ABSTRACT
Objective To study emptying of gallbladder in children with functional dyspepsia(FD),and to investigate correlation of their helicobacter pylori(Hp) status and gallbladder emptying rate.Methods Sixty children with FD were studied,including 30 Hp-ne-(gative) and 30 Hp-positive children.Thirty Hp-positive children received triple eradication therapy 1 week.After 4 weeks,the Hp tests were taken again,27 children became Hp-negative,and the others were still positive eliminated from the study.The difference between the above groups in gallbladder volumes before breakfast and postprandial gallbladder emptying rate were compared.Results The gallbladder volumes before breakfast were bigger and the emptying rate of postprandial gallbladder of children with FD were lower than those of normal controls(P0.05).Conclusions Delayed emptying of gallbladder may cause FD in children.Hp infection isn′t associated with the gallbladder emptying rate.
