EndoFLIPEndoFLIP is a novel diagnostic tool for evaluating esophageal motility and distensibility, especially in cases where high-resolution manometry (HRM) results are inconclusive. Unlike HRM, which measures pressure at contact points within the esophagus, EndoFLIP uses a balloon catheter and impedance planimetry to assess the esophageal lumen’s cross-sectional area (CSA) and pressure in real-time. This allows for the evaluation of esophagogastric junction (EGJ) distensibility and esophageal contraction patterns through a procedure called FLIP panometryFLIP panometry. The examination is typically performed during sedated endoscopy and includes stepwise balloon inflation while monitoring the EGJ distensibility index (EGJ-DI) and contractile responses. The FLIP Panometry Classification system combines EGJ opening and contraction pattern analysis to categorize motility disorders. FLIP panometry provides a well-tolerated method that can complement, or in some cases be an alternative to HRM, for evaluating esophageal motility disorders.

摘要

EndoFLIPEndoFLIP is a novel diagnostic tool for evaluating esophageal motility and distensibility, especially in cases where high-resolution manometry (HRM) results are inconclusive. Unlike HRM, which measures pressure at contact points within the esophagus, EndoFLIP uses a balloon catheter and impedance planimetry to assess the esophageal lumen’s cross-sectional area (CSA) and pressure in real-time. This allows for the evaluation of esophagogastric junction (EGJ) distensibility and esophageal contraction patterns through a procedure called FLIP panometryFLIP panometry. The examination is typically performed during sedated endoscopy and includes stepwise balloon inflation while monitoring the EGJ distensibility index (EGJ-DI) and contractile responses. The FLIP Panometry Classification system combines EGJ opening and contraction pattern analysis to categorize motility disorders. FLIP panometry provides a well-tolerated method that can complement, or in some cases be an alternative to HRM, for evaluating esophageal motility disorders.
