ERCP wasperformed and the papilla vater was shown with redness and swelling. Though wesuspected an illcarcerated stone, carlrlulation into the common bile duct was done verysmoothly and no stolle was detected. However, as soon as we finished the examination, severe epigastric pain and back pain occured, suddenly. We noticed the films showing astone incarcerated into the main pancreatic duct. So, we performed emergent EST alldremoved the stone. Clinical course aftr EST was good, then laparoscopic cholecystectomywas underwent. alld the both were cholesterol stones.
