What is Gastro-oesophageal reflux disease (GORD)?
Gastro-oesophageal reflux disease (GORD) occurs when the acidic contents of the stomach flow backwards into the oesophagus causing inflammation of the lower oesophagus (oesophagitis). This may lead to a number of symptoms including heartburn, regurgitation of semi-digested food, difficulty swallowing and pain on swallowing. In addition, you may also experience welling up of a foul tasting fluid into the back of your mouth; you might also notice fluid welling up when you bend over to tie your shoes or to lift something up.
To learn about the causes and symptoms of GORD, visit our conditions page on Gastro-esophageal reflux disease (GORD or GERD) and Heartburn.
What are the options for treating GORD?
The majority of patients who have gastro-oesophageal reflux treat their condition with simple over the counter medicines, for example Rennies, and other medications that can be brought from the chemist that reduce the acidity in the stomach.
If these simple measures do not work then patients are commonly prescribed tablets that reduce the acid levels in the stomach. These drugs are collectively known as Proton Pump Inhibitors (PPIs, for example: Lansoprazole, Omeprazole, Esomeprazole, Pantoprazole and Rabeprazole). These drugs are highly effective at relieving the symptoms of gastro-oesophageal reflux; they do not do anything to the sphincter at the lower end of the oesophagus.
Sometimes patients notice an improvement in their symptoms if they lose weight or by giving up alcohol and smoking. We therefore generally advise people, who have severe reflux disease, to follow these measures and also to avoid eating large meals late at night and drinking large amounts of caffeine containing drinks and losing weight.
What is the aim of surgery?
Surgical operations for reflux disease aim to prevent acid reflux by reinforcing the valve mechanism at the lower end of the oesophagus so that the fluid cannot reflux into the oesophagus from the stomach. The sphincter mechanism itself cannot be directly repaired. Instead it is reinforced by buttressing the valve mechanism with the upper stomach.
Surgical treatment for acid reflux disease has been around for many years but has become more popular in recent times as key hole methods (laparoscopic) for carrying out the surgery have been developed and it is also related to the increased number of patients who suffer with GORD.
Who is suitable for surgery?
Surgery can potentially benefit the majority of patients who have troublesome acid reflux disease. However, it is important that you are fully aware of the different options for treating your reflux disease before going through an operation.
It is critical that a precise diagnosis of gastro-oesophageal reflux disease is made prior to surgery. It is most important to be certain that reflux is causing your symptoms. There are many other conditions of the oesophagus and stomach that can cause symptoms which may be interpreted as reflux. These other conditions are not helped by surgery and may be made worse. Therefore, your surgeon will help you carefully decide whether surgery is likely to help your symptoms.
The majority of patients who wish to explore the possibility of surgical treatment are those who have severe reflux symptoms that are inadequately relieved by taking medication. Some patients have the desire not to stay on long-term medication, or have had side effects from the PPI medications they have been prescribed.
What tests do I need before the operation?
Before you have a surgical treatment for your gastro-oesophageal reflux, it is important that we confirm that this is the problem that you have as other conditions can mimic GORD and they would not be helped by this type of surgery. You will undergo an endoscopy test to have a look to see if you have oesophagitis, (inflammation of your gullet), or a hiatus hernia.
You will also be asked to undergo some tests of your oesophagus to make sure that the muscles within the oesophagus work properly and strongly when you swallow. You will also be asked to undergo a test where a fine catheter tube is placed down your nose for a 24 hour period; this catheter tube measures the acid (pH level) in your lower oesophagus and allows us to confirm that you have an abnormal degree of acid reflux.
We will also ask you about your response to acid reducing medications as frequently patients who respond well to these medications do well after surgery.
Who makes the final decision regarding surgery?
When we have all the information available from your pre-operative tests we will discuss with you the pros and cons of surgery. If we feel you will benefit from the surgery then it will be your decision as to whether you wish to go ahead with surgery.
Before your procedure
- You will be asked to attend a pre-admission clinic where you will be seen by a member of the anaesthetic team.
- You will be asked details of your medical history and undergo a physical examination. We will arrange for any further investigations you may require to prepare you for your operation. We encourage you at this time to ask any questions about the procedure or any other concerns you might have.
- You will be asked if you are taking any tablets or other types of medication; these might be ones prescribed by your doctor or bought over the counter in a pharmacy. It helps us if you bring details with you of anything that you are taking: (i.e. bring the packaging with you or a full list of your medications).
- You will be asked if you are allergic to anything and details of operations you have had in the past.
- A member of the surgical team will discuss any issues you have and you will be given a consent form to take away with you at this time and to bring back to hospital when you are admitted.
- At the time of your pre-admission you will receive information regarding the details of your admission.
- Usually you will be admitted to hospital on the morning of your operation.
- You will be advised about what you can eat and drink before the operation and from what time you will need to be starved.
