Enhanced Recovery after Bariatric Surgery (ERABS)

Laparascopic Roux –en-Y gastric bypass

A gastric bypass is where surgical staples are used to create asmall pouch at the top of the stomach.

The pouch is then connected to your small intestine, missing out (bypassing) the rest of the stomach.

This means it takes less food to make you feel full and you will absorb fewer calories from the food you eat.

Laparascopic Sleeve Gastrectomy

A sleeve gastrectomy is where a large part of the stomach is removed so its much smaller than it was before.

This means you cannot eat as much as you could before surgery and you will feel fuller.

 

 

Before your surgery

We expect you to be in hospital for approximately 12 – 24 hours after your surgery – you will be discharged once you have met your discharge criteria which is;

• Drinking fluids adequately (roughly 1.5 litres over 24hrs.
• Pain is reasonably well controlled on the pain medication you are given.
• Nausea reasonably well controlled on anti-sickness medication.
• Medically fit for discharge (surgeons will review and make this decision).

1. Please arrive at the hospital as advised in your letter.
2. You will be required to fast (stop eating, including no milk) for six hours prior to surgery you can have clear fluids up to 2 hrs before surgery.
3. You have been prescribed medications to take prior to the operation. It is extremely important that you take these medications as prescribed and at the right time. If you have any concerns about taking these please contact Obesity Services.
4. Any other regular medications that you take should be taken as normal, unless the surgeon or anaesthetist have advised you not to (e.g. aspirin/warfarin are usually stopped before surgery).
5. It is very important you follow the low calorie liquid diet for two weeks before surgery. If you can’t drink milk an alternative plan should have been agreed with you. If you have diabetes please monitor your blood glucose and contact the obesity team if they go below 5 or above 9.

Lifestyle improvements

Smoking cessation and limiting alcohol intake

Patients who smoke are at higher risk of complications such as leaks, perforations and stomach ulcers. Therefore we strongly insist that you should quit smoking at least two weeks before your surgery. If you need help with this speak to your GP or your local stop smoking service.

Oral Hygiene

Studies have shown that maintaining good oral hygiene before your surgery can help reduce the risk of some post operative infections. Brushing teeth twice a day is good practice leading up to and after your surgery. If you have any dental concerns we would advise a trip to your dentist and also make them aware of your upcoming surgery.

Increasing exercise

We encourage you to try to increase your level of exercise prior to surgery. Any improvement is good and should be within your own capabilities.

Walking is a great form of exercise which helps boost circulation, builds muscle tone and increases your heart rate which can all help your recovery from surgery.

Any exercise should be continued after surgery but please check with your surgeon before undertaking anything strenuous e.g. lifting, swimming, vacuuming, carrying heavy bags etc to reduce the chance of developing a surgical hernia.

Chair exercises – Sit to stand

These are particularly useful if you have lost muscle mass in your legs or your mobility is poor and you need to strengthen your legs.

Deep breathing exercises

Being able to breathe deeply and comfortably after your surgery is important as this will help to reduce the risk of a chest infection. You should begin to practice these now.

Repeat every hour, 10 times a day!

• Take a big breath in through your nose
• Expand your ribcage as you inhale
• Hold for 3 seconds
• Breathe out slowly through your mouth
• Use a supported cough to clear secretions
• And repeat!

Preparing for your stay in hospital

Prepare for discharge before you come in

When you leave the hospital, you may return to your home or stay with family or friends. You do not necessarily need someone to stay with you if you normally live alone.

Please ensure you have a suitable environment to be discharged to before yo u come into hospital. If you require advice or assistance with this please contact your GP or local Social Services prior to admission .

There are a f ew simple things you will need to do prior to your admission which may make things easier for you when you return home.

• Have a stock of high protein, nourishing fluids ready as listed in Phase 2 of your post op diet.
• Ensure your house is free of clutter so it is easier and safer to move around.
• Changing bed linen is often a good idea.
• Arrange for a repeat prescription of your regular medications (if any).
• Have a supply of paracetamol at home for managing mild pain.
• Please ensure you have transport arrangements for getting home e.g. friends and/or family. If you arrived by hospital transport please ensure you have made arrangements for your return home when booking your admission journey.
• If you need a taxi ensure you have sufficient funds to pay for it.

