    Abstract:
    BACKGROUND: Acute pancreatitis is one of the most common complications of endoscopic retrograde cholangiopancreatography (ERCP). Whether the prophylactic administration of rectal non-steroidal anti-inflammatory drugs (NSAIDs) peri-ERCP is effective in preventing post-ERCP pancreatitis (PEP) remains controversial. The aim of this study was to assess the effect of rectal NSAIDs on PEP. METHODS: A systematic search of literature databases (Cochrane Library, PubMed, EMBASE, and Web of Science) was performed to identify eligible randomized controlled trials (RCTs). The Jadad score for assessing risk of bias was used to evaluate the quality of included studies. The primary endpoint of the study was efficacy for PEP prevention. Sub-analyses were performed to determine the risk reduction for different NSAID types, for general vs. high-risk patients, by timing of administration and for moderate to severe PEP. RESULTS: Twelve RCTs, including a total of 3989 patients, were identified and included in the analysis. The risk of PEP was lower in the NSAIDs group than in the placebo group (RR 0.52; 95% CI 0.43-0.64; P < 0.01). The risk of moderate to severe PEP was also lower in the NSAIDs group. (RR 0.44; 95% CI 0.28-0.69; P < 0.01). There was no difference in efficacy between rectal indomethacin and diclofenac, nor between pre-ERCP and post-ERCP administration timing of rectal NSAIDs. CONCLUSIONS: A single rectal dose of NSAIDs is effective in preventing PEP both in high-risk and in unselected patients, regardless of timing of administration (pre- or post-ERCP) and NSAID type (indomethacin or diclofenac).
