Core Tip

Core Tip: The present systematic review and meta-analysis shows that the use of non-steroidal anti-inflammatory drugs reduced the incidence of post-endoscopic retrograde cholangiopancreatography pancreatitis (PEP). This review is the first to be carried out in Latin America with a large number of randomized controlled trials. The present study shows that rectal administration of diclofenac and indomethacin before endoscopic retrograde cholangiopancreatography can reduce the incidence of mild PEP in high, medium and low risk patients.
