Esophageal motility classification can be established at the time of endoscopy: a study evaluating real-time functional luminal imaging probe panometry - 20/11/19
Abstract |
Background and Aims |
A novel device that provides real-time depiction of functional luminal image probe (FLIP) panometry (ie, esophagogastric junction [EGJ] distensibility and distension-induced contractility) was evaluated. We aimed to compare real-time FLIP panometry interpretation at the time of sedated endoscopy with high-resolution manometry (HRM) in evaluating esophageal motility.
Methods |
Forty consecutive patients (aged 24-81 years; 60% women) referred for endoscopy with a plan for future HRM from 2 centers were prospectively evaluated with real-time FLIP panometry during sedated upper endoscopy. The EGJ distensibility index and contractility profile were applied to derive a FLIP panometry classification at the time of endoscopy and again (post-hoc) using a customized program. HRM was classified according to the Chicago classification.
Results |
Real-time FLIP panometry motility classification was abnormal in 29 patients (73%), 19 (66%) of whom had a subsequent major motility disorder on HRM. All 9 patients with an HRM diagnosis of achalasia had abnormal real-time FLIP panometry classifications. Eleven patients (33%) had normal motility on real-time FLIP panometry and 8 (73%) had a subsequent HRM without a major motility disorder. There was excellent agreement (κ = .939) between real-time and post-hoc FLIP panometry interpretation of abnormal motility.
Conclusions |
This prospective, multicentered study demonstrated that real-time FLIP panometry could detect abnormal esophageal motility, including achalasia, at the endoscopic encounter. Additionally, normal motility on FLIP panometry was predictive of a benign HRM. Thus, real-time FLIP panometry incorporated with endoscopy appears to provide a suitable and well-tolerated point-of-care esophageal motility assessment.
