Gastric bypass - laparoscopic or robotic

Memorial Hospital Group

Gastric bypass surgery is an older operation method in comparison to other bariatric surgery methods. Therefore, it may be deemed as the most used bariatric surgery among others. In the first step of gastric bypass surgery, the stomach is reduced to 30 millilitres. The gastric tissue close to oesophagus and stomach junction is used. The stomach is connected to small intestine. There are two types of gastric bypass surgery. In the first type, the small intestine is formed in a thin circle and is connected to stomach. This is called as “Mini-gastric bypass”. In the second type of gastric bypass surgery, the small intestine is bypassed and one end is connected to stomach, while the other end is connected to small intestine. This method is known as “Roux en Y gastric bypass”. Except of small technical differences, the two methods have similar surgical results. The mechanism in gastric bypass surgery is restrictive as in gastric sleeve surgery, i.e. patient may intake limited amount of food and bile salts and pancreas enzymes found in duodenum meet the nutrients in a distal part of small intestine. Therefore, the breakdown and absorption of nutrients are rendered difficult and the absorption mechanism is changed. In other words, patient eats less and gets less benefits from nutrients. The change in gastrointestinal hormones is more significant than in gastric sleeve surgery. Patient feels less hungry, even though eating less and blood glucose is regulated. Losing 60-80% of body weight is one of its advantages. The gastric bypass surgery is a food intake restrictive method and it has a more significant effect on gastrointestinal hormones. Also it is a reversible procedure in comparison with gastric sleeve surgery.

Gastric sleeve surgery - robotic or laparoscopic

Gastric sleeve surgery is a bariatric operation, during which approximately 80% of stomach is removed. The weight loss is achieved with more than one mechanisms. First of all, the significantly reduced stomach volume leads to less food intake, and therefore, less calories.  However, the main effect is not restricting the food intake, but the change it creates on hormones regulating the hunger, fullness and blood glucose.

Personalize your knee replacement!

More than 600,000 knee-replacement surgeries are done in the United States every year, and as Baby Boomers continue to age, some say that figure will grow to 1 million within the next decade. Patients are increasingly choosing an option that allows doctors to build their patient’s knees.

Less than a year ago, climbing a flight of stairs would have been impossible for Amanda Fair-Evans. “I couldn’t even get out of the car, and I was like, ‘What is this?’” Fair-Evans said. The pain in her left knee was unbearable. Fair-Evans tried medication and cortisone shots and finally begged her doctor for surgery. “I have no quality of life,” Fair-Evans recalled saying. “I have grandkids and I want to play with my grandkids. Please give me a new knee.”

Dr. Mathew Pombo, an orthopedic surgeon, felt Fair-Evans would be a great candidate for a personalized replacement knee. A standing CT scan of a patient’s leg captures the alignment, followed by a three-dimensional printing process. “We can input components into the computer and print off a specific femur and a specific tibia that fits the bone perfectly,” Pombo said. It takes about six weeks for a medical company to create the custom knee. During surgery, doctors remove the damaged joint. Then, using individually designed tools, surgeons insert the new joint and cement it in. “It’s basically like putting a train on perfectly aligned train tracks,” Pombo said. “It should wear better.”

Five months later, Fair-Evans had her other knee replaced. Now she’s back to the things she loves to do. “(I’m) taking long walks, playing with my grandkids and dancing,” Fair-Evans said. “I haven’t danced in a long time.” Pombo said there is a faster recovery, less blood loss and easier range of motion when patients have the personalized 3D knee surgery.
