Official Title: Primary Needle Knife Fistulotomy Versus Conventional Cannulation Method in Patients With High Risk of Post-endoscopic Retrograde Cholangiopancreatography Pancreatitis: A Multicenter Randomized Control
Brief Summary: The aim of this study are to evaluate the feasibility of needle knife fistulotomy (NKF) as an initial procedure for biliary access in patients with common bile duct stones who are at increased risk for post-endoscopic retrograde endoscopic retrograde cholangiopancreatography (PEP) and to assess the incidence rate of complications including PEP between NKF and conventional cannulation methods.
