Conclusion
In this paper, we reported two very rare complications of HEMII-pH, consisting of probe movements and node in the esophagus. These complications may affect the tracing analysis if the HEMII-pH testing is realized for GERD. For LPR, the impact is lower because the LPR diagnosis is mainly based on the occurrence of hypopharyngeal reflux episodes.
