PURPOSE One of the major complications in laparoscopic cholecystectomy (LC) is biliary tract injury. We report here on the effectiveness of preoperative examinations in case with abnormal branching of the cystic duct.
MATERIAL AND METHODWe studied 861 patients who underwent LC from December 2000 to 0ctober 2013. Using drip infusion cholecystoangiography-computed tomography (DIC-CT), magnetic resonance cholangiopancreatography (MRCP) and endoscopic retrograde cholangiopancreatograhpy (ERCP), branching of the cystic duct was evaluated before surgery.
RESULT Anatomic variants of the cystic duct were observed in twelve patients (1.4%). Abnormal branch types were as follows five cases of the cystic duct branching from the anterior right hepatic duct, four cases from the posterior right hepatic duct, one case from the duct of caudate lobe, one case from the accessory hepatic duct, and one case from the accessory cholecystohepatic duct. All procedures were performed without any intraoperative complications such as bile duct injuries.
CONCLUSION Adequate preoperative study is required to recognize abnormal branching of the cystic duct, which may allow the prevention of injury to the biliary tract during the procedure.
