In 1997, we devised a method of enteroscopy that uses 2 balloons, 1 balloon attached to the tip of the endoscope and the other balloon attached to the distal end of a soft overtube. We reported that endoscopic observation of the entire small intestine was possible with this method by using an endoscope of 200-cm working length. This double-balloon endoscopy system now is available commercially. We have experience with more than 250 cases of enteroscopy since September 2000 using the double-balloon endoscope including our experience with the prototype. Recently, a new therapeutic type of double-balloon endoscope was developed. The new type has an accessory channel of 2.8 mm, which is bigger than the 2.2-mm accessory channel of the standard double-balloon endoscope.
1997年，我们设计了一种小肠镜检查方法，该方法使用两个气囊，一个气囊附着在内窥镜尖端，另一个气囊附着在软外套管的远端。我们报告称，使用工作长度为200厘米的内窥镜，通过这种方法可以对整个小肠进行内镜观察。这种双气囊内镜系统现已商业化。自2000年9月以来，我们使用双气囊内窥镜（包括我们使用原型的经验）进行了250多例小肠镜检查。最近，一种新型治疗型双气囊内窥镜被开发出来。新型号有一个2.8毫米的附件通道，比标准双气囊内窥镜2.2毫米的附件通道大。
