If you get in touch with us, we will ask a few basic questions regarding your asthma history and smoking status.

There is a high prevalence of anxiety, depression and neurocognitive dysfunction which impacts on the wellbeing of patients with severe asthma. These factors may be the result of poorly controlled asthma, the effects of asthma treatments, but also themselves impact on asthma severity. The relationship between these factors is not well understood.

Magnetic resonance imaging (MRI) of the brain demonstrates structural and functional differences between the brains of people with asthma and those without. Though not extensively studied, a small number group of trials have shown a 'normalisation' of brain activity after cognitive behavioural therapy in patients with asthma and depression. The effect of asthma treatments on brain structure and activity requires further investigation.

Mepolizumab is amongst a group of injectable treatments that have revolutionised the treatment of poorly controlled severe eosinophilic asthma. Randomised controlled trial and real-world data shows reduced exacerbations and oral corticosteroid use in patients taking mepolizumab. Trials also show improved asthma-specific quality of life, though there have not been studies that have assessed anxiety, depression, well-being and cognition in detail.

In this observational study we propose to examine the MRI structure and function of the brains of people with severe eosinophilic asthma before and six months after starting mepolizumab as part of routine clinical practice. We will collect detailed health and neurocognitive information to evaluate changes in psychological health and cognition with mepolizumab. We will compare these data, to results in patients with well-controlled asthma. We will assess whether changes seen on MRI brain imaging relate to the direct effect of the mepolizumab on the brain, or of the secondary effects of improved asthma control that is known to be achieved by mepolizumab.

Many people with chronic obstructive pulmonary disease (COPD) remain very breathless and limited. In some patients, with the appropriate pattern of emphysema, an operation called lung volume reduction surgery is effective at removing the worst affected area of lung. New techniques have been developed where emphysema can be treated using a fibre-optic camera called a bronchoscope. Trials have shown that using a bronchoscope to place endobronchial valves into the airways can be very effective in carefully selected patients and the technique is now being adopted in hospitals across the UK.

This study will collect data from people undergoing these procedures at hospitals across the UK to evaluate how well they work in practice and what factors at baseline influence response. Baseline, three month and 12 month follow up data will be collected. This will include lung function data, measures of exercise capacity, questionnaires about health status and CT scan results. Questions addressed will include:

• What lung function improvement is seen in clinical practice?
• What factors determine who is most likely to respond?
• How safe are the procedures and what is the rate of complications?
• What proportion of people undergoing bronchoscopic procedures require repeat procedures or surgery subsequently?
• Does long term survival differ between people undergoing the different treatments?

The study is supported by The British Lung Foundation and sponsored by Imperial College, London. By building collaboration, the establishment of the network will also produce a structure that will make evaluation of future bronchoscopic techniques easier bringing innovative treatments into play more quickly.

When people get chest infections, fluid can sometimes build up around the lung. This is called a parapneumonic pleural effusion. In about 1 in 10 cases, the fluid itself becomes infected, this is called pleural infection. Pleural infection is usually treated by removing the infected fluid and using antibiotics to mop up the left-over infection.

Patients with pleural infection often receive long courses of intravenous antibiotics because doctors are uncertain of how well antibiotics reach the infected pleural fluid and whether bacteria are becoming resistant to them.

The Pleural Antibiotic Concentrations informing Treatment (PACT) study is observational and aims to see how well antibiotics are reaching the infected fluid, and how quickly the bacteria are being killed. To answer this, we will collect samples of pleural fluid from participants who are being treated for pleural infection with pleural drainage. This fluid will be tested to measure how much antibiotic has managed to get into it. We can then tell if the antibiotics are reaching high enough concentrations to kill bacteria. We will also be testing this fluid to see if the bacteria are being killed by the antibiotic or not. In the future, this information may shorten the time patients are treated with intravenous antibiotics and therefore how long they need to stay in hospital.

Background and study aims

Pleural mesothelioma is a cancer that affects the lung lining, caused by asbestos. Despite recent treatment advances, the prognosis is often poor. Prompt diagnosis is vital. A biopsy can diagnose mesothelioma, guide treatment and support compensation claims. However, some people need multiple biopsies, increasing the risk of biopsy-related complications and prolonging the time to diagnosis. Doing additional tests on initial biopsies may increase the chance of diagnosing mesothelioma and avoid repeat biopsies. This would allow anti-cancer treatment to be started sooner and improve survival. The extra tests are not genetic but look for genetic changes in the cancer that allow it to grow and spread. The genetic markers in mesothelioma are called BAP1, p16 and MTAP. If they have disappeared on biopsy mesothelioma is diagnosed. Another study was previously conducted on people with suspected mesothelioma who required further biopsies as their first biopsy did not give a diagnosis  It took place in eight UK centres and recruited 59 patients. This study aims to perform these additional tests on their biopsy samples to see whether this would have made the diagnosis sooner and removed the need for further biopsies. It will investigate how many biopsies could have been avoided, how much time would have been saved, how this may have impacted survival and what cost-savings this would have offered the NHS.

