Gastric Sleeve Surgery

Gastric Sleeve Surgery for Weight Loss

 

Gastric Sleeve Surgery, also known as sleeve gastrectomy, is a weight loss operation which was developed to treat obesity and has become the fastest growing weight loss surgery procedure. It is becoming a more common option for patients hoping for significant weight loss in a straightforward procedure that doesn’t require the maintenance and potential long-term complications of a Gastric Band.

If you are overweight (BMI 35+ with additional health problems) and have tried non-surgical weight loss methods unsuccessfully, then you may wish to consider a surgical option.

Belfast’s Kingsbridge Private Hospital offers surgical solutions to help aid those who are seeking to achieve sustained, long-term weight loss.

 

What is a Sleeve Gastrectomy?

Sleeve Gastrectomy is a life changing operation. It is carried out to help people who are overweight lose weight and improve their general health. It should also reduce the associated health risks with obesity including high blood pressure, diabetes, arthritis, breathing problems and asthma.

The Sleeve Gastrectomy will make the stomach smaller and, therefore, patients reduce the amount they eat at meals which in turn will aid significant weight loss. 

How does Gastric Sleeve Surgery work?

The surgery is performed laparoscopically, otherwise known as keyhole surgery, under general anaesthetic. Patients should, therefore, make a speedy recovery and any pain experienced should be manageable with pain killers.

The operation involves removing around 75% of the stomach, leaving behind a narrow “sleeve” which becomes the new stomach. The remaining stomach is a tubular pouch and has a much smaller volume than the original stomach, thus a patient cannot consume as much food post-operatively.

In addition to a reduction in the amount of food, and thus calories a person can consume, it has been realised that sleeve gastrectomy induces changes in the body’s response to gut hormones after eating. Hormone signals from the brain appear to be altered and, therefore, patients are likely to feel fuller, faster but by eating less.  

The Kingsbridge Hospital dietician will provide you with a personalised assisted eating plan through which you will be encouraged to reduce your portion sizes and follow a low-fat, low sugar diet. You should expect to see noticeable results within the first few months. 

 

Why Choose Gastric Sleeve Surgery?

There are a number of weight loss surgery options for patients who wish to undergo a surgical procedure to aid weight loss. So why choose to have Gastric Sleeve Surgery rather than, say, gastric band surgery?

Studies have demonstrated that complication rates with Gastric Sleeve Surgery are low and weight loss was just as good, if not better, than a gastric bypass. Additionally, the surgery took less time and was less complicated to perform with no requirement for the follow up regimes associated with gastric bands.

Research has shown that the hormone ghrelin which leads to feelings of hunger was significantly reduced in gastric sleeve patients. It’s believed that the area of the stomach removed during gastric sleeve surgery produces much of the hormone ghrelin. While gastric bypass patients experienced less hunger, it seemed to be more pronounced in gastric sleeve patients.

Patient feedback has also indicated they were very satisfied with the results of the procedure. Following surgery patients reported they weren’t getting the hunger pangs that were once commonplace pre-procedure.

 

Gastric Sleeve Surgery - The Benefits for Patients

Gastric sleeve surgery has considerable benefits from a patient perspective, including:

 Less surgical time compared to gastric bypass.

 Surgery is performed laparoscopically and involves only a short hospital stay.

Straightforward procedure with low post-operative complication rates

 By removing a portion of the stomach largely responsible for the hunger inducing hormone ghrelin many patients experience a reduction in hunger.

No need to re-route intestines as with gastric bypass.

Technically, an easier operation to perform than gastric bypass with similar long term weight loss and rates of resolution of obesity related conditions such as Types 2 diabetes.

 Unlike the Gastric Band which requires regular visits to the doctor for adjustments, the gastric sleeve procedure does not need any post-surgery adjustment.

Unlike Gastric Band Surgery which involves placing a silicone band around the upper area of the stomach, Gastric Sleeve Surgery requires no additional devices to be attached to the stomach.

Weight loss as a result of Gastric Sleeve Surgery tends to occur over an 18-month period compared with 3 years for Gastric Band patients.

Sleeve Gastrectomy or Gastric Band Surgery?

Patients must follow a disciplined routine that incorporates exercise and healthy eating into their lifestyle to ensure success with the Gastric Band.

Weight loss tends to be more successful with gastric sleeve and gastric bypass surgery than with gastric band surgery. Many experienced weight loss surgeons will have plenty of experience of patients that lose little or no weight following Gastric Band surgery.

