Patients with this pathology represents a difficult problem in differential diagnosis. Clinical findings and radiologic studies could help but endoscopy is now the most precise method in order to determine the site and nature of hemorrhage. We performed 504 colonoscopies in colon hemorrhage finding that our most frequent cause were polyps in both, children and adults in 199 cases (39%); diverticular disease was the second with 131 patients (26%) and third carcinoma with 52 (10%). Other causes were amebic colitis in 47 (8%); inflammatory bowel disease in 28 (6%) and infectious colitis in 13 (3%). Risks, complications and limitations of colonoscopy, as well as its great utility in diagnosis and treatment of colonic hemorrhagic lesions are commented.
患有这种病理情况的患者在鉴别诊断中是一个难题。临床症状和放射学检查可能会有所帮助，但内镜检查现在是确定出血部位和性质的最精确方法。我们对结肠出血患者进行了504次结肠镜检查，发现最常见的病因在儿童和成人中都是息肉，共199例（39%）；憩室病位居第二，有131例患者（26%），第三位是癌，有52例（10%）。其他病因包括阿米巴结肠炎47例（8%）；炎症性肠病28例（6%）和感染性结肠炎13例（3%）。文中还讨论了结肠镜检查的风险、并发症和局限性，以及其在结肠出血性病变诊断和治疗中的巨大作用。
