Abstract
There are several causes of post-ERCP pancreatitis (PEP). Three major causes of PEP are (1)Patient-related factors ; (2)Operator-related factors and (3)Technique-related factors. There are several techniques to prevent PEP. In this chapter, I would like to demonstrate and explain how to do endoscopic pancreatitic stenting, especially in the patients with high risk of PEP. Finally, it is demontrated that preventive endoscopic pancreatic stenting is effective to decrease the incidences of PEP by our data and meta-analysis.
