210 patients with duodenal biopsy specimens, 80.9% were healthy, 2.1% had active duodenitis, 2.2% gastric foveolar metaplasia without active inflammation ("peptic duodenopathy"), 4.8% gastric foveolar metaplasia with active inflammation ("peptic duodenitis"), and 1.9% gastric heterotopia. Helicobacter pylori was documented in 9.8% of patients with normal duodenum, 6.9% of those with gastric metaplasia without active inflammation, 15.8% of those with active duodenitis, and 29.1% of those with gastric foveolar metaplasia with active inflammation; 2.2% of 543 patients with gastric heterotopia had H pylori gastritis. Helicobacter pylori was detected in the metaplastic epithelium of 67.6% of patients with active inflammation and in 16.4% of those with metaplasia without inflammation. Gastric heterotopia was strongly associated with concurrent fundic gland polyps. In conclusion, active duodenitis was more common in patients with H pylori infection, but gastric metaplasia was not. We suggest that there is insufficient evidence to ascribe duodenitis with foveolar metaplasia to a "peptic" disorder, as "peptic duodenopathy" and "peptic duodenitis" seem to imply. Gastric heterotopia is likely a congenital lesion; its association with fundic gland polyps suggests that use of proton pump inhibitors may enhance its endoscopic detection.

A synthetic methylprostaglandin E1 analog that reduces gastric acid secretion and enhances the gastric mucus-bicarbonate barrier. It is effective in the therapy of gastric ulcers and gives significant protection against NSAID-induced gastric mucosal damage. The drug also prevents cyclosporin A-induced damage to endocrine and exocrine pancreatic secretions. It shows a low order of acute toxicity and there is no evidence of embryotoxicity, fetotoxicity, teratogenicity, or mutagenicity in animal studies.
Abnormal distention of the STOMACH due to accumulation of gastric contents that may reach 10 to 15 liters. Gastric dilatation may be the result of GASTRIC OUTLET OBSTRUCTION; ILEUS; GASTROPARESIS; or denervation.
Vagal denervation of that part of the STOMACH lined with acid-secreting mucosa (GASTRIC MUCOSA) containing the GASTRIC PARIETAL CELLS. Since the procedure leaves the vagal branches to the antrum and PYLORUS intact, it circumvents gastric drainage required with truncal vagotomy techniques.
Endocrine cells which secrete GASTRIN, a peptide that induces GASTRIC ACID secretion. They are found predominantly in the GASTRIC GLANDS of PYLORIC ANTRUM in the STOMACH, but can also be found in the DUODENUM, nervous and other tissues.
Rounded or pyramidal cells of the GASTRIC GLANDS. They secrete HYDROCHLORIC ACID and produce gastric intrinsic factor, a glycoprotein that binds VITAMIN B12.
