Core Tip

Core Tip: Needle-knife fistulotomy (NKF) is used as a rescue technique for difficult cannulation. However, the data are limited regarding the use of NKF for primary biliary cannulation, especially when performed by beginners. Our retrospective study aims to assess the effectiveness and safety of primary NKF for biliary cannulation, and the role of the endoscopist’s expertise. The incidence rate of post-endoscopic retrograde cholangiopancreatography pancreatitis was significantly affected by the endoscopist’s expertise level in patients who received conventional cannulation with sphincterotomy, but not in those who received NKF. Primary NKF may be effective and safe in achieving ductal access in patients with naïve papilla, regardless of experience.
