Endoscopic imaging in Barrett's esophagus.
[esophageal adenocarcinoma]
Barrett
's
esophagus
is
the
only
known
precursor
that
predisposes
patients
to
the
development
of
esophageal
adenocarcinoma
.
The
current
recommended
surveillance
method
is
targeted
biopsies
of
any
abnormalities
followed
by
random
four
-quadrant
biopsies
every
2
cm
using
standard
white
light
endoscopy
.
Compliance
with
this
and
sampling
error
are
two
of
the
biggest
problems
.
Several
novel
imaging
technologies
have
been
developed
to
aid
the
diagnosis
of
early
neoplasia
in
Barrett
's
esophagus
.
There
are
emerging
data
that
some
of
these
new
modalities
can
increase
the
yield
of
detecting
dysplasia
.
This
review
will
discuss
some
of
the
present
available
techniques
and
technologies
including
chromoendoscopy
,
narrow
-band
imaging
,
autofluorescence
imaging
,
optical
coherence
tomography
,
confocal
endomicroscopy
and
endocytoscopy
.
Based
on
the
current
evidence
,
these
imaging
modalities
appear
to
be
promising
as
adjunctive
tools
to
white
light
endoscopy
.
A
few
of
them
,
nevertheless
,
remain
experimental
due
to
expense
,
lack
of
expertise
,
generalizability
as
well
as
reproducibility
of
results
.
