Multiple acute erosions of the antrum. Grossly, most erosions and acute ulcers appear as well-defined hemorrhagic lesions 1 to 2 mm in diameter. If the insult is severe, the mucosa between the lesions is intensely hemorrhagic. Microscopically, an erosion demonstrates necrosis to the level of the muscularis mucosa-

Multiple acute erosions and some ulcers are observed. Nonsteroidal anti-inflammatory drugs (NSAIDs), such as aspirin, ibuprofen, and piroxican, can be direct irritants and can cause of gastritis.

There are duodenal ulcers as well as some duodenal erosions. Though primary and secondary duodenogastric reflux (DGR) have been accepted in the medical literature as separate clinical units, reliable and standardised methods of detection have not been known since long. Therefore, the role of DGR in the pathogenesis of upper GI tract diseases makes a problem.
