Double-balloon endoscopy has been available for investigation of the small bowel since 2001, concomitantly with capsule endoscopy. Beyond established indications, endoscopic examination of the small bowel is currently performed in many clinical conditions involving the small bowel, which were under investigated in the past. Biopsies of lesions observed by capsule endoscopy or balloon enteroscopy can be taken and the lesions can sometimes be treated during a balloon Endoscopic procedure. Double-balloon endoscopy can be used in patients when conventional endoscopy was incomplete. The main applications of double-balloon endoscopy are the examination of patients with a surgically modified gastrointestinal tract and colonoscopy after a previously failed attempt to reach the cecum. In the latter indication, using a dedicated double-balloon colonoscope, the success rate of cecal intubation may be nearly 100%.
自2001年起，双气囊内镜已可用于小肠检查，与胶囊内镜同时出现。除了既定的适应症外，目前在许多涉及小肠的临床情况下都会进行小肠内镜检查，这些情况在过去并未得到充分研究。可以对胶囊内镜或气囊小肠镜观察到的病变进行活检，有时还可以在气囊内镜检查过程中对病变进行治疗。当传统内镜检查不完整时，双气囊内镜可用于患者。双气囊内镜的主要应用是检查胃肠道手术改道的患者，以及在先前尝试到达盲肠失败后进行结肠镜检查。在后一种适应症中，使用专用的双气囊结肠镜，盲肠插管的成功率可能接近100%。
