title: Effects of bile reflux and intragastric microflora changes on lesions of remnant gastric mucosa after gastric operation.
abstract: OBJECTIVE
  To investigate the effects of bile reflux and intragastric microflora changes on lesions of remnant gastric mucosa after gastric operation.
  
  
  METHODS
  Concentration of bile acid and total bacterial counts (TBC) in gastric juice were measured in 49 patients with peptic ulcer before and after gastrectomy. One year after the operation, sample of gastric mucosa taken from all the patients were used for histological examination.
  
  
  RESULTS
  The concentration of gastric bile acid was significantly increased in group B-I, or B-II and SV+A than that in group HSV (P<0.05-0.01). The abnormal histological changes in the remnant gastric mucosa were more common in the first 2 groups than in the last group.
  
  
  CONCLUSIONS
  The type of gastrectomy can affect bile reflux. The abnormal histological changes in the remnant gastric mucosa are closely related to the elevation of bile acid concentration and increase of TBC in gastric juice. HSV can effectively prevent bile reflux and keep the gastric physiological functions stable.
