摘要
目的分析儿童腹型过敏性紫癜的胃镜及胃电图特点,为腹型过敏性紫癜的早期诊断提供依据。方法 对29例以腹痛为首发症状的过敏性紫癜患儿进行胃镜及胃电图检查,观察胃、十二指肠黏膜病变特点及胃电图的变化。结果 胃镜检查显示胃和十二指肠黏膜呈现不同程度的充血、水肿、糜烂甚至溃疡,以十二指肠降部病变为著,食管黏膜未见异常。腹型过敏性紫癜患儿胃电图示餐前、餐后平均幅值(Vpp)增高,主频率(dominant frequency,DF)降低,餐前正常慢波百分比(PNSW)减少。结论 腹型过敏性紫癜的胃镜及胃电图具有特征性变化,为腹型过敏性紫癜的早期诊断提供了依据。
Objective To analyse appearance of gastroscope and electrogastrogram（EGG） in the anaphylactoid purpura abdominalis in children and provide a guide for early diagnosis.Methods 29 cases diagnosed anaphylactoid purpura abdominalis were examined by gastroscope and EGG.Mucosal lesions of stomach and duodenum were observed.Characteristics of EGG were analyzed.Results The gastroscope appearance of stomach and duodenal mucous were congestive,swelling,dissipated and even ulcer.Mucosal lesions were more serious in the descending duodenum.The oesophageal mucous was normal.Preprandial and postprandial value of Vpp of EGG were higher than those in healthy children.Dominant frequency of gastric slow were significantly deacreased.Percent of normal slow wave during preprandial decreased.Conclusion Gastroscope and EGG offer early diagnostic value in the anaphylactoid purpura abdominalis.
