小肠是消化道中最长的一段,位于消化管中央,常规检查手段难以到达或者获得理想效果,传统的胃肠镜检查仅能对一小部分小肠黏膜进行直视检查,而其他影像学检查如小肠气钡造影、核素扫描、CT及磁共振成像(MRI)等对小肠疾病的诊断价值也比较有限。因此,长期以来小肠一直是消化道检查的盲区,小肠疾病也由于检查手段的限制而难以得到正确诊断,导致大量小肠疾病患者的长期误诊和漏诊,不仅浪费了大量的医疗资源,而且更重要的是贻误了小肠疾病治疗的最佳时机。
Small intestine is the longest segment of the digestive tract, located in the center of the digestive tract, the conventional means of inspection is difficult to reach or obtain the desired effect, the traditional gastrointestinal endoscopic examination of only a small part of the small intestine mucosa direct inspection, and other imaging studies such as small intestine Gastrointestinal barium imaging, radionuclide scanning, CT and magnetic resonance imaging (MRI) and other diagnostic value of small intestine disease is relatively limited. Therefore, the small intestine has long been a blind spot for digestive tract tests. Small intestine diseases are also difficult to be correctly diagnosed due to the limitation of examination methods. As a result, long-term misdiagnosis and missed diagnosis of large numbers of small intestinal diseases not only waste a large amount of medical resources but also more important Is the best time to delay the treatment of intestinal diseases.
