他们的两名患者没有胃肠道出血源，后来被诊断为膀胱移行细胞癌。这可能是他们贫血的原因，并可能通过尿液分析发现，从而避免了广泛的胃肠道检查。他们的14名未确诊的患者中，有些可能也有凝血功能障碍。我以前描述过一个克罗恩病的无症状患者，由于维生素K吸收不良而出现胃肠道出血。尿液分析和凝血研究的侵入性较小，比钡或内窥镜检查便宜得多。在所有不明原因出血的情况下都应进行这些检查。
Two of their patients with no gastrointestinal source of bleeding were later diagnosed as having transitional cell carcinoma of the bladder. This might have been the cause of their anaemia and might have been detected by urine analysis, thus avoiding extensive gastrointestinal investigations. Some of their 14 undiagnosed patients might also have had a coagulation disorder. I have previously described an otherwise asymptomatic patient with Crohn's disease who hada gastrointestinal bleed due to vitamin K malabsorption.'Urine analysis and coagulation studies are less invasive and much cheaper than barium or endo-scopic studies. They should be performed in all cases of bleeding of obscure origin.
