Age at presentation of common pediatric surgical conditions: Reexamining dogma.
[hirschsprung disease]
The
commonly
cited
ages
at
presentation
of
many
pediatric
conditions
have
been
based
largely
on
single
center
or
outdated
epidemiologic
evidence
.
Thus
,
we
sought
to
examine
the
ages
at
presentation
of
common
pediatric
surgical
conditions
using
cases
from
large
national
databases
.
A
retrospective
analysis
was
performed
on
Healthcare
Cost
and
Utilization
Project
databases
from
1988
to
2009
.
Pediatric
discharges
were
selected
using
matched
ICD
9
diagnosis
and
procedure
codes
for
malrotation
,
intussusception
,
hypertrophic
pyloric
stenosis
(
HPS
)
,
incarcerated
inguinal
hernia
(
IH
)
,
and
Hirschsprung
disease
(
HD
)
.
Descriptive
statistics
were
computed
.
A
total
of
63
,
750
discharges
were
identified
,
comprising
2744
cases
of
malrotation
,
5831
of
intussusception
,
36
,
499
of
HPS
,
8564
of
IH
,
and
10
,
112
of
HD
.
About
58
.
2
%
of
malrotation
cases
presented
before
age
1
.
Moreover
,
92
.
8
%
of
HPS
presented
between
3
and
10
weeks
.
For
intussusception
,
50
.
3
%
and
91
.
4
%
presented
prior
to
ages
1
and
4
years
,
respectively
.
Also
,
55
.
8
%
of
IHD
cases
presented
before
their
first
birthday
.
For
HD
,
6
.
5
%
of
cases
presented
within
the
neonatal
period
and
45
.
9
%
prior
to
age
1
year
.
Our
findings
support
generally
cited
presenting
ages
for
HPS
and
intussusception
.
However
,
the
ages
at
presentation
for
HD
,
malrotation
,
and
IH
differ
from
commonly
cited
texts
.