Who can participate?

This study includes the 59 participants in the original TARGET study who were recruited between September 2015 and September 2018. No additional participants will be recruited. Should any participants of the original TARGET trial wish to opt-out, they can contact the main contact below.

What does the study involve?

Biopsy samples taken as part of the participants’ routine clinical care will be tested for the markers of genetic change in mesothelioma (BAP1, MTAP and p16). The ability to make a diagnosis using these tests will be compared with the original diagnostic pathway, which was before the use of these tests.

What are the possible benefits and risks of participating?

The benefits of enrolling are to future patients, whose diagnostic process could be improved, with no additional requirements of TARGET participants. As there are no additional interventions required of participants and this will not impact management, there are no risks identified.

IPF is a progressive scarring lung condition causing coughing and breathlessness. IPF patients often have reflux disease meaning stomach acid may be breathed into the lungs, potentially damaging them. Medicines which stop stomach acid production, proton pump inhibitors (PPIs), can be used to reduce reflux symptoms including heartburn. Some researchers suggest PPIs also reduce IPF progression.

This research aims to see if IPF progresses slower if treated with PPIs. Based on the results, we will be able to recommend whether or not IPF patients should take PPIs.

This trial will involve 298 IPF patients from approximately 37 UK hospitals. At the beginning of the study, we will ask patients to perform breathing tests, and ask those with a cough to use a device to count the number of times they cough in 24hours. We will ask them to answer two questions rating their coughing and breathlessness, and complete questionnaires on their coughing, IPF, sleep habits and general condition. People will be given a PPI, called lansoprazole, or dummy tablets, twice per day for 12 months. They will be given a leaflet telling them what to do about reflux symptoms. At the end of the study, we will repeat these tests and analyse the results. We will record any side effects people may get. If people suffer side effects, they can reduce the dose.

People taking medicines that interact with PPIs or have other serious medical conditions won’t be able to participate. People receiving PPIs will only be able to participate if they can stop taking their medication without their heartburn returning.

The study will be undertaken by doctors and researchers with experience of IPF, reflux disease, PPIs and coughing. We will publicise our results by writing reports for medical publications, media articles and social media.

(Diagnostic Yield study for Average MammOgraphic screeNing Density): A multicentre study offering women a FAST MRI scan in addition to their screening mammogram, to see if FAST MRI can find cancers missed by mammography

Aim:

To see if FAST MRI, a new imaging test, can detect cancers that have been missed by mammograms for women with average breast density at their first screening mammogram (age 50-52).

Background:

Finding breast cancers early saves lives. The NHS breast screening programme uses mammograms tofind breast cancers early but sometimes a mammogram misses a cancer which keeps growing until the woman finds it herself. MRI (Magnetic Resonance Imaging) detects aggressive cancers better than mammograms but is expensive and the NHS uses it to screen only women at very high risk. FAST MRI is a shorter MRI test which might benefit more women by finding more breast cancers earlier and saving more lives.

Every woman’s breasts are different. Breast composition affects how they look on mammograms. Women with denser breasts are more likely to have their cancers missed on mammograms because dense breast tissue can hide a cancer. Of four density categories (A,B,C and D), A is the least dense and D is the densest. At age 50-52, about 8 of 10 women will be in one of the middle categories, B or C, about half in each. We already know from previous research that FAST MRI can find cancers missed by mammograms in women with denser breasts (C and D). But women with average breast density (B) also have cancers missed, because mammograms are better at finding some types of cancer than others. We want to find out if FAST MRI can detect additional cancers for this group of women (category B). Women in category A are least likely to benefit as their mammograms show any cancers present more clearly and easily.

Design and methods used:

We will invite women aged 50-52, the age when women at average risk of breast cancer are first invited for an NHS screening mammogram. We will use computer software to measure women’s breast density from their mammogram and invite women with breast density in category B and a normal mammogram result to have a FAST MRI scan. 1,000 women will be scanned at 4 NHS sites, chosen for the ethnic diversity of the screened population and the experience the site has in working with FAST MRI. This choice of NHS sites will ensure our sample is representative of the UK. NHS professionals who have completed FAST MRI reader training will interpret the FAST MRI scans. We will count the total number of cancers detected by FAST MRI and record the types, aggressiveness and size of cancer found. We will count how many women need further tests but turn out not have cancer. We will ask women to share with us their experience of having a FAST MRI. The results will help us decide which women should be included in a future FAST MRI trial to measure if FAST MRI is clinically and cost effective for the NHS by finding breast cancers earlier and saving lives.

