Ice Cold Water Flushing of the Ampulla After Endoscopic Sphincterotomy to Reduce Post-ERCP Pancreatitis

Endoscopic retrograde cholangiopancreatography (ERCP) is an essential diagnostic and therapeutic tool used to manage diseases of the pancreatic and biliary systems. During the procedure, an upper endoscope is used to reach the major duodenal papilla, and a contrast material is injected into the ducts for radiologic imaging. In an endoscopic sphincterotomy, a specialized knife cuts the biliary sphincter to treat papilla conditions or facilitate therapeutic interventions. The most common complication following an ERCP is pancreatitis, carrying an incidence rate of 3.5% to 9.7%. Standard preventive strategies currently include careful patient selection, rectal administration of NSAIDs (like indomethacin or diclofenac), aggressive intravenous hydration, and pancreatic stent placement. The Innovation: Flushing the ampulla with ice-cold water after a sphincterotomy is a safe,easy, and cost-effective evolving intervention. While initial data demonstrates its safety,there is a clear deficiency in multicenter randomized trials assessing its overall clinical effectiveness, and no such studies have been conducted in the Gulf region. The primary goal of this study is to evaluate the effectiveness of ice-cold water flushing ofthe ampulla after endoscopic sphincterotomy in reducing the incidence of post-ERCP pancreatitis.

Comparative Effectiveness Between Indomethacin and Pancreatic Stenting in the Prevention of Post ERCP Pancreatitis

Post ERCP pancreatitis (PEP) occurs in 4 to 5% of patients and is associated with significant morbidities and occasional mortalities. The use of rectall administered indomethacin and pancreatic duct stent (PDS) placement have independently been proven to reduce PEP. The comparative effectiveness of the two methods has however not been studied. It is argued that in the context of indomethacin, the placement of a PDS is unnecessary. Advocates for PDS insertion however believe that mechanical decompression of the pancreatic duct is critical in the prevention of pancreatitis. The investigators propose a multi-centre randomised controlled trial to compare the use of rectal indomethacin to PDS insertion in high risk patients in the prevention of PEP.
