Due to changes in the lifestyle, dietary habits and physical activity level GERD affects more and more people in contemporary world. For example, more than 20 million people in the USA currently suffer from this disease. During last few decades GERD treatment options have evolved from symptomatic drug treatment to comprehensive target surgical interventions.

One of the most promising techniques, which has already helped millions of patients in defeating GERD, is LINX Reflux Management System implantation. LINX restores natural passage of food along the gastrointestinal tract and directly prevents acid reflux. This minimally invasive technique has shown effectiveness in controlling GERD symptoms and improving quality of patients` lives.

What does the diagnosis GERD mean?

Abbreviation GERD stands for gastroesophageal reflux disease; another name of the condition is acid reflux. “Reflux” means moving backwards or returning. So, as it is obvious from the medical term itself, GERD implies abnormal movement of food and liquid between esophagus and stomach. To be more precise, GERD is a pathologic returning of the stomach contents upwards – to the esophagus. In healthy people such situation is prevented by correct work of lower esophageal sphincter (LES). LES is a bundle of muscles at the lower end of the esophagus, where it enters the stomach. LES provides one-way movement of food and liquid, preventing stomach acid, duodenal bile, digestive enzymes, and undigested substances from returning to the esophagus.

For some reason, this sphincter becomes weak and doesn`t perform its natural function in people with GERD. When we look at the disease superficially, reflux may seem not to be a problem. Indeed, if this food has passed through the esophagus once, then why should it cause harm when passing twice? The problem is in the acidic environment of the stomach and additional presence of digestive enzymes. Food with acidic stomach juices and bile injures unprotected and sensitive inner lining of the esophagus.

In GERD direct damage and subsequent inflammation of the esophagus tissues is a constant process, as GERD is a chronic condition. Permanent damage leads to arising of various clinical symptoms. Sometimes it can be really hard to reveal the true cause of complaints, as GERD influence is not restricted to gastrointestinal manifestations.

The most widespread signs of the disease include the following:

  • Heartburn. This is a burning feeling in the upper abdomen or in the chest. Sometimes it can spread to neck or angle of the jaw, and even be mixed with heart attack pain.
  • Regurgitation. This is sensation of stomach contents in the esophagus or even feeling acid taste of it in the oral cavity. Both heartburn and regurgitation are the most typical causes of sleep disturbances in patients with GERD.
  • Persistent cough. Irritation of mucous membrane and permanent inflammation result in dry cough; in this case need to clear the throat is not relieved by antitussives. Also reflux may result in voice changes (hoarseness) or feeling of a “lump” in the throat.
  • Stomatological problems and bad breath. When moving higher to the oral cavity, acidic contents of the stomach may harm gums and tooth enamel. In addition, normal microscopic flora (useful bacteria) of the oral cavity die in the acidic environment and bad breath appears.

GERD, especially in case of severe reflux, may worsen course of concomitant diseases, namely, bronchial asthma, ear infections, and chronic sinusitis. It should be emphasized that GERD is also considered to be a main cause of pre-cancerous condition – Barrett`s esophagus.

GERD treatment options

First of all, you should understand that reflux is a disease, not a simple and transitory reaction to inappropriate food. Like all diseases, GERD requires individual treatment, adjusted to clinical situation and general state of the patient.

In general, GERD treatment pursues two main aims:

  1. Lowering amount of acid in the stomach and thus reducing damage of the esophagus in case reflux has happened, andDecreasing volume of reflux or, if possible, avoiding it at all.
  2. Sometimes lifestyle modifications and dietary changes are totally enough for alleviation of GERD symptoms.

Recommendations in this field usually include the following:

  • Decreasing size of portions per meal. Excessive amount of food creates high pressure in the stomach and weak LES fails to prevent reflux. Reducing amount of food, at least per main meals, gives your stomach good chance to digest it properly and timely pass to the intestine.
  • Having last meal no less than 2-3 hours before going to bed. Lying in the bed changes pressure in the stomach and increases chance of having reflux. It is better to wait until the food leaves the stomach or, at least, elevate the head of the bed. Sleeping in different positions may also be beneficial.
  • Avoiding products that stimulate acid production. Here we are talking about alcohol, fatty food, fried products, spicy food, coffee and black tea, citrus fruits and juices.
  • Losing weight in overweight people. Excessive body mass creates excessive pressure in the abdomen and thus causes reflux.
  • Smoking cessation. Tobacco products cause transient LES relaxations and, naturally, aggravate course of the disease.

In case these measures don`t improve state of the patient significantly, doctors proceed to the next stage – medicinal treatment. The most widespread among GERD patients group of drugs is antacids. These non-prescription drugs are often seen in the advertisements, promising easy and effective relief. Indeed, they neutralize acid in the stomach and stop heartburn. The problem is, antacids provide only temporary relief, as their action is reversible and they don`t solve the problem itself. Additional measure, which improves the situation, is foaming agents’ usage. They create a foaming barrier on the inner lining of the stomach, directly protecting it from acidic environment. Antacids and foaming agents seem to be reasonable solution for GERD patients, but we should take into consideration their side effects in long-term use: diarrhea, calcium level disturbances, and increasing of serum magnesium level.

