Bariatric Surgery

Learn about bariatric surgery and understand your options

Aim for a lasting change

Your weight could be holding you back from enjoying life to the fullest. Obesity can take a physical and emotional toll that may be truly worrying to you and your family. When left untreated, obesity can lead to heart disease, type II diabetes, and other chronic diseases.1 If dieting, exercise, and medicine alone haven’t worked for you, it may be time to consider an additional option.

If you’re considering surgery, you may be surprised to learn that more than 1.3 million people underwent bariatric surgery to lose weight from 2011 through 2017.2 

According to a study of 164,247 patients, one year after surgery patients who underwent a sleeve gastrectomy lost an average of 29.5 percent of their total body weight, while those who had Roux-en-Y gastric bypass lost an average of 34.2 percent.3 Sleeve gastrectomy and Roux-en-Y gastric bypass are two of the most common bariatric surgeries.4

Surgery alone is not enough. You must follow the recommended changes from your healthcare team after surgery for you to make a lasting change.

Understanding your options

There are many ways to lose weight that you can explore with your doctor, such as changing your diet, exercising, medication, and surgery. If you’re considering surgery, your surgeon should discuss your options with you. 

Sleeve gastrectomy reduces your stomach size by about 80 percent to limit the amount of food it can hold. You may lose weight because you can only eat small amounts of food.4 Roux-en-Y gastric bypass reduces your stomach size while also rerouting your small intestine to decrease the amount of nutrients your body absorbs. You may lose weight by eating less and absorbing fewer nutrients.4 Both procedures may cause favorable changes in your gut hormones to reduce appetite and improve feeling full.4

Both sleeve gastrectomy and gastric bypass surgeries are almost always performed using minimally invasive techniques—either laparoscopic surgery or robotic-assisted surgery, possibly with da Vinci® technology.5 Surgeons perform minimally invasive laparoscopic or robotic-assisted surgeries through a few small incisions. To perform a laparoscopic bariatric surgery, surgeons use special long-handled tools while viewing magnified images from the laparoscope (camera) on a video screen.

How da Vinci works

Surgeons can perform both sleeve gastrectomy and Roux-en-Y gastric bypass surgeries using robotic-assisted surgery with da Vinci technology. With da Vinci, your surgeon sits at a console next to you and operates using tiny instruments through a few small incisions.

A camera provides a high-definition, 3D magnified view inside your body. Every hand movement your surgeon makes is translated by the da Vinci System in real-time to bend and rotate the instruments with precision.

It’s important to remember that Intuitive does not provide medical advice. After discussing all options with your doctor, only you and your doctor can determine whether surgery with da Vinci is appropriate for your situation. You should always ask your surgeon about his or her training, experience, and patient outcomes.

More about da Vinci

Why surgery with da Vinci?

A review of published studies suggests potential benefits of gastric bypass surgery when using da Vinci technology include:

  • Patients experience complications after surgery at a similar, though sometimes lower, rate as patients who had a laparoscopic procedure.6-15
  • Patients experience complications during surgery at a similar rate as patients who had a laparoscopic procedure.6-8,11,13,14
  • There is a similar, though sometimes shorter, length of stay in hospital compared to laparoscopic surgery.5,6,9-15

All surgery involves risk. You can read more about associated risks of bariatric surgery here.

Questions you can ask your doctor

  • What types of weight-loss surgery are available and which is best for me?
  • What is the difference between laparoscopic and robotic-assisted surgery?
  • Can you tell me about your training, experience, and patient outcomes with da Vinci?
  • How will I feel after surgery?
  • What changes should I make after surgery?

More about general surgery with da Vinci

Robotic-assisted surgery with da Vinci technology is used in many different types of procedures by general surgeons.
