Observational Registry of Transoral Incisionless Fundoplication (TIF) for Gastroesophageal Reflux Disease (GERD)

This observational registry aims to: 1) record the TIF interventions in patients with esophageal or extra-esophageal symptoms; 2) to monitor the therapy response through the clinical experience in terms of effect on the use and dosage of proton pump inhibitors (PPIs) and on the GERD-Health Related Quality of Life (HRQL) and Reflux Symptom Index (RSI) questionnaires scores; 3) to characterize the treated patients population and the predictive factors of TIF success, identifying the subpopulation who may effectively benefit from TIF.
