What is Sleeve gastrectomy?
This is the most common weight loss surgery currently performed in Australia. The surgery is considered a restrictive procedure with 75-80% of the stomach along the greater curve, removed permanently.
This results in a reduction of volume and allows the patient to become full or reach satiety sooner. The additional benefit of removing this part of the stomach is the loss of the hormone ghrelin, which is thought to be the hormone that drives the hunger sensation. Furthermore there is some suggestion that small tube remnant of stomach encourages faster transit through the stomach and into the small bowel releasing hormones GLP1 and PYY3-36 which help with better blood sugar control.
All of these combine to result in increased weight loss & reduction in obesity related co-morbidities.
Do I need to change my diet after a sleeve gastrectomy?
Initially after the surgery you will be on a fluid diet. This can include soups, shakes or anything that can go down a straw. This will be for the first 2 weeks after the surgery. There will be a gradual increase to soft and full diet following this.
It is important to remember that this operation like other bariatric surgeries is not a substitute for poor eating habits. The weight loss surgery gives you and your body the ability to change your diet to a healthy one in a sustainable manner.
Do I need to change my diet before surgery?
Generally patients will need to be on a very low calorie diet for between 2-4 weeks depending on their BMI. This helps reduce the intra-abdominal fat and the fat content within the liver facilitating the surgery.
Why choose the laparoscopic sleeve gastrectomy?
It is important to see your specialist to discuss the preoperative management, postoperative management as well as the potential complications of the sleeve gastrectomy. The weight loss is rapid in the first 6-12 months. The compliance for a patient after a sleeve gastrectomy is generally better than after a gastric band insertion. The surgery itself is less complicated than the gastric bypass.
How long does the surgery take?
The surgery typically takes between 1- 2 hours. This sometimes can be complicated with the incidental presence of a hiatus hernia which is typically repaired during this time.
How long do I stay in hospital?
Most times your hospital stay varies between 1-3 days. This changes on an individual basis, depending on your medical risk factors, BMI and postoperative recovery.
How successful is laparoscopic sleeve gastrectomy in reducing my weight?
Patients will generally lose a significant portion of their excess body weight following the sleeve gastrectomy. Patients need to remember that this is not a substitute for poor food choices. In some instances patient can put some of the weight they lost back on in a couple of years if they indulge in poor food choices.
