摘要
目的探讨经腹肠道超声诊断克罗恩病(CD)的价值。方法 对33例CD患者行经腹肠道超声检查,分析超声图像,并与内镜和(或)消化道造影结果相对照;对肠壁血流进行分级,并检测C反应蛋白(CRP)。结果 CD超声主要表现为受累肠壁不同程度增厚,呈"靶环征"、"三明治征";增厚肠壁回声层次多消失,内膜面呈平板状或"鹅卵石样改变";超声可显示深裂隙状溃疡及较大的黏膜溃疡、并能发现肠管蠕动异常。CD易并发肠管狭窄、炎性包块、肠瘘、穿孔及脓肿;受累肠壁周围出现"爬行脂肪征"。病变类型以小肠-结肠型最多见(16/33,48.48%),其次为小肠型(11/33,33.33%),结肠型占15.15%(5/33),胃-回肠型占3.03%(1/33)。受累肠壁血流分级与CRP存在显著相关(r=0.59,P<0.01),一致性中等(Kappa=0.58,P<0.01)。结论 经腹肠道超声检查在CD的诊断和随访中具有独特优势。
Objective To investigate the diagnostic value of transabdominal bowel ultrasound for Crohn disease（CD）.Methods Thirty-three patients with CD were recruited for examinations of transabdominal bowel ultrasound.The ultrasonic manifestations were analyzed and compared with the findings of gastrointestinal endoscopy and（or） all gastroenterography.Blood flow in bowel wall was classified and C-reactive protein was detected.Results The most apparent manifestation was the thickening of affected bowel wall in various degrees.＂Target sign＂,＂Sandiwich sign＂ cloud be observed.Most of the echogenic layers in thickened bowel wall were disappeared,tabulate or tubercled mucosal membrane could be observed.Ulcers and abnormal peristalsis were also observed in affected bowel wall.Abdominal complications of CD included strictures,masses,abscesses,fistulas and perforations.Besides,＂creeping fat sign＂ might be found peri-intestine.For all patients,the affected domains were classified as ileum-colon（16/33,48.48%）,small intestine（11/33,33.33%）,colon（5/33,15.15%） and stomach-ileum（1/33,3.03%）.The intensity of power Doppler signals in affected bowel wall had a good correlation with the C-reactive protein（r=0.59,P0.01）,while their diagnostic consistency was medium（Kappa=0.58,P0.01）.Conclusion High-resolution transabdominal bowel utrasound has unique advantages in diagnosis and follow-up of CD.
