I have reviewed the English language literature on angiodysplasia of the upper gastrointestinal tract. Angiodysplasia is a distinct mucosal vascular lesion associated with acute or chronic gastrointestinal bleeding. Its etiology is unknown, but theories of its pathogenesis have evolved from its similarity to colonic angiodysplasia and an association with renal failure. Despite recurrent gastrointestinal bleeding, the endoscopic diagnosis is difficult because the lesions are so small and so similar to fresh blood. Endoscopic ablation by electrocautery or laser photocoagulation can reduce bleeding or make it stop, but repeated treatments are often necessary.
我已查阅了关于上消化道血管发育异常的英文文献。血管发育异常是一种与急性或慢性胃肠道出血相关的独特黏膜血管病变。其病因尚不清楚，但其发病机制理论已从其与结肠血管发育异常的相似性以及与肾衰竭的关联演变而来。尽管存在反复的胃肠道出血，但内镜诊断仍很困难，因为病变非常小且与新鲜血液极为相似。通过电灼或激光光凝进行内镜下消融可减少出血或使其停止，但通常需要反复治疗。
