Gastric sleeve surgery overview
Bariatric surgery (surgery for obesity) includes several different types of operations. Laparoscopic sleeve gastrectomy or gastric sleeve is a relatively new weight loss procedure that reduces the size of the stomach from a sac to a narrow tube. Weight is lost because of early satiety (the feeling of fullness after eating), largely due to the smaller size of the stomach. Also, some appetite stimulating hormones normally produced by the stomach are reduced by the procedure. Apart from this, the stomach digests calories and nutrients in an almost normal way.
This operation has evolved from other procedures performed in the past. One of these operations, the vertical banded gastroplasty (also known as “stomach stapling”), was abandoned due to poor long-term outcomes. These poor results were due to staple line breakdown or blockage at the tight ring placed around the stomach to narrow the outlet. The sleeve gastrectomy is newer, and constructed differently to avoid these problems. It avoids the use of a restrictive ring, and is not prone to the late staple line problems associated with vertical banded gastroplasty.
The sleeve gastrectomy was first used as an intermediate step toward gastric bypass or duodenal switch. These are more complicated operations with higher risks of complications when done in very obese patients (i.e. BMI > 50-55). The sleeve would be performed first, and then several months after this, when the patient had lost weight, a second operation converted the sleeve to a bypass or duodenal switch. Surgeons using this strategy to reduce risk soon noticed that patients often didn’t need a second operation because they were very happy with the weight loss results achieved by the sleeve alone. More recently, the sleeve gastrectomy has been used as a “stand alone” procedure for weight loss, and in recent years it has become a commonly performed operation for weight loss in New Zealand and around the world.
After surgery, patients start on liquids before moving to a pureed diet while the stomach heals. Several weeks after gastric sleeve surgery patients progress to eating three small meals a day of normal consistency food. Entree sized meals are enough to produce a sensation of fullness, making it easier for patients to limit the amount they eat.
The sleeve gastrectomy is done by laparoscopic surgery, which involves several very small incisions, rather than open surgery, which uses one large incision. Harmless CO2 gas is introduced into the abdomen, inflating it, and creating a space for the surgeon to work. The surgeon introduces a long narrow camera and surgical instruments, and uses these to perform the procedure.
Laparoscopic procedures have the advantages of less pain, a shorter hospital stay, and a quicker recovery, as well as a significantly reduced risk of wound infection or wound hernias. If, for some reason, your surgeon cannot complete the procedure laparoscopically, he can switch safely to the open procedure. The chance of this happening is low and would only be done in your best interests.
Improved health
Bariatric surgery reduces the risk of death from obesity. Many obesity-related conditions, such as type II diabetes, obstructive sleep apnoea, joint pain from arthritis, high cholesterol and high blood pressure, are either completely resolved or substantially improved.
Long-term weight loss
Most patients achieve good to excellent weight loss results following gastric sleeve surgery; typically this is 60 to 70 per cent of excess weight. Patients lose most of their excess weight in the first year and can lose more weight over the next six to 12 months. Weight will usually stabilise after this. There can be some weight regain, but this is usually minor. There is no amount of weight loss that is guaranteed.
Healthy lifestyle changes, with improved diet and regular exercise, lead to a better outcome after the surgery. The laparoscopic gastric sleeve procedure is best seen as a tool that makes these lifestyle changes achievable for most patients.
Anaesthesia for surgery
An anaesthetist is a medical specialist just like a surgeon, requiring the same length of training, and you will have a fully trained specialist anaesthetist for your surgery. The anaesthetist will contact you prior to your surgery to ask you about any previous and current health issues. Please feel free to ask about any aspect of your anaesthesia care. It is important you try to answer all questions fully to enable the anaesthetist to use the best anaesthetic techniques for your surgery.
Specifically, it is very important to tell the anaesthetist about
- any previous anaesthesia problems
- any allergies
- any history of pulmonary embolus (blood clot in the lung) or deep vein thrombosis (blood clot in the leg).
The anaesthetist will arrange for extra tests if they are required to give your anaesthetic safely. If needed, they may ask to see you prior to the day of surgery.