Patient and public involvement (PPI):

Patients and the public are integral in our work and we have ongoing support from:

1. Breast Cancer Unit Support Trust (BUST)
2. National Cancer Research Institute (NCRI) Breast Group
3. Independent Cancer Patients’ Voice (ICPV)

Our two lay research team members with personal experience of breast cancer and of breast screening will work with the wider PPI group to write public-facing documents so that participants and the public understand the research. They will also work to increase diversity, equality and inclusion in the PPI group.

Dissemination:

We will publish the results in academic journals and present at international meetings. Our PPI network will help us to share the results with charities and support groups locally and nationally.

(OPtimisation of the FAST MRI protocol: an Evaluation of what makes a good breast MRI through detailed Analysis of scans from multiple NHS sites)

Background:

Finding breast cancer early saves lives. The NHS Breast Screening Programme (NHSBSP) uses mammograms to detect early breast cancers. However, not all cancers show on a mammogram so a cancer can be missed and continue to grow until the woman finds it herself. Magnetic Resonance Imaging (MRI) scans are better at detecting cancers than mammograms. However, MRI is expensive, and the NHS only uses it to screen women classed as high risk of developing breast cancer.

Recent studies have shown that using only part of the full breast MRI scan detects cancer equally well as the full scan, but is a much quicker scan with lower costs. This technique is called FAST MRI and has the potential to save more women’s lives by finding breast cancers earlier than a mammogram and providing value for money for the NHS. A group of research studies led by North Bristol NHS Trust aim to develop a better breast screening programme using FAST MRI for women who currently have mammograms, to screen for breast cancer.

How easy it is to see a breast cancer on an MRI scan depends on the scan quality and the technical details of the scan, known as the protocol. Quality control is therefore crucial for breast screening to optimise the detection of cancers.

This pilot study will develop a standardised and optimised protocol to be used in a separate multicentre trial of FAST MRI for women having their first screening mammogram (DYAMOND).

Aims:

1. Define the parameters that make a good quality FAST MRI scan.
2. Standardise the scan protocol across NHS sites to enable quality control during FAST MRI research trials and future clinical practice.

Design and Methods:

Our study will analyse breast MRI scans from different scanners across NHS sites within the FAST MRI Research Programme. Anonymised scans will be sent electronically to a panel of Breast Radiologists who will each score the scans for multiple aspects of scan quality. A team of Medical Physicists will also extract the numerically measurable aspects within each of the sites’ scan protocol and images. These two information sets, radiologists’ visual assessments and objectively measured values, will then be analysed to discover which settings make the optimal FAST MRI scan for each type of MRI scanner used. Site specific recommendations will be made to improve scan quality.

(EvaluatioN of an Artificial Intelligence (AI) Tool developed within and owned by the NHS to accurately measure mammographic breast Density): Selection for personalised screening with FAST MRI.

Background:

Finding breast cancer early saves lives. The NHS uses mammograms to try and detect early breast cancers. However, as mammograms do not show some cancers very well, a cancer can be missed and continue to grow until the woman finds it for herself. MRI (Magnetic Resonance Imaging) is a test that can find cancers better than mammograms, but it is expensive and so the NHS only uses it to screen women at very high risk of breast cancer. A quicker, shorter MRI test is now available called FAST MRI. Not only might this test benefit more women, it may also provide better value for money for the NHS to find breast cancers early and save lives. 

Every woman’s breasts are different. One way they differ is in a characteristic known as mammographic or breast density, which affects how they look on mammograms. Women with denser breasts can have their cancers missed on mammograms, as the dense normal tissue can hide the cancer. FAST MRI is better at finding these cancers.

To find out which women have dense breasts and could benefit from a FAST MRI, the mammograms need to be studied and measured. Currently, breast density is looked at and estimated by the radiologist but as each radiologist might view images slightly differently, results for breast density might not always be correct. There are now better systems to do this using (expensive) technology.

Aims:

To evaluate the accuracy and reliability of a breast density measurement tool. This will provide the National Breast Screening Programme (NHSBSP) with the ability to describe a woman’s breast density. If this tool is successful, it will further enable the North Bristol NHS Trust led FAST MRI research programme to develop a better breast screening programme.