General Complications

One of the main aims of the Enhanced Recovery Programme is to reduce the risk of complications after surgery. It is important you play an active role in your own recovery to reduce your chances of developing certain complications.

Blood Clots (Deep Vein Thrombosis)

The longer you are in bed or that you are not moving around often after surgery, the greater the risk of blood clots forming. Which is why we encourage you to start circulation exercises in bed when you wake from your surgery and on the ward to get up as soon as possible after the operation only with supervision by a healthcare professional until you are safe on your feet.

Preventative measures include:

• Whilst in bed, do your deep breathing exercises routinely (on page 8)
• Do your circulation exercises:
  – Early mobilisation – When you arrive back to the ward you should get up and out of bed once the nurse is happy for you to do so.
  – Anti-embolism stockings
  – Blood thinning medication
  – Drinking fluids as instructed by the nurses and doctors

Chest infections

Everyone is at risk of developing a chest infection after surgery and this risk is increased further if you have chest or lung disease or are a smoker.

Deep breathing exercises are key following abdominal surgery to help get the air right to the bottom of your lungs and therefore can help prevent an infection occurring. Also aiming to be out of bed most of the day is very beneficial.

Nausea and Vomiting

This is one of the main side effects/complications of bariatric surgery.

Usually you will experience some nausea after your surgery and should be given some anti-sickness medication to help control this.

If you are still experiencing nausea or are vomiting and cannot tolerate fluids orally whilst in hospital, please ask your nurse for some anti-sickness medication.

Expect some degree of nausea after you go home, this can be normal. You may require further anti-sickness medications to help with this at home. If you cannot tolerate any fluids or are vomiting you must speak to the obesity team as soon as possible for advice – see the numbers at the back of this booklet.

Pain control following surgery

How is pain assessed?

After surgery, you MUST be able to do the following things comfortably in order to help you recovery quicker;

• Deep breathe
• Cough
• Get in and out of bed
• Walk

You should expect some general discomfort following surgery and on drinking to begin with. This will improve gradually at home. You will be given pain relief by your nurse. If you cannot do any of the above due to pain then you must ask your nurse for some extra pain relief which is called ‘PRN’ or ‘Top up’ this will not be given automatically unless you ask for this.

Pain Score                       Description
0 (none)                               No pain at rest or on movement
1-3 (mild)                             No pain at rest but slight pain on movement
4-7 (moderate)                   Intermittent pain at rest or moderate pain on movement
8-10 (severe)                       Continuous pain at rest or severe pain on movement

If you suffer from chronic pain your normal, everyday pain score may already be high so this should be taken into account. If you are on a lot of regular pain medication already then please take as indicated pre-op and ensure you are clear on the instructions post op for any temporary change in dosing. Bring these in with you to hospital and give them to your nurse on arrival to the ward.

Things to bring in with you…

• This booklet!
• A small supply of non-perishable, high protein fluids as per Phase 1 of your diet e.g. OXO cubes, squash, small tubs of custard etc.
• Your CPAP machine – if you use one
• Comfortable day clothes to wear on the ward including footwear
• Nightwear
• Sleep aids e.g. eye masks, ear plugs
• Personal hygiene items (washing, shaving etc.)
• Any medications you are on especially any pain medications as these should be continued after your surgery in most cases and you will be advised by your surgical team. (Please ensure these are in original boxes and that you give them to your nurse on arrival to the ward – do not take any of these unless instructed to by your nurse / doctor).
• Wifi is available throughout the hospital which you can use with your own personal devices, although please be aware, these remain your responsibility.
• Books, magazines personal entertainment devices and a small amount of money if you require anything from the hospital shop.

Admission to Hospital

Day of Surgery

You will receive a letter advising you of your date and time of surgery along with fasting instructions. Please read and follow these carefully. Please note that milk is classed as food and should be stopped 6 hours before your surgery.

• Please ensure you are well hydrated when you come in for your surgery. You should aim to drink between 1.5 – 2 litres of any fluids in the 24 hours before your surgery.
• You will be given a pair of anti-embolism stockings to wear during surgery (unless contra-indicated) which help prevent blood clots forming.
• You will be changed into a hospital gown and you will have to remove or tape any jewellery and remove any dentures and glasses. These can be removed at the last minute if you need them.
• You will be seen by an anaesthetist who will discuss your anaesthetic plan. Please inform them of all the medications and analgesia (if applicable) that you are currently taking.
• Then you will be escorted to theatre by hospital staff.