You will usually meet your anaesthetist before your operation on the day of surgery, who will answer any further questions you may have and obtain your informed consent for the anaesthesia. Laparoscopic sleeve gastrectomy procedure requires general anaesthesia: this is a combination of drugs used to put you into a state of controlled and reversible unconsciousness. The anaesthetist monitors you continuously during this time, and you will be given painkillers and anti-emetics (which help prevent nausea and vomiting) while you are asleep. In the recovery room, further medications will be given as needed.
Pain is normally minimal after this procedure, but can be felt in the small cuts made in the abdomen. Occasionally, the gas used to inflate the abdomen can cause pain in the shoulder tip, but this rarely lasts long and is easily controlled. If ongoing pain relief is needed, then a PCA pump (patient-controlled analgesia, ‘Pain Pump’) can be used. You push a button and the pump delivers a dose of painkiller. You cannot give yourself too much; the machine will limit the amount of painkiller it delivers to safe level. Nausea and vomiting can be troublesome for some people but there are many drugs we can use to prevent this. Your anaesthetist will chart a list of drugs for the ward nurses to give, and we would encourage you to use them as required. The nurses can contact your anaesthetist at any time for advice about pain-relief and any other non-surgical problem.
Your anaesthetist will be involved with your care for 2-3 days after the operation in co-operation with your surgeon. He or she takes care of pain-relief, nausea / vomiting and intravenous fluids, as well as managing most medical problems such as diabetes while you are in hospital.
Before gastric sleeve surgery
DAY ZERO
Admission
You will be admitted to hospital on the morning of surgery unless you have specific medical problems that your anaesthetist and surgeon wish to monitor closely overnight. It is understood that you will have had a thorough shower prior to admission, and that you bring along everything you require for your hospital stay. If you have any further questions for your surgeon or anaesthetist, please write them down and bring them with you to hospital. If your operation is in the morning, you should not eat or drink from midnight the preceding day. If your operation is in the afternoon, you may have a light breakfast at 6 o’clock in the morning, but fast after that.
CPAP (Continuous positive airway pressure)
If you currently use CPAP for obstructive sleep apnea, please bring your machine with you to hospital.
Medications
Bring in all medications including over the counter and herbal medications. Don’t stop any medications unless told to do so by your anaesthetist or surgeon.
During the admission process your surgeon, anaesthetist, admission nurse and theatre nurse will see you. This will mean that different people ask you the same questions. This is a safety issue, and although it can be frustrating, it is important. Use this time to ask any questions that you may have.
Once you have been admitted and changed into your theatre gown and TEDs (stockings to prevent leg clots), you will wait in the preoperative area until theatre is ready. A warming blanket is often used at this time to keep you extra warm. A final check between the theatre staff and the admission staff takes place before you go through into the operating theatre.
You will move onto the theatre bed, which is narrow and firm, and a blood pressure cuff, ECG and an oxygen monitor will be attached to you so your anaesthetic team can monitor you closely throughout the procedure. Your anaesthetist will place a cannula (drip) into a vein and ask you to breathe some oxygen through a plastic facemask. Your anaesthetist will then gently send you off to sleep.
After gastric sleeve surgery
DAY ZERO
Recovery Unit
You will wake up in the recovery unit with monitoring attached to you. You will have a cannula (drip) in your arm. Occasionally a drain (plastic tube connected to a container) will have been placed into your abdomen, and occasionally a urinary catheter (tube into the bladder) is used as well. The PCA pump can attach to your drip if required.
Further post-operative care
After you are awake and comfortable you will be transferred to the ward. Occasionally we keep patients in the high dependency unit (HDU) initially. Typically, patients that are larger, older, or with medical problems that need closer monitoring will go to the HDU rather than the ward. Which ever location you are in, your nurse will record your vital signs regularly and give medications to control pain or nausea. You will be encouraged to do deep breathing exercises to keep your lungs healthy, and to move into a chair.
We use several means to prevent clots forming in the legs and lungs (DVT and PE). Early mobilisation is important, and your nurse and the physio will help you with this over your stay. You will also have TED stockings on and a FlowTron machine (inflatable stockings). You may be given injections of heparin (a blood thinner).
You can start to suck on some ice chips or to take sips of water on your first night.
DAY ONE
If not already in the ward, you will move there on day one. You will be encouraged to slowly sip your way slowly through one litre of water over the day. When you are able to manage this amount of water your IV can be removed. Do not try to hurry this; have a cup or water bottle to hand and sip slowly and steadily. If you appear to be managing this, your diet will progress to bariatric free fluids (see nutrition information section).
