title: [Cholangiography: a routine test in elective cholecystectomy?].
abstract: A prospective study to evaluate the selective or routine use of intraoperative cholangiography on elective cholecystectomy was performed. 178 patients were studied, listing criteria to explore the biliary tract with the cholangiographic aspects. The criteria showing choledocholithiasis were the alkaline phosphatase and/or bilirubin increase, dilated common bile duct, large cystic duct, small stones and pancreatitis or jaundice on the past history. The patients were divided in 4 groups: 1) No criteria: 61 (34.3%); 2) One criterion: 53 (30%); 3) Two criteria: 22 (12.3%); 4) More than two criteria: 42 (23.4%). The false-positive was 1.6% to the first group, 3.8% to the group 2 and 0% to the other groups. We concluded that the intraoperative cholangiography must be achieved on patients that have at least one choledocholithiasis criterion.
