title: [Is routine intra-operative cholangiography in laparoscopic cholecystectomy truly unnecessary?].
abstract: The introduction of laparoscopic cholecystectomy as method of choice for gall stone treatment reopened the question whether to continue with routine intraoperative cholangiography or to switch over to a selective indication. In order to set an accurate indication for selective intraoperative cholangiography it was our goal to develop a tool for preoperative identification of patients with a high risk of common bile duct stones. A preoperative score, indicating the risk of common bile duct stones, was designed. A history of jaundice, elevated levels of bilirubin, alkaline phosphatase, amylase (serum), ALAT (GPT) or ASAT (GOT), a common bile duct wider than 10 mm or containing concrements and multiple gallstones smaller than 10 mm were valued as risk indicators, whereas normal wide bile duct, large or solitary gallstones were valued as decreasing the risk of common bile duct stones. The retrospective screening of 289 consecutive conventional cholecystectomies (1986-1990) for these risk indicators demonstrated a good correlation of the risk score with the occurrence of common bile duct stones. A prospective application of the score, with improved ultrasound examination and routine preoperative intravenous cholangiography, mandatory for laparoscopic cholecystectomy at our institution, will define the high risk group definitely and allow an accurate selective use of intraoperative cholangiography.