If you have a urinary catheter, this will be removed when you are moving independently. If you have a drain, this will be cut short with a bag fixed over it or removed to allow you more freedom to move. You will continue with measures to prevent blood clots (as described above).
Your surgeon and anaesthetist will see you, as well as your dietitian and physiotherapist.
It is important that you get up and move around as soon as you are able, so you will be encouraged to walk around the ward. This allows your lungs to fully expand and the circulation to your legs to return to normal. Moving gently and regularly around your room and the ward is extremely important for a rapid and uncomplicated recovery.
Medications for pain and nausea will continue and will change to tablets or liquid forms so that the drip can be taken away. Do not hesitate to ask for a sleeping tablet if you require help to sleep at night.
DAY TWO
Walking will continue to be encouraged. You will continue to wear TED stockings all the time. The FlowTron device will be used when you are not moving around.
All your medications should now be taken orally, perhaps crushed or in liquid form. You should be managing bariatric free fluids by this stage, and you can proceed to a bariatric pureed diet as you are able. Advice on bariatric pureed diet is provided in the nutrition information section.
Most patients, if they are progressing well, will be able to go home on this day. If you have a drain, it will usually be removed before discharge.
DAY THREE
If you did not leave hospital the previous day, preparations will take place for this today. Your diet should be a bariatric pureed diet (see nutrition information section). Walking as much as possible and deep breathing exercises will be encouraged.
Advice on Discharge
You will be reminded to eat 3 meals a day. This must be by the clock, as often you will not feel any hunger. Remember to take small bites and chew, chew, chew. When you feel full, STOP eating.
In the early days you will need to re-learn what your new stomach can manage. Almost every patient will at some stage inadvertently swallow a mouthful of food that is too large or too solid to pass through the sleeve easily. This usually results in an uncomfortable, dull pain behind the breast bone. The best way to manage this circumstance to to simply wait and stay upright. Gravity will eventually help the food to pass. Sometimes the food will be regurgitated. Do not try to push or flush the food down with more food or fluid. This will only worsen the situation. Do not panic, it is almost impossible to do harm to the sleeve by swallowing something that does not go down easily.
Swallowing will become progressively easier over the first week or so after surgery. Most patients can easily tolerate small amounts of puree regularly after a few days.
You will be given a prescription for medications to be taken after discharge.
These include:
- Analgesia for pain relief, usually for up to 2 weeks
- Anti emetic to help with nausea usually for up to 2 weeks
- Anti acid to reduce stomach acid usually for 6 weeks
- Perhaps heparin for prevention of pulmonary embolism
Occasionally you may be prescribed a laxative (such as lactulose) for help with bowel movements.
You should carry on taking your normal medications that you were on before surgery, unless specifically told to stop. Some tablets taken in the first six weeks after your operation may need to be crushed. We advise you continue wearing your TED stockings for 10 days post operation. This is to reduce the chance of blood clots that can form in the legs, and can go to the lungs.
If you have successfully managed to stop smoking prior to your surgery, then you should maintain this after your gastric sleeve operation. Smoking can slow the healing of the stapled edge of the stomach, and cause ulcers and bleeding. It is also important that you refrain from alcohol post surgery until you have got used to your new stomach. When you do want to start alcohol again, do so only in moderation: it can have a more potent effect, and contains a lot of calories.
Follow-up appointments
| One week | You will be contacted by phone around one week after your operation to check on your progress. Use this call to ask any questions you may have. |
| Two weeks | You will be asked to make an appointment to see your surgeon in two – four weeks after surgery. Make sure you keep this appointment. |
| Four weeks |
Please make an appointment to see your dietitian |
| Six weeks |
Appointment to see your surgeon. Some patients may find it helpful to see a psychologist at this time. |
| Three months | Appointment to see surgeon (or nurse practitioner) and dietitian. |
| Six months |
Appointment to see surgeon (or nurse practitioner) and dietitian. |
| One year |
Appointment to see surgeon (or nurse practitioner) and dietitian. Many patients will be able to be discharged at this time. Your GP will asked to arrange blood tests to check your vitamin levels on an annual basis. |
| Every year |
Appointment to see surgeon (or nurse practitioner) if required. |
You will often be asked to obtain specific blood tests in the week before an appointment. Other medications, such as calcium, vitamin D and iron, may be prescribed at these follow-up visits.
