Core Tip

Core Tip: This observational study showed that pancreatic stent (PS) placement aids identification of the direction of the common bile duct and increases the success rate of needle-knife papillotomy in patients with difficult biliary cannulation, especially with less experienced operators. Significant bleeding during needle-knife papillotomy and in patients with a periampullary diverticulum can detract from the success of the procedure. Although PS placement tends to improve the success rate of needle-knife papillotomy, randomized controlled trials are required to validate the results.
