预防性应用糖皮质激素不能预防ERCP后的胰腺炎：一项随机对照实验的荟萃分析

Background: Data regarding the use of corticosteroids for the prevention of post-endoscopic retrograde cholangiopancreatography (ERCP) pancreatitis are conflicting. The aim of this meta-analysis was to compare corticosteroids with placebo for prevention of post-ERCP pancreatitis. Methods: Multiple databases including MEDLINE, EMBASE, Cochrane controlled trials register, the Cochrane Library, Science Citation Index, Google Scholar and Google updated to June 2007 were searched to retrieve the relevant randomized controlled trials. Primary outcome measure was post-ERCP pancreatitis. Results: Six randomized controlled trials involving 2,448 patients were identified. The analysis showed that corticosteroids did not prevent post-ERCP pancreatitis (OR 1.13:95% CI [0.88,1.46]). Subsequent sensitivity and subgroup analyses according to different criteria all confirmed these results. Conclusions: Based on available evidence, prophylactic corticosteroids do not reduce the incidence of post-ERCP pancreatitis.
