Implication
Consensus update demonstrates a revised algorithmic diagnostic scheme for esophageal motility disorders, highlighting standardized metrics for high-resolution manometry.
Key Points
- To update the diagnostic criteria and algorithmic classification scheme for esophageal motility disorders using high-resolution manometry (HRM).
- Convened the International HRM Working Group to incorporate clinical experience and interval publications published since the 2011 classification.
- Established a hierarchical diagnostic scheme sequentially prioritizing esophagogastric junction (EGJ) outflow disorders, major peristaltic disorders, and minor peristaltic disorders.
- Retained key metrics—integrated relaxation pressure, distal contractile integral (DCI), and distal latency—with increased diagnostic reliance on DCI for hyper- and hypocontractility.
- Added criteria for resting EGJ morphology, fragmented contractions, and ineffective esophageal motility, while removing contractile front velocity and small contour breaks.
