Résumé

Abstract Background Criteria for transient lower esophageal sphincter relaxations ( TLESR s) are well‐defined for Dentsleeve manometry. As high‐resolution manometry ( HRM ) is now the gold standard to assess esophageal motility, our aim was to propose a consensus definition of TLESR s using HRM . Methods Postprandial esophageal HRM combined with impedance was performed in 10 patients with gastroesophageal reflux disease. Transient lower esophageal sphincter relaxations identification was performed by 17 experts using a Delphi process. Four investigators then characterized TLESR candidates that achieved 100% agreement ( TLESR events) and those that achieved less than 25% agreement (non‐events) after the third round. Logistic regression and decision tree analysis were used to define optimal diagnostic criteria. Key Results All diagnostic criteria were more frequently encountered in the 57 TLESR events than in the 52 non‐events. Crural diaphragm ( CD ) inhibition and LES relaxation duration >10 seconds had the highest predictive value to identify TLESR . Based on decision tree analysis, reflux on impedance, esophageal shortening, common cavity, upper esophageal sphincter relaxation without swallow and secondary peristalsis were alternate diagnostic criteria. Conclusion & Inferences Using HRM , TLESR might be defined as LES relaxation occurring in absence of swallowing, lasting more than 10 seconds and associated with CD inhibition.
