观察功能性消化不良（ＦＤ）患者胃排空率及胃窦收缩幅度的情况。方法采用胃Ｂ超增效液定时观察１２３例ＦＤ患者和５９例健康志愿者。结论ＦＤ组３０ｍｉｎ、６０ｍｉｎ的排空率分别为（５１．２３±１５．２）％、（７９．９５±２２．８５）％，而５９例对照组的胃排空率分别为（７５．１６±１３．４）％、（９８．０７±５．４８）％，经统计学处理两组有非常显著性差异（Ｐ＜０．０１）。ＦＤ组胃窦收缩幅度为３．３１±１．３５，对照组为５．２５±１．９７，ＦＤ组收缩幅度明显小于对照组，在统计学上亦有明显差异（Ｐ＜０．０１）。结论胃动力障碍是ＦＤ发病的主要因素。
To observe the gastric emptying rate and gastric antrum contractility in patients with functional dyspepsia (FD). Methods 123 cases of FD patients and 59 healthy volunteers were observed regularly by using gastric juice super-enhancing fluid. Conclusion The emptying rates of FD group at 30min and 60min were (51.23 ± 15.2)% and (79.95 ± 22.85)%, respectively. The gastric emptying rates of the 59 control group were (75.16 ± 13.4% and 98.07 ± 5.48% respectively. There was a significant difference between the two groups (P <0.01). The amplitude of gastric antrum contractions in FD group was 3.31 ± 1.35 and in control group was 5.25 ± 1.97, the contraction amplitude in FD group was significantly lower than that in control group (P <0.01) . Conclusion Gastric motility disorder is the main factor in the pathogenesis of FD.
