Sleeve Gastrectomy
Sleeve gastrectomy is a widely applied food intake restriction procedure in obesity surgical operations. In patients with gastric tube surgery, the food absorption is not a problem. So they don't need routine vitamin and mineral supplements.
For many patients, this procedure will be adequate but for super-obese patients, before malabsorptive operations, can be applied as primary surgery for to reduce the complications of surgery. This is an important treatment option for the patients with body mass index over 40.
During surgery, larger side of the stomach is cut off vertically with laparoscopic method to create a new, tube shaped stomach with 150-200 cc volume. Reducing the stomach volume leads to restriction of food intake and removing fundus part, which is secreting ghrelin hormone (known as hunger hormone), leads a feeling of fullness and contribute to weight loss.
Possible complications of surgery, which is also valid for all surgical procedures, are hemorrhage, organ injury, embolism and anesthesia-related complications. Special complication for this surgery is leakage from stitch line of the stomach. Sometimes you may need a second surgery or non-surgical interventions. The risk of death from surgery is a very low rate like 0.2% .
First 1-2 years after sleeve gastrectomy surgery, up to 60-70% of excess weight is lost. Results were similar to gastric bypass in many studies. Effect in patients who feed liquid and high calorie can be reduced because of this food intake restriction method. In the long term, re-gaining weight rate is 20% and being morbidly obese rate is 2%. In such cases, gastric bypass or duodenal switch procedures can be done.
