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


PMID 25406954

Abstract

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. 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. The baseline costs of each strategy were as follows: rectal NSAID $359,098, pancreatic stent $426,504, stent plus rectal indomethacin $479,153, and no prophylaxis $491,275. The mean number of cases developing post-ERCP pancreatitis was 16, 21, 23, and 37 for the strategies rectal NSAID, pancreatic stent, stent plus rectal indomethacin, and no prophylaxis, respectively. Taking rectal NSAID prophylaxis as the reference strategy, the odds ratio of an episode of post-ERCP acute pancreatitis after pancreatic stent placement was 1.33 (95% confidence interval [CI], 0.68-2.61); after stent plus indomethacin, it was 1.40 (95% CI, 0.72-2.73), and after no prophylaxis, it was 2.49 (95% CI, 1.35-4.59). Rectal NSAID administration proved to be the most cost-effective prophylactic strategy used to prevent post-ERCP pancreatitis. The strategy of no prophylaxis for this complication should be avoided.