Day 0 – After your surgery

In the Recovery area

Immediately after your operation you will spend time in the recovery area until a bed space becomes available on the ward.

When fully awake you should begin your deep breathing and circulation exercises in bed and start your fluid intake – unless otherwise indicated by your surgeon.

You should start by drinking approximately 30mls of water (a small medicine cup size) every 10-15 mins – so 4 of these in one hour.

Once you have managed this, you can start to increase the amount you drink and can progress to squash, tea, coffee etc (see page 20 for high protein liquids you can have).

Tepid fluids are best rather than too hot or too cold.

You will be given a Vitamin B12 injection – you will need this every 3 months for life.

On the ward (day 0 until discharge)

You may have some fluids running via a drip in your arm. This will be removed as soon as you are drinking adequately.

You should now get up and move out of bed. Please wait until the nurse checks your blood pressure etc and a staff member should help you do this for the first time. The best time to do this is when you need the toilet.

Getting out of bed and moving around as soon as possible will help to prevent DVTs and chest infections.

Walking also helps get rid of the trapped gas you can have following your surgery which can cause some shoulder tip pain.

If you feel nauseated, please let the nursing staff know so they can give you some anti-sickness medication as soon as possible so you can continue your oral fluids.

It is expected you may have some discomfort following your surgery. You will be given pain relieving medication to help with this. You can also ask for extra pain relief should you require it, it is called PRN or Top Up.

You need to ask your nurse for this as it will not be given automatically.

If you use a CPAP machine at home you should have this with you. You need to use this any time you are asleep after surgery, especially the evening you come back from your surgery.

Short term Discharge Medications

In addition to your life long medications you will be given; Blood thinning injections which reduce the risk of blood clots for 14 days after your surgery.

Lansoprazole fastab helps reduce stomach acid, prevent reflux, indigestion, nausea and promote healing. You should take this for three months.

Senna will help manage constipation whilst on a fluids only diet.

Going Home

This should be the next morning after your surgery providing you have met the discharge criteria which is;

• You are medically fit i.e. your blood pressure, heart rate and temperature are within normal range for you.
• You are drinking adequately (aiming for 1.5 litres over 24 hours)
• Your pain is reasonably well controlled on the pain relieving medication you are on in hospital.

Please ensure you have your transport arrangements made prior to admission. Take any painkillers you are due to have before you set off home as being in a car for a while may be uncomfortable.

If you have travelled some distance then it is sensible to make regular stops to get out and move around and make sure you stay comfortable.

If you have anti-embolism stockings on, these should be worn until your mobility is back to your normal, ensuring you are taking them off for no more than half an hour each day to check, wash and moisturise your skin.

If you are diabetic and on medication, your new medication regime should be explained to you before discharge.

You should avoid flying for 2 weeks after your surgery.

You should not drive until confident and comfortable to do an emergency stop without hesitation. Also, please check with your insurance company.

General Advice for after discharge

In the days and weeks after surgery increasing pain around your tummy, uncontrolled vomiting, being unable to drink, increasing shortness of breath, fever and palpitation may be signs of problems. You should immediately contact us on the number at the back of this booklet.

• Please ensure you understand your medications given to you on discharge.
• Use a small plate or ramekin dish to control your portion sizes.
• Staying well hydrated is important, aim for at least 1.5 litres of fluid per day. Try carrying a bottle of water with you and take frequent sips. Avoid drinking with food as the fluid can fill up your stomach.
• Remember to take all the vitamin and mineral supplements. It takes around six months to adjust to your new diet. If a food does not agree with you then avoid it for a little while and try it again 1-2 months later.
• A meal should take 15-20 minutes to eat. It may take longer to start with, but try not to spend more than 30 minutes at each meal.
• As you move through these stages, you should continue to have your bowels open regularly. You can use senna as needed.
• You should also be passing a normal volume of urine, which should be a pale straw colour. If it is concentrated (dark in colour or strong smelling), contact your Dietitian for advice.

It is important to come to your follow up appointments at 6 weeks, 3 months, 6 months, and 12 months. If you have any concerns about attending the clinic let the bariatric team know to arrange another time for your appointment.

