Abstract

Post-ERCP Pancreatitis: Mechanisms, Risk Factors, and Prevention

Majed El Zouhairi, David Swartz and Tilak Shah

Acute pancreatitis is the most common complication of endoscopic retrograde cholangiopancreatography (ERCP), occurring in up to 30 to 40% of high risk patients. The most prominent theories of post-ERCP pancreatitis (PEP) pathogenesis include mechanical trauma to the papillary orifice, hydrostatic injury, and enzymatic injury from activated proteolytic enzymes introduced from the duodenum. Investigators have proposed a number of patient-related, procedure-related, and physician-related risk factors for PEP. However, when evaluated in large prospective trials, the role of these factors in increasing risk of PEP is inconsistent. Placement of a pancreatic duct stent and administration of rectal non-steroidal anti-inflammatory drugs (NSAIDs) are the two interventions with the greatest body of evidence supporting efficacy in PEP prevention.
