Abstract
A total of 258 patients with obscure gastrointestinal bleeding were referred for small bowel enteroscopy, a procedure which allows endoscopic evaluation of most of the small intestine. A small bowel tumour was found in 5% of patients. In 50% of patients no diagnosis could be made, but when the cause of obscure bleeding was discovered small bowel tumours were the single most common lesion in patients younger than 50 years. Small bowel tumours causing gastrointestinal bleeding may remain undetected despite extensive diagnostic evaluation. We conclude that small bowel tumours are the most common cause of obscure gastrointestinal bleeding in patients less than 50 years of age. Small bowel enteroscopy is diagnostic of small bowel tumours even when all previous diagnostic studies, including enteroclysis and angiography, are negative.
摘要
共有258例不明原因的胃肠道出血患者接受了小肠镜检查，该检查可对大部分小肠进行内镜评估。5%的患者发现有小肠肿瘤。50%的患者无法做出诊断，但当发现不明原因出血的病因时，小肠肿瘤是50岁以下患者最常见的单一病变。尽管进行了广泛的诊断评估，导致胃肠道出血的小肠肿瘤仍可能未被发现。我们得出结论，小肠肿瘤是50岁以下患者不明原因胃肠道出血的最常见原因。即使包括小肠灌肠造影和血管造影在内的所有先前诊断研究均为阴性，小肠镜检查仍可诊断小肠肿瘤。
