Core Tip

Core tip: The results suggest that a loop-tipped guidewire inserted in the pancreatic duct during stenting in patients who experience difficulties with selective biliary duct cannulation has the potential to assist with prevention of unintended insertion of the guidewire into side branches of the pancreatic duct, and thereby contribute to a reduced risk of post-endoscopic retrograde cholangiopancreatography pancreatitis or hyperamylasemia.
