However
,
while
Paull
et

____________________
clarified
the
nature
of
the
histologic
lesion
,
the
____________________
definition
of
Barrett
esophagus
has
continued
to
change
.
____________________
people
believed
that
the
distal
esophagus
could
contain
a
____________________
region
of
columnar
mucosa
.
In
addition
,
determining
the
____________________
location
of
the
esophagogastric
junction
(
EGJ
)
____________________
patients
with
Barrett
esophagus
often
is
difficult
.
To
____________________
false
-
positive
diagnoses
,
investigators
selected
arbitrary
lengths
of
____________________
-
____________________
esophagus
to
establish
a
diagnosis
for
their
studies
.
____________________
,
community
endoscopists
embraced
this
practice
,
and
biopsy
of
the
____________________
-
____________________
normal
distal
columnar
-
lined
esophagus
was
avoided
.
Convincing
evidence
____________________
that
SIM
,
the
hallmark
histologic
lesion
of
Barrett
____________________
,
predisposes
to
dysplasia
and
cancer
regardless
of
the
____________________
location
.
Thus
,
the
definition
of
Barrett
esophagus
currently
____________________
the
