Bariatric surgery may be suggested to patients with a high Body Mass Index (BMI) and other medical conditions related to obesity.

Bariatric surgery can be done using open surgery through a large incision (cut). It can also be done using minimally invasive surgery – through a few small incisions – with traditional laparoscopy or da Vinci Surgery (da VinciGastric Bypass or da Vinci Gastric Sleeve Surgery).

Gastric Bypass

Gastric bypass shrinks your stomach size and reroutes your digestive tract. During surgery, doctors divide your stomach to create a new, smaller stomach. The new stomach is attached to the small intestine and bypasses the larger part of your original stomach. Your new stomach is now much smaller — as is the amount of food it can hold.

Gastric Sleeve

During gastric sleeve surgery, also known as sleeve gastrectomy, most of your stomach is removed. As with gastric bypass, the smaller, sleeve-shaped stomach that remains is sealed and holds smaller amounts of food.

Why da Vinci Surgery?

The da Vinci System is a robotic-assisted surgical device that your surgeon is 100% in control of at all times. The da Vinci System gives surgeons:

  • A 3D HD view inside your body
  • Wristed instruments that bend and rotate far greater than the human hand
  • Enhanced vision, precision and control

da Vinci Gastric Bypass Surgery offers the following potential benefits:

  • Low rate of gastrointestinal leaks 1,2
  • Short hospital stay 1,3,4
  • Low risk of needing follow-up surgery 2,5

da Vinci Gastric Bypass Surgery offers the following potential benefits similar to traditional laparoscopy:

  • Low risk of surgeon switching to open surgery 2,4,6


The da Vinci System has brought minimally invasive surgery to more than 3 million patients worldwide. da Vinci technology– changing the experience of surgery for people around the world.


Risks & Considerations Related to Bariatric Surgery (includesgastric bypass (stomach reduction surgery), sleeve gastrectomy and duodenal switch): leaking and/or narrowing at the spot where two parts of the bowel were reconnected, leaking from where the bowel is cut, malnutrition, dumping syndrome (food moves too quickly into small intestine), dehydration, need for supplementation of vitamins, minerals and protein.

Contraindications to endoscopic surgery include morbid obesity.