Potential complications
All surgery has risks, and as any stomach operation for obesity is considered major surgery, it has significant risks associated with it.
People have died from having operations for morbid obesity. It happens rarely, but the risk can never be removed completely. If you are older, or you already have certain health problems related to your obesity, your risk may rise. Heart attacks after the operation or clots that form in the leg veins, which then pass to the lungs, can cause death in morbidly obese people after surgery. This risk is between 1 in 500 and 1 in 100. Thorough precautions are taken during surgery and your hospital stay to minimise these risks, but they cannot be eradicated altogether.
Other problems that can occur after gastric sleeve surgery include pneumonia and wound infections. Some of these are relatively minor and do not have a long-term effect on your recovery. Other complications may be more significant and require a longer hospital stay and recovery period. Antibiotics at time of surgery, deep breathing exercises and early mobilisation after surgery are some of the measures taken to reduce the risks of these complications.
After a gastric sleeve procedure, all patients should take multivitamin supplements lifelong, and some need to take iron or calcium supplements as well. Sometimes one or other of these supplements are best given as an injection.
Complications that can occur with gastric sleeve surgery are listed below. This list is long, and although most patients have no complications, or minor complications only, please take note and ask your surgeon and team any questions that will help you to understand the risks associated with obesity surgery.
The most serious complication of sleeve gastrectomy is a leak in the staple line where the stomach has been removed. If this does occur it will usually be within a few days of surgery.
Patients often ask “how will I know if I have a leak?”. Usually the patient will experience quite severe pain in the upper abdomen that comes on rapidly and is often worse very soon after swallowing food or fluid. The nature of this pain is such that it is immediately apparent to most patients that something is seriously wrong. In this situation contact your surgeon without delay.
During gastric sleeve surgery
- A larger incision may need to be made because of technical difficulty with keyhole approach
- An injury to the bowel or other organs from insertion of keyhole instruments
- Bleeding from blood vessels or injured organs
- Technical difficulty leading to change in operation strategy
- Complications related to placement of intravenous and arterial lines. This includes bleeding, nerve injury, or pneumothorax (collapsed lung)
- Nerve or muscle injury, usually temporary, related to positioning during surgery
- Allergic reactions to medication, anaesthetic agents or prosthetic devices
After gastric sleeve surgery
- Death. Rate between 1 in 500 to 1 in 100
- Leak from staple lines. Rate between 1 to 2 in 100. May require further surgery or lead to sepsis
- Bleeding. Rate around 1 in 100. May require transfusion or further surgery
- Infection at keyhole incisions, or deep within the abdomen. A serious infection is often called sepsis. This is uncommon but can lead to further surgery, a longer hospital stay organ failure or death
- Deep vein thrombosis (blood clot in the leg veins). These can occasionally travel to the lungs (pulmonary embolus). Rate around 1 in 100.
- Pneumonia or other breathing problems. The worst of these is respiratory failure, which is the inability to breathe adequately after surgery, and may require support of breathing in an intensive care ward
- Heart attack or abnormal heart rhythm
- Stroke
- Pancreatitis
- Urinary tract infection or injury to the urinary tract from catheter insertion
- Colitis (inflammation of the colon), usually due to antibiotics used in surgery
- Constipation
In the longer term
- Troublesome symptoms may include abdominal pain, change in bowel pattern, tiredness, bloating, nausea or vomiting
- Narrowing at the middle of the stomach (known as hour glass stomach). May require stretching with a balloon or rarely surgery
- Excessive or inadequate weight loss. Rarely requires further surgery
- Dehydration or imbalance of body salts, usually from inadequate fluid intake, infrequently requires admission to hospital
- Inflammation of the remaining stomach or oesophagus
- Gall bladder disease, usually from gallstones that form during rapid weight loss, Can require surgical removal of the gallbladder
- Hernias at the site of incisions
- Psychological problems can include depression, adjustment disorder, relationship difficulties and rarely suicide
- Liver disease or failure. Can occur if there is underlying liver damage that is worsened by weight loss or surgery
- Hair loss from protein malnutrition. This usually resolves within a few months of surgery and is usually only noticeable to the patient
Nutritional information
After gastric sleeve surgery you will need to make changes to your eating patterns. The diet after surgery progresses from a liquid diet to a pureed diet to a soft diet and then a modified diet. This progression is designed to allow your body to heal. It is very important that you follow the diet progression to maximise healing and minimise the risk of complications.
