继发性小肠淋巴管扩张症一例并文献复习

Secondary intestinal lymphangiectasia： a ease report and review of literature

目的加深小肠淋巴管扩张症（IL）的认识。方法报道1例具有完整临床和病理资料的继发性IL的患者，并结合文献复习进行分析。结果胶囊内镜提示小肠弥漫性黏膜白斑，结肠镜病理提示回肠黏膜组织中淋巴管明显扩张，小肠淋巴管扩张症诊断明确。结论IL是一种罕见病，临床表现缺乏特异性，临床上易误诊，对于以腹泻、浆膜腔积液及低蛋白血症为特点的患者应考虑IL的可能性。

Results Colonoscopy and capsule endoscopy demonstrated dilated lymphatic vessels in the small intestine. The diagnosis was confirmed by intestinal biopsy.