Methods:

Our study uses an NHS developed and owned artificial intelligence (AI) software tool to automatically categorise the breast density. The cost to other NHS organisations will therefore be much lower when compared to commercial software. In this study we have tested our tool on anonymised mammograms, held in a research database called OPTIMAM, and compared the results to measurements made by commercial technology.

Our study looked at women aged 50-55, the age when women at average risk of breast cancer in the population are first invited to attend for an NHS screening mammogram.

A study to improve FAST MRI interpretation training and to enhance Breast Clinician and Advanced Practitioner Radiographer understanding of breast MRI at multidisciplinary team (MDT) discussions.

Background:

FAST MRI (a shortened form of breast MRI) has been developed to address limitations of full protocol breast MRI (fpMRI), by shortening the time needed to acquire and to report the scan. FAST MRI diagnostic accuracy is similar to fpMRI and therefore has potential for wider use in screening but to roll it out on a larger scale more readers skilled at interpreting FAST MRI would be needed. Initial evaluation showed NHSBSP mammogram readers could be trained to interpret FAST MRI with a single day of structured training, but novice MRI readers were still learning at the end of the final assessment task and therefore it is likely that further training could further improve their performance. The current study aims to see if further training can enable novice MRI readers to match the performance of experienced breast MRI readers at FAST MRI interpretation. The improvement in novice reader performance during the training will be monitored to enable evaluation of their "learning curve” so that we can find out how much training mammogram readers need to enable them to interpret FAST MRI scans in clinical practice.

Methods:

Mammogram readers from seven NHS sites in England will undertake the developed North Bristol FAST MRI interpretation training programme. The final assessment task of the training programme has been updated for this study (since its use in the previous Multi Centre Reader Training Study) so that feedback (the true results of each FAST MRI scan) is given to the readers immediately after they have recorded their opinion about the scan. This modification to the assessment task is known as "formative assessment” in educational theory and has been shown in education research to be an effective teaching tool. Because the FAST MRI scans of the final assessment task are presented to each reader in a different random order, we will be able to map the learning curve of each reader as they complete the final (formative) assessment task.

Background:

To be able to get high quality FAST MRI images it is important that the correct protocol (information/sequences programmed into the scanner) is optimised. To do this test (phantom) breast need to be developed to trial the protocols to put into the MRI machine.  

Aims:

To develop breast test objects to ensure an optimum FAST MRI protocol (the information put into the MRI scanner to run the scan) and develop a quality assurance (QA) programme that can be used across different sites and MR scanner vendors.

Methods:

This phantom development work includes the design and construction of 2 magnetic resonance imaging (MRI) test objects that will be used for quality assurance (QA) tests of MR scanners at centres participating in the FAST MRI project.

One of these test objects will be used to assess the dynamic range of the dynamic contrast enhanced (DCE) sequence and the other the resolution in 3 dimensions. The MRI test objects will be trialled at NBT initially in order to finalise the design.

Background:

After the promising results of the single centre study, the FAST MRI training programme was awarded an NIHR grant to expand and develop the FAST MRI training further.

Aims:

The aim of this study was to refine and pilot a training programme for FAST MRI interpretation within the NHS Breast Screening Programme (NHSBSP) workforce, to support the delivery of a future multicentre study of FAST MRI versus mammogram for breast cancer screening.

• Produce an electronic version of a standard teaching tool and data collection tool working in close partnership with NHS based SciCom team (Workstream 1).
• Pilot the standard teaching tool across six NHS sites within the South West region, UK and collect data on the accuracy and speed of FAST MRI interpretation following training (Workstream 2).

Methods:

The aim was achieved in two work streams:

• Workstream 1: Production of electronic versions of a standard teaching tool and of a data collection tool.
• Workstream 2: Pilot the standard teaching tool across six NHS sites (NHSBSP screening units) within the South West region of England (Truro, Plymouth, Taunton, Avon, Cheltenham and Swindon) and collect data on the accuracy and speed of FAST MRI interpretation following training. In addition, a Budget Impact Analysis to assess potential cost savings and affordability to the NHS to be assessed by the research team’s Health Economist as part of this workstream.
• Training: The teaching tool was used to train at least 12 readers from six centres to read FAST MRI. One day group training replaced the one-to-one training (used in the previous single centre study). This was made possible by the electronic teaching device.
• Follow-up interview: Study participants who gave consent to be contacted for future studies were invited to take part in a follow up interview to find out more information about how the readers felt about the study.

