Duodenogastric reflux and bile reflux gastritis

Reflux of duodenal contents, including bile, pancreatic enzymes, and alkaline intestinal contents, into the stomach is termed duodenogastric reflux. Alkaline reflux or bile reflux is a common pathological phenomenon. Patients often complain of persistent pain in the mid-upper abdomen, which worsens after meals, is not relieved by antacids, and may even be aggravated by them.
