Brief Summary:
Post-endoscopic retrograde cholangiopancreatography(ERCP) pancreatitis (PEP)remains the most frequent adverse event of ERCP. Rectal indomethacin, as one kind of classic NSAIDs, has been proved to be effective in reducing the incidence of PEP. It has been widely used to prevent PEP in patients, especially those with potentially high risks of PEP. However, rectal indomethacin can not completely eradicate the occurrence of PEP. The rate of PEP in patients receiving indomethacin ranges from 3.2% to 9.2%. The risk factors of PEP in patients receiving rectal indomethacin remains unclear. The aim of the study was to identify potential risk factors in high-risk patients whose received administration of prophylactic rectal indomethacin after ERCP.

Indomethacin Group

All the patients with high risks of PEP received administration of one single dose of 100mg rectal indomethacin after ERCP.

Patients were considered high risk of PEP if they met one of the following criteria: clinical suspicion of sphincter of Oddi dysfunction, a history of PEP, pancreatic sphincterotomy, precut sphincterotomy, ≥8 cannulation attempts, cannulation time≥10 minutes; pneumatic dilatation of an intact biliary sphincter, ≥3 inadvertent pancreatic duct cannulation, opacification of pancreatic acini, or the acquisition of a cytologic specimen from the pancreatic duct with the use of a brush or forceps.

Primary Outcome Measures :
  1. Overall PEP rate [ Time Frame: 1 year ]
    PEP was defined if patients experienced abdominal pain for more than 24h after procedure, accompanying with amylase or lipase ≥ 3 times equal to the upper limit of normal value.

Secondary Outcome Measures :
  1. The rate of moderate-severe pancreatitis [ Time Frame: 1 year ]
  2. Overall ERCP-related complication rate [ Time Frame: 1 year ]
