Moderate and severe postendoscopic retrograde cholangiopancreatography pancreatitis despite prophylactic pancreatic stent placement: The effect of early prophylactic pancreatic stent dislodgement

摘要

BACKGROUND:Placement of prophylactic pancreatic stents (PPS) is a method proven to reduce the rate and severity of postendoscopic retrograde cholangiopancreatography (ERCP) pancreatitis (PEP) in high-risk patients; however, PPS do not eliminate the risk completely. Early PPS dislodgement may occur prematurely and contribute to more frequent or severe PEP.
