Objective To report on the experiences related to diagnosing and managing the bile duct injury in laparoscopic cholecystectomy. Methods To analyse retrospectively the diagnostic and treating experience in 23 cases of bile duct injury. Results Twelve cases of the common bile duct injury, 6 cases of transection of common bile duct, 2 cases of transection injury of common hepatic duct, one case of transec-tion of right hepatic duct, one case of transverse clip block of common bile duct, perforation in each of common bile duct and common hepatic duct. Eleven cases of accessory hepatic duct injury, including one case of aberrant bile duct injury, 7 cases of tiny accessory hepatic duct injury and 3 cases of thick accessory hepatic duct injury. All cases in this group were cured. Conclusion Comparing with LC and open cholecystectomy, occult bile duct injury is more readily to happen in LC with more difficulty in repairment and poor prognosis. Therefore we should strictly select the appropriate operative manual according to patient' s situation.
