Pancreatitis is the most common complication of endoscopic retrograde cholangiopancreatography (ERCP). Risk factors for post-ERCP pancreatitis (PEP) are both patient-related and procedurerelated. Identification of patients at high risk for
PEP is important in order to target prophylactic measures. Prevention of PEP includes administration of nonsteroidal inflammatory drugs (NSAIDs), use of specific cannulation techniques, and placement of temporary pancreatic stents.
   The aim of this guideline commissioned by the European Society of Gastrointestinal Endoscopy (ESGE) is to provide practical, graded, recommendations for the prevention of PEP.
