Why is there less blood loss with robot-assisted surgery?

Robot-assisted surgery using the da Vinci system is minimally invasive. It operates through a few small incisions, and tissue damage is minimal. Small incisions mean considerably reduced blood loss compared to the large incision method used in open surgery.

There are also other reasons for less blood loss in robot-assisted surgery:

  • the surgeon has better visibility on blood vessels than in open surgery or even laparoscopic surgery due to the high-definition cameras and the magnified 3D view: due to the high quality of visualization and the precision of the robotic arms movements, the surgeon is in increased control and more able to avoid injuries and damage to the blood vessels
  • a better view of the surgical field is also provided by the inflation of the abdomen with gas (usually, they use carbon dioxide): the gas pressure compresses the blood vessels, which is another cause for a decrease in blood loss
  • enhanced flexibility, clarity, and accuracy ensure the success of a complex procedure that otherwise might have been impossible through other techniques

Less blood loss in robotic surgery helps you avoid infections and further complications, lowers the need for blood transfusion to almost 0%, and provides a faster recovery process.
