Intro to Operations

Over the last four decades as the obesity rate has skyrocketed dozens of studies have demonstrated that only 5% of morbidly obese individuals can lose weight and keep it off with diet and exercise. On the other hand about 70% of people who undergo bariatric surgery with long-term follow-up can lose the weight and keep it off. Obesity is a very misunderstood disease and unfortunately many obese individuals are made to feel that they are failures and that they have no self discipline. This mindset shows how poorly obesity is understood in society in general and even within the medical community. At Idaho BMI we recognize the underlying causes of obesity and we are always pursuing an understanding of how bariatric surgery really works. This gives us an advantage in developing tools that make our comprehensive approach successful for our patients. There are two bariatric operations we perform at Idaho BMI, the Sleeve Gastrectomy and Roux en Y Gastric Bypass. Both procedures are done laparoscopically meaning we access the abdominal cavity through very small incisions using a camera. Let’s review the basics of these operations. The laparoscopic sleeve gastrectomy takes about 30 minutes to perform. The concept with this operation is quite simple. We use a stapling device to staple along the stomach and remove 70 to 80% of the stomach. When we are done a person’s stomach is in the shape of a tube or shirt sleeve which is where it gets the name. This does many things. It causes a person to feel full and satisfied much more quickly and easily when they eat. It also lowers the level of a hormone called Ghrelin that causes hunger pains. After this operation people do not feel hungry very often or very intensely. This operation does not cause malabsorption. The Laparoscopic Roux-en-Y gastric bypass usually takes an hour and a half to two hours in the operating room. This operation is a little more complicated. In the first part of the operation the upper portion of the stomach is detached from the rest of the stomach. This upper part of the stomach is called the gastric pouch or stomach pouch. It will hold about an eggs worth of food. In the second part of the operation a stapler is used to divide the small intestine. The lower part of the small intestine is then brought up and attached to the stomach pouch that was created earlier. The upper part of the small intestine is attached to what used to be the downstream part of the small intestine. This operation also does many things due to the small size of the gastric pouch. It causes a person to feel full and satisfied very quickly when they eat. It also causes malabsorption meaning a person does not absorb all the food that they eat. Both operations change the levels of several hormones in a person’s body changing both metabolism and brain chemistry. In general, the gastric bypass is a higher risk operation compared to the sleeve gastrectomy. After either operation it is very important to adopt the focused lifestyle we teach. The lifestyle that makes these changes more permanent and makes long-term success more likely. The stay in the hospital after these operations is one night. At Idaho BMI we work very closely with you after the operation and walk you through the process of adopting this new way of living. It is a path that leads to freedom and help.
