摘要
目的评估多层螺旋CT小肠增强造影(MSCTE)在诊断炎症性肠病(IBD)中的价值。方法回顾性分析45例IBD患者的病史资料,总结其MSCTE的影像学表现特点,并与常规结肠镜检查结果进行对比分析。结果 45例IBD患者中克罗恩病(CD)29例,溃疡性结肠炎(UC)16例。CD患者中,25例MSCTE有阳性发现,最常见的为肠道管壁增厚(21例,72.4%)及肠周间隙模糊伴渗出(9例,31.0%);发现病变的部位以回盲部及末端回肠最多(44.8%);MSCTE表现与结肠镜检查结果对比,前者发现的病变部位与后者完全吻合的有15例(51.7%),前者发现空肠病变部位而后者无法发现的有10例(34.5%)。UC患者中,只有6例MSCTE有阳性发现,其中肠道管壁增厚亦最多见(5例,31.3%);发现病变的部位以结肠居多(31.3%);MSCTE表现与结肠镜检查结果对比,前者发现的病变部位与后者完全吻合的只有5例(31.3%),而后者发现病变部位而前者未发现的却有11例(68.7%)。结论多层螺旋CT小肠增强造影对于CD的诊断价值较高。可通过发现小肠可能的病灶来弥补常规结肠镜检查的不足。MSCTE对于UC的诊断价值有限。
Objective To evaluate the value of multi- slice CT enteroclysis （MSCTE） in the diagnosis of inflammatory bowel disease（IBD）. Methods Retrospectively analyze the case history of 45 patients with IBD, summarize the imaging fea- tures of MSCTE and compare to the eolonoscopy results. Results 45 IBD patients included 29 cases of Crohn＇ s disease（CD） and 16 cases of ulcerative colitis（UC）. Among CD patients ,positive features were found in 25 cases ,of which the most common was thickened bowel wall （21 cases ,72.4% ） and blur of paraintestinal space （9 cases ,31.0% ） ;ileocecal junction and terminal ileum accounted for 44.8% of the discovered diseased regions;by comparison of MSCTE features and colonoscopy results, the former was consistent with the latter in 15 cases, however, the former showed positive but the latter showed negative in 10 cases. Among UC patients, positive features were only found in 6 cases, of which the most common was also thickened bowel wall （5 cases,31.3% ） ; colon accounted for most of the discovered diseased regions ; by comparison of MSCTE features and colonoscopy results, the former was consistent with the latter only in 5 cases, however, the latter showed positive but the former showed nega- tive in 11 cases. Conclusion MSCTE is more valuable to the diagnosis of CD than that of UC. MSCTE can detect the diseased regions occurring in small intestine that cannot be discovered by eolonoscopy.
