title: [Cholecystectomy and duodenogastric reflux].
abstract: With the aim of evaluating whether cholecystectomy causes an increase in duodenogastric reflux (DGR) 34 patient (12 males and 22 females, mean age 50 years) were examined before and 6 months after cholecystectomy. DGR was evaluated by assaying total and individual biliary acids in gastric juice and was expressed as fasting bile reflux (FBR) in mumol/h. The histology of gastric mucosa in endoscopic biopsies taken from the antrum and body was also analysed. FBR of total biliary acids rose from 2.4 mumol/h before surgery to 41.33 mumol/h after cholecystectomy (p = 0.000). A significant increase was observed for all the individual biliary acids. Histological tests of gastric mucosa revealed an increased percentage of chronic atrophic gastritis of the antrum following cholecystectomy. Histological conditions in the body were unaltered. The results of this study show that there is a significant increase in DGR (months after cholecystectomy together with increased histological damage to the mucosa of the antrum. Further studies are necessary in order to evaluate whether the two phenomena are related.
