Bile duct injuries are the most frightening complications in laparoscopic cholecystectomy surgery. It is thought that incomplete surgical field dissection causes these situations. In this case, cholelithiasis and minimal intrahepatic biliary duct dilatation were determined on ultrasonography. None of biliary duct variation was determined on magnetic resonance cholangiopancreatography (MRCP). According to these results, it was decided to perform laparoscopic cholecystectomy. Surgery was performed according to the "Critical View of Safety" principles. Thus, the accessory bile duct could be seen and surgery was completed without any complication. It was aimed to demonstrate that the "Critical View of Safety" principles can prevent ductal complications in situations where preoperative MRCP cannot determine bile duct anomalies. Sensitivity of preoperative tests is not 100% for biliary duct anomalies. Therefore, to prevent bile duct injuries, we should perform laparoscopic cholecystectomy according to the "Critical View of Safety" principles for all patients.