Before gastric sleeve surgery
For two to six weeks before your surgery you are required to follow a low calorie diet. The programme followed is Optifast or Dr Mcleods. Your dietitian and surgeon will advise on the amount of time you will need to follow this diet.
Why is it necessary to lose weight pre-surgery?
- To lower body fat levels for better access for the surgeon i.e. safer surgery
- To reduce the size of your liver which would otherwise be in the way
- Greater ability to adapt to post-operative dietary requirements
- Reduced operating time and post operative risks
- Improved physical function and mobility post-surgery
What is Optifast?
- Very low calorie diet (VLCD) that is < 800kcal per day
- Nutritionally complete. (All the protein, vitamins and minerals that you need)
- Involves three “meals” per day, which can be milkshakes soups or bars
How does it work?
- Each VLCD meal is taken at usual meal times and provides all essential nutrients
- You need to drink at least 2 litres of the following fluids per day:
- Water
- Diet soft drink
- Black tea or herbal tea without milk or sugar - A maximum of 2 cups of low starch vegetables are allowed per day
- Replacement fibre – 1tsp of psyllium or equivalent per sachet of optifast eg Metamucil or Benefibre
- Please see attached “foods allowed” lists below for more information
If you are having trouble with this diet or having symptoms such as nausea, please call your dietitian, surgeon or your GP.

After gastric sleeve surgery
DAY ZERO (evening of surgery)
- Ice to suck, sips of water
DAY ONE
- 1 litre of water (slowly), progressing to bariatric free fluids (room temperature clear/smooth soups, Optifast, tea/coffee, low fat smoothies, low sugar)
DAY TWO
- Bariatric free fluid diet, progress to bariatric pureed diet as tolerated (very small amounts of puree/mashed food only half a teacup at a time at most)
DAY THREE TO WEEK THREE
- Progress to bariatric pureed diet as you are able
WEEK FOUR onwards
- Small meals of soft food that is high in protein and low in fat and sugar
General information
During all of the above stages and when you have recovered fully from surgery it is crucial that you
- AVOID liquids with meals (do not drink 30 mins pre and post eating)
- Drink between meals and aim for six to eight glasses fluid per day
- Follow a general healthy diet, low in fat and sugar
Constipation
- Because you are eating less constipation may be a problem. Keeping up with your fluid intake, and occasionally using a gentle laxative will help with this. Most patients will not feel the urge to have bowel movement for several days after surgery. This is because you will be taking very little food and is entirely normal.
Handy hints
- If you try to eat too much too quickly vomiting or regurgitation may occur.
- Do not consume liquid calories such as fruit juice, soft drinks, or milkshakes.
- Eat slowly, chew all food well and take time with your meals.
- Ensure you have an adequate protein intake. Protein should be eaten before carbohydrates (starchy) foods.
- As soon as you are home after your surgery start taking a multivitamin daily such as “Centrum”.
Puree diet
- To be followed until three weeks after your surgery
- Eating too much can result in complications before healing has occurred.
Important points
- Eat slowly
- AVOID very hot or very cold foods
- DO NOT drink within 30 minutes of meal times
- It is normal to be managing only very small amounts during this phase. Eating with a teaspoon from a small plate is a good idea.

Handy hints
- Introduce more solid foods after a few weeks e.g. salads, red meat
- AVOID bread and instead have low fat crackers e.g. rice crackers, cruskits
- Look for <5 g fat per 100g - Small amounts of toasted vogels bread can be eaten. AVOID soft white breads
- Continue to chew food well and take your time eating
- AVOID fluids with meals
- Do not over eat as this will make you uncomfortable and may cause vomiting
- Continue to eat regular meals and select healthy food options to optimise your continued weight loss
- You will need to make sure that your meals are nutritious and include all the nutrients your body needs
- Choose foods that you enjoy and take time to savour their flavours
Food to include at each meal
Protein
You need to include low fat protein at each meal to ensure you maintain your muscle stores and loose fat stores e.g:
- Lean red meat 2-3 x per week e.g. lean mince, eye fillet
- Fish and chicken (no skin)
- Low fat dairy products e.g. trim milk, low fat yoghurt and cottage cheese
- Tofu, beans and lentils e.g. baked beans, hummus, kidney beans
Hair loss (temporary) can be a problem if there is inadequate protein in your diet. Using protein powders (muscle building formulas) in fruit smoothies and purees can be a good way to increase your protein intake. Protein helps to keep you feeling satisfied for longer.
