RESUMO
BACKGROUND: Biliary duct injury (BDI) is one of the most common complications in laparoscopic cholectecystomy (LC), in this study, we have tried to place an illuminating optical fiber via endoscopy in the CBD during LC, the biliary duct anatomy can be clearly delineated, thus CBD injury is avoided. METHODS: Sixteen patients with chronic cholecystitis or/and cholelithiasis from February 2007 to June 2008 were performed LC with placement of optical fiber in CBD, the fiber with cold light illuminates the whole extrahepatic biliary system. Three 6-mm titanium clips were applied to the soft tissue surrounding the hepatic duct, CBD and the cystic duct confluence with CBD, respectively; one titanium clip was applied to the surface of cystic duct near the infundibulum of gallbladder. The cytic duct, CBD and common hepatic duct were clearly identified and delineated in the operating field and LC was performed. RESULTS: All the 16 patients were performed LC using this procedure successfully, there were no LC-related complications, nor complications related to endoscopic retrograde cholangiopanceatography (ERCP). CONCLUSIONS: The endoscopically placed optical fiber in the CBD can clearly identify the CBD, Calot's triangle and the common hepatic duct, this can reduce the bile duct injury in LC and imporve the safety of LC.
