History of Post-Endoscopic Retrograde Cholangiopancreatography Pancreatitis and Acute Pancreatitis as Risk Factors for Post-ERCP Pancreatitis

摘要

BackgroundPrevious pancreatitis is a definite patient-related risk factor for pancreatitis after endoscopic retrograde cholangiopancreatography (post-ERCP pancreatitis: PEP). However, the effects of differences in the history of PEP and acute pancreatitis on the occurrence of PEP have not been fully investigated. We examined the relationship between previous PEP or previous acute pancreatitis and procedural factors associated with PEP.
