Laparoscopic, Bariatric and Thoracoscopic SurgeryWelcome to Our Blood Storage
Bariatric surgical procedures cause weight loss by restricting the amount of food the stomach can hold, causing malabsorption of nutrients, or by a combination of both gastric restriction and malabsorption. Bariatric procedures also often cause hormonal changes. Most weight loss surgeries today are performed using minimally invasive techniques (laparoscopic surgery). Surgical procedures are performed on patients suffering from obesity where weight loss is achieved through removal of a portion of the stomach or by resecting and re-routing the small intestine to a small stomach pouch. Additionally, operations performed in the abdomen and pelvic area using small incisions with the aid of a camera. The laparoscope aids diagnosis or therapeutic interventions with a few small cuts in the abdomen. The operation is usually performed laparoscopically by making five to six small incisions in the abdomen through which a small scope connected to a video camera and surgical tools are inserted. The surgeon staples the top portion of the stomach so it is separated from the bottom to create a small stomach pouch. This small pouch restricts food intake. A section of the small intestine called the jejunum is then attached to the small stomach pouch permitting food to bypass the lower stomach, the duodenum. This bypass reduces the number of calories and nutrients the body absorbs, called malabsorption.
- Produces significant long-term weight loss.
- Restricts the amount of food that can be consumed.
- May lead to conditions that increase energy expenditure.
- Produces favourable changes in gut hormones that reduce appetite and enhance satiety.
- Typical maintenance of >50% excess weight loss.
