Starting with the introduction of the double-balloon enteroscope in 2001, two more techniques have been successfully developed for small bowel investigation (single-balloon enteroscopy, spiral enteroscopy). To compare the different enteroscopy systems, within this review, 68 studies were analyzed and put into context. The procedural characteristics (mean insertion depth, diagnostic yields, adverse events) were comparable for DBE, SBE or SE. The higher panenteroscopy rate in DBE might not have any clinical relevance. Therapeutic procedures, such as argon-plasma coagulation, polypectomy, dilation therapy and foreign body extraction are described with the DBE and SBE procedure. With regard to the present literature, the balloon-assisted devices as well as spiral enteroscopy technique seem to be equally suitable in clinical routine for imaging of the small bowel. The choice of the method should be based on availability, physicians' experience and clinical implications. Future randomized, controlled trials with large numbers of patients are needed to work out the subtleties of every single method.
自 2001 年双气囊内镜问世以来，又成功开发了两种用于小肠检查的技术（单气囊内镜、螺旋内镜）。为了比较不同的内镜系统，在本次综述中，分析了 68 项研究并进行了背景分析。DBE、SBE 或 SE 的操作特点（平均插入深度、诊断率、不良事件）相当。DBE 中更高的全小肠镜检查率可能没有任何临床意义。氩等离子凝固术、息肉切除术、扩张治疗和异物取出等治疗操作已在 DBE 和 SBE 中得到描述。根据目前的文献，气囊辅助设备和螺旋内镜技术在临床常规中小肠成像中似乎同样适用。方法的选择应基于可用性、医生的经验和临床意义。需要进行未来的随机、对照试验，纳入大量患者，以阐明每种方法的细微差别。
