摘　　要：小肠壁增厚是多种小肠疾病的一种常见病理表现，包括肿瘤性和非肿瘤性。常规肠镜、胶囊内镜、x线钡餐造影和小肠超声检查对小肠病变的诊断有一定困难，病变检出阳性率低、漏诊率高。而小肠CT仿真内镜检查因肠道准备复杂，对于症状隐匿的小肠疾病无法普及应用。本研究回顾性分析2009年12月至2011年12月我院收治的2672例小肠壁增厚患者的临床资料，总结小肠疾病的常规CT检查特征，旨在提高小肠疾病的阳性检出率。Small bowel wall thickening is one of the presentations of small bowel diseases. Conventional diagnostic methods, such as enteroscopy, barium-contrast radiography, X-ray, capsule endoscopy, and ultrasonograhy have disadvantages of low positive rate and high misdiagnosis rate. From December 2009 to December 2011, 2672 patients with small bowel wall thickening were admitted to the Southwest Hospital. The loca- tion, range, degree, attenuation, enhancement feature and asso- ciated perienteric abnormalities of thickened bowel wall were studied. Differential diagnosis of tumorous and non-tumorous small bowel wall thickening, malignant and benign tumorous small bowel wall thickening, and different diseases caused non- tumorous small bowel wall thickening were carried out in the study. Etiopathogenesis of small bowel wall thickening can be inferred by computed tomography, and multi-slice computed tomography plays an important role in the differential diagnosis.
