What is the cause of bile reflux gasthropathy?

Probably not: Bile produced in the liver is excreted via the common bile duct through the papilla of Vater. It should flow ante grade into the small bowel. If it flows retrograde into the stomach, it is termed biliary gastric reflux. It was thought that this could be a cause of gastritis. However, this phenomenon is commonly observed on nuclear hepatobiliary scans in patients without gastritis by endoscopy.
