Bile reflux gastritis has been recognized as a significant cause of dyspepsia in a subset of patients. This patient group set does not respond to the standard treatment (not expected to) and some get improvement with the treatment of H.Pylori infection if one is diagnosed at the time of upper endoscopy and biopsy.
Inflammation and Foveolar hyperplasia are some of the findings that can be seen endoscopically. This and other findings have all been documented in the literature. An article published in 2005, reported over 40% incidence of Foveolar hyperplasia in patient with bile relax.
It is been noted that bile causes the thickening of the mucosa lining of the GI track. This is called Foveolar hyperplasia when the mucosa of the stomach is noted to be thicker with more numerous and deeper folds.
The treatment for this is reduction and prevention of bile reflux to the stomach, in some cases this can only achieved by surgical diversion of the bile from the stomach. Additional information on Bile Reflux and the surgical treatment can be found here.
