功能性消化不良小儿胃排空的超声检测

Ultrasonographic detection of gastric emptying in children with functional dyspepsia

目的运用超声检测胃内液体排空时间,评价功能性消化不良(FD)小儿胃运动功能状况。方法于饮入液体前后通过超声测量54例FD小儿的胃窦容积,得出胃液体半排空时间。结果本组FD患儿平均胃液体半排空时间为(37.46±12.70)min,其中27例(50%)胃液体半排空时间延迟[平均时间(48.85±10.24)min]。结论小儿FD中确实存在胃排空障碍,年龄、性别、有无胃炎及幽门螺杆菌感染对胃排空时间是否延长无明显影响。超声检查是测量小儿胃排空的一种可靠方法。

Objective To evaluate the gastric motility in children with functional dyspepsia （FD） by detecting the half-time of liquid gastric emptying with ultrasound. Methods The volume of sinus ventriculi in 54 FD children before and after ingesting a fluid meal was measured by ultrasonography, the half-time of liquid gastric emptying was further calculated. Results The average half emptying time were 37.46±12.70 minutes. Among them, 27 （50%） FD children had delayed emptying time （mean 48.85 ±10.24 minutes）. Conclusion It is sure that the gastric emptying time is delayed in part FD children . There is no obvious influence between gastric emptying and age, sex, gastritis, helicobacter pylori（HP）infection. Ultrasonography is a reliable method for measuring gastric emptying time in children.
