Objective To explore the types and the clinical value of the abnomalities of the gallbladder and cystic duct. Methods The clinical date of the 8 cases associated with the abnomalities of the gallbladder and cystic duct among the 432 patients who underwent cholecystectomy in our department since 1990 January were analyzed relrospectively. Results Of the 8 cases ,1 case was discovered as gallbladder duplication, 1 as left-sided gallbladder, 2 as cystic duct parallel to CBD ,1 as cystic duct joining to the anterior wall of CBD,1 as double cystic ducts (one duct joining to the common hepatic duct, the other joining to CBD ),1 as gallbladder hepatic duct ,1 as right accessory hepatic duct joining to the cystic duct. 4 patients(50.0%) developed postoperative complications.Conclusions The keys to reduce the morbidity rate of cholecystectomy are carefully assessment and dissection of the Calot′s triangular area, correct management of the cystic duct ,cystic artery ,and the "adhesions".
