| EPT - guide wire directed |
 |
 |
|
An EPT is performed guide wire
directed regularly at our institution.
This ensures correct position of the papillotoma in the bile
duct.
The teflon covered terumo- guide wire is inserted by means of
"seldinger"
manoeuvre through a catheter into the bile duct (left figure).
After the catheter is removed, the papillotoma is inserted
over the guide
wire. The location of the guide wire is continuously
controlled by radiological imaging. The position of the papillotoma´s cutting
device (right
figure) is recommended to be vertical to the papilla´s roof (between
11:00
and 01.00 o´clock). The position shown here corresponds to
1:00 o´clock.
The guide wire can be left in the bile duct during the
procedure since it is
teflon covered.
