Comparative Effectiveness Between Rectally Administered Indomethacin and Pancreatic Stenting in the Prevention of Post Endoscopic Retrograde Cholangio-panceaticography (ERCP) Pancreatitis: a Randomized Trial
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.
⁃ presence of one of the following risk factors for Post ERCP Pancreatitis
• sphincter of Oddi dysfunction
• history of PEP, pancreatic instrumentation or sphincterotomy, precut sphincterotomy,
• difficult cannulation defined by \>5 cannulation attempts
• the use of double wire technique in bile duct access
• at least 2 of the followings including i) female age\<50 ii) 3 pancreatograms iii) acinarization (contrast injection to tail fo pancreas). iv） normal bilirubin； v）guidewire to the tail of pancreas or secondary branches.
