Double-balloon enteroscopy (DBE) is a useful and epoch-making technique for small-bowel diseases. The single-balloon enteroscope (SBE) is a new instrument introduced by Olympus.
To evaluate a prototype of the SBE.
A prospective case series.
Kyoto Second Red Cross Hospital, between April 2006 and July 2007.
We used the SBE system to perform 37 enteroscopic examinations on 27 patients, including 22 oral and 15 anal approaches.
The rate of whole small-bowel visualization, mean time necessary for the investigation, discovery rate of lesions, and complications.
We observed the entire small intestine in 1 of 8 cases (12.5%) that we examined. The mean (+/-SD) time necessary for the oral approach was 83 +/- 38 minutes and that for the anal approach was 90 +/- 32 minutes. The preparation time was less than 5 minutes in both approaches. Small-intestinal lesions were detected in 11 of the 27 patients (40.7%). Perforation occurred in one case as a complication, but the injury healed without surgical intervention.
This was a single-center study.
Use of the SBE system in the endoscopic study of the small intestine makes it possible to observe the entire small intestine and to diagnose lesions; thus, the SBE system is a useful instrument for small-bowel diseases. However, the rate of whole small-bowel visualization was inferior to the DBE system.
双气囊小肠镜检查（DBE）是用于小肠疾病的一种有用且具有划时代意义的技术。单气囊小肠镜（SBE）是奥林巴斯推出的一种新器械。
评估SBE的一个原型。
前瞻性病例系列研究。
京都第二红十字医院，2006年4月至2007年7月。
我们使用SBE系统对27例患者进行了37次小肠镜检查，包括22次经口途径和15次经肛途径。
全小肠可视化率、检查所需平均时间、病变发现率及并发症。
在我们检查的8例患者中，有1例（12.5%）观察到了整个小肠。经口途径所需平均（±标准差）时间为83±38分钟，经肛途径为90±32分钟。两种途径的准备时间均少于5分钟。27例患者中有11例（40.7%）检测到小肠病变。有1例发生穿孔并发症，但损伤未经手术干预自行愈合。
这是一项单中心研究。
在小肠内镜检查中使用SBE系统能够观察整个小肠并诊断病变；因此，SBE系统是用于小肠疾病的一种有用器械。然而，全小肠可视化率低于DBE系统。
