title: The frequency of bile duct crystals in patients with presumed biliary pancreatitis.
abstract: BACKGROUND
  Previous studies of biliary microlithiasis in acute pancreatitis of uncertain etiology were conducted a few weeks to months after the acute episode. Bile obtained during urgent ERCP (less than 24 hours after admission) was studied for the presence of microlithiasis during the acute phase of acute pancreatitis of suspected biliary origin.
  
  
  METHODS
  Fifteen consecutive patients with acute pancreatitis of suspected biliary origin were recruited from a population of 309 patients with acute pancreatitis (5%) treated during the last 4 years. Patients with gallstones on US and/or ERCP and those in whom the etiology of acute pancreatitis was certain were excluded.
  
  
  RESULTS
  Microlithiasis (mostly calcium bilirubinate granules) was found in 12 (80%) cases. Despite endoscopic sphincterotomy 3 patients died within 2 weeks because of multisystemic organ failure. Among the 12 remaining patients, 2 (16%) developed gallbladder stones and 1 underwent cholecystectomy for cholecystitis (8%) during follow-up. The average length of follow-up was 30 months. No episodes of acute pancreatitis were noted during follow-up.
  
  
  CONCLUSIONS
  In the acute phase of acute pancreatitis of suspected biliary origin, biliary microlithiasis was found in most cases. Endoscopic sphincterotomy appears to protect patients from further episodes of acute pancreatitis.
