Endoscopic ultrasound-guided biliary drainage for right hepatic bile duct obstruction: novel technical tips.
[cholangiocarcinoma]
Endoscopic
ultrasound
(
EUS
)
-
guided
biliary
drainage
(
EUS-BD
)
is
not
normally
indicated
for
an
obstructed
right
intrahepatic
bile
duct
(
IHBD
)
.
The
technical
feasibility
and
clinical
efficacy
of
a
novel
technique
of
EUS-BD
for
right
IHBD
obstruction
were
evaluated
.
A
total
of
11
patients
underwent
drainage
using
either
a
left
or
a
right
biliary
access
route
.
The
causes
of
obstructive
jaundice
were
cholangiocarcinoma
(
n
 
=
 
6
)
,
pancreatic
cancer
(
n
 
=
 
3
)
,
gastric
cancer
(
n
 
=
 
1
)
,
and
colon
cancer
(
n
 
=
 
1
)
.
After
placement
of
an
uncovered
metal
stent
to
bridge
the
obstruction
,
a
hepaticogastrostomy
was
completed
using
a
covered
stent
.
Mean
procedure
time
was
33
.
9
 
±
 
10
.
0
minutes
.
Technical
and
functional
success
were
achieved
in
all
patients
,
and
no
adverse
events
occurred
.
This
novel
method
appears
to
be
safe
and
effective
for
right
IHBD
obstruction
.
