目的 确定是否可以通过灰阶和彩色多普勒超声检查 (US) 区分儿童肠壁增厚的血管、缺血和炎症原因。 材料和方法 37 名患有急性肠病的儿童接受了分级加压超声检查。评估了肠壁厚度、壁回声纹理、肠受累位置以及彩色多普勒血流的存在。诊断分为炎症 (n = 25)、血管炎 (n = 7) 或缺血 (n = 5)，并通过结肠镜检查和活检、粪便培养分析、手术和皮肤活检的结果以及临床和实验室数据的结合得到证实。 结果 患者年龄 (P = .0022)、肠壁厚度 (P = .0001) 和彩色多普勒血流 (P = .0013) 与疾病类型在统计学上显着相关。壁增厚和缺乏可见的彩色多普勒血流提示缺血。老年患者年龄和可见彩色多普勒血流提示炎症，而年轻患者年龄和可见彩色多普勒血流提示血管炎。缺血性患者与血管壁增厚患者的肠道疾病位置差异具有统计学意义 (P = .0185)。疾病类型和壁分层之间没有发现差异。 结论 灰度和彩色多普勒血流超声可以帮助区分缺血性、血管性和炎症性肠壁增厚。
PURPOSE To determine whether vascular, ischemic, and inflammatory causes of bowel wall thickening in children can be differentiated at gray-scale and color Doppler ultrasonography (US). MATERIALS AND METHODS Thirty-seven children with acute bowel disease underwent graded compression US. Findings of bowel wall thickness, wall echotexture, location of bowel involvement, and presence of color Doppler flow were evaluated. Diagnoses were classified as inflammation (n = 25), vasculitis (n = 7), or ischemia (n = 5) and were confirmed with findings from colonoscopy and biopsy, stool culture analysis, surgery, and cutaneous biopsy, and with a combination of clinical and laboratory data. RESULTS Patient age (P = .0022), bowel wall thickness (P = .0001), and color Doppler flow (P = .0013) were statistically significantly related to disease type. Wall thickening and absence of visible color Doppler flow suggested ischemia. Older patient age and visible color Doppler flow suggested inflammation, whereas younger patient age and visible color flow suggested vasculitis. Difference in location of bowel disease in patients with ischemic versus those with vascular wall thickening was statistically significant (P = .0185). No difference was found between disease type and wall stratification. CONCLUSION Gray-scale and color Doppler flow US can aid in differentiating ischemic, vascular, and inflammatory bowel wall thickening.
