Angiodysplasia of the colon with preferential localisation in the region the ileocoecal valve is not infrequently the cause of massive gastrointestinal bleeding. The diagnostic problems of this disease are illustrated by seven cases. Contrary to angiography, coloscopy, which may have to be done as an emergency procedure, frequently does not allow localisation of the haemorrhage. Vascular malformations can be demonstrated by arteriography even in the asymptomatic interval. They frequently escape macroscopic identification even in the resected specimen due to their small size and their localisation in the submucosa. The diagnosis can be established histologically by serial sections with vascular filling if necessary. The treatment of choice is resection of the affected part of the gut. In cases of decreased operability endoscopic laser coagulation can be indicated.
结肠血管发育异常，好发于回盲瓣区域，常是胃肠道大出血的原因。本文通过7例病例阐述了该病的诊断问题。与血管造影不同，结肠镜检查（有时可能作为紧急手术进行）常常无法确定出血部位。即使在无症状期，动脉造影也能显示血管畸形。由于其体积小且位于黏膜下层，即使在切除标本中也常常难以通过肉眼识别。如有必要，可通过血管充盈的连续切片进行组织学诊断。治疗的首选方法是切除肠道的受累部分。对于手术可操作性降低的病例，可考虑内镜激光凝固治疗。
