A Standardized Approach to Performing and Interpreting Functional Lumen Imaging Probe Panometry for Esophageal...

Area of Science:

• Gastroenterology
• Esophageal Physiology
• Diagnostic Endoscopy

Background:

• Functional Lumen Imaging Probe (FLIP) panometry assesses esophagogastric junction opening and esophageal motility.
• It is increasingly used in comprehensive esophageal motility assessments.
• Standardization is needed for consistent interpretation and updated classification.

Purpose of the Study:

• To establish a standardized approach and vocabulary for FLIP panometry procedure and interpretation.
• To update the esophageal motility classification scheme based on expert consensus.

Main Methods:

• A modified Delphi consensus process involving 19 FLIP panometry experts.
• Multiple rounds of voting on statement appropriateness (1-9 scale) and face-to-face discussions.
• Selection of 40 statements for the Dallas Consensus, focusing on protocol, interpretation, and classification.

Main Results:

• The Dallas Consensus includes statements on FLIP panometry protocol and interpretation.
• Key findings emphasize interpreting FLIP panometry in clinical context (100% agreement).
• A normal FLIP panometry classification suggests major motor disorders are unlikely (94% agreement), and nonspastic EGJ outflow obstruction is supported by diminished contractility with reduced opening (94% agreement).

Conclusions:

• The standardized approach facilitates broader clinical use of FLIP panometry.
• The Dallas Consensus provides a framework for consistent performance and interpretation.
• This standardization aims to improve the diagnosis and management of esophageal motility disorders.
