Background Three previous studies from the same institution have reported that transoral incisionless fundoplication (TIF) with the EsophyX device is effective for creating a continent gastroesophageal valve and for good functional results as measured only by pH-metry in patients with gastroesophageal reflux disease (GERD). The objective of the present study was to evaluate the effect of TIF on symptoms, use of proton pump inhibitors (PPI), esophageal motility, and pH-impedance in patients with symptomatic GERD. Methods Twenty consecutive patients were enrolled to complete the GERD-HRQL and GERD-QUAL question-naires while on and off PPI. They were also examined by upper gastrointestinal (GI) endoscopy to determine Hill grade and Jobe length of the gastroesophageal valve, and to check for hiatal hernia and esophagitis, esophageal manometry, and pH-impedance before and 6 months after TIF. Results Six months after TIF, the GERD-HRLQ and GERD-QUAL scores off-PPI therapy and the number of total and acid pH-impedance refluxes were significantly reduced (p <0.05). The PPI had been completely stopped in 55% of the patient and was reduced in 22% of the patients. Conclusions At 6-month follow-up, TIF performed using the EsophyX device reduces symptoms and pH-impedance refluxes, allowing interruption or reduction of PPI use in 78% of patients with GERD.
