【 要旨 】 腸管型Behcet病が出血をきたす頻度については,手術例を分母とした場合約17%との報告がみられる.しかし術前診断はBehcet病の診断がすでについているか,これを疑わせる既往のある場合を除いて困難である.出血の原因となる病態は定型的な小腸潰瘍,次いでびまん性の大腸炎が多く,まれには直腸膣瘻,血管型ではあるが術後大動脈十二指腸瘻の報告がある.肝静脈閉塞によるBudd-Chiari症候群,上腸間膜動脈閉塞による虚血性腸炎,門脈閉塞による側副血行路の発達も出血の原因になることを否定できない.内科的治療が優先されるが,手術を行う場合はskip病変は内科的治療にゆだねて腸管温存に努め,吻合部の数を少なくする.

[ Summary ] According to a report on surgical cases, the incidence of gastrointestinal bleeding in intestinal Behcet's disease is approximately 17 percent. Correct preoperative diagnosis of this disease, however, is apparently difficult except in those patients who have already been diagnosed as having Behcet's disease or have a past history suggestive of this disease. The principal pathologies causing gastrointestinal bleeding include typical small intestinal ulcers and diffuse-type colitis. Recto-vaginal fistulas and post-operative aorto-duodenal fistulas, which are classified under vasculo-Behcet's disease, are rare causes of bleeding. Budd-Chiari's syndrome resulting from hepatic venous occlusion, ischemic enteritis caused by superior mesenteric artery occlusion, and vascular by-passes formed as a result of portal venous occlusion are potential causes of gastrointestinal bleeding. Non-surgical treatment is generaly recommended. However, if surgery is indicated, skip-lesions may be left and managed with medical therapy, and intestinal resections with anastomoses should be minimized.
