Angiomas are mucosal and/or submucosal lesions that cannot be visualized on routine barium x-ray films. Endoscopy can establish the diagnosis in lesions of the upper gastrointestinal tract, and colonoscopy and arteriography are used for examination of the colon. Various endoscopic coagulation devices are available to stop the bleeding and treat the angioma. Our experience indicates that the patient, rather than the type of endoscopic treatment, often dictates outcome. Patients with abnormal bleeding times, chronic renal failure, or severe heart disease often have poorer palliation results, higher complication rates, and faster recurrence rates. Even patients without these poor prognostic factors tend to have recurrences of angiomas and bleeding.
血管瘤是黏膜和/或黏膜下病变，在常规钡餐X线片上无法显影。内镜检查可对上消化道病变进行诊断，结肠镜检查和血管造影用于结肠检查。有多种内镜下凝血设备可用于止血和治疗血管瘤。我们的经验表明，决定治疗结果的往往是患者本身，而非内镜治疗的类型。出血时间异常、慢性肾衰竭或严重心脏病患者的缓解效果往往较差、并发症发生率较高且复发率较快。即使没有这些不良预后因素的患者也容易出现血管瘤复发和出血。
