[Clinical value of thoracoscopic extensive mediastinal lymphadenectomy in the surgical treatment of esophageal carcinoma].
[esophageal carcinoma]
To
explore
the
safety
and
feasibility
of
extensive
mediastinal
lymphadenectomy
during
thoracoscopic
esophagectomy
in
the
treatment
of
esophageal
carcinoma
.
Clinical
data
of
125
patients
with
esophageal
carcinoma
undergoing
thoracoscopic
and
laparoscopic
esophagectomy
(
TLE
)
in
West
China
Hospital
of
Sichuan
University
between
May
2009
and
December
2011
were
retrospectively
analyzed
.
Patients
were
divided
into
2
groups
:
non-extensive
mediastinal
lymphadenectomy
group
(
non-extensive
group
,
n
=
53
)
and
extensive
mediastinal
lymphadenectomy
group
(
extensive
group
,
n
=
72
)
.
Perioperative
outcomes
of
these
two
groups
were
compared
.
No
significant
differences
were
found
in
the
time
of
thoracic
operation
,
length
of
intensive
care
unit
stay
and
postoperative
hospital
stay
,
postoperative
complication
and
the
overall
mortality
between
the
two
groups
.
Compared
with
non-extensive
group
,
extensive
group
showed
less
blood
loss
during
thoracic
operation

Seventeen
patients
(

.
6
%
)
in
extensive
group
were
found
to
have
positive
recurrent
laryngeal
nerve
lymph
nodes
,
which
resulted
in
upstaging
of
TNM
in
7
patients
(
9
.
7
%
)
.
The
incidence
of
recurrent
laryngeal
nerve
palsy
was
higher
in
extensive
group
as
compared
to
non-extensive
group
,
but
the
difference
was
not
statistically
significant

.
Extensive
mediastinal
lymphadenectomy
during
thoracoscopic
esophagectomy
is
a
feasible
and
safe
procedure
for
esophageal
carcinoma
patients
,
which
can
increase
the
number
of
harvested
lymph
node
and
the
accuracy
of
tumor
staging
.
