Well: Robotic Surgery Report Card

There is bad news and worse news for robotic surgery in benign gynecologic procedures, a new study finds.

Robotic-assisted surgery accounted for 15 percent of oophorectomies, or removal of the ovaries, in 2012, up from 3.5 percent in 2009. The use of robots in cystectomies, the removal of ovarian cysts, rose to 12.9 percent of operations from 2.4 percent during the same period.

But in a study of more than 87,000 operations, researchers found the rate of complication during robotic surgeries for oophrectomy was 3.4 percent, compared with 2.1 percent for conventional surgery. There were complications during the procedure in 2.0 percent of robotic cystectomy operations, compared with 0.9 percent in regular operations.

Bladder and ureter damage accounted for most of the increased number of injuries in the robot-assisted operations.

The study, published online in Obstetrics & Gynecology, also found that robotic oophorectomy cost an average of $2,504 more than conventional surgery, and that a robotic cystectomy cost $3,310 more.

"There's no proven benefit to robotic surgery, and it's significantly more costly," said the lead author, Dr. Jason D. Wright, director of gynecological oncology at Columbia University Medical Center.
