Abstract

Objectives: We assessed the efficacy and safety of pancreatic stent-assisted needle-knife precut papillotomy (NKPP) for patients having difficulty in deep cannulation into the bile duct. Patients and Method : Between Jonuary 2001 and October 2006, a total of 682 ERCPs for deep cannulation into the bile duct were performed. Of these ERCPs, 72 cases were unsuccessful by the routine method. 62patients were underwent pancreatic stent-assisted NKPP. Results : Success rates of deep cannulation into bile duct was 94%. Complications included pancreatitis in 2patients (3.2%). Conclusion : Pancreatic stent assisted NKPP was fairly safe and effective for patients having difficulty in deep cannulation into the bile duct.
