Since its inception in 2003, EndoGastric Solutions (EGS) has been dedicated to the continued pursuit of robust clinical research evidence supporting the management of GERD symptoms and the TIF procedure with the EsophyX device®. Currently, more than 70 peer-reviewed papers from over 50 centers have been published documenting consistent outcomes on over 1,100 unique TIF patients.
The following are ongoing and completed studies:

Future Clinical Trials
EndoGastric Solutions continues to support clinical trials and prospective research. Our mission is to support health care professionals, key opinion leaders, regulatory agencies, payers, professional groups, physicians and patients with scientific information and education that meets or exceeds quality standards. EGS believes that the current and anticipated publications on the TIF procedure as well as the future studies we are planning will ultimately assist physicians and patients to choose the most appropriate therapy. EGS is working to expand the current body of TIF clinical publications by initiating the following studies:
- Partnering with commercial payers to assess and model the direct and indirect cost impact of traditional treatment modalities for GERD vs. TIF procedures
- Investigator initiated trials on specific GERD symptom domains following TIF procedures
- Internal R&D studies
