The significance of intraoperative cholangiography in laparoscopic cholecystectomy / 重庆医科大学学报

ABSTRACT

Objective:To evaluate the value of intraoperative transcystic cholangiography(IOC) during laparoscopic cholecystectomy(LC).Methods:IOC was conducted in 56 patients who underwent LC because of cholelithiasis with chronic or acute cholecystitis and biliary pancreatitis.The results were analyzed.Results:Cannulation was successfully completed in 54 out of 56 patients,and the success rate was 96.4%.All 54 patients underwent satisfactory visualization.The common bile duct stones were detected in 5 patients by IOC,and 2 of them were converted to common bile duct exploration and T-tube drainage by open cholecystectomy;3 of them were converted to common bile duct exploration and T-tube drainage by laparoscopic cholecystectomy.2 cases were found to have abnormal cystic duct by IOC,and 4 cases were detected for the biliary anatomy by IOC.The average time of IOC was about(15.5?3.7)minutes.No complication occurred.Conclusion:IOC is a safe and convenient procedure with a high success rate,and it can provide clear films of biliary tree.The benefit of IOC is the detection of common bile duct and cystic duct stones and abnormal biliary anatomy.It can reduce the rate of retained common bile duct stones and bile duct injuries,and increase the early identification of bile duct injuries.Therefore IOC can improve quality and security of LC.
