A manometric study of duodenal motor activity was performed in 8 duodeno-gastric (D.G.) reflux patients and in 5 healthy volunteers. The examination was done by an open-tip probe containing three catheters which was positioned in the descending portion of the duodenum. The evaluation of manometric data evidenced in D.G. reflux patients a Motility Index (M.I.) significantly higher than that of control subjects in all the three duodenal recording points both in basal conditions and after prostigmine stimulation. Evaluation of the percentage of coordinated waves showed that in D.G. reflex patients the waves had a frequency lower than that in normals. On the basis of these results we can conclude that the duodenum of patients with D.G. reflux exhibits hyperkinetic-dyskinetic disturbances suggesting an important role of the duodenum in determing D.G. reflux.
对8例十二指肠-胃（D.G.）反流患者和5名健康志愿者进行了十二指肠运动活性的测压研究。检查通过一个装有三根导管的开放尖端探头进行，该探头放置在十二指肠降部。对测压数据的评估表明，在基础状态和新斯的明刺激后，D.G.反流患者在所有三个十二指肠记录点的运动指数（M.I.）均显著高于对照组。对协调波百分比的评估显示，D.G.反射患者的波频率低于正常人群。基于这些结果，我们可以得出结论，D.G.反流患者的十二指肠表现出运动亢进-运动障碍性紊乱，提示十二指肠在决定D.G.反流中起重要作用。
