Zusammenfassung:Abstract Background High-resolution esophageal manometry (HRM) is the gold standard for studying esophageal motility disorders but isn't universally available, and it's also reported as invasive and uncomfortable. The EndoFLIP system offers a dynamic evaluation of the esophagogastric junction (EGJ), crucial for patients with inconclusive HRM or undergoing endoscopic or surgical therapy such as myotomy or fundoplication. EndoFLIP is a practical tool in patients with dysphagia with normal upper endoscopy, allowing diagnostic assessment during the same procedure, and better selecting patients for subsequent HRM. Methods We conducted a retrospective study where we analyzed EndoFLIP procedures performed at a tertiary center from January 2022 to February 2024, for multiple indications, including characterization of findings on HRM, primary investigation of patients with dysphagia undergoing diagnostic upper endoscopy, motility study in patients intolerant to HRM, and post-therapeutic endoscopic/surgical assessment. Results Sixty-nine patients submitted to EndoFLIP procedures were included (39.1% male; 60.9% female) with a median age of 62 years. The primary indication was dysphagia, with 17.3% of patients being intolerant or referred with inconclusive HRM. EndoFLIP enabled diagnosis in all patients, even with an inconclusive HRM. Endoflip was performed on patients with treated achalasia with recurrence of dysphagia (16%), of which 55% exhibited reduced distensibility of EGJ. The evidence of reduced distensibility allowed patient selection for further treatment. Seven patients underwent EndoFLIP to characterize EGJOO. Comparing paired data from HRM and EndoFLIP, overall concordance was only 47,1%. Endoflip showed a large discordance for the EGJOO group, with 50% having normal findings and 20% confirming EGJOO. 43,8% of patients diagnosed with EGJOO confirmed by EndoFLIP underwent endoscopic therapy during the same procedure, allowing the diagnosis and treatment at the same time. Four patients with gastroesophageal reflux disease, intolerant to HRM and proposed for Nissen fundoplication, underwent EndoFLIP for EGJ and esophageal motility evaluation. Currently, they are proposed for surgery due to the normal findings on EndoFLIP. Conclusion The use of EndoFLIP in evaluating esophageal motility disorders presents a paradigm shift, overcoming the limitations of traditional methods like HRM. Our retrospective study demonstrates its pivotal role in diagnosing and manag
