摘　　要：目的研究小肠腔内超声（ISIU）对小肠正常组织的影像学表现及对小肠病变的诊断价值。方法对2011年12月至2012年12月经胶囊内镜、胃镜、结肠镜及双气囊小肠镜检查中筛选出的50例患者，行小肠腔内超声检查，观察其正常组织结构及病变小肠的超声内镜学表现。发现小肠病变者加行经腹超声（US）及螺旋CT（SCT）检查，研究ISIU对小肠正常组织及部分病变的临床诊断价值。结果50例入选患者中，完成ISIU检查共47例，其中发现小肠病变10例。所发现病变中，ISIU诊断出全部病例，US、SCT分别诊断出1例和3例。经ISIU观察正常小肠肠壁图像可分6层，但空肠与回肠在ISIU下表现不完全相同，各有其特点。结论ISIU可提供高分辨率的正常小肠壁结构的各层次图像，并可对病变的来源及内部回声进行清晰的观察，从而有助于提高小肠疾病的诊断率。Objective To study the application of intra-luminal ultrasonography （ intra-small intestinal uhrasonography, ISIU） in demonstration of normal small intestine and diagnosis of small bowel lesions. Methods From December 2011 to December 2012, ISIU was performed in 50 patients who were screened by capsule endoscopy, gastroscopy, colonoscopy, and double-balloon enteroscopy to observe the normal tissue structures and lesions of the small intestine. Additional abdominal ultrasound （ US ） and spiral CT （SCT） were applied in patients with identified lesions in small intestine. Results ISIU was completed in 47 patients out of 50 enrolled ones. A total of 10 lesions in small intestine were detected, all of them were iden- tified by ISIU, while in which only 1 was found by US and 3 by SCT. Normal small intestinal wall demon- strated 6 layers under ISIU, with slight difference between jejunum and ileum. Conclusion ISIU provides high-resolution image of the structure at all levels of the normal small intestine, and can clearly observe lesion source and internal echo, and thus help to improve the rate of diagnosis of diseases of the small intestine.
