小肠Crohn病的螺旋CT诊断价值

摘要

目的:探讨螺旋CT对小肠Crohn病的诊断价值.方法:回顾性分析10例经病理证实的小肠Crohn病螺旋CT表现,将螺旋CT表现与小肠造影进行比较,分析其影像学特点.结果:10例患者中小肠造影发现6例异常,表现为肠腔节段性狭窄、肠粘膜破坏及瘘管形成.10例CT表现为多节段肠壁及肠系膜增厚,肠壁不同程度强化,3例出现肠瘘,2例出现腹腔脓肿及肠梗阻,肠系膜淋巴结肿大3例.结论:螺旋CT对小肠Crohn病的部位及性质诊断较小肠造影更具有优势,同时能更多观察肠内外病变,并能判断临床治疗效果,有可能成为小肠Crohn病的主要影像学诊断方法.%Objective:To investigate the value of spiral CT in the diagnosis of small-bowel Crohn disease. Methods:Spiral CT manifestation of 10 patients with small-bowel Crohn disease pathologically proved were analysed retrospectively, and compared with the small bowel radiography, the imaging feature of spiral CT in smali-bowel Crohn disease were analysed.Resujts: Of the 10 patients, there were abnormal manifestations in 6 patients on small bowel radiography, they were segmental luminal narrowing, mucosal destroy and fistula forming. On spiral CT, mural and mesenteric thickening and mucosal hyperenhancement in 10 patients, fistula in 3 patients, abdominal cavity abscess and small bowel obstruction in 2 patients, bowel mesenteric lymphadenectasis in 3 patients. Conclusion:Spiral CT can provide an advantage of not only showing the location and character of small bowel Crohn disease compared with small bowel radiography, but also changes out of and in the luminal of small bowel, the clinical therapeutic effect, and may be a main imaging method in diagnosis of small bowel Crohn disease.
