What does small bowel reflux mean?

Biliary reflux: Biliary reflux, bile reflux or duodenogastric reflux is a condition that occurs when bile flows upward (refluxes) from the duodenum into the stomach and esophagus. While bile reflux involves fluid from the small intestine flowing into the stomach and esophagus, acid reflux is back flow of stomach acid into the esophagus. SEE: http://bit.ly/1CERl6k