What happens when I am admitted?
- When you are admitted, you will be seen by the anaesthetist. They will review your medical history and information from the preclerking clinic and investigations. They will also want to know details of any previous anaesthetics you have had. The anaesthetist may examine you and will want to look in your mouth.
- You will also meet the surgical team who will be looking after you. If you have not already signed your consent form, you will be asked to do so.
- Before you go for your operation, you will be asked to change into a gown.
What happens during the procedure itself?
Before your operation you will be taken to the operating theatre and the anaesthetist will insert a plastic tube (drip) in your hand or arm through which you will be given an injection which will make you sleepy.
- During the operation the anaesthetist will stay with you at all times and you are closely monitored. Monitoring machines will measure your heart rate, blood pressure and oxygen levels within your blood.
- While you are asleep a fine tube will be passed through your nose into your stomach to drain the air off the stomach; this will be removed at the end of the procedure.
- We perform this type of surgery using a keyhole (laparoscopic) approach. This allows us to use long thin instruments and cameras to work inside your abdomen, using small incisions rather than through a traditional large incision.
- This approach means that you experience much less pain after the operation and thus, able to recover more quickly.
- There is always a small chance (2-5%) that a larger incision will be made on the abdomen. This is done if the operation is unable to be completed using the key hole technique or if there is a complication such as bleeding that cannot be controlled using a key hole technique.
- When the special keyhole (laparoscopic) instruments have been inserted the liver is lifted out of the way with a special instrument allowing us to identify the lower oesophagus and stomach, where we will do the actual operation. This area is freed up preserving the nerves that lie around this area that control your intestine. The upper part of the stomach (fundus) is then freed from its attachments. This involves dividing some small blood vessels that run between the fundus and the spleen.
- Once the fundus of the stomach and the oesophagus are completely mobile, the stomach is manipulated around the back of the oesophagus and stitched over the front of the oesophagus and back to the stomach (this is called a fundoplication). If you have had a hiatus hernia the diaphragm through which the hernia was extending will also be repaired using some stitches.
- The incisions will be closed with small metal clips and injected with local anaesthetic so that you are comfortable when you wake up.
- Your wounds will be closed with waterproof dressings, which means that you can shower. We ask you to remove the dressings yourself at home five days after the operation.
Who will perform my procedure?
- Your operation will be performed by a consultant surgeon or by a senior surgeon in training under the direct supervision of the consultant surgeon.
What happens following the procedure itself?
You will wake up in the recovery room after your operation. You might have an oxygen mask on your face to help you breathe. You might also wake up feeling sleepy.
After the operation, you will have a small, plastic tube in one of the veins of your arm. This will be attached to a bag of fluid (called a drip), which provides your body with fluid until you are well enough to eat and drink by yourself.
While you are in the recovery room, a nurse will check your pulse and blood pressure regularly. When you are well enough to be moved, you will be taken to a ward.
It is very important that you are not sick and you will be given a number of anti-sickness medications while you are asleep. If, after the operation, you feel at all sick, you must immediately inform the nurses looking after you.
After your operation, on the day, you will be allowed to drink water and then progress onto other fluids during the day as you feel able and are not feeling sick. You will be monitored carefully and given regular painkillers and anti-sickness medications to prevent sickness occurring.
The day after your operation, you will be seen by the surgical team and provided you are well you will be allowed to start eating soups and simple soft food. We advise you during this period to avoid liquids that are either particularly hot or cold, but generally take tepid fluids. We would also caution against taking fizzy drinks.
We would expect you to be discharged home one to two days after your operation.
Eating and drinking
We advise you to stay on a liquid diet for the first 3-4 days after the surgery and then to eat food that is soft, sloppy and easy to swallow for the first 2 weeks after surgery. This means avoiding foods that contain large pieces (for example, bread or red meat). Also you should avoid fizzy or carbonated drinks and when you eat solids, please make sure that you chew your food carefully and do not eat too quickly. Always take your time eating and chew your food very well.
If you are having difficulties swallowing initially, we advise you to only take foods of a consistency that are able to sucked up a straw. After about two weeks you should be able to increase this to sloppy foods such as mashed or vitamised foods for another two weeks.
When you can resume normal activities including work?
After your operation we would expect you to make a quick recovery from your surgery. You are able to resume normal activities as you feel comfortable. In general, you can resume driving a week or so after your operation. We would advise against extreme physical activity (weight lifting or heavy lifting), for about a month after the operation so that all the swelling and post-operative effects have settled down.
What are the possible occurring risks?
Keyhole (laparoscopic) surgery for acid reflux disease is a safe procedure. However, there are potential risks involved in any form of surgery and we believe that it is important that you are aware of these.
Damage to the spleen.
