Abstract：
We report the case of a 63-year-old female patient with liver cirrhosis who presented with symptoms of severe hypoalbuminaemia and diarrhoea. After ruling out other causes of hypoalbuminaemia and confirmation of an elevated faecal α-1 antitrypsin clearance, the diagnosis of protein-losing enteropathy (PLE) could be established. Since PLE is a syndrome caused by various diseases, classified into erosive and non-erosive gastrointestinal diseases or lymphatic obstruction, an extensive work-up was necessary, establishing the final diagnosis of Crohn\'s disease.
摘要：
我们报告了一例63岁的女性肝硬化患者，其症状为严重的低白蛋白血症和腹泻。在排除低蛋白血症的其他原因并确认粪便α-1抗胰蛋白酶清除率升高后，可以确定蛋白丢失性肠病(PLE)的诊断.由于PLE是由各种疾病引起的综合征，分为糜烂性和非糜烂性胃肠道疾病或淋巴阻塞，有必要进行广泛的工作，建立克罗恩病的最终诊断。
