title: Preoperative evaluation of the probability of common bile duct stones. French Association for Surgical Research.
abstract: BACKGROUND
  This study was done to determine if certain criteria could predict the presence of common bile duct stones in patients with symptomatic gallstones. It was hoped that patients could be identified in whom intraoperative cholangiography was unnecessary.
  
  
  METHODS
  One hundred seventy-five patients, from 15 surgical centers, were prospectively enrolled. For each patient, the preoperative score (Huguier score) previously published was calculated according to clinical and ultrasound data: age, diameter of the common bile duct, diameter of the smallest gallstone, history of biliary colic, and acute cholecystitis. All patients underwent an open cholecystectomy and an intraoperative cholangiography. The absence or presence of a common bile duct stone was evaluated during the operation, if necessary, after an instrumental investigation of the common bile duct.
  
  
  RESULTS
  Ultrasound was not interpretable in eight (5 percent) of 175 patients. Final analysis was made from the charts of the 167 remaining patients. Thirty (18 percent) had common bile duct stones. When the score was equal to or greater than 3.5, the risk of having a common bile duct stone was 24 percent (27 of 111). When the score was less than 3.5, this risk was 5 percent (three of 56).
  
  
  CONCLUSIONS
  Huguier's score is well assessed and can be safely used. Intraoperative cholangiography could be avoided in 33 percent of patients when the score is less than 3.5 (56 of 167).
