First-of-its-kind
pediatric robotic surgery a success
By KRISTA CONGER
Two-month-old Daniel Pham doesn’t know it
yet, but he recently made history. Of course, like any techno-savvy
kid these days, he had a little help – namely in the form of
a 6-foot-tall, three-armed surgical robot known as “da
Vinci” and two highly skilled pediatric surgeons.
On Jan. 9, Craig Albanese, MD, and Thomas Krummel, MD, used the
robot to reconstruct a faulty connection between Daniel’s
liver and small intestine that, if left untreated, would have
required a liver transplant. Although da Vinci had lent an arm or
three in one other pediatric surgery since its arrival at the
medical center last fall, Daniel’s operation marked the first
time in the world that the robot had been used to perform the
technique, called the Kasai procedure.

center. The robot, called da Vinci, enabled surgeons to be more
precise while increasing their surgical range of motion.

“We’re changing the culture of surgery,” said
Albanese, chief of pediatric surgery. “Usually we have our
hands in there, feeling and doing. Even with the more recent
laparoscopic techniques we were still right at the patient’s
bedside. Now we’re taking several steps away to sit at a
remote console.”
The console, which looks somewhat like an overgrown version of a
child’s Viewmaster toy but sporting hand grips and foot
pedals, sits against the wall of the operating room about 10 feet
from the patient.
During Daniel’s surgery, Albanese manipulated the surgical
instruments from the console while Packard Children’s
Hospital surgeon-in-chief Krummel assisted at the bedside. Both
physicians are also professors of surgery at the School of
Medicine.
Daniel’s brush with fame was caused by a congenital
abnormality called biliary atresia. About 300 infants each year in
this country are born with the condition, which results in
destruction of the duct that delivers bile from the liver to the
small intestine. The accumulation of bile in the liver leads to
severe jaundice within roughly three weeks of birth, followed by
irreversible organ damage and death.
Like the more traditional manual surgery, Daniel’s procedure
was performed using minimally invasive techniques that required
only five small incisions in his abdomen. Although minimizing pain
and allowing for a faster recovery, such small entry points lead to
unavoidable technical problems. For instance, surgery must be
viewed in two dimensions on a monitor above the patient; the
surgeon can’t control the surgical instruments and the camera
simultaneously; and the instruments’ range of motion is
hampered by the anatomical restrictions of the human arm, wrist and
hand.
In contrast, the da Vinci, which is manufactured by Intuitive
Surgical Inc., treats the surgeon to a 3-D view of the ongoing
procedure. It gives total control of two instruments and a camera
via a console; hand and foot movements are translated into steady,
precise and unrestricted movement of the robot’s arms, which
hold surgical instruments that have been scaled down for use in
children. Other members of the team view the action on a monitor
perched next to the operating table.
As the president of the International Pediatric Endosurgery Group,
Albanese is no stranger to minimal-access surgery. His years of
experience help him appreciate another, equally important benefit
of robotic surgery.
“It’s incredibly comfortable,” said Albanese.
“Surgery can be tiresome and ergonomically uncomfortable.
With the robot, I can place my head in a comfortable viewing box
and rest my arms on a cushioned armrest. Then I go about moving my
hands and arms just like I would in a traditional surgery.” A
microphone connected to a speaker near the bedside monitor
amplifies the surgeon’s voice for the rest of the surgical
team, instructing them when to swap instruments, commenting on the
procedure or conferring with the surgeon at the bedside.
The robot’s lack of some human characteristics also can be an
advantage.
“The robot filters out any hand tremor and scales
motion,” said Albanese. “I can move my hands five
centimeters and the instrument moves only one. This allows more
sweeping motions and increases the comfort and precision of the
surgery. ”
As for this particular procedure, “The surgery went really
nicely,” said Albanese. “Daniel’s doing very
well.”
All this might not matter much to Daniel now, but he – and
the many other children at Lucile Packard Children’s Hospital
that will likely experience the robot’s ministrations in the
coming years – will appreciate it later.
