title: [Duodenogastric reflux and gastric pathology in the elderly patients].
abstract: OBJECTIVE
  To determine the frequency of duodenogastric reflux (DGR), and to assess the changes in the gastric mucosa in the presence of bile reflux.
  
  
  METHODS
  Our study includes the results of 1371 gastroduodenoscopies carried out in 2008, for patients between 65 and 92 years old, the study includes both kind of patients who were admitted to hospital and those who were investigated on an outpatient basis. The main group includes 695 patients with various level of DGR severity, and the control group consists of 676 patients without DGR.
  
  
  RESULTS
  DGR was diagnosed in 14.8% more in women. In case of the presence of DGR we have found changes in the antrum mucosa as congestion, and minor erosion, hyperplasia, metaplasia of gastric and esophageal mucosa, and stomach polyps. And we have not noticed such changes when DGR was absent. We have found that the high frequency of antral hyperplasia is correlated to the DGR severity.
  
  
  CONCLUSIONS
  DGR is diagnosed in more than 10% of patients who undergo gastroduodenoscopy. DGR is an indicator of conditions often associated with various morphological changes in gastric mucosa; therefore this finding has to be taken in consideration in the further investigations and management of such patients.
