UNLABELLED: The aim of this study was to evaluate the effectiveness and the safety of allopurinol in the prophylaxis of post-endoscopic retrograde cholangiopancreatography (ERCP) pancreatitis. METHODS: : We used the method recommended by the Cochrane Collaboration to perform a meta-analysis of randomized controlled trials (RCTs) of allopurinol in the prevention of post-ERCP pancreatitis (PEP), including 6 RCTs conducted all over the world. RESULTS: : Six RCTs totaling 1554 patients undergoing ERCP were included. When the RCTs were analyzed, odds ratios of allopurinol were 0.74 (95% confidence interval [CI], 0.37-1.48; P = 0.40) for PEP, 0.87 (95% CI, 0.33-2.28; P = 0.78) for severe PEP, 0.88 (95% CI, 0.37-2.11; P = 0.78) for post-ERCP hyperamylasemia, and 0.19 (95% CI, 0.01-3.91; P = 0.28) for case-fatality ratio of PEP, thus indicating no beneficial effects of allopurinol on acute pancreatitis, PEP death rate, and hyperamylasemia. No evidence of publication bias was found. CONCLUSIONS: : Allopurinol cannot prevent the pancreatic injury after ERCP. Allopurinol is not recommended in the prophylaxis of PEP.