Conclusions:

• NHSBSP mammogram readers who completed the FAST MRI training programme achieved diagnostic performance at FAST MRI interpretation (in the final assessment task of the training programme) within international benchmarks (standards) published for full protocol breast MRI.
• The single day of training was not enough to enable mammogram readers who were new to breast MRI to interpret FAST MRI quite as well as mammogram readers who were experienced in full protocol breast MRI interpretation.
• Mammogram readers who were new to breast MRI interpretation continued to improve at how well they could detect breast cancers from FAST MRI scans during the final assessment task of the training programme. This showed that they were still learning during the final task and means that their diagnostic performance might improve further if given further training.

Background:

Mammographic screening programmes result in both over diagnosis and under diagnosis of breast cancer. Under diagnosis leads to cancers presenting symptomatically between screening visits (interval cancers), and to cancers being detected by screening only once they have already reached more complex and life-threatening stages.Although MRI is the most sensitive method to detect breast cancer, currently only women classified as high risk (>30% lifetime risk) are offered screening MRI in the UK. However, in the future, personalised screening could enable larger numbers of women to be offered different screening regimes, each incorporating different imaging modalities, according to their level of risk.

Finding breast cancer early saves lives, and there is therefore a need to develop cost-effective imaging tests that will benefit women at risk of breast cancer by finding significant disease early. First post-contrast Acquisition SubtracTed (FAST) MRI is a type of abbreviated (shortened) breast MRI. FAST MRI is essentially as accurate at breast cancer detection as full protocol breast MRI, but is much faster to acquire and report. This technique might benefit more women than are currently offered screening with full protocol breast MRI. FAST MRI may be especially useful for women with dense breasts, since cancers obscured by dense tissue on mammograms are often visible on MRI

Aims:

The aim of this study was to explore whether NHS breast screening programme (NHSBSP) mammogram readers can learn to effectively interpret FAST MRI with less than one day’s additional training and to match the capabilities of expert breast MRI readers at this task in terms of accuracy and speed of interpretation.

Methods:

FAST MRI images were created by using previously acquired full protocol breast MRI scans. The anonymised images were reformatted and simplified into a form equivalent in its display to a FAST MRI. Using these FAST MRI images, training was offered to colleagues at Bristol Breast Care Centre.

Four consultant radiologists who were qualified to report full protocol breast MRI and four screening mammogram film readers who had not previously been trained to report MRI were trained to read FAST MRI. They were shown a set of training images with answers in a one to one session with the Chief Investigator, and the length of time taken to train each person was recorded.

Results:

The findings showed that the brief structured training carried out in the study enabled multi-professional mammogram readers to achieve similar accuracy at FAST MRI interpretation to that of the consultant radiologists experienced at breast MRI interpretation.

During her training she did projects in phantom construction and functional MRI analysis, and a placement at the Cardiff University Brain Research Imaging Centre on diffusion MRI analysis.

The FAST MRI programme includes several Public and Patient Involvement representatives. They sit on the Trial Steering Committee giving input into the conduct of the study progress of the trial/project, adherence to the protocol, and the consideration of new information of relevance to the research question. They comment on the rights, safety and well-being of participants and proposals for substantial protocol amendments and provide advice to the sponsor and funder regarding approvals of such amendments.

Their membership is invaluable as they are able to ensure that patients are at the centre of the research conducted as part of the FAST MRI programme; reviewing documentation to make sure that it is written in lay language and that results from the studies are disseminated to the general public.

Public Representatives:

• Jenny Wookey is the Chair of BUST (North Bristol Trust’s Breast Cancer Unit Support Trust).
• Jan Rose is a member of the ICPV (Independent Cancer Patient’s Voice) and National Cancer Research Institute Breast Group.
• Helen Matthews works for the civil service in educational policy. She was diagnosed with high grade ductal carcinoma in situ (DCIS) in November 2021 following a routine screening mammogram, underwent treatment and is now continuing to lead a healthy and active life. She has joined the team to encourage the expansion and effectiveness of routine testing, knowing that it has saved her life.

In this test you drink a special high dose lactose and they test how much hydrogen gas is in your breath. If your body does not break the lactose down, the bacteria that live in your colon will ferment it. This makes a lot of hydrogen gas so a high level of hydrogen in your breath means you have lactose intolerance.

The test results are not perfect. Some people have a positive breath test but no symptoms. Some people have a negative test but still have symptoms. Sometimes a lactose free trial is better.

This is a good choice instead of the breath test.

Stop having lactose for a short time (around 2-4 weeks). If you do not feel better, then you do not have lactose intolerance and you can start having lactose again.