During the part of the operation discussed earlier, the small blood vessels between the spleen and the upper part of the stomach (fundus) are cut using special instruments that seal the blood vessels before they are divided. However, sometimes damage to the spleen can occur. Frequently this can be controlled simply using the keyhole method, however, if the spleen were to sustain more severe injury this may require conversion to an open cut operation with the potential of removal of the spleen.
Damage to the oesophagus.
When the oesophagus is being freed up inside your abdomen there is a risk that it can be damaged. If this is seen at the time of the operation it can be repaired simply and the operation will be completed using the keyhole method, or it may mean you need to stay in hospital for a slightly longer period of time to ensure that it heals up well.
Severe swallowing difficulty.
While we expect you to notice that things go down more slowly after your operation, a few patients experience severe problems with swallowing in the first few days after their operation. If this occurs, it may be necessary to perform a second keyhole operation to loosen or remove some of the stitches we have put in. Rarely, some patients find it difficult to burp – this is called gas bloat syndrome.
These are rare with keyhole surgery and if they do occur can be treated simply with antibiotics.
Damage to other organs inside your abdomen.
This is a rare complication of keyhole surgery but it has been recognised that during the insertion of instruments into the abdominal cavity damage can occur to any other intra-abdominal organs, including the intestine, liver and blood vessels. If this were to occur then it is likely that the approach to the operation would have to be changed from a keyhole approach to an open approach.
Because you are relatively comfortable and able to easily mobilise after the operation, chest infections are rare. If a chest infection did occur it could be treated with antibiotics.
Deep vein thrombosis (DVT) and pulmonary embolus.
All surgery carries varying degrees of risks of thrombosis (clots) in the deep veins of your leg. In the worst case, a clot in the leg can break off and travel to the lung (pulmonary embolism). This can significantly impair your breathing. To prevent these problems around the time of your operation and following your operation we give you some special injections to ‘thin’ the blood. We also ask you to wear compression stockings on your legs before and after surgery and also use a special device to massage the calves during the surgery. Moving about as much as you can, including pumping your calf muscles in bed or sitting out of bed as soon as possible reduce the risk of these complications.
Conversion to an open operation.
We always warn people who are undergoing a keyhole procedure that there is a small risk that if the operation is technically not possible to complete through a keyhole technique we will make an open cut. If this is necessary, it will result in a larger scar and more post-operative discomfort and, inevitably, a longer stay in hospital.
Any surgical procedure that involves making a skin incision carries a risk of scar formation. A scar is the body’s way of healing and sealing the cut. It is highly variable between different people. All surgical incisions are closed with the utmost care, usually involving several layers of sutures. The sutures are almost always dissolvable and do not have to be removed. The larger an incision the more prominent it will be. Despite our best intentions, there is no guarantee that any incision (even those only 1-2 cm in length) will not cause a scar that is somewhat unsightly or prominent. Scars are usually most prominent in the first few months following surgery, however, tend to fade in colour and become less noticeable after a year or so.
Requirement for re-operation.
It is unlikely (5%), although possible, that some time after the operation you may need a further procedure related to the fundoplication. This is because it possible for things to move slightly inside or for sutures to give way. If this is the case this may need to be corrected with another operation to revise the fundoplication. In very rare cases coughing, heaving or vomiting in the first few days after the operation can cause things to move or a suture to give way. This then may require another operation to correct things.
We have tried to describe the most common and serious complications that may occur following this surgery. It is not possible to detail every possible complication that may occur following any operation. If another complication that you have not been warned about occurs, we will treat it as required and inform you as best we can at the time. If there is anything that is unclear or risks that you are particularly concerned about, please ask.
You will be given a copy of your discharge summary.
What are the risks of general anaesthesia?
In modern anaesthesia, serious problems are uncommon. Risks cannot be removed completely, but modern equipment, training and drugs have made it a much safer procedure in recent years. The risk to you as an individual will depend on; whether you have any other illness, personal factors (such as smoking or being overweight) or surgery which is complicated, long or done in an emergency. Please discuss any pre-existing medical condition with your anaesthetist.

After the procedure
- The operation aims to increase the pressure of the valve mechanism at the lower end of your oesophagus
- You will, therefore, notice that in the first few weeks after your operation it is more difficult to swallow food than it was before your operation. This is entirely normal and advice is given later on in this information sheet as to the type of food you should be eating during this period.
- You need to be very careful about eating foods of a coarser texture, such as bread or red meat. If these are eaten too quickly or too large a mouthful is swallowed they may become stuck in the lower end of the oesophagus.
- Because the valve has been tightened it is difficult for patients to belch and this can lead to painful trapped wind. In a similar manner, it is also difficult for patients to be sick. All these symptoms do improve with time, but it is important that you avoid precipitating these symptoms as much as possible in the early post-operative period.
- Approximately 50% of the patients who have this operation notice that they pass more wind through their bottom after the operation. Simple medications that absorb gas can be obtained over the counter at a chemist.
