LINX Eliminated Daily Dependance on Acid-Reflux Medications in 79% of GERD Patients
CINCINNATI – Nov. 10, 2020 – Ethicon*, part of the Johnson & Johnson Medical Devices Companies**, announced today its LINX® Reflux Management System was shown to provide effective long-term control of gastroesophageal reflux disease (GERD) and eliminated the need for daily reflux medications in 79% of patients in the longest-term study ever published on magnetic sphincter augmentation (MSA).1 The study, which followed patients over a 6- to 12-year period, recently appeared in the journal Nature Scientific Reports.2
The LINX Reflux Management System is a flexible ring of small magnets placed around the lower part of the esophagus, the body’s natural barrier to reflux, during a minimally invasive procedure. The magnetic ring expands when a person ingests food and then contracts to prevent stomach contents, including gastric acid, from backing up into the esophagus and causing GERD, a condition that affects about 20% of people in the United States.3
In the single-center (IRCCS Policlinico San Donato in Italy) retrospective study of 335 patients who had an MSA procedure with LINX between 2007 and 2020, 124 patients who had been implanted for at least 6 years and up to 12 (median 9 years) were followed. Nearly 90% of LINX patients experienced long-term favorable outcomes defined as a greater than 50% improvement in their GERD-health related quality of life (GERD-HRQL) score and the discontinued use of proton pump inhibitors (PPIs), the current standard of care in medical therapy.4 There were no device erosions or migrations and only three instances (2.4%) of device removal due to either continued reflux symptoms, dysphagia or the need for an MRI in this long-term group.2 Patient satisfaction was 93.8% after 10 years.2
“Our new study corroborates the findings of previous studies but over a longer period of time, which is important for an implanted device,” said study co-author Luigi Bonavina***, MD, Professor of Surgery at University of Milan School of Medicine and Chief of the Department of Surgery at IRCCS Policlinico San Donato. “The efficacy of the LINX System remained strong and the risk of complications did not increase many years after implantation. Based on these results and the high levels of patient satisfaction, MSA may represent a true paradigm shift that has the potential to fill the current therapy gap in GERD.”
This latest study builds on more than 50 peer-reviewed articles,5 including a randomized clinical trial, that show procedures with the LINX System are more effective than twice-daily PPIs in normalizing reflux6 and more effective in reducing disease-related payer cost 12 months post-surgery than laparoscopic Nissen fundoplication, a more invasive anti-reflux surgery.7
Several GI and surgical societies, including the American Society of General Surgeons (ASGS), Society of American Gastrointestinal and Endoscopic Surgeons (SAGES), the American College of Gastroenterology (ACG) and the American Foregut Society (AFS), have issued consensus statements in favor of LINX procedures for appropriate GERD patients.
“Despite extensive clinical evidence, including this long-term study, and support from leading societies and academic centers, treatment with the LINX System remains out of reach for many patients due to inconsistent insurance coverage throughout the U.S.,” said Tom O’Brien, Worldwide Endomechanical President, Ethicon. “We are committed to providing the clinical and economic evidence that insurance carriers demand so patients with severe GERD can finally have access to the long-term relief they need and the potential for an improved quality of life wherever they happen to live.”

LINX® Reflux Management System Important Safety Information
The LINX® Reflux Management System is a laparoscopic, fundic-sparing anti-reflux procedure indicated for patients diagnosed with Gastroesophageal Reflux Disease (GERD) as defined by abnormal pH testing, and who are seeking an alternative to continuous acid suppression therapy (i.e. proton pump inhibitors or equivalent) in the management of their GERD.
Contraindications: Do not implant the LINX Reflux Management System in patients with suspected or known allergies to titanium, stainless steel, nickel, or ferrous materials.
Warnings: The LINX device is considered MR Conditional in a magnetic resonance imaging (MRI) system up to either 0.7 Tesla (0.7T) or 1.5 Tesla (1.5T), depending on the LINX model implanted. Scanning under different conditions may result in serious injury to you and/or interfere with the magnetic strength and the function of the device. In the event alternative diagnostic procedures cannot be used and MRI is required, the LINX device can be safely removed utilizing a laparoscopic technique that does not compromise the option for traditional anti-reflux procedures. It is recommended that patients receiving the LINX device register their implant with the MedicAlert Foundation (www.medicalert.org) or equivalent organization.
Failure to secure the LINX device properly may result in its subsequent displacement and necessitate a second operation.
Laparoscopic placement of the LINX device is major surgery and death can occur.
General Precautions: The LINX device is a long-term implant. Explant (removal) and replacement surgery may be indicated at any time. Management of adverse reactions may include explantation and/or replacement.
The use of the LINX device in patients with a hiatal hernia larger than 3 cm should include hiatal hernia repair to reduce the hernia to less than 3 cm. The LINX device has not been evaluated in patients with an unrepaired hiatal hernia greater than 3 cm.
The safety and effectiveness of the LINX device has not been evaluated in patients with Barrett's esophagus or Grade C or D (LA classification) esophagitis.
The safety and effectiveness of the LINX device has not been evaluated in patients with electrical implants such as pacemakers and defibrillators, or other metallic, abdominal implants.
The safety and effectiveness of the LINX Reflux Management System has not been established for the following conditions:
- Suspected or confirmed esophageal or gastric cancer
- Prior esophageal or gastric surgery or endoscopic intervention
- Distal esophageal motility less than 35 mmHg peristaltic amplitude on wet swallows or <70% (propulsive) peristaltic sequences or High Resolution Manometry equivalent, and/or a known motility disorder such as Achalasia, Nutcracker Esophagus, and Diffuse Esophageal Spasm or Hypertensive LES
- Symptoms of dysphagia more than once per week within the last 3 months
- Esophageal stricture or gross esophageal anatomic abnormalities (Schatzki’s ring, obstructive lesions, etc.)
- Esophageal or gastric varices
- Lactating, pregnant or plan to become pregnant
- Morbid obesity (BMI >35)
- Age < 21
Potential Side Effects: Potential adverse events associated with laparoscopic surgery and anesthesia include adverse reaction to anesthesia (headache, muscle pain, nausea), anaphylaxis (severe allergic reaction), cardiac arrest, death, diarrhea, fever, hypotension (low blood pressure), hypoxemia (low oxygen levels in the blood), infection, myocardial infarction, perforation, pneumonia, pulmonary embolism (blood clot in the lung), respiratory distress, and thrombophlebitis (blood clot). Other risks reported after anti-reflux surgery procedures include bloating, nausea, dysphagia (difficulty swallowing), odynophagia (painful swallowing), retching, and vomiting.
Potential risks associated specifically with the LINX Reflux Management System include achalasia (lower part of esophagus does not relax), bleeding, cough, death, decreased appetite, device erosion, device explant/re-operation, device failure, device migration (device does not appear to be at implant site), diarrhea, dyspepsia (indigestion), dysphagia (difficulty swallowing), early satiety (feeling full after eating a small amount of food), esophageal spasms, esophageal stricture, flatulence, food impaction, globus sensation (sensation of a lump in the throat), hiccups, inability to belch or vomit, increased belching, infection, impaired gastric motility, injury to the esophagus, spleen, or stomach, nausea, odynophagia (painful swallowing), organ damage caused by device migration, pain, peritonitis (inflammation of the peritoneum), pneumothorax (collapsed lung), regurgitation, saliva/mucus build-up, stomach bloating, ulcer, vomiting, weight loss, and worsening of preoperative symptoms (including but not limited to dysphagia or heartburn).
