Core Tip
Core tip: This retrospective single center analysis of outcomes of early needle-knife fistulotomy (NKF) and double-guidewire technique (DGT) revealed that early NKF has a higher success rate of selective biliary cannulation with a lower incidence of post-endoscopic retrograde cholangiopancreatography pancreatitis and shorter procedural time than DGT in patients with repetitive unintentional pancreatic cannulations.
