Stopped: The data from the interim analysis showed a opposite trend predicting possible of benefit of indomethacin and conditional power analysis revealed a low probability of confirming the benefit of diclofenac if this trial will be continued.
Post-ERCP pancreatitis (PEP) is the most common complication after ERCP, which was associated with occasional mortality, prolonged hospital days and increased health costs. Some studies investigated the effectiveness of different Nonsteroidal antiinflammatory drugs (NSAIDs) for prevent PEP. However, several high-quality RCTs and meta-analyses consistently demonstrated only100mg rectal indomethacin or diclofenac significantly reduced PEP incidence compared with placebos. Thus, European Society of Gastrointestinal Endoscopy, American Society for Gastrointestinal Endoscopy and Japanese Society of Hepato-Biliary-Pancreatic surgery guidelines recommended rountine administration of 100mg rectal indomethacin or diclofenac in unselected patients who underwent ERCP. Up to date, the mechanisms of NSAIDs in preventing pancreatitis were not fully elucidated. Diclofenac and Indomethacin showed similar inhibitory effects in phospholipase A2 and cyclooxygenase pathways. And the peak concentration of diclofenac and indomethacin both occurs between 30 and 90 min after rectal administration. However, diclofenac may be a stronger inhibitor of other pancreatitis-related imflammatory siginals (e.g. nuclear factor kappa-B) than indomethacin. Recently, several meta-analyses found 100mg rectal diclofenac to be more efficacious than 100mg rectal indomethacin. Despite these data, there is no conclusive evidence to prove that rectal diclofenac could provide incremental benefits over indomethacin from high-quality randomized, controlled trials. Therefore, the investigators conducted a multicenter, double-blind, randomized, controlled clinical trial to evaluate the efficacy of rectal diclofenac versus indomethacin for the prevention of post-ERCP pancreatitis in average-risk patients.
