LINX® Safety and Efficacy Rivals Laparoscopic Nissen Fundoplication

Torax Medical, Inc. points us at new retrospective data showing its clever LINX device to be as effective as Laparoscopic Nissen Fundoplication (LNF) in controlling reflux but with less side effects.


Torax Medical’s LINX has been featured on our pages before. It is a small implant comprised of interlinked titanium beads with magnetic cores. The magnetic attraction between the beads augments the existing esophageal sphincter’s barrier function to prevent reflux. The device is implanted using a standard minimally invasive laparoscopic procedure and is an alternative to the more anatomically disruptive fundoplication, commonly used in surgical anti-reflux procedures. The LINX Reflux Management System is indicated for those patients diagnosed with gastro-esophageal reflux disease (GERD) as defined by abnormal pH testing, and who continue to have chronic GERD symptoms despite maximum medical therapy for the treatment of reflux.

The new study comes from the University of Southern California, Keck Medical Center, a leading institution in the diagnosis and treatment of GERD. The retrospective study led by Dr. John C. Lipham, compared the LINX® Reflux Management System (LINX) to the standard of care, Laparoscopic Nissen Fundoplication (LNF) in similar patient populations. When compared to LNF for side effects, LINX patients reported less severe gas and bloating, while maintaining the ability to belch and vomit.

Investigator comments

John C. Lipham, MD Chief, Division of Upper GI and General Surgery, Associate Professor of Clinical Surgery, Keck School of Medicine of USC said, “This is the first propensity matched study comparing LINX to LNF assessing quality of life, proton-pump inhibitor (PPI) use, satisfaction and complications. This study validates the LINX results shown in other studies and substantiates that LINX is as effective as LNF in controlling reflux. It further supports the use of LINX as a first line therapy in patients who are failing drugs to control their reflux.” The study results were published in the Journal of the American College of Surgeons (
