目的探讨功能性消化不良(FD)患者胃动力障碍与消化不良症状之间的关系。方法应用核素法检测症状严重程度不同的FD患者的固体食物排空及餐后胃内食物分布情况,并设正常对照组20例进行比较。结果症状轻微和症状严重的FD患者与对照组相比均存在胃排空时间的延长,但两组FD患者胃排空时间没有显著的差异;症状轻微的FD患者与对照组相比餐后胃内食物分布参数没有显著的差异,而症状严重的FD患者与对照组相比差异显著。两组FD患者相比餐后胃内食物分布参数存在显著差异。结论 FD患者的胃排空与消化不良症状之间存在不一致的现象,但胃内食物分布异常可能是一部分FD患者产生消化不良症状的原因。
Objective To investigate the relationship between gastric dysfunction and dyspeptic symptoms in patients with functional dyspepsia (FD). Methods The nuclide method was used to detect the emptying of solid food and the food distribution in the stomach after FD patients with different symptom severity. 20 normal controls were also compared. Results FD patients with mild symptoms and severe symptoms had prolonged gastric emptying time compared with the control group. However, there was no significant difference in gastric emptying time between the FD patients and the mild FD patients compared with the control group There was no significant difference in the distribution parameters of food, while the symptoms of FD patients were significantly different from the control group. There were significant differences in postprandial food distribution parameters between two groups of FD patients. Conclusion There is an inconsistency between gastric emptying and dyspeptic symptoms in FD patients. However, the abnormal distribution of food in the stomach may be responsible for the dyspeptic symptoms in some FD patients.
