Summary

Selective cannulation is considered the most challenging step for most of Endoscopic retrograde cholangiopancreatography (ERCP). Wire-guided cannulation is the standard technique for initial cannulation. When meeting difficulty, double wire technique (DWT) is widely used. With one guidewire occupying pancreatic duct (PD), the following cannulation of common bile duct (CBD) with a sphincterotome preloaded with another guidewire often becomes feasible. However, because of the small opening of the papilla, sometimes it is technically challenging for the following cannulation of CBD with the sphincterotome and PD guidewire in the same working channel. We hypothesized that a tiny cut of the opening of papilla, without the injury of pancreatic sphincter, may facilitate the success of DWT and shorten the overall cannulation time.

Conditions

  • Biliary Cannulation
  • Endoscopic Retrograde Cholangiopancreatography

Interventions

PROCEDURE

Modified double wire technique

For experimental arm, a tiny cut of papilla orifice, with the length of 5mm, was performed by sphincterotome before the double wire cannulation.
