Summary

This study looked at whether a detailed swallowing test (high-resolution manometry) can find the cause of swallowing problems when a standard scope shows nothing wrong. 247 adults with unexplained trouble swallowing took part. The goal was to see if this test gives a clearer diagnosis and is more comfortable than the older method.