Fruit and Vegetables
- Fresh, frozen or canned vegetables. AVOID hard seeds and pips
- Fruit that has been peeled and membranes removed.
Carbohydrate/Starchy Food - 2-4 serves per day
- 1 serve = ½ cup pasta/cereal, 1 slice bread, 1 egg sized potato
- Potato, bread, rice, pasta and cereals should be eaten in very small amounts only
- If you are having bread, use wholegrain varieties (e.g. Vogels) and toast it as this will fill you up more
- Protein foods should take priority
Fluid
- 6 – 8 glasses fluid per day (do not include coffee, alcohol or caffeine drinks).
- AVOID full strength juice, cordials, high calorie fizzy drinks, milkshakes etc
Fats
- Use very minimal margarine or preferably none
- Vegetables can stir fried with a teaspoon of olive oil
- Generally avoid oil in cooking. Grill, bake, boil, stir fry or dry roast
- AVOID fatty meats e.g. sausages, luncheon sausage, salami
Handy hints
- Order entree size meals when dining out
- Continue to eat regular meals and select healthy food options to optimise your continued weight loss
- Aim to exercise 45-50mins five days per week. This should be continuous cardio type of exercise - rather than weights - of enough intensity to “raise a sweat”
- Brisk walk, cycle, cross-trainer, aqua jogging or swimming
- Weight-bearing exercise is best for weight loss maintenance
Healthy lifestyle choices
There are several long-term habits that you should adopt to get the most out of your surgery. The first post-operative year is a critical time that must be dedicated to changing old behaviours and forming new, lifelong habits. Lack of exercise, poorly balanced meals, grazing or snacking, and drinking carbonated drinks are frequent causes of not achieving or maintaining weight loss.
To maintain a healthy weight and to prevent weight gain, you must develop and keep healthy eating habits. You will need to be aware of the volume of food that you can tolerate at one time and make healthy food choices to ensure maximum nutrition in minimum volume. A remarkable effect of bariatric surgery is the progressive change in attitudes towards eating. Patients begin to eat to live; they no longer live to eat.
Obesity cripples the body. As weight is lost, the burden on the bones, joints and vascular system is decreased. Given proper nutrition and physical motion the body will rebuild its broken framework. The most effective way to heal the body is to exercise. People who successfully maintain their weight exercise daily.
Exercise and the support of others are extremely important to help you lose weight and maintain that loss following gastric sleeve surgery. Exercie improves your metabolism.
- You can take walks at a comfortable pace almost immediately after surgery.
- You can generally resume higher impact exercise six weeks after the operation.
- Attending a support group or exercising with a friend can boost your confidence and help you stay motivated.
A physiotherapist will see you whilst you are in hospital. They can give you initial advice regarding exercise. Your GP can give you information about groups or programmes in your area. There is a lot of support around you; ultimately it is up to you to make use of it.
10-point plan
- Do not drink liquids within 30 minutes of meals.
- Eat three small, protein-focussed meals per day at regular times, sitting at a table.
- Stop eating when feeling full or if feeling discomfort.
- Always cut food into small pieces, eat slowly and chew food very well, savouring your food. Use a teaspoon.
- Concentrate on eating protein rich foods such as fish and seafood, cheese, eggs and poultry. Eat protein foods first before any other food.
- Do not snack between meals.
- Avoid sweet food (lollies, chocolate, and high-sugar drinks), or very rich or highly processed food.
- Sip liquids slowly, drinking at least half a cup every hour between meals to avoid dehydration.
- Minimise alcohol intake as it is high in calories; the effects may be felt much more quickly; and it tends to lead to eating foods that are less healthy.
- Take a multivitamin supplement every day, and other supplements if required.
