[Use of preoperative infusion cholangiography before laparoscopic cholecystectomy].

In the present study, we intend to evaluate whether intravenous cholangiography, performed on a routine basis in the preoperative period, in addition ultrasonography, history or elevations of serum bilirubin and alkaline phosphatase, provides any supplementary information in detecting patients with asymptomatic calculi in the common bile duct before laparoscopic cholecystectomy is carried out. Therefore, 513 patients were included in a retrospective analysis. From our data, we conclude that preoperative intravenous cholangiography cannot be recommended, when costs and risks and a potential benefit for the patient are considered.
