AIM: Consecutive monitoring of intragastric pH using the Bravo(R) capsule.METHODS: We put threads through a Bravo(R) 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.RESULTS: 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.CONCLUSION: Clipping a Bravo(R) 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.
