同时采用胃窦面积和胃底－体交界前后壁内径实时超声显像法对１３例功能性消化不良（ＦＤ）和１０例健康志愿者对照。观察比较两组的胃液体排空功能，并判断西沙必利的促动效果。结果显示：ＦＤ组与对照组比较，除胃底－胃体交界前后壁内径５０％胃排空时间外，两种方法的胃５０％、８０％和１００％胃排空时间均明显延长（ｐ＜０．０１）投予西沙必利１０ｍｇ后，ＦＤ组的胃排空时间明显缩短（ｐ＜０．０１），健康对照组服药前后无显著差异性（ｐ＞０．０５），测量胃窦面积与胃底－体前后壁内径两种方法结果无显著差异性（ｐ＞０．０５）。提示：胃实时超声是研究胃动力学的一种简便、准确又无放射性的方法。西沙必利对ＦＤ患者具有显著的胃促动、加速胃液体排空的作用。
Thirteen patients with functional dyspepsia (FD) and 10 healthy volunteers were enrolled in this study by real-time ultrasound imaging of antrum area and anterior and posterior wall of the fundus-body junction. The gastric emptying function was observed and compared between the two groups, and the motivation of cisapride was evaluated. The results showed that 50%, 80% and 100% gastric emptying time of the two methods were significantly prolonged except for the gastric emptying time of 50% of the anterior and posterior wall of the stomach in the FD group compared with the control group (p <0.01), the time of gastric emptying in FD group was significantly shorter (p <0.01) after administration of cisapride 10 mg, there was no significant difference (P> 0.05) before and after administration of cisapride in gastric antrum There was no significant difference between the two methods (P> 0.05). Tip: Gastric real-time ultrasound is a simple, accurate and non-radioactive method of studying gastric dynamics. Cisapride has a significant gastric motility in FD patients and accelerates gastric emptying.
