Gastroesophageal Disease

Gastro-oesophageal reflux disease (GORD) is a common condition where stomach acid leaks back up into the oesophagus, which runs from your throat to your stomach. It is usually caused by a weakening of the ring of muscle at the bottom of the oesophagus. About a quarter of the population will experience an episode every year. GORD is often a chronic condition, which means that you may experience recurring symptoms. In some cases, acid reflux causes damage to the lining of the oesopaghus and needs careful treatment to avoid the development of complications such as ulcer, stricture or even cancer formation.

How common is gastroesophageal disease?

GORD is the most common diagnosis made by doctors in gastroenterology clinics and is thought to affect at least 10% of adults in western countries. The most common symptom of GORD is heartburn with 12% of Western populations experiencing heartburn once a week with 5% experiencing heartburn once a day.

Some GORD patients never experience heartburn but may have less common symptoms such as pain when swallowing, nausea and excess saliva. For many sufferers the symptoms of GORD can impact significantly on the ability to perform daily activities and can impact on quality of life.

What are the symptoms of gastroesophageal disease?

The main symptom of gastroesophageal disease is heartburn but you can also feel pain in the upper abdomen or chest. Patients can feel sick and experience acid reflux where stomach acid comes back into your mouth causing an unpleasant, sour taste.

Other symptoms are belching, a burning pain when swallowing hot drinks and bad breath. Symptoms usually occur after a large meal, or at night and may feel worse when you are lying flat.

How is gastroesophageal disease diagnosed?

An endoscopy examination using a thin, flexible telescope passed down the oesophagus into the stomach will give the specialist an accurate indication of the health of your oesophagus.

If reflux oesophagitis is suspected during endoscopy, then several small biopsies are taken from the lining of the oesophagus to determine the severity of the condition.

On rare occasions, specialised acid measurement tests are needed to confirm the diagnosis. Doctors can also ask for a barium swallow or barium meal that uses a solution and x-rays to chart blockages or abnormalities in the oesophagus.

Treatment of gastroesophageal disease

Lifestyle factors such as weight loss, dietary manipulations and smoking cessation are the first line of treatment. You can vary the amount you eat at meal times, maintain a healthy weight and avoid items that commonly trigger GORD such as coffee, chocolate, tomatoes, alcohol, fatty or spicy food. Drugs may be used to suppress the production of acid in the stomach and therefore reduce the amount of acid available to reflux into the oesophagus. These are well tolerated and effective.


In severe cases of GORD that cannot be treated by medication, individuals may be reffered to a surgeon who may reccomend a complex surgical procedure called fundoplication. Fundoplication involves wrapping the upper part of the stomach (fundus) around the lower end of the oesophagus and stitching it in place to artificially reinforce a weak lower oesophegal sphincter. When performed by expert GI surgeons in specialised centres, fundoplication is generally acknowledged as an effective and durable therapy for advanced GORD or patients with a large hiatus hernia. Often there can be unwanted side effects such as the inability to belch or vomit, which can cause some patients to be reluctant to proceed with this surgery.

The Linx System

The Linx System is suitable for chronic GORD sufferers who do not respond fully to medication. The LINX System is a simple procedure designed to provide a permanent solution to GORD by stopping reflux at its source. The operation does not alter the anatomy of the stomach and may be reversible if necessary.

What is the Linx Reflux Management System?

The LINX System is a medical device which is placed around the Lower Oesophageal Sphincter (LOS) using a simple technique called laparoscopy (keyhole surgery). The device consists of a small flexible band of interlinked titanium beads with magnetic cores and is placed around the LOS in the closed position. The beads will separate temporarily as the force a swallow allows good and drink to pass into the stomach. The magnetic attraction between the beads then brings the device back to the closed position to prevent reflux occurring. The magnets are calibrated to allow higher gastric pressures to open the device, but will not open for the lower gastric pressure of reflux. This means that the device will also open if there is a need to release increased pressure in the stomach (when belching or vomiting).

Who is the Linx System suitable for?

The Linx System is not suitable for every patient with reflux. It is suitable for people who have suffered from GORD for a number of years, who respond partially to medication. In addition, the individual should be able to swallow normally and have a healthy oesophagus. Patients are assessed for their eligibility following a series of tests. Two of the key tests are pH Monitoring and Manometry.

How effective is the Linx System?

A clinical study looked at the extent to which the LINX System had helped patients five years after it had been implanted. The results showed that the GORD symptoms had improved significantly, and that 85% of patients were able to stop daily PPI medication. Reassuringly, these patients also said their quality of life had improved.