However, these poor outcomes are principally due to the difficulty some patients have adhering to the major lifestyle changes that need to be followed rather than due to a failure with gastric band surgery itself.

 

Gastric Sleeve Patient Pathway

Prior to going forward with sleeve procedure, our patients have to engage and successfully complete our tailored weight management programme and pre-surgery diet.  The aim of the programme is to help you identify any obstacles which might result in you not having the maximum success from your operation.  In addition, we also want to help you to bring about lifestyle changes which will ensure that you can get the maximum benefit from your sleeve gastrectomy.

Expected Recovery Following Gastric Sleeve Surgery

Recovery from gastric sleeve surgery varies from patient to patient. Typically, our patients will spend two nights the Kingsbridge Private Hospital

You will be provided with detailed guidelines to follow on your discharge which contain post-surgery instructions for best recovery.

Depending on the nature of your work, you can typically return within 4 weeks. Most patients are back to full strength between 6 to 8 weeks after surgery.

 

Post-Operative Gastric Sleeve Care

One of the main benefits of Gastric Sleeve Surgery is that it does not require any follow-up procedures.

Gastric sleeve surgery doesn’t require the regular band adjustments that are required following a Gastric Band procedure. However, it does require on-going care by the patient to ensure lasting weight loss.

This essentially requires maintaining diet and exercise discipline. The success of your surgery will be dependent on you maintaining the lifestyle changes we will suggest prior to surgery.  Currently, we recommend completing 150 minutes of dedicated exercise per week in conjunction with a controlled diet.

It’s vitally important to adhere to the new diet guidelines. So introduce more vegetables, fruits, lean protein sources and whole grains while reducing unhealthy carbohydrates (bread, pastas).

Whatever type of weight loss surgery is carried out the patient should ensure they get enough vitamins, including Multivitamin with Minerals, Iron, Calcium Citrate,Vitamin B12 and Protein Supplements.

It’s always important to talk to your doctor and follow their advice.

Average Weight Loss With Gastric Sleeve Surgery

How much weight should you expect to lose?

Gastric sleeve surgery will help you lose weight quickly. However, like any diet, there can be fluctuations in the pace of weight loss.

Patients can expect to lose between 55% and 65% of their excess weight (excess weight is weight, is your weight above a BMI of 25) in the first 18 months. At 5 years post operation, both sleeve gastrectomy and gastric bypass procedures have a similar excess weight loss rate at around 50% excess weight. This is however dependant on the patient being compliant with recommendations relating to both diet and exercise.  

The amount of weight you can expect to lose depends on a number of factors. It is important make lifestyle changes such as following a low-fat diet and increasing exercise to ensure you lose weight and keep it off. The size the surgeon makes the new sleeve can also make a difference in overall weight loss.

Gastric sleeve patients will lose, on average, about 55-65% of their excess weight. Some patients can lose more or less than 60%.

The tables below provide a guide of how much weight you can expect to lose two years after gastric sleeve surgery.

The calculations are based on average weight loss for men and women. To lose the average amount of weight, you’ll need to follow your surgeon’s pre-operative and post-operative guidelines.

Resolution Of Obesity Related Conditions

Sleeve gastrectomy can reverse some obesity related co-morbidities. Typical outcomes for weight loss surgery one year after surgery are as follows:

Type 2 diabetes - 75% of patients who have had surgery will be off all medications and have a normal blood sugar. The remainder will see a considerable improvement in their blood sugar control.

Hypertension (high blood pressure) - 70% of patients will see a considerable improvement in their blood pressure and be able to come off all medication at one year following sleeve gastrectomy.

High cholesterol (dyslipidaemia) - 80% of patients will see an improvement in their lipid profile one year following sleeve gastrectomy.

Sleep apnoea - 85% of patients who suffer from sleep apnoea will experience significant improvements to their condition following weight loss as result of sleeve gastrectomy.

You should consult your GP and discuss the outcomes of your weight loss prior to stopping any treatments or medication you are currently taking.

Gastric sleeve surgery is available at Kingsbridge Private Hospital, Belfast and is carried out by our specialist weight loss consultants.

Please be aware that Gastric sleeve surgery can be canceled if the patient gains any weight from the time they enter the programme and/or fails to comply with the liver reduction diet. 

Surgery can also be canceled if there are any unexpected findings at laparoscopy or if the liver is too large.
