Double balloon endoscopy (DBE) is an emerging modality for complete endoscopic visualization of the small intestine. Although the most common indication of DBE is currently for evaluation of obscure GI bleeding or suspected small-bowel pathology, the unique technical features of the double balloon endoscope have led to its newer uses.
To evaluate the utility of DBE by the retrograde approach to perform a complete evaluation of the colon.
Sixteen patients in whom examination of the entire colon could not be achieved with conventional colonoscopy.
Using DBE by the retrograde approach, we achieved a high success rate of complete endoscopic examination of the entire colon, and we were also able to perform appropriate therapeutic interventions. The procedures were well tolerated by the patients and could be performed with the patient under conscious sedation and without the use of fluoroscopy.
This study comprised a small number of patients and there was no control group.
Anecdotal data suggest that other areas in which DBE technology may be potentially helpful are ERCP in patients with surgically altered anatomy, and endoscopic evaluation of the bypassed segment of the upper GI tract in patients who have undergone bariatric surgery, but such applications will require the development of appropriate accessories and substantial technical modification to currently available instruments.
双气囊小肠镜检查（DBE）是一种用于小肠完整内镜可视化的新兴技术。尽管DBE目前最常见的适应证是评估不明原因的胃肠道出血或疑似小肠病变，但双气囊内镜独特的技术特点使其有了新的用途。
评估逆行法DBE对结肠进行完整评估的效用。
16例无法通过传统结肠镜检查完成全结肠检查的患者。
采用逆行法DBE，我们实现了全结肠完整内镜检查的高成功率，并且还能够进行适当的治疗干预。这些操作患者耐受性良好，可以在患者清醒镇静且不使用荧光透视的情况下进行。
本研究患者数量较少且无对照组。
轶事数据表明，DBE技术可能有潜在帮助的其他领域包括解剖结构改变的患者的内镜逆行胰胆管造影（ERCP），以及接受减肥手术患者对上消化道旁路节段的内镜评估，但此类应用需要开发合适的附件并对现有器械进行大量技术改进。
