The experience on prevention of transecting injury of the extrahepatic bile duct in laparoscopic cholecystectomy

To study the feasible methods to prevent transecting injury of the extrahepatic bile duct (EHBD) during laparoscopic cholecystectomy (LC). Methods: ①The cystic infundibulum shoud be dissected at first. The junction of the cystyic infundibulum and cystic duct is an important anatomic marker to identify the cystic duct and prevent mistaking the EH BD for the cystic duct and transecting the EXBD.②bluntly dissecting the Calot triangle close to the gallbladder wall,side -viewing the common hepatic and common bile duct,transecting the cystic artery and fiber tissue around the gallbadder,all of these are mandatory toavoid transection of the common hepatic duct and right or left hepatic duct which join lowly.Results:4 transectinies injuryg of the EHBD were documented realtad to unexperience or no following the principle described. Conclusion: It is a uncontroversy principle to dissect the cystic infundibulum and then expose the junction of the cystic infundibulum and cystic duct to confirm the cystic duct- Bluntly dissecting of the Calot triangle close to the gallbladderwall is a feasible step to avoid transecting the EHBD.