If you cannot commit to this regular follow up you should not consider surgery.

Dumping syndrome

Eating foods and drinks high in sugar or fat can result in the symptoms of ‘Dumping Syndrome’. These might include nausea, sweating, dizziness and diarrhoea. Some people are just more sensitive to this than others. Be especially careful if you are eating out that you select low fat, low sugar foods and drinks.

• You may struggle to find high protein liquids that you can tolerate, especially if you are particularly sensitive to dumping syndrome. Try diluting Complan, Slimfast or other commercial milkshakes with more milk to reduce the sweetness of these drinks. Remember to sip them slowly – a tumbler of fluid should take you an hour to drink.
• Choose low fat, low sugar foods and drinks, have smaller amounts, and remember not to drink with your meals. If you are eating ready meals, have those with less than 5% fat (5g fat per 100g of ready meal).
• If you are having frequent episodes of dumping syndrome, it may be helpful to keep a food diary for a week. This could help you to identify foods/ drinks which are causing you problems.

Phased reintroduction of food

Phase 1: from surgery until Week 3

• When you are fully awake you can begin to drink clear fluids – check first with the recovery staff.
• If you are managing water/clear fluids then you can move onto free fluids. Tea/coffee, milk, clear soup etc progressing to your nourishing high protein fluids
• Drink slowly and regularly.
• Aim for at least 1.5 litres of fluid per day
• On a liquid only diet it is important to ensure that the liquids you choose provide you with enough nourishment and protein to ensure you are not losing muscle mass.
• These nourishing fluids should be your first choice over those with no nutritional value e.g. water.

Frequently Asked Questions (FAQ’s)

Struggling to drink?

You may find it difficult to drink enough fluids. A lot of people feel full after only a few sips. Take a bottle with you wherever you go – sip little & often in between meals.

If you feel pain or pressure on drinking or you experience reflux or vomiting, you may well be drinking too much, too quickly – so slow down!

Constipated?

This may happen for the following reasons– you will be on a liquid diet initially with less fibre; you will be eating and drinking much less and some medication will also slow your bowels down. Try to drink more and gradually build up your daily fluids.

You could have some stewed or tinned fruit every day. Fybogel sachets are not recommended as they swell in the stomach.

Can I start to exercise to help my general fitness?

You should wait until the first follow up with your surgical team (this is approx. 6 weeks post op) before you go to the gym or swimming and until this time you must also avoid any heavy lifting.

It is really important that you gradually build exercise into your life in the long term. You should begin gradually and walking at a good pace is a good place to start. Some sit to stand exercises can be good to strengthen leg muscles and increase your heart rate gently.

When can I start to try to become pregnant?

It is recommended to wait a minimum of 18 months.

Significant weight loss can improve fertility so use your preferred method of contraception during this time.

If you do become pregnant please inform the obesity team and your GP as you will need monitoring more closely and you must attend your follow up appointment. We can provide info on this to your GP / Midwife / Obstetrician.

What happens if I do not take my supplements?

It is essential that you take the iron, calcium and multi-vitamin supplements for the rest of your life as you will no longer naturally absorb these from your diet. If you are struggling to take these for any reason, please discuss this with your Dietitian or GP. Your GP may be able to prescribe alternative supplements.

Why is my poo black and runny?

The iron supplement can affect your bowels and commonly causes dark/black poo and taking a Vitamin C tablet alongside the iron supplement may help. You may also tolerate an alternative iron supplement better, please discuss with your Dietitian and your GP.

What is my expected weight loss?

In the first weeks after your surgery you are likely to experience quite rapid weight loss as you adjust to your new diet and stomach size. Slow, steady weight loss of 1-2 lb (½ – 1 kg) per week is healthy weight loss. Please remember, everyone is different!

Weight loss can slow down and this can be disheartening. Rapid weight loss can lead to muscle loss as well as fat loss. This is one of the reasons why we ask you to ensure your diet contains drinks and foods high in protein – so that you limit the muscle loss as much as possible. It is not healthy to continue to see a rapid weight loss.

You are more likely to keep this off in the long term.

Try to weigh yourself no more than once a week to keep an eye on your weight. It is normal to have weeks where you may not lose any weight, even in the early months post surgery.
