Assessment

Primary outcomes

Success rate of each angled type and straight type guidewire passing perihilar biliary stricture within 5 minutes.

Key secondary outcomes

1) Benign or malignancy of the underlying disease
2) Methiods of selective bile duct canulation
3) Required time for selective bile duct canulation
4) Required time for passing the stricture
5) Required number of guidewires for achieving requested bile duct canulation
6) Adverse event
7) Stricture length and type (Bismuth classification)
8) Total procedure time
9) All of performed procedures
10) Catheters and guidewires used in cases of failure (types, numbers).