You can talk to your doctor or dietician about what else could help your symptoms.

Most people with lactose intolerance can have a food that says:

• May contain milk.
• Made in a factory that handles milk.
• Not suitable for people with a milk allergy. 

Casein and milk protein are sometimes listed within the ingredients and are proteins found in milk. You can have both these ingretients.

Some people have an allergy to milk protein but this is not the same as lactose intolerance.

You need vitamin B12 to help with energy release, healthy blood, and the nervous system.

Non-dairy sources of vitamin B12:

• Meat.
• Eggs.
• Fortified breakfast cereal.
• Yeast extract (marmite).
• Salmon.
• Cod.

You need calcium for bone health. Milk and dairy are the main sources of calcium.

• Lactose-free milk has the same amount of calcium as cow’s milk.
• If you use a milk alternative (oat/soya/coconut/nut milk), make sure it has added calcium.
• Organic milk alternatives do not have calcium added to them.
• Tinned fish with bones(sardines, pilchards, salmon)are very high in calcium.
• Oranges, almonds, Brazil nuts and tofu also contain calcium but it is not so easily absorbed.

You may need to take a calcium tablet if your bone health is high risk such as:

• Breastfeeding mothers
• Post-menopausal women
• Coeliac disease
• Inflammatory bowel disease

You need vitamin D to use calcium. The body makes vitamin D from sunlight on your skin. In the UK there is not enough sunshine in autumn or winter to make all the vitamin D that we need. Consider taking a vitamin D supplement daily in autumn and winter.

Vitamin D is in oily fish, red meat, offal, and egg yolks. Some breakfast cereals, margarines and non-dairy milk alternatives have vitamin D added.

You need protein for growth and repair, and to keep you strong. Some lactose free milks have more protein than others.

Lactose free cow’s milk and soya milk contain the most protein; oat and nut milks contain the least protein.

Eat 2 - 3 portions of high protein foods daily.

Non-dairy sources of protein include meat, fish, eggs, beans/ pulses, tofu, and nuts.

• Cereal with lactose free milk
• Toast with dairy free spread and jam

• Sandwich with dairy free spread and tuna/ham/chicken/ hard cheese, and salad.
• Homemade soup without milk or cream.
• Jacket potato with dairy-free spread, tuna/baked beans/ hard cheese, and salad.
• Eggs or baked beans on toast with dairy free spread.

• Meat/chicken/fish with potatoes or rice and vegetables.
• Omelette/frittata with side salad.
• Spaghetti Bolognese.
• Curry made without yoghurt, with rice and dahl.

• Fruit.
• Nuts.
• Crisps (not cheese and onion).
• Oatcakes/ rice cakes/ crackers with dairy-free spread.
• Tea, coffee, squash, lactose free milk.
• Dark chocolate.
• Biscuits.

Not always, but this will be discussed with your doctor or speech and language therapist.

The tube itself will not affect your ability to eat and drink. Some patients decide to still eat small amounts for pleasure. Some use the tube to provide extra nutrition on top of what they eat and drink.

If you decide not to have a feeding tube, it is unlikely that there are any other ways to meet your dietary needs. You should discuss your choices with your doctor and dietitian.

If you decide against tube feeding you will be supported in this decision. Please make sure you know the risks you may be taking.

All types of feeding tube are placed in hospital. 

If you are not already on a ward:

• A few days before the operation you may have a blood test and a swab taken by the GP.
• You may be asked to stop taking certain blood thinning medications for a few days before the operation. You may receive a phone call with more information before the operation.
• You will need to come in on the day of the operation.

If you are an inpatient:

• The ward team will advise you about stopping any blood thinning medications. They will also complete blood tests. 

Before the operation:

• You will be asked to have no nutrition (food) for at least six hours before the operation. You will also be asked to have no fluids for two hours before the operation. You may be given medication through a drip.
• The doctor will examine you, explain the operation and ask you to sign the consent form.

You will likely stay in hospital for at least a night for monitoring.

Most people will not have any serious issues from their tube placement. However, the risks of a complication increase with age. Your risk of having issues is also increased if you have from heart, chest, or other medical problems, such as diabetes, or are overweight, or smoke.

Major complications occur in around 3 in 100 people and include:

• Breathing problems.
• Heart complications.
• Peritonitis (swelling in stomach wall).
• Bleeding.
• Bowel perforation (accidental tear in your gut).
• Wound infection.
• Fistula formation (two organs connect).
• Leaking around the tube.
• Tube blockage.
• Buried bumper (stomach grows over part of the tube).
• Over granulation (excess skin grows on the tube).
• Infection.

