Dye-free Wire-guided Cannulation of the Biliary Tree During ERCP is Associated With High Success and Low Complication Rates: Outcomes in a Single Operator Experience of 822 Cases

Deep biliary cannulation (DBC) is a prerequisite to most endoscopic retrograde cholangiopancreatographies (ERCPs). Numerous techniques have been described to maximize success and minimize ERCP-related complications, most notably post-ERCP pancreatitis. Dye-free cannulation by using guidewires with hydrophilic tips has been proposed as a technique with a high rate of success and a low rate of complications. We report the outcomes 822 consecutive ERCP procedures by using dye-free guidewire cannulation techniques. To evaluate the success rate for DBC and rates of complications by using dye-free guidewire cannulation techniques. Retrospective. Consecutive ERCP procedures with intent to achieve DBC exclusively by using dye-free guidewire technique were included. Complication data on post-ERCP pancreatitis, bleeding, perforation, and cholangitis were extracted. University. Patients undergoing biliary ERCP. ERCP. Success, complication rates.
