The user facility reported that the single use guidewire was used in combination with a duodenoscope (tjf-260v) from olympus for papillary dilation.After that, an attempt was made to place the guidewire and insert an olympus biliary endoscope (chf-b290) into the bile duct; however, the insertion was not smooth and the guidewire was forcibly preceded in a direction that could not be determined to be into the bile duct.Then, the biliary endoscope was advanced tracking the guidewire.As a result, the bile duct was perforated.It is unknown whether the bile duct was perforated by the guidewire or by the biliary endoscope.The final patient impact was non-serious.The procedure outcome was not reported.
