[The Latest Knowledge on Endoscopic Retrograde Cholangiopancreatography-related Pancreatitis].

ERCP has been established as a golden diagnostic and therapeutic modality in various pancreatobiliary diseases, including gallstones and malignancy. On the other hand, ERCP is a relatively invasive procedure with radiation hazards and major complications. Among the major complications, ERCP-related pancreatitis has been reported in more than 14.7% of high-risk patients, which might lead to extended hospitalization and a substantial burden for both patients and physicians. Recent guidelines have defined the high-risk factors for ERCP-related pancreatitis. In addition, several outstanding studies have shown that rectal non-steroidal anti-inflammatory drugs, aggressive hydration with lactated Ringer's solution, and pancreatic stents can reduce ERCP-related pancreatitis in high-risk patients or all patients. A prevention algorithm for ERCP-related pancreatitis was provided based on advanced research.
