Analysis Of The Risk Factors For Severity In Post Endoscopic Retrograde Cholangiopancreatography Pancreatitis: The Indication Of Prophylactic Treatments

AIMTo determine the risk factors of severe post endoscopic retrograde cholangiopancreatography pancreatitis (sPEP) and clarify the indication of prophylactic treatments.METHODSAt our hospital, endoscopic retrograde cholangiopancreatography (ERCP) was performed on 1507 patients from May 2012 to December 2015. Of these patients, we enrolled all 121 patients that were diagnosed with post endoscopic retrograde PEP. Fourteen of 121 patients diagnosed as sPEP were analyzed.RESULTSForty-one patients had contrast media remaining in the pancreatic duct after completion of ERCP. Seventy-one patients had abdominal pain within three hours after ERCP. These were significant differences for sPEP (P < 0.05). The median of Body mass index, the median time for ERCP, the median serum amylase level of the next day, past histories including drinking and smoking, past history of pancreatitis, sphincter of Oddi dysfunction, whether emergency or not, expertise of ERCP procedure, diverticulum nearby Vater papilla, whether there was sphincterotomy or papillary balloon dilation, pancreatic duct cannulation, use of intraductal ultrasonography enforcement, and transpapillary biopsies had no significant differences with sPEP.CONCLUSIONContrast media remaining in the pancreatic duct and the appearance of abdominal pain within three hours after ERCP were risk factors of sPEP.
