Consecutive monitoring of intragastric pH using the Bravo capsule.
We put threads through a Bravo capsule and then affixed it to the gastric wall by endoscopic hemoclipping in seven subjects. Study data were uploaded to a computer via Datalink every 48 h. In this way, repeated monitoring of intragastric pH was undertaken.
All subjects were able to monitor gastric pH over a 1-wk period, and five for > 2 wk. No complications were encountered during the monitoring. After pH monitoring, we safely retrieved the capsule endoscopically.
Clipping a Bravo capsule onto the gastric wall enabled long-term intragastric pH monitoring. This is a methodological report of pH monitoring over a period of > 2 wk.
使用Bravo胶囊连续监测胃内pH值。
我们将线穿过Bravo胶囊,然后通过内镜下血管夹将其固定在7名受试者的胃壁上。研究数据每48小时通过数据链路上传至计算机。通过这种方式,对胃内pH值进行了重复监测。
所有受试者均能够在1周内监测胃pH值,5名受试者监测时间超过2周。监测期间未出现并发症。pH值监测结束后,我们通过内镜安全地取出了胶囊。
将Bravo胶囊夹在胃壁上能够实现胃内pH值的长期监测。这是一篇关于超过2周时间pH值监测的方法学报告。
