摘要
Capsule endoscopy has revoluzionized the study of the small bowel by providing a reliable method to evaluate, endoscopically, the entire small bowel. In the last six years several papers have been published exploring the possible role of this examination in different clinical conditions. At the present time capsule endoscopy is generally recommended as a third examination, after negative bidirectional endoscopy, in patients with obscure gastrointestinal bleeding. A growing body of evidence suggests also an important role for this examination in other clinical conditions such as Crohn＇s disease, celiac disease, small bowel polyposis syndromes or small bowel tumors. The main complication of this examination is the retention of the device at the site of a previously unknown small bowel stricture. However there are also some other open issues mainly due to technical limitations of this tool （which is not driven from remote control, is unable to take biopsies, to insufflate air, to suck fluids or debris and sometimes to correctly size and locate lesions）.The recently developed double balloon enteroscope, owing to its capability to explore a large part of the small bowel and to take targeted biopsies, although being invasive and time consuming, can overcome some limitations of capsule endoscopy. At the present time, in the majority of clinical conditions （i.e. obscure GI bleeding）, the winning strategy seems to be to couple these two techniques to explore the small bowel in a painless, safe and complete way （with capsule endoscopy） and to define and treat the lesions identified （with double balloon enteroscopy）.
囊内视镜检查法有 revoluzionized 由提供一个可靠方法评估的小肠的学习，内视镜的联盟者，全部小肠。在最后六年里，几份报纸被出版了处于不同临床的条件探索这考试的可能的角色。在现在的时间囊，内视镜检查法通常被推荐为第三考试，在否定双向内视镜检查法以后，在有阴暗胃肠的流血的病人。证据的成长身体也处于象 Crohn 的疾病，乳糜泻，小肠息肉病症候群或小肠肿瘤那样的另外的临床的条件为这考试建议一个重要角色。这考试的主要复杂并发症是在以前未知的小肠苛评的地点的设备的保留。然而，也由于这个工具的技术限制主要有一些另外的开的问题(它没从遥控被驾驶，是不能的拿活体检视到 insufflate 空气，正确地缩放并且定位损害到 suck 液体或碎片并且到有时) 。最近发达的双汽球肠脓毒病，尽管侵略、耗时，由于它的能力指向了活体检视探索小肠的大部分并且拿，能克服囊内视镜检查法的一些限制。在现在预定，在临床的条件的多数(即阴暗官方补给的流血)，赢的策略似乎是联合这二种技术探索小肠在一无痛苦，安全、完全的方法(与囊内视镜检查法)并且识别了定义并且对待损害(与两倍汽球肠寄生物)。
