The computed tomographic (CT) scans of 22 children with small bowel disease and those of 110 children with no small bowel disease were analyzed by two observers who were blinded with respect to clinical history and final diagnoses in order to determine which CT findings reliably indicated neoplastic, inflammatory, or noninflammatory processes. Bowel-wall thickening was the most reliable sign of disease. Five of six patients (83%) with bowel-wall thickness greater than 1 cm had neoplastic disease. Nine of ten patients (90%) with bowel-wall thickness between 3 mm and 1 cm had inflammatory disease, while four of six patients (66%) with wall thickness less than 1 cm and increased attenuation of mesenteric fat or an increase in the number of mesenteric vessels had noninflammatory edema. The presence of mesenteric masses was not a helpful sign for differentiating various disease processes. The results of this retrospective study suggest that the identification and classification of small bowel disease in children is possible from the objective analysis of CT findings.
两名观察者对22例患有小肠疾病的儿童和110例无小肠疾病的儿童的计算机断层扫描（CT）图像进行了分析，这两名观察者对临床病史和最终诊断不知情，以确定哪些CT表现能够可靠地提示肿瘤性、炎症性或非炎症性病变。肠壁增厚是最可靠的疾病征象。肠壁厚度大于1 cm的6例患者中有5例（83%）患有肿瘤性疾病。肠壁厚度在3 mm至1 cm之间的10例患者中有9例（90%）患有炎症性疾病，而肠壁厚度小于1 cm且肠系膜脂肪衰减增加或肠系膜血管数量增多的6例患者中有4例（66%）患有非炎症性水肿。肠系膜肿块的存在对区分各种疾病过程并无帮助。这项回顾性研究的结果表明，通过对CT表现进行客观分析，有可能对儿童小肠疾病进行识别和分类。
