要旨●好酸球性多発血管炎性肉芽腫症(EGPA)の消化管病変の特徴を明らかにするために,自験10例のX線・内視鏡所見を遡及的に検討した.平均年齢53.2歳,男性7例,女性3例であった.食道・胃に明らかな病変を認めなかったが,小腸潰瘍を5例(十二指腸2例,空腸・回腸2例,終末回腸1例)に認めた.大腸病変は10例全例に認められ,特に遠位大腸優位に病変が好発していた(p=0.015).小腸・大腸病変は多発し,周囲に発赤を伴うびらん・潰瘍が病変の主体であった.以上より,本症の消化管病変の特徴は,遠位大腸を中心としたびらん・潰瘍性病変,および小腸潰瘍と考えられた.
To determine the characteristics of GI(gastrointestinal)involvements in patients with EGPA(eosinophilic granulomatosis with polyangiitis), we reviewed the findings of GI examinations in 10 such patients. The 10 patients included 7 men and 3 women, with an average age of 53.2 years. GI involvements were found in the duodenum in 2, jejunum or ileum in 2, terminal ileum in 1, and colorectum in all patients. Colorectal involvements were more frequent in the distal colorectum than in the proximal colon(p=0.015). Multiple erosions or ulcerations accompanied by marginal reddish mucosa were considered to be the characteristic GI findings. Distal colorectum was the most frequently involved site in EGPA. Small intestine seems to be frequently involved in the disease ; however, further investigation is necessary.