More serious treatment option is medicamental inhibition of acid secretion. Two groups of drugs are administered for this purpose: H2 blockers (like famotidine and ranitidine) and proton pump inhibitors (like omeprazole and pantoprazole). Using drugs may seem to be the most simple solution, as it is easy, may be performed by a patient independently and doesn`t require any surgical intervention. Nevertheless, such kind of treatment addresses only symptoms, not the cause of the disease – weak LES. In addition, GERD requires lifelong treatment, so buying drugs creates significant financial burden.

The only radical treatment option, which corrects origin of the disease, is surgical intervention. It is administered in case of severe reflux, influencing quality of life, poor response to drugs and threatening general state on the background of the disease. First surgical intervention, performed for GERD treatment, was Nissen fundoplication. This is open or laparoscopic procedure pointed at reinforcing LES work by partial stomach reconstruction.

More up-to-date endoscopic procedures include:

  • Fixing of LES, e.g. using electrodes in order to promote scarring and narrowing of LES, and
  • LINX Reflux Management System implantation.

LINX implantation is the latest technique that doesn`t require stomach reconstruction or trauma and significantly improves natural function of LES, addressing the pathologic background of GERD.

What is LINX?

The LINX Reflux Management System implantation is a laparoscopic, fundic-sparing procedure, which is helpful in fighting against acid reflux and indicated for patients with drug-resistance, serious side effects of medicinal treatment, bad quality of life and desire to stop lifelong drugs intake. LINX itself is a quarter dollar-sized device. It is a small flexible band of interlinked titanium beads with permanent magnetic cores, which are connected with the help of independent titanium wires, so they finally form an annular shape. Creator of LINX, Torax Medical, Inc., used Magnetic Sphincter Augmentation technology platform for development of the device. This technology uses attraction forces between the beads to improve and augment existing LES barrier function.

It is quite natural, that pressure in the stomach increases after the meal due to the volume of food. LINX placement helps LES to resist high pressure in the stomach after food intake, so it stays closed and acid reflux is prevented. To ensure normal food and liquid passage, process of swallowing temporary breaks the magnetic bond of LINX titanium beads, which slide away from each other on the independent titanium wires. Thus lower part of the esophagus becomes wider allowing food and liquid to come into the stomach. Right after swallowing magnetic attraction is restored and LES is successfully closed in its natural way. Totally imitating function of LES, LINX allows vomiting, if necessary (in poisoning, for example).

Unlike other surgical interventions, LINX Reflux Management System implantation doesn`t alter stomach function or anatomical structure, as it is placed around the esophagus in the projection of LES. Due to the high quality of the material (titanium) and personal adjustment of the device to size of the patient`s esophagus LINX placement implies lifelong use of the device with sufficient control of acid reflux and absence of clinical symptoms. As the technique is innovative, we are not able to talk about remote results of the treatment, but 1 and 2-year follow-up show favorable results. In addition, titanium structure of LINX creates no restrictions regarding MRI (up to 0.75 and 1.5 Tesla depending on the model) and passing airport security (this implantable device will not affect detectors).

LINX completely restores barrier function of weak or altered LED muscles and provides stable long term control of acid reflux symptoms. As it was shown by preliminary results of CALIBER Study (Randomized Controlled Trial of LINX Versus Double-Dose Proton Pump Inhibitor Therapy for Reflux Disease) in May 2017, LINX is more effective than omeprazole (mentioned above widely used anti-reflux drug) at reducing symptoms and improving quality of life in patients with GERD. This additionally confirms the idea about importance of direct reflux control, as simple lowering acid level in the stomach is totally not enough.

Proceeding to the surgery: how will it happen?

Treating GERD with LINX Reflux Management System implantation is a relatively new technique, but it has been already approved in few countries worldwide (e.g. USA, England, Germany). Some insurance companies also cover this variant of treatment, so you should check this option with your insurance company first. For example, Health Care Service Corporation (HCSC), which takes the 4th place among the commercial health insurers in the USA, and its affiliates of Blue Cross Blue Shield has provided a medical coverage policy for the LINX implantation since April 2016. Other important step before implanting LINX Reflux Management System is assessment of cautions and contraindications.

Surgeon will take a close look at the following aspects:

  • Age under 21 years old. LINX is indicated only for people with fully completed development of the gastrointestinal system. Growing esophagus is not suitable for the LINX placement. That is why the procedure is not indicated for the treatment of children and young adults.
  • Allergy to titanium, nickel, stainless steel and ferrous materials. These conditions are rare, but should be excluded, as LINX may cause severe allergy in such patients. It should be noted that nickel is a part of sizing tool, which is used during the surgery, not a component of the device itself. Thus nickel intolerance is not a strict contraindication.
  • Esophageal or gastric cancer. Medical use of LINX in cancer patients hasn`t been investigated in sufficient number of clinical trials and can`t be recommended with confidence. Such patients may benefit more from other treatment options.

