Abstract: Objective To detect the delay of gastric emptying in bile reflux gastritis with radio-opaque markers.Methods 80 cases were divided into 3 groups,27 cases as healthy control(HC);32 patients with primary bile reflux gastritis(PBRG),and 21 with secondary bile reflux gastritis(SBRG).All the cases took the same amount of test meal which contained a capsule with 20 barium sulfate pieces.Gastrointestinal fluoroscopy was performed after meals 120 and 240 min respectively.Then the rate of gastric emptying was measured.Results There was significant delay in gastric emptying of solids for PBRG patients compared with HC and SBRG patients(P<0.05).Compared with HC cases,the gastric emptying of solids for SBRG patients showed somewhat delay but there was no statistically significant difference between them(P>0.05).Conclusion PBRG patients show significant gastric emptying disturbance with radio-opaque markers.SBRG patients do not show significant delay of gastric emptying.
