For those in whom acid-suppression therapy is no longer sufficient to control their symptoms, the only option remaining is surgical which, until now, effectively meant a Nissen Fundoplication. The Nissen procedure is technically complex, requires a major alteration to the anatomy of the stomach and has variable success rates. Accordingly, it tends to be reserved for those patients who have reached the point where there is really no other alternative.
The LINX™ System fulfils a treatment gap between those whose symptoms are not well controlled on drug treatment, but not severe enough to warrant a Nissen procedure which is not only complex, but is also irreversible.
How Does the LINX™ System Work?
The LINX™ System is designed to prevent gastric reflux by augmenting the lower oesophageal sphincter (LES) – the body’s natural anti-reflux barrier.
The LINX™ device consists of a series of miniature magnetic beads linked together to form a “bracelet” around the lower oesophagus, supporting the LES. The magnetic attraction between the beads helps to keep the lower esophageal sphincter (LES) closed to prevent reflux, but will open to allow swallowing or the release of higher gastric pressures (eg during belching).

How is the device implanted?
The procedure is performed using keyhole (laparoscopic) surgery and takes around 30 minutes. The device is placed around the lower part of the oesophagus. Note that although movement of acid upwards is prevented, movement of food downwards is essentially normal. Once the device is placed it will begin working immediately.
Following the procedure, which will normally be carried out as a day-case (outpatient) procedure, patients should be able to resume normal diet and will typically resume normal activities in less than a week.