The device is implanted with the help of minimally invasive laparoscopic procedure. This is a decent alternative option for more traumatic and anatomically disruptive Nissen fundoplication – usual anti-reflux surgical intervention.

Main stages of the intervention are the following:

  • Providing laparoscopic approach under general anesthesia
  • Precision sizing tool placement. Precision sizing tool is a part of LINX kit that determines individual appropriate size of LINX itself. LINX is available in different sizes in order to correspond to esophagus size of each patient
  • LINX Reflux Management System implantation. LINX is placed around the esophagus, namely around LES. Ends of the device are aligned and carefully joined to ensure secure closure
  • If a hiatal hernia is revealed during the procedure, it should be repaired during the same intervention
  • The surgery comes to the end, skin incisions are closed with the help of sutures. LINX is created for long term use, but removal or replacement of the system may be provided at any time, if necessary

As LINX Reflux Management System implantation doesn`t imply anatomic alteration of the stomach, patients may go home the day after the intervention. There is no need to be on a special diet afterwards. In the course of time LINX becomes covered with mucosa of the esophagus external part, this is the final part of the healing process. One more useful option for people with LINX is registering their device with the Medical Alert Foundation (available for patients from the USA) – in case they need MRI with strength over 1.5 Tesla in the future, LINX will be removed in the proper time.

Why is LINX implantation worth choosing?

Most people try to postpone surgical treatment as long as possible. This is natural, especially for people who have never gone through invasive treatment. We should take into consideration all pros and cons of the intervention. Usual arguments of patients who hesitate about treatment with LINX Reflux Management System are listed below.

The first sounds like: “It is not that serious. I`m strong and I will tolerate it without treatment., which is underestimating severity of the condition. At first sight reflux may seem no more than an unpleasant feeling. Some people prefer suffering from pain to having surgery.

Nevertheless, LINX implantation allows to control symptoms of acid reflux and, which is more important, to prevent serious complications of GERD:

  • Esophageal bleedings. Acidic content damages blood vessels of the esophagus, causing intensive and life-threatening bleedings.
  • Esophageal ulcers. Permanent injury gives mucous membrane of the esophagus little chance to restore structure and function. Chronic ulcers arise, making course of the disease more severe.
  • Narrowing (stricture) of the esophagus on the background of chronic inflammation. Constant inflammatory process stimulates excessive formation of the connective tissue. This finally leads to esophagus narrowing and difficulties with swallowing.
  • Barrett`s esophagus. Changes of mucous membrane, specific for this condition, are considered to be pre-cancerous ones. Controlling reflux is an obligatory measure of cancer prevention in this case.

The second argument sounds like: “Why should it be the surgery? Taking pills is quite enough!”. This position also seems reasonable, unless we take a look at the following facts:

  • Pills don`t address the cause of reflux, they just mask symptoms. Problem will arise again and again
  • In some patients medicinal treatment doesn`t provide full relief. Symptoms may become milder, but persist
  • GERD requires lifelong treatment. Taking pills every day may become tiring and bring financial problems
  • GERD medications have certain side effects, including problems with defecation and disturbed calcium exchange

The third one sounds like: “I don`t want to have surgery. It will cause more problems than GERD does at the moment.” Beyond all doubt, each surgery has certain risks and limitations, especially implantation procedures.

In spite of that, peculiarities of LINX Reflux Management System implantation include:

  • Minimally invasive surgery
  • No need to stay at the hospital more than a day
  • No need for specific diet, additional medications, etc.
  • Minimal restrictions regarding MRI (strength under 1.5 Tesla is possible)
  • Complete restoration of LES physiological function, no need in rehabilitation

One more advantage, that should be noted – LINX starts working immediately after the implantation, so you will feel positive changes from day one after the surgery. LINX improves quality of life significantly, avoiding all previous restrictions in daily activity and sport.

Where can LINX implantation be performed?

LINX Reflux Management System implantation requires specific skills and should be performed by the surgeon:

  • With appropriate experience in laparoscopic anti-reflux procedures
  • Who has attended product-specific training

In addition, the hospital must be equipped in a proper way to meet the technical requirements of this surgical procedure. Actually, only limited number of centers in the USA, Great Britain, Germany, Austria, and Switzerland are certified for performing such interventions. If you are not a citizen of abovementioned countries, you still have a chance to apply for treatment as an international patient. The possible problem in this case consists in waiting in a long queue of international patients, as higher priority in treatment list is given to citizens and patients with insurance. Another tricky moment is the arrangement of preoperative examination and handling all organizational questions during the trip.

Most appropriate option of arranging treatment abroad is using help of company Booking Health.
