Objective To investigate the clinical value of radiopaque markers method on gastrointestinal motility.Methods Using self-made markers,2 mm?2 mm,20 markers were put into a capsule.42 patients with functicnal dypepsia(FD),50 patients with chronic functional constipation(CFC)and 20 healthy controls were included in the study.Each subjects ingested a capsule together with standard food and plain abdominal films were made after 4 h,48 h and 72 h.Gastric emptying rate at the fourth hour,gastrointestinal emptying rate at 48 h and 72 h and emptying index at 72 h were calculated.Results 66.6%(28/42)FD patients had delayed gastric emptying rate.Gastrointestinal emptying rate at 48 h and 72 h were lower in CFC patients than in controls (?
