Robot hot among surgeons but FDA taking a new look

(Continued)

But the Food and Drug Administration is looking into a spike in reported problems during robotic surgeries. Earlier this year, the FDA began a survey of surgeons using the robotic system. The agency conducts such surveys of devices routinely, but FDA spokeswoman Synim Rivers said the reason for it now "is the increase in number of reports received" about da Vinci.

Reports filed since early last year include at least five deaths.

Whether there truly are more problems recently is uncertain. Rivers said she couldn't quantify the increase and that it may simply reflect more awareness among doctors and hospitals about the need to report problems. Doctors aren't required to report such things; device makers and hospitals are.

It could also reflect wider use. Last year there were 367,000 robot surgeries versus 114,000 in 2008, according to da Vinci's maker, Intuitive Surgical Inc. of Sunnyvale, Calif.

Da Vinci is the company's only product, and it's the only robotic system cleared for soft-tissue surgery by the FDA. There are other robotic devices approved for neurosurgery and orthopedics, among other things.

A search for the company's name in an FDA database of reported problems related to medical devices brings up 500 reports since Jan. 1, 2012. Many of those came from Intuitive Surgical. The reports include incidents that happened several years ago and some are duplicates. There's also no proof any of the problems were caused by the robot, and many didn't injure patients. Reports filed this year include:

A woman who died during a 2012 hysterectomy when the surgeon-controlled robot accidentally nicked a blood vessel.

A Chicago man who died in 2007 after spleen surgery.

A New York man whose colon was allegedly perforated during prostate surgery. Da Vinci's maker filed that report after seeing a newspaper article about it and said the doctor's office declined to provide additional information.
