Magnetic resonance cholangiopancreatography to analyze the risk factor before laparoscopic cholecystectomy

Objective To assess the diagnostic value of MRCP before LC. Methods 944 cases with chronic calculous cholecystitis underwent MRCP before LC from June 2004 to June 2007 in our department, incidence rate of eholecystolithiasis together with common bile duct stones and incidence rate of anatomic abnormity of bile duct were collected. Results The incidence rate of cholecystolithiasis together with common bile duct stones were 8.1% （77/944） ,and the oceurence of ACBDS were 1.2% （11/944）. The incidence rate of anatomic abnormity of bile duct were 3.7% （35/944）. Conclusion MRCP can not only offer a excellent diagnostic value of ACBDS and anatomic abnormity of bile duct, but also reduce the occurrence of CBDS remainder and iatrogenic bile duct injuries.
