title: "Diagnostic value of MRCP in biliary pancreatitis: result of long-term follow-up".
abstract: OBJECTIVE
  Magnetic resonance cholangiopancreatography (MRCP) has increasingly been used to evaluate the common bile duct. This study was to determine the role of MRCP instead of endoscopic retrograde cholangiopancreatography (ERCP) in the management of patients with acute biliary pancreatitis.
  
  
  METHODS
  A total of 81 patients with mild or moderate biliary pancreatitis who underwent MRCP and were treated in our department with selective ERCP between May 2001 and July 2007 were entered into a prospective database.
  
  
  RESULTS
  MRCP was considered abnormal in 13 patients. Ten patients underwent ERCP. Three patients did not undergo ERCP due to protocol violations. In nine patients, stone extraction was performed. The remaining patient who had dilatation of the CBD underwent ES. The false positive rate of MRCP was 10%. The median follow-up of overall patients was 36 months (range 23-99 months). The patients with normal MRCP had a median follow-up of 39.5 months (range 23-99 months). During the follow-up period in the normal MRCP group, five patients were diagnosed with recurrent biliary pancreatitis, of which three underwent ERCP (7.4%). There was no disease-related mortality during this period.
  
  
  CONCLUSIONS
  In conclusion, the use of MRCP in acute biliary pancreatitis is safe and may be recommended as a tool to aid in the selective use of ERCP.
