为了探讨功能性消化不良（ＦＤ）患者胃排空状况，采用固体试验餐和放射性核素显像法对符合诊断标准的ＦＤ患者１８例，正常（对照）组１６例进行了胃排空检查。结果显示，ＦＤ患者胃排空前的延迟时间，即延迟期（ＬＰ），较对照组明显延长（Ｐ＜０．０５）；胃半排空时间（ＧＥＴ１／２）亦明显延长（Ｐ＜０．０１）；从餐后１５分起，各时段的胃排空率（ＧＥＲ）均明显低于对照组（Ｐ＜０．０１）。以对照组ｘ±２ｓ为诊断标准，则ＦＤ组７２．２％患者的ＬＰ延长，６６．７％患者的 ＧＥＴ １／２延长，５５．６％患者的 ６０分 ＧＥＲ减低。因此，核素胃排空显像能很好地反映胃的运动功能，对ＦＤ的诊断和疗效判断有一定的临床价值。
To investigate gastric emptying in patients with functional dyspepsia (FD), 18 cases of FD patients who met the diagnostic criteria and 16 cases of normal (control) patients underwent gastric emptying examination by solid test meal and radionuclide imaging. The results showed that the pre-gastric emptying delay (FD) of patients with FD was significantly longer than that of the control group (P <0.05), and the gastric partial emptying time (GET1 / 2) .01). The gastric emptying rate (GER) at each time point was significantly lower than that of the control group (P <0.01) from 15 minutes after the meal. With the control group x ± 2s as the diagnostic criteria, LP prolongation in 72.2% of FD patients, prolongation of GET 1/2 in 66.7% of patients and decrease of 60% in 55.6% patients in FD group. Therefore, radionuclide imaging of gastric emptying can well reflect the motor function of the stomach, the FD diagnosis and efficacy of judgments have some clinical value.
