Core Tip
Core Tip: The use of a novel contrast-enhanced catheter improved the bile duct cannulation rate when using the standard technique and reduced the frequency of cases with difficult cannulation. These advantages were particularly notable in procedures performed by experts. Further, its application by experts has shown promise in reducing the frequency of difficult cannulation, underscoring its utility in clinical practice.