There is a low mortality rate. To minimise complications, we will choose the technique that is safest for you. 

This is done in the Endoscopy Department. You will be given a local anaesthetic to your stomach, some throat spray, and light sedation (to make you feel relaxed). An endoscope (a flexible tube with a light and camera at one end) is passed down into your stomach and lit up.

A small cut is made in your stomach where the light shines and the tube is then passed through. The operation usually takes around 20 minutes.

You will be in the unit for some time before and after the operation.

This is what a PEG tube looks like: 

This is done in the Interventional Radiology Department. A narrow tube is passed through your nose into your stomach. Air will be passed into your stomach through the tube to make it visible on X-ray.

Local anaesthetic will numb your stomach. A small cut is made in your stomach and a wire is passed through to your mouth. The feeding tube is then passed through.

This operation typically takes 30 minutes.

This is what a PIGG tube looks like:

This is done in the Interventional Radiology Department. A narrow tube is passed through your nose into your stomach. Air will be passed into your stomach through the tube to make it visible on X-ray.

Local anaesthetic will numb your stomach and stitches are placed to hold the stomach close to the wall of the abdomen. A small cut is made near the stitches and a feeding tube is passed through into the stomach.

This operation typically takes 30 minutes.

This is what a RIG tube looks like:

• Once back on the ward it be 4-24 hours before you can use the tube. The nursing staff will tell you when you can start to use the tube.
• Water will be put through the tube first, followed by feed. Your dietitian will discuss the amounts and timings with you.
• The nutrition given through the tube is a prescribed liquid mix of the nutrition your body needs. We call this “specialist feed”. The specialist feed, water, and medications can be put down the tube using a special syringe or pump.
• You will need to sit upright during feeding and for 30-60 minutes afterwards.
• The dietitians will provide training on how to give the feeds and water flushes. This will be done as soon as possible so that you can go home quickly. Either the nursing staff on the ward or the community feeding team can provide further training.

After your tube has been inserted there is an increased risk of complications. If you are going home within 72 hours after the tube is inserted, you will need to be aware of these.

1-5 days after insertion 

Once the tube is safe to use, you will begin to receive feed, medications, and water through the tube.

Flush the tube with water before and after you give the feed or medications to prevent the tube blocking

You should flush the tube with a minimum of 30mls of water every day if you are not giving nutrition or medications through the tube.

Clean the tube site (area where tube enters the skin) every with sterile water. Do this once or twice a day for the first 5 days.

After 5 days, use mild soapy water. Dry the area around the tube gently but thoroughly. Do not reposition the fixation device (triangle) unless advised.

Check for signs of pain, redness, swelling or leakage. Report any concerns to medical staff or the community feeding team.

The tube site doesn’t need a dressing after the first1-2 days. A simple gauze dressing can be used if there is leakage around the tube site.

2 weeks after insertion 

Continue to clean the tube site including around the fixation device with mild soapy water and dry well.

2 weeks after insertion, or when the tube site has healed, it is important to prevent the overgrowth of skin around the tube inside the stomach. We call this ‘buried bumper’ syndrome.

To prevent a ‘buried bumper’, the tube needs to be moved daily. This is called “advancing and rotating” the tube. The dietitian will show you how to do this before you leave hospital. The community feeding team will also demonstrate this.

To “advance and rotate” the tube: 

1. Release the blue clip on the fixation device (triangle).
2. Move the fixation device at least 4cm away from the stomach.
3. With mild soapy water, clean both the tube site and the length of tube between the fixation device and stomach.
4. Push 3-4cm of tube into the stomach.
5. Turn the tube in a full circle (360 degrees).
6. Pull the tube back until you feel some resistance.
7. Wipe the tube clean.
8. Place the fixation device approximately 5mm (pound coin width) from skin and close the blue clip. See Fig 6 and Fig 7 below.

This should only be done when the tube site is healed. 

1-7 days after insertion 

You shouldn’t eat or have anything via the tube for at least 4 hours after insertion.

You shouldn’t eat or have anything through the tube for at least 4 hours after insertion.

After this the tube will be flushed with 50ml of sterile water. If there are no concerns after 2-3 hours, then the tube is safe to use.

If there are signs of pain or leakage, let the nurse know.

You may have a dressing over the tube. The dressing should be changed every day for the first 7-10 days after insertion.

Clean the site every day with sterile water. You can lift the edges of the bolster (white circular disk) and clean underneath. Make sure the area around the tube is dried well.

Do not move the bolster for first 2 weeks after insertion.

