摘　　要：目的探讨直接淋巴管造影术后CT对继发性小肠淋巴管扩张症的诊断价值。方法回顾性分析我院自2007年4月至2012年5月共收治的14例继发性小肠淋巴管扩张症患者的直接淋巴管造影术后CT资料,并与手术及胃肠镜或胶囊内镜所见进行对照分析。结果肠管不同程度扩张14例;肠壁增厚14例;肠腔液体CT值为3～12 HU,平均约7.1 HU;腹腔积液并肠系膜水肿11例;肠系膜结节9例。肠淋巴干返流8例;腹膜后或胸壁淋巴管扩张、增生及返流14例。结论直接淋巴管造影术后CT可显示继发性小肠淋巴管扩张症其肠道及肠道以外的淋巴管病变范围和程度,并可同时显示其继发病的部位、范围及程度,为临床治疗和预后提供依据。Objective To explore the value of CT scanning followed direct lymphangiography （DLG） in displaying sec-ondary intestinal lymphangieetasia. Methods 14 patients with secondary intestinal lymphangiectasia from April 2007 to May 2012 were collected. The CT images followed DLG were retrospective analyzed, and compared with operation, enteros-copy or capsule endoscopy findings. Results CT showed various degrees of intestinal canal dilation in 14 cases; thicken-ing of bowel wall in 14 cases; the CT value of the intestinal cavity liquid was 3 - 12 HU（average 7.1 HU） ; ascites and mesenteric edema in 11 cases; mesenteric nodule in 9 cases. CT followed DLG showed intestinal lymphatic trunk reflux in 8 cases; retroperitoneal or pleural lymphatic dilation, hyperplasia and reflux in 14 cases. Conclusion CT followed DLG can display the range and degree of the intestinal tract, outside lesions of secondary intestinal lymphangiectasia , and can display the site, range and degree of the deuteropathy, which provides the basis for the clinical treatment and prognosis.
