FLIP panometry

FLIP panometry, or Functional Lumen Imaging Probe panometry, is a diagnostic tool used during endoscopy to assess the esophagogastric junction (EGJ) opening and esophageal contractile activity. It complements traditional motility testing by providing additional information about esophageal function. Despite its growing use, variability in procedures and interpretations has caused inconsistencies in clinical practice.

To address this, the Dallas Consensus was developed by 19 international experts using a structured Delphi process. Through three rounds of voting and discussions, the group created standardized guidelines for performing and interpreting FLIP panometry. They finalized 40 statements covering procedural techniques, data interpretation, and motility classification systems. These guidelines aim to ensure uniformity and reliability in clinical use worldwide.

FLIP results should always be interpreted alongside clinical presentation, endoscopic findings, and complementary motility studies for accurate diagnosis. A "normal" FLIP panometry strongly indicates the absence of major motor disorders, providing reassurance in diagnosis. Additionally, diminished or absent contractile responses combined with reduced EGJ opening can identify EGJ outflow obstruction, supporting the diagnosis of related disorders.

The Dallas Consensus introduced an updated motility classification system, aligning FLIP interpretations with high-resolution manometry and improving clinical outcomes. By standardizing procedures and interpretive criteria, the consensus enhances the reliability and broader application of FLIP panometry in diagnosing esophageal motility disorders. This tool is now better equipped to help clinicians evaluate and manage conditions affecting esophageal function.
