Clinical analysis of correlation between bile reflux Helicobacter pylori infections and residual gastropathy

OBJECTIVE To investigate the clinical significance of bile reflux and Helicobacter pylori infections in patients with residual gastropathy.METHODS From Oct 2008 to Oct 2010,a total of 42 patients with residual gastropathy after subtotal gastrectomy were retrospectively analyzed in the hospital,and the incidence of the bile reflux and the H.pylori infections were analyzed.RESULTS The incidence of bile reflux and H.pylori infections were 57.1% and 37.1%,respectively.The incidence of bile reflux and H.pylori infections were statistically different among the patients with gastric cancer,gastric ulcer,gastritis group(P0.05).The incidence of bile reflux was higher in the Billroth Ⅱ-type than that in the Billroth Ⅰ-type(P0.05).However,The incidence of H.pylori infections was lower in the Billroth Ⅱ-type than that in the Billroth Ⅰ-type(P0.05).The incidence of bile reflux(85.0% vs 31.8%) and H.pylori infections(55.0% vs 27.3%) were higher in the patients with longer than one year treatment than in the patients with less than one year treatment(P0.05).CONCLUSION To choose the reasonable surgery approach to prevent the bile reflux and to actively treat the H.pylori infections are effective ways to prevent the residual gastropathy after subtotal gastrectomy.
