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 analyze the characteristics of gastroscopy and electrogastrogram of children with abdominal Henoch-Schonlein purpura and provide the basis for the early diagnosis of abdominal Henri-purpura. Methods Twenty-nine children with Henoch-Schonlein purpura with abdominal pain as the first symptom were examined by gastroscopy and electrogastrogram to observe the pathological changes of stomach and duodenal mucosa and the change of electrogastrogram. Results Gastroscopy showed that the stomach and duodenal mucosa showed varying degrees of congestion, edema, erosion or even ulcer, with lesions of the descending part of the duodenum, esophageal mucosa showed no abnormalities. The gastrogram of children with idiopathic purpura showed an increase in mean postprandial amplitude (Vpp), a decrease in the dominant frequency (DF), and a decrease in the percentage of normal pre-meal P wave (PNSW). Conclusion Abdominal hypersensitivity purpura gastroscopy and electrogastrogram with characteristic changes provide the basis for the early diagnosis of abdominal Henoch-Schonlein purpura.
