Gastric Sleeve Surgeons Perth

Sleeve gastrectomy is also known as gastric sleeve and is the most popular operation in the field of weight loss surgery.

This operation would be beneficial in the following situations:


Patients who live a long way from specialist follow up clinics and may encounter trouble attending regular reviews.


There are some situations where a sleeve procedure might be preferable to a gastric band operation (for example: when the function of the oesophagus is reduced).


Research into this area is emerging, helping clinics to aid patient decisions.

Following Unsuccessful Gastric Banding

Sleeve gastrectomy  offers patients an alternative to replacement of the band.

Patient preference

After discussions between the patient and their gastric sleeve surgeon, patients may decide that the sleeve gastrectomy procedure suits them better than other surgical options and this may be related to their food tolerances.

This operation is a permanent procedure and cannot be reversed.

How Much Weight Will I Lose?

The initial weight loss after a sleeve gastrectomy is very impressive and it is quite common for patients to lose up to 70% of their excess weight in the first 2 years. The new stomach does stretch over time and patients will find they are able to eat slightly more. This does tend to result in some weight re-gain. We find that the majority of our patients are able to maintain 60% of excess weight loss.

The Gastric Sleeve Operation

The surgery is performed under general anaesthesia, Laparoscopic (keyhole) surgery is used to remove most of the stomach, leaving a narrow tube with a capacity of 150 mL, ie. about half a cup.

A stapling device is used to seal the incision as it is being made during the procedure. The incision line is thoroughly inspected during and after the procedure.

Because the stomach is significantly smaller after surgery, the person feels full after a much smaller meal, but can usually eat a wide range of foods.

Weight-related co-morbidities such as diabetes, obstructive sleep apnoea and hypertension resolve along with successful weight loss.

Surgery Risks

The general risks of surgery, and of rapid weight loss apply to this operation just like the adjustable gastric band or gastric bypass.

Specific risks of the operation include:

Leakage from the gastric staple line in 1.0 %, Postoperative bleeding in 0.5 – 1% of cases, stricture (tight scar in the stomach tube) in 2%.

These risks are higher when the surgery is done in patients who have had previous gastric operations or have a BMI greater than 50.

Long term risks & side effects include:

Vomiting in 20%, gastro-oesophageal reflux in 30%, anaemia, vitamin D deficiency, inadequate weight loss or late weight re-gain can occur.

Other risks and side effects may include nausea, anorexia and revision surgery.

Post Operation Problems


This is due to the fact that you are probably not drinking as much liquid as you were able to before surgery; therefore, the volume in your body is reduced.

Altered bowel habits

Bowel habits may be altered after the surgery. In the beginning, you may have watery bowel movements.

Do not expect your bowel movements to be regular until you start eating solid food.


During the first two months after surgery, you may experience a few episodes of vomiting. It is important to remember your new stomach is approximately 150 mL (just over half a cup) and can be easily overwhelmed.

You must eat slowly and stop when you feel full.

Please make sure you follow your dietary advice carefully.
