New Study Shows Children
With Spina Bifida Fare Better With In Utero Surgery
Part Five of Five
By Dave Andrusko
I did not read, or read
about, a study published online Wednesday in the New England
Journal of Medicine until after I had been steered to a report
on "ABC News Tonight" that same evening (http://abcnews.go.com/Health/w_ParentingResource/spina-bifida-babies-face-outlook-surgery-womb/story?id=12877182).
Anchor Diane Sawyer
enthusiastically introduced a story about the study which proved
the benefits of correcting spina bifida while the baby is in his
or her mother's womb, rather than waiting until after birth. A
smiling Sawyer said,
"We have medical news
now. the result of a surgical experiment so promising, so
profound the limits were lifted on the experiment so everyone
could benefit.
It involves surgery in
the womb with tiny instruments, microscopic skill and dexterity
on a devastating birth defect that affects 1,500 newborns every
year. And Deborah Roberts reports on the news tonight that could
led to other life- changing surgery for babies before they are
born."
Like you, I was vaguely
aware that fetal surgery has been going on for a long time,
particularly in cases of spina bifida, but that there were
concerns that it might pose risks to unborn child and mother.
Spina bifida happens when
the spine of the baby fails to close during the first few months
of pregnancy. It can be associated with brain and nerve damage,
including paralysis. Typically, prompt surgery after birth can
prevent further harm but it cannot reverse the nerve damage that
has already taken place.
"By the end of 2002, more
than 230 spina bifida operations had been done, but some doctors
remained skeptical," is the way the Associated Press (AP)
described the situation. "So the National Institutes of Health
launched a big study that year at Vanderbilt, the Philadelphia
hospital and the University of California, San Francisco. Other
hospitals agreed not to do the surgery while the research was
under way."
Half of 158 babies had
surgery in utero (between 19 and 25 weeks) and half after
delivery, according to the study in the New England Journal of
Medicine.
"By the time they turned a
year old, 40 percent in the fetal surgery group needed a
drainage tube, or shunt, in the brain, compared with 82 percent
in the standard surgery group," according to the AP. "The fetal
surgery group scored higher on combined tests of mental
development and motor skills at 2½ years, though there was no
difference in cognitive function alone." In addition, "Forty-two
percent of the toddlers in the fetal surgery group could walk
without crutches or other support versus 21 percent in the other
group."
Furthermore, a year out
babies who'd had surgery before birth . They found that after
one year, those who had surgery before birth were less likely to
need follow-up surgeries than infants who had surgery after
birth--30 percent less likely.
Researchers also found
that 80% of babies who had fetal surgery were born prematurely
(as compared with 15% in the after-delivery group)--on average
about a month and a half early. "A third of the mothers who had
the operation had thinning in the wall of their uterus, a
complication that requires cesarean delivery in the future," the
AP reported.
Dr. Scott Adzick, chief of
surgery at Children's Hospital of Philadelphia, was first author
of the study. "This is a big breakthrough," he told ABC News'
Lara Salahi. "For the first time we can show a clear cut
benefit, treating a non life threatening malformation by
repairing it before birth."
One of the children
featured on the broadcast who had previously undergone in utero
surgery was Sean Mulligan. Now 10, Sean walks without the help
of crutches or a wheelchair.
"That's the gratifying
thing," said Adzick, who was Sean's surgeon."Not statistics and
all that sort of stuff, but seeing the impact of that operation
on that kid."
"I don't think it gets
better than that."
