Sleeve gastrectomy is a primary surgery to lose weight. It is just like gastric banding but without the band. It involves cutting and stapling your stomach into a tube-like structure.
It provides the restrictive effect just like the band but it is not adjustable. The divided stomach (70% of your stomach) is removed. It is also done through key-hole surgery.
You will be in the hospital for 2 to 3 days after surgery. The complications are about the same as gastric banding plus risks of leakage from the staple line. The risk of dying from the operation is also very low, probably in the same range as in gastric banding.
One of the major advantages of this surgery compared to gastric banding is there is no adjustment needed. It probably suits persons with difficulty to follow-up with their doctors. The weight loss is automatic, but it also means you have no control over how the weight loss going to be like in a few years time.
The initial results were very promising with 50 to 60% of excess weight loss, i.e. 25 to 30kg for those who are 50kg overweight in one year. We expect the weight loss to level off after 2 to 3 years because the stomach will expand to a certain degree with mild regain of weight.
If target weight loss is not achieved, the second operation is possible to further the weight loss by converting this to another operation, such as gastric bypass or biliopancreatic diversion. That being said, most patients were happy with the results of this operation! Patients are normally follow-up every 3 months in the first 2 years.
