摘要
目的探索用钡剂替代标记物进行结肠运输试验的检查方法。资料与方法运用结肠运输试验观察正常人和便秘患者的结肠运输情况,分别计算结肠24、48、72小时钡剂及不透光X线标记物的排空率。结果正常组72小时均排出80%或以上的钡剂,慢传输型便秘(slow transit constipation,STC)患者组72小时均未排出80%的钡剂,同一便秘患者短期内标记物与钡剂的排空率无显著差异。结论硫酸钡可替代标记物进行结肠运输试验的检查。
Objective To study colonic transit test with Barium sulfate in healthy subjects and constipation patients instead of radiopaque marker. Materials and Methods A colonic transit test with Barium sulfate or radiopaque marker was performed to observe colonic movement in 74 healthy subjects and 33 constipated patients. Results More than 80% Barium sulfate was emptied in 72 hours in healthy subjects. Less than 80% Barium sulfate was emptied in all slow transit constipation patients in 72 hours. There was no significant difference between emptying ratio of Barium sulfate and radiopaque marker. Conclusion Barium sulfate might substitute radiopaque marker in colonic transit test.
