Double Guidewire Technique Versus Transpancreatic Precut in Patients With Repetitive Unintentional Cannulation of the Pancreatic Duct.

Difficult cannulation of the common bile duct is encountered in about 10%of ERCP procedures. This frequently happens in the form of repeated unintentional cannulation of the pancreatic duct. Two valid options are available to facilitate cannulation at this point: Double guidewire technique or performing a transpancreatic precut. This is a randomized trial comparing the efficacy and Safety of double guidwire technique versus transpancreatic precut after three unintentional passages of the guidewire into the pancreatic duct.
