常见胃动力异常症状与胃电改变的关系研究

A Study on the Relationship Between Gastric Dyskinetic Symptoms and Electrogastrograms

为探讨胃动力异常症状与胃电改变的关系，对７１例消化系统疾病及１７例其他疾病的胃动力紊乱症状进行统计，并与２８例随机受检者比较，结果显示，消化系统疾病患者餐后饱胀、嗳气、返酸及恶心呕吐等胃动力异常症状的出现率显著高于随机受检者。以微电脑胃肠电检测分析系统作体表胃电检查及功率谱分析，结果发现，在有餐后饱胀、嗳气、恶心呕吐、返酸等症状的患者，其胃电频率、空腹与餐后的胃电活动量以及餐后反应表现不同类型的异常。这可解释有关胃动力异常症状发生的部分病理生理机制。

The incidences of gastric dyskinetic symptoms (GDS) in 71 cases of gastrointestinal diseases and 17 of other diseases were investigated to explore the relationship between gastric dyskinetic symptoms and electrogastrograms and compared with those in 28 healthy adults. The results showed that the incidences of postprandial distenstion, eructaion, acid regurgitation, nausea, vomiting in patients with gastrointestinal diseases were significantly higher than those in healthy adults. The Microcomputer Detect-analyzing System for Electric Activities of Gastrointestinal Tract was used to detect electrogastrogram (EGG) and analyze the frequency spectrum. It was found that EGG frequency, fasting and postprandial EGG activities in the patients with GDS were in different types compared with those without the corresponding symptoms. This will be helpful to explain the kinetics mechanism of GDS and may supply an evidence for clinical diagnosis and treatment.
