LINX© Reflux Management System Main Content
What is LINX?
LINX is a small, flexible band of magnets enclosed in titanium beads. The system is implanted around the weak lower esophageal sphincter (LES), which is located just above the stomach. The magnetic attraction between the beads keeps the weak esophageal sphincter closed to help prevent reflux. Swallowing forces the beads to temporarily separate, allowing food and liquid to pass into the stomach.
Who can benefit from LINX?
LINX is now the first choice for the majority of patients who need surgery to correct GERD, even those with a large hiatal hernia or who need a revision from an earlier reflux operation.
What diagnostic tests are used?
Of course, some routine testing is needed before a final decision about the use of LINX can be made. Standard diagnostic screenings typically include:
- Upper Endoscopy (EGD): using an endoscope (a long, flexible tube with a small light and camera at the end), doctors look down your mouth, throat, esophagus, stomach, and into your duodenum.
- Esophageal pH Test (48-hour Bravo): by placing a pH capsule to the wall of your esophagus, this test monitors whether acid is coming back into the esophagus.
- Video Esophagram (VEG) for Dysmotility: a barium swallow test, followed by a swallow of a piece of a bagel, followed by a swallow of a piece of marshmallow.
Additional tests may include:
- High Resolution Manometry (HRM): to measure the pressure in your esophagus a thin, small computerized tube, after you are numbed, is placed from your nose to your lower-esophageal sphincter while 10 swallows of water are evaluated in a resting position.
How long is the procedure?
LINX is implanted laparoscopically in a minimally invasive procedure that typically takes less than one hour. Patients generally go home within one day.
What kind of results can I expect?
According to LINX study results published in the New England Journal of Medicine, results showed:
- 91% of patients achieved freedom from GERD medication
- 92% of patients reported significant symptom improvement
- 100% of patients eliminated severe regurgitation
- 99% of patients eliminated daily sleep disruption due to heartburn
- 94% of patients were satisfied with their overall condition
How long has LINX Been used?
LINX has been used as a treatment for GERD for more than 10 years, with the first U.S. implants being done in 2008-2009 as part research needed to gain FDA approval. It was approved by the FDA in March of 2012. More detail about the research that supports the safety and effectiveness of the LINX device and procedure can be found on the LINX website.
