Rectal NSAIDs With/Without PD Stent for PEP Prevention

Официальное название

Rectal Non-steroid Anti-inflammatory Drugs With or Without Prophylactic Pancreatic Duct Stent for Prevention of Post-ERCP Pancreatitis: a Multicenter, Randomized, Non-inferiority Trial

Обзор

Pancreatitis is the most common and serious complication following post-endoscopic retrograde cholangiopancreatography (ERCP) and is associated with occasional mortality, extended hospital stays, and increased healthcare expenses. Rectal non-steroidal anti-inflammatory drugs (NSAIDs) and pancreatic duct stent (PDS) placement were demonstrated to be effective strategyies to reduce PEP incidences, particlularly in high-risk patients for post-ERCP pancreatitis (PEP). Rectal NSAIDs were easy-to-use and safe, while PDS placement were technically complex and carried higher risks of adverse events. A previous network meta-analysis suggested rectal NSAIDs in combination with PDS placement did not differ from rectal NSAIDs alone in PEP prevention. To invesigate if rectal NSAIDs alone could obivate the need of PDS placement, a recent trial from Elmunzer et al. conducted a randomized trial to investigate if rectal NSAIDs alone was non-inferior to the combination of NSAIDs with PDS in high-risk patients. The trial found that the PEP incidence rate in combination group was significantly lower than that in NSAIDs alone group. However, post-hoc analysis of the study suggested that the combination strategy conferred significant benefits only in high-risk patients with pancreatic duct (PD) wire passage, but not in those with other risk factors. Therefore, we hypothesized that rectal NSAIDs alone may obivate the need of PDS in high-risk patients without PD wire passages. Here, we conducted a multicenter, randomized and non-inferiority trial to investigate whether rectal NSAIDs alone is non-inferior to NSAIDs plus PDS placement in high-risk patients without PD wire passages.

Вмешательства

• Препарат NSAIDs
  All patients without contraindications should receive 100mg rectal indomethacin or diclofenac within 30mins before ERCP procedure
• Устройство NSAIDs plus PDS
  All patients without contraindications should receive 100mg rectal indomethacin or diclofenac within 30mins before ERCP procedure. When eligibility is met, PDS placement will be performed by ERCP colonoscopists.

Критерии участия

Критерии включения

• 18-90 years old patients with native papilla who planned to undergo ERCP
• high-risk patients for post-ERCP pancreatitis must meet one or more following criteria: clinical suspicion of sphincter of Oddi dysfunction, a history of PEP, pancreatic sphincterotomy, precut sphincterotomy, difficult cannulation (>5 cannulation attempts, or >5mins cannulation time, or >1 unintentional pancreatic duct cannulation), or ballon dilatation of an intact biliary sphincter ≤ 1 min, double-wire cannulation.
