Objective To reduce or prevent the incidence of bile duct injury in the laparoscopic cholecystectomy,and reduce the postoperative complications of Bile duct injury in the laparoscopic cholecystectomy by time and exact treatment during the surgical procedure.Methods We retrospectively analyzed the clinical data of 8700 cases of LC, including 12 cases of bile duct injury, from September 1991 to today. The corresponding treatment was used in LC to avoid bile duct injury, when bile duct injury occurred, the injury was recognized and immediately repaired by surgery. Result The mean follow-up period after surgery was 5-10 years,all 12 patients with bile duct injury were cured and discharged. Conclusions We should correctly handle the relationship of various duct and avoid burn or cut duct for reducing incidence of the extrahepatic bile duct injury. Correct treatment can reduce or avoid the incidence of postoperative complications.
