What is gastric-band surgery? Lap-band surgery

Gastric-band surgery is designed to help people shed most of their excess body fat by helping them feel full all the time.

To achieve this feeling of fullness (satiety), an inflatable silicone band is fitted around the top of the stomach which creates a small pouch above the band. Placing the band in this way effectively reduces the size of the stomach to the size of a mandarin.

With a much smaller stomach, people who have had gastric-band surgery can't eat much more than a handful of food before they are completely full and lose all interest in eating. If they do eat more than their smaller stomach can handle, they experience stomach pain and may vomit the food up.

The advantages of gastric-band surgery Lap-band surgery

Gastric-band surgery is the latest surgical procedure to help morbidly obese people lose weight and has many benefits over its predecessors, small bowel bypass and stomach stapling. Lap band surgery
Specifically these advantages include:

• The tightness of the gastric-band can be adjusted.



• The gastric-band is placed using key-hole surgery which doesn't leave large scars and minimises post-surgery recovery time.



• Gastric-band surgery is reversible and because nothing permanent has been done to the stomach, it can return to its normal shape.

Who is considered suitable for Gastric-band surgery?

Gastric-band surgery isn't for everyone. In fact, it is considered a solution of last resort for very overweight people whose weight is dramatically impacting their quality of life or life expectancy.

Whether or not someone is considered appropriate for gastric-band surgery depends on a number of factors which the performing surgeon will consider before proceeding with the surgery.

These conditions usually relate to how overweight a person is, what other weight loss methods they've tried, how badly their weight is affecting their health, their age and their understanding of the risks and post-surgery responsibilities regarding healthier eating and exercise.

When it comes to how overweight a person is, a Body Mass Index of 35 or more is considered appropriate for gastric-band surgery.

As well as being morbidly obese, surgeons generally want to know that potential patients have exhausted all other methods of losing weight.

If a potential patient already has many of the diseases caused or made worse by being overweight, such as diabetes and high blood pressure, they are far more likely to be considered appropriate candidates for surgery.

In addition to the above, some surgeons may also take into consideration the age and future life-expectancy of potential patients. In most instances, surgeons generally won't operate on patients who are over 65 or who are under 14 years of age.

We'll get to the potential risks involved with gastric-band surgery in a moment, but to be considered for surgery a person also needs to be 100% committed to eating smaller portions of nutrient-rich foods and exercising for the rest of their lives after the operation.

What does gastric-band surgery involve? Lap-band surgery

Once the decision has been made by the patient and surgeon to go ahead with gastric-band surgery, a number of preliminary tests are conducted to assess the patient's current state of health and minimise any risks associated with the procedure.

The gastric-band surgery itself is performed under a general anaesthetic and takes about one hour to perform.

In addition to placing the gastric-band around the top of the stomach, the surgeon will also place an access port in the abdominal wall (just under the skin). It is via this access port that fluid is regulated to tighten or ease the restriction of the band.

After an overnight stay in hospital an X-ray of the stomach is performed to make sure everything is as it should be.

After leaving hospital, patients normally take a couple of weeks to start performing normal activities.  At this time, most gastric-band surgery patients still feel tired towards the end of the day and are still learning what eating habits suit them best.

During the first three weeks post-surgery, patients are placed on a liquid-only diet and tend to experience quite a bit of weight loss as a result.

The first phase of this liquid-only diet consists solely of clear fluids and once patients are comfortably coping with these, they are introduced to liquid foods and then very soft foods such as soups, yogurt and stewed fruit.

After a month or so, most patients are eating the foods that will make up their permanent diet.

Unless unforeseen circumstances arise or the gastric-band needs immediate adjustment, the only real ongoing medical support needed is annual check-ups with the operating surgeon.

How much does gastric-band surgery cost? Lap-band surgery

In 2006, gastric-band surgery costs around $10,000*.

Gastric-band surgery is available in the public health system at no cost, but waiting lists for the procedure are long.

For the privately insured, out of pocket expenses are around $3,000 but the surgery can be performed almost immediately.

Gastric-band surgery success rates Lap-band surgery

Gastric-band surgery is reported to have success rates of around 90%.

On average, people who have gastric-band surgery can expect to lose between one half and two-thirds of their excess weight.

For example, a person weighing 100 kilograms and an ideal weight of 60 kilograms has excess weight of around 40 kilograms. One half to two-thirds of this excess weight equals 20 to 26 kilograms. Therefore this person could typically expect that their weight would come down to around 74 to 80 kilograms if they had gastric-band surgery.

Older patients and those addicted to liquid calories such as colas, milkshakes and fruit juices as well as calorie dense foods like chocolate, typically struggle to achieve this kind of result.

The risks associated with gastric-band surgery

Some of the risks associated with gastric-band surgery are typical of any medical procedure while others relate to the placement of the gastric-band itself.

General medical procedure risks include things like surgical complications, infection, tissue and organ damage, heart attack and blood clots.

In addition to these very serious risks, gastric-band surgery patients are also at risk of experiencing less serious by ongoing conditions such as heartburn, reflux and vomiting.

Limitations of gastric-band surgery Lap-band surgery

Gastric-band surgery only facilitates weight loss.

What actually causes the weight loss is the practice of healthy new lifestyle habits that patients must commit to for life post-surgery.

Not surprisingly, these new lifestyle habits involve healthier eating and regular exercise.

Because so little food can be eaten at one time once the gastric-band is fitted, the healthier eating guidelines need to be particularly strict and restrictive.

Because patients can only eat a small amount each day, the food they consume must be very nutritious.

Ideal food choices include foods that are low in fat, low in simple sugars, high in protein and high in fibre. Ideally, these foods are consumed in three small meals per day with no eating in between meals.

Junk food and foods high in calories such as potato chips, biscuits, cakes and chocolate are to be completely avoided.

Because the gastric-band only works with solid food, the consumption of liquids needs to be monitored closely and liquids that contain calories, such as colas, fruit juices, alcohol and milkshakes are for the most part a 'no-no'.

In addition to following these general healthy eating guidelines, many gastric-band surgery patients find that there are some foods that their body will no longer tolerate post-surgery. These foods vary between patients but typically include things like bread and pastas.

In addition to eating healthily, gastric-band surgery patients are advised to exercise for at least 30 minutes per day in order to maximise their weight loss.
