Lately there has been a lot of hype concerning
Laser and Robotic surgery. But what is it and is it really better? Most
of the time it is not.
Robotic surgery is not R2D2 doing surgery. It is more like a remote control
hobby device; the surgeon is working from a remote control device while
the machine follows his instructions. He (or she) is usually watching
on a TV screen; but sometimes live. Recent advances may involve a 3D
virtual reality; allowing remote operations by tele-medicine.
The advantages of robotics include a finer control of movement with less
slipping of the knife likely. As well, surgery is possible in very
confined locations. Disadvantages include the lack of direct
visualization and two-dimensional pictures. A major issue is the lack of
sensory feedback; most robotics do not allow that. The surgeon does not
know when the tissue has a different feel or density.
So for
most surgeries an experienced surgeon doing it manually is far better
than robotics. Indeed in a recent study of benign ovarian lesions on
87,000 women researchers found there were 50% more complications in
robotic cases.
Lasers are being used in surgery as special
knives or scalpels. They burn a very fine line through tissue, and have
minimal bleeding due to the cauterization. However, like robotics, there
is no feedback from the tissue; and there effects of small surgical
errors by the operator are magnified.
There are several tissue
specific colored lasers but these also can damage normal tissue. I had
three cases of patients who had green laser prostate surgery by an
inexperienced laser surgeon. All three had severe complications and
required additional surgeries and long term incontinence.
Much
of the hype about laser and robotic surgeries has been promulgated by
the manufacturers of this very expensive equipment whose surgeries are
far more expensive than standard procedures. Like new drugs we need to
be cautious; they are rarely major advances.
I review a
surgeon's experience and complication rates. I much prefer an
experienced surgeon using standard instruments. Never be afraid of
asking how many of these procedures the surgeon has performed; if the
physician gets insulted I would strongly recommend you go somewhere
else.
