Intestinal lymphangiectasia is defined as a dilatation of small bowel lymphatic capillaries and a loss of lymph into the bowel lumen. Clinically it is characterized by hypoproteinaemia and oedema. We present here a case of protein-losing enteropathy due to intestinal lymphangiectasia after liver transplantation in a 57-year-old man who was transplanted for hepatitis C virus. Four years after liver transplantation, the patient developed hypoalbuminaemia and ascites associated with recurrence of cirrhosis. The sudden fall in serum albumin led us to look for a cause of reduction other than or in addition to cirrhosis. Duodenal biopsies showed tall villi with dilated lymphatic vessels and widening of the villi caused by oedema, demonstrating intestinal lymphangiectasia. In this case a low-fat diet supplemented with medium-chain triacylglycerols achieved an early clinical improvement with increased serum albumin levels and ascites disappearance. Intestinal lymphangiectasia should be suspected in liver-transplanted patients developing hypoproteinaemia and hypoalbuminaemia after the recurrence of cirrhosis.
肠淋巴管扩张症的定义为小肠淋巴管扩张以及淋巴液漏入肠腔。临床上其特征为低蛋白血症和水肿。我们在此呈现一例57岁因丙型肝炎病毒接受肝移植的男性患者,在肝移植后发生肠淋巴管扩张症所致的蛋白丢失性肠病。肝移植四年后,患者出现低白蛋白血症和腹水,伴有肝硬化复发。血清白蛋白的突然下降促使我们寻找除肝硬化之外或与其并存的白蛋白降低原因。十二指肠活检显示绒毛高且淋巴管扩张,绒毛因水肿而增宽,证实存在肠淋巴管扩张症。在此病例中,补充中链甘油三酯的低脂饮食使血清白蛋白水平升高且腹水消失,从而实现了早期临床改善。对于肝硬化复发后出现低蛋白血症和低白蛋白血症的肝移植患者,应怀疑存在肠淋巴管扩张症。
