Prevention of post-endoscopic retrograde cholangiopancreatography pancreatitis: a cost-effectiveness analysis.

Objectives: The aim of the present study was to perform a comparative cost-effectiveness analysis of the different strategies used to prevent post-endoscopic retrograde cholangiopancreatography (ERCP) acute pancreatitis.

Methods: We performed a cost-effectiveness decision analysis of 4 prophylactic strategies (nonsteroidal anti-inflammatory drugs or NSAIDs, pancreatic stent, stent plus rectal indomethacin, and no prophylaxis) in a simulated cohort of 300 patients during 1 year. Treatment effectiveness was defined as the number of patients who did not develop post-ERCP pancreatitis.
