The procedure
The sleeve gastrectomy was initially used as the first in a two-stage weight loss procedure for the super morbidly obese. However it has gained popularity as a stand alone operation and is now the most commonly performed weight loss procedure in Australia.
It involves removing approximately two-thirds of the stomach. This is done via a laparoscopic (key-hole) technique. A plastic tube, known as a Bougie, is placed down the gullet and into the stomach to calibrate the amount of stomach remaining. Once in place, a surgical stapling device is used to create the new stomach tube. The excess stomach is then removed from the abdomen.
Quick info
- Operating time of approx. 45 to 75 mins
- Average hospital stay of 2 days
- Average time off work from 2 to 4 weeks
- Procedure is not reversible
- Weight loss surgery financing plans available
How it works
It would seem that removing a large proportion of the stomach, and in turn reducing oral intake, would be the main reason for weight loss in the sleeve gastrectomy. However there are more complex mechanisms related to gut hormones and signalling that comes from removing that specific portion of stomach. This leads to changes in glucose (or sugar) metabolism, satiety (fullness) and hunger.
Advantages
- With proper aftercare, can have long lasting weight reduction
- Technically easier procedure
- Less malabsorptive issues than with a bypass
- Less micronutrient deficiencies than with a bypass
Disadvantages
- Can increase reflux, if present. This will be something that your surgeon will discuss with you
- Risk of a leak from the staple line
