Prophylaxis of pancreatitis with intravenous ketoprofen in a consecutive population of ERCP patients: a randomized double-blind placebo-controlled trial.

Background Acute pancreatitis is the most common complication after ERCP, occurring in about 4 % of the procedures. Only the placement of pancreatic duct prosthesis and the use of nonsteroidal anti-inflammatory drugs (NSAIDs) have shown benefit in the prevention of post-ERCP pancreatitis (PEP). Although the benefit of rectal administration of indomethacin or diclofenac is recommended by some studies and society guidelines especially in a selected group of high-risk patients, there is so far, no standardization of time or route of NSAID administration.
