Characteristics of bile duct injury induced by laparoscopic cholecystectomy： a single center report

Abstract

Objective To study the characteristics and changes of bile duct injury induced by lapa- roscopic cholecystectomy （LC） in recent years. Methods The clinical data of patients who underwent LC between October 1992 and June 1998 （ early group） were compared with those between June 2003 and March 2009 （recent group）. Results Of 18,613 cases in recent group, the bile duct injury occurred in 11 cases （0.06%） , which included 2 cases of bile duct transection （ occurred during open cholecystectomy in 1 case）, 3 cases of dissociation impairment,-2 eases of electric coagulation injury （1 in common hepatic duct, the other accessory hepatic duct）, 2 cases of partial shearing in common bile duct, 1 case of accessory he- patic duct transection, 1 case of suture injury in common hepatic duct during open eholecystectomy. In 11, 796 cases of early group, bile duct injury occurred in 15 cases （0.13%） , including 6 cases of bile duct transection, 6 cases of electric coagulation injury to lateral extrahepatic bile duct and 3 cases of dissociation impairment of bile duct. Injury-rate.of bile duct in recent group was significantly lower than that of the early group （χ2 = 3.92, P = 0. 04784）. Conclusion The incidence of bile duct injury induced by LC in recent years is significantly lower than that in years before, so is the severity of injury, while the types of bile duct injury are increasing. Individualized management can prevent further injury to the bile duct, as well as post- operative complications. Key words: Cholecystectomy,laparoscopic ; Bile duct injury
