Rectal NSAIDs for the prevention of post-ERCP pancreatitis: a meta-analysis of randomized controlled trials.Surgeon. 2014 Jun; 12(3):141-7.S
BACKGROUND AND PURPOSE
Acute pancreatitis is the most frequent complication of endoscopic retrograde cholangiopancreatography (ERCP). We conducted a meta-analysis to evaluate the efficacy and safety of rectal nonsteroidal anti-inflammatory drugs (NSAIDs) for the prevention of post-ERCP pancreatitis (PEP).
PubMed and Embase databases were searched through April 2013. Results are reported as relative risk (RR) or weighted mean difference (WMD) with 95% confidence interval (95% CI). The primary outcome measure was the incidence of PEP. Secondary outcome measures included the severity of PEP and serum amylase level 2 h, 24 h after ERCP.
Seven trials containing 1846 patients were eligible. Rectal NSAIDs significantly reduced the incidence of PEP (RR 0.45, 95% CI 0.34-0.61, P < 0.001). The results were maintained in subsequent subgroup analysis. Rectal NSAIDs also was associated with a reduction in the incidence of mild PEP (RR 0.54, 95% CI 0.35-0.83, P = 0.005), moderate to severe PEP (RR 0.39, 95% CI 0.22-0.70, P = 0.002), or serum amylase level 2 h after ERCP (WMD -91.09 IU/L, 95% CI -149.78 to -32.40, P = 0.002).
Rectal NSAIDs reduced the incidence and severity of PEP, as well as serum amylase level 2 h after ERCP.