Always check the marking where the bolster sits before putting anything through the tube. If there is a change in position of the tube do not use and contact the community feeding team immediately.

7-10 days after insertion 

Some people like to keep a simple dressing on the tube but it is no longer needed.

Continue to clean the tube site with sterile water and dry well.

2 weeks after insertion  

The stitches can be removed if they have not dissolved after 2 weeks. This can be done by the nutrition nurses.

The tube can be rotated daily once stoma tract has healed to prevent any overgrowth of skin. To do this, clean around the site with warm mild soapy water and dry well. Make sure you lift the edges of the bolster and clean underneath. Turn the tube in a full circle (360 degrees).

The water in the balloon should be changed 2 weeks after insertion and once a week after that. This is to make sure the balloon stays inflated to hold the tube in place.

In hospital, the ward dietitian or nurse will change the balloon water. You will be shown how to do this by the dietitian or community feeding team. When changing the balloon water, you can “advance and rotate” the tube at the same time. This helps prevents any overgrowth of skin on or around the tube.

To “advance and rotate” the tube:

1. Make note of the mark on the tube where the bolster sits.
2. Gently move the bolster away from the skin surface by at least 4cm.
3. With mild soapy water, clean both the tube site and the length of tube between the bolster and stomach.
4. Push 3-4cm of tube into the stomach.
5. Turn the tube in a full circle (360 degrees).
6. Pull the tube back until you feel some resistance.
7. Wipe the tube clean.
8. Place the bolster back to the original position approximately 5mm (pound coin width) from skin.

The tube needs to be changed around 3 months after insertion. This is usually done where you live by the community feeding team.

Further tube changes will usually be done every 3-6 months. If you wish, you or your carers can be trained to change the tube yourselves.

Medicines can block the tube if they are not given correctly. You may need to be prescribed medicines in a more suitable form such as liquid. Your doctor or pharmacist should arrange this for you. Each medication should be given individually.

To help prevent tube blockage, we advise you do not give anything other than the feeds, water, and medications through your tube.

If you are unable to flush the tube or can see a blockage you should:

1. Ensure all clamps are open and the tube is not bent.
2. Massage the tube to try to dissolve any blockages.
3. Flush with 50ml warm or soda water, leave for 30mins and re-flush. Never use pineapple juice, cola or lemonade as they can make the blockage worse.
4. Try the ‘push/pull’ action with a syringe as advised by nursing staff.
5. Contact community feeding team or call the 24 hour helpline on your feeding regimen.

Note: For a RIG tube, only trial these methods if the tube can be advanced and rotated. Otherwise, contact your community feeding team. 

The tube can be removed if you no longer need it or want it removed. If well cared for can last several years.

The RIG tube will be changed every 3-6 months.

If the tube comes out you will need to go to your nearest accident and emergency department immediately. The longer the tube is out, the greater the risk of the site closing over.

If your RIG tube comes out, ring the community feeding team or 24 hour helpline. You may need to go to your nearest accident and emergency department to have another tube inserted.

The community enteral feeding nurses may have trained you to insert a device into the stoma called Corstop ACE stopper or ENPlugs.

In the case of the tube coming out, you can insert this device. Then call the community feeding team or 24 hour helpline for further advice.

Can I shower/bath? 

You can shower from the day after the tube has been placed. Do not have a bath for at least 4 weeks until the area around the tube has healed. Make sure the end is closed and clamp applied before washing. Fully dry the area around the tube after.

Can I swim?

Only once the area around the tube has healed. Use a waterproof dressing. Fully dry the area around the tube after.

Can I go on holiday?

The tube does not stop you going on holiday. You may need to take a GP letter and insurance documents with you. Contact the home feeding team for further information.

Will I be able to move freely?

The tube should not restrict your everyday activities. You can cover the tube with loose clothing.

What happens if I become unwell?

If you feel unwell and are unable to give yourself your feed, it is important to keep hydrated. Flush the tube regularly with water to prevent the tube blocking and to keep hydrated. Speak to your GP, nurse or dietitian if you are concerned.

How do I keep my mouth clean?

You will need to keep your mouth and teeth clean by brushing regularly. This is important even if you cannot eat and drink. A mouthwash and artificial saliva spray may help to keep your mouth moist. The speech and language therapist can guide you on this.

Who pays for the feeds?

If you are an NHS patient and registered with a GP, your local health authority will pay for the feeds.

What do I do if I experience any pain, discomfort or issues with my tube site? 

If you experience any pain or discomfort then stop any feed. Contact the community feeding team for further advice. Contact the community feeding team if the skin around the site becomes red and sore or if there is oozing or bleeding.
