A DaVinci robot may be able to help bypass surgery patients stay for a shorter duration in the hospital as well as experience fewer complications because it is minimally invasive, researchers at the University of Maryland have found.

They also found that robotic heart bypass surgery makes good economic sense for hospitals.

Robert S. Poston, M.D., a cardiac surgeon formerly at the University of Maryland Medical Center, who is the lead author of the study, said that using a surgical robot increases the cost of each bypass case by about 8,000 dollars.

He found that the robotic approach saves costs especially with high-risk patients who have lung or kidney disease or other health problems.

"Our study shows that there are health benefits to patients from the minimally invasive approach, both in terms of a shorter recovery and also looking at the function of the bypass graft months after the surgery," Stephen T. Bartlett, M.D., who is one of the study's co-authors.

For the study, the researchers examined 100 consecutive patients who had minimally invasive coronary bypass surgery using the robot. The technique requires no incisions except for a few small holes to insert instruments.

These cases were compared to a matched group of 100 patients who had the traditional open bypass surgery with a sternotomy, a surgical incision through the sternum.

Researchers found that the average time-span of the hospital stay for the patients with the minimally invasive surgery was about four days while it was seven days for the traditional bypass operation.
