title: Prospective study of scoring system in selective intraoperative cholangiography during laparoscopic cholecystectomy.
abstract: OBJECTIVE
  To evaluate of scoring system in predicting choledocholithiasis in selective intraoperative cholangiography (IOC) during laparoscopic cholecystectomy (LC).
  
  
  METHODS
  The scoring system of predicting choledocholithiasis was developed during the retrospective study in 264 cases, and was tested in 184 to evaluate its predictive value in choledocholithiasis.
  
  
  RESULTS
  The scoring system was developed in a retrospective study of 264 cases, the statistical analyses showed the predictive factors included sex, transaminase levels, alkaline phosphatase level, bilirubin level, and common bile duct diameter on ultrasonography. The scoring system was used in 184 cases prospectively, of which, 3 of 162 (1.9 %) cases scoring <3 had choledocholithiasis, 17 of 22 (77.3 %) cases scores >=3 had choledocholithiasis. A case of scores >=3 or more prospectively should be considered highly intraoperative cholangiography during laparoscopic cholecystectomy.
  
  
  CONCLUSIONS
  The scoring system can predict choledocholithiasis and is helpful in selection patients for intraoperative cholangiography.
