Achalasia Treatment Response: New and Improved Metrics?

A novel metric, bolus flow time, might be better than current high-resolution manometry metrics.

As symptoms do not always correlate with objective measures in achalasia (as with many esophageal diseases), improved objective metrics are sought for postintervention assessment of treatment success. In the current study, researchers tested the accuracy of two novel metrics — bolus flow time (BFT) and esophagogastric contractile interval (EGCI) — and two established metrics — esophagogastric junction pressure (EGJP) and integrated relaxation pressure (IRP) — in assessing clinical outcomes after achalasia treatment. BFT incorporates simultaneous video fluoroscopy with high-resolution manometry (HRM) to evaluate flow across the esophagogastric junction (EGJ). The EGCI assesses EGJ barrier function using both an intragastric pressure referenc…
