• When the guidewire is placed into the biliary or pancreatic
duct with papilla observed in the left or right side of the
endoscopic image, the guidewire may move outside the view
of the endoscopic image because the forceps elevator is
raised extensively. In this case, do not operate the bending
section or insert or withdraw the insertion section forcibly or
abruptly. Patient injury, bleeding, and/or perforation may
result. If the guidewire moves outside the view of the
endoscopic image, perform treatment carefully while
observing the X-ray image, or lower the forceps elevator and
locate the papilla as centrally as possible in the endoscopic
image by adjusting the position of the distal end of
endoscope, and then raise the forceps elevator again.
